Apache/Mongrel Deployment Errors

I am having issues with setting up my apache/mongrel cluster.

I am using FC5, and i currently have 3 mongrels running on port
8000,8001, 8002. I am just testing my apache/mongrel deployment on my
development machine and not online. I have apache 2.2.2, and my
httpd.conf is pretty much the exact default after i yum installed apache
2.2.2. in my /etc/httdp/conf.d , i have myapp.conf, which has:

<VirtualHost *:80>
<Proxy balancer://depot_cluster/>
BalancerMember http://127.0.0.1:8000
BalancerMember http://127.0.0.1:8001
BalancerMember http://127.0.0.1:8002

ProxyPass / balancer://depot_cluster/
ProxyPassReverse / balancer://depot_cluster/
ErrorLog /etc/httpd/logs/depot_error_log
CustomLog /etc/httpd/logs/depot_access_log combined

For reference, my httpd.conf file looks like

This is the main Apache server configuration file. It contains the

configuration directives that give the server its instructions.

See URL:http://httpd.apache.org/docs/2.2/ for detailed information.

In particular, see

URL:http://httpd.apache.org/docs/2.2/mod/directives.html

for a discussion of each configuration directive.

Do NOT simply read the instructions in here without understanding

what they do. They’re here only as hints or reminders. If you are

unsure

consult the online docs. You have been warned.

The configuration directives are grouped into three basic sections:

1. Directives that control the operation of the Apache server process

as a

whole (the ‘global environment’).

2. Directives that define the parameters of the ‘main’ or ‘default’

server,

which responds to requests that aren’t handled by a virtual host.

These directives also provide default values for the settings

of all virtual hosts.

3. Settings for virtual hosts, which allow Web requests to be sent to

different IP addresses or hostnames and have them handled by the

same Apache server process.

Configuration and logfile names: If the filenames you specify for many

of the server’s control files begin with “/” (or “drive:/” for Win32),

the

server will use that explicit path. If the filenames do not begin

with “/”, the value of ServerRoot is prepended – so “logs/foo.log”

with ServerRoot set to “/etc/httpd” will be interpreted by the

server as “/etc/httpd/logs/foo.log”.

Section 1: Global Environment

The directives in this section affect the overall operation of Apache,

such as the number of concurrent requests it can handle or where it

can find its configuration files.

Don’t give away too much information about all the subcomponents

we are running. Comment out this line if you don’t mind remote sites

finding out what major optional modules you are running

ServerTokens OS

ServerRoot: The top of the directory tree under which the server’s

configuration, error, and log files are kept.

NOTE! If you intend to place this on an NFS (or otherwise network)

mounted filesystem then please read the LockFile documentation

(available at

URL:http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile);

you will save yourself a lot of trouble.

Do NOT add a slash at the end of the directory path.

ServerRoot “/etc/httpd”

PidFile: The file in which the server should record its process

identification number when it starts.

PidFile run/httpd.pid

Timeout: The number of seconds before receives and sends time out.

Timeout 120

KeepAlive: Whether or not to allow persistent connections (more than

one request per connection). Set to “Off” to deactivate.

KeepAlive Off

MaxKeepAliveRequests: The maximum number of requests to allow

during a persistent connection. Set to 0 to allow an unlimited amount.

We recommend you leave this number high, for maximum performance.

MaxKeepAliveRequests 100

KeepAliveTimeout: Number of seconds to wait for the next request from

the

same client on the same connection.

KeepAliveTimeout 15

Server-Pool Size Regulation (MPM specific)

prefork MPM

StartServers: number of server processes to start

MinSpareServers: minimum number of server processes which are kept

spare

MaxSpareServers: maximum number of server processes which are kept

ServerLimit: maximum value for MaxClients for the lifetime of the

server

MaxClients: maximum number of server processes allowed to start

MaxRequestsPerChild: maximum number of requests a server process

serves

StartServers 8
MinSpareServers 5

ServerLimit 256
MaxClients 256
MaxRequestsPerChild 4000

worker MPM

StartServers: initial number of server processes to start

MaxClients: maximum number of simultaneous client connections

MinSpareThreads: minimum number of worker threads which are kept spare

MaxSpareThreads: maximum number of worker threads which are kept spare

ThreadsPerChild: constant number of worker threads in each server

StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0

Listen: Allows you to bind Apache to specific IP addresses and/or

ports, in addition to the default. See also the

directive.

Change this to Listen on specific IP addresses as shown below to

prevent Apache from glomming onto all bound IP addresses (0.0.0.0)

#Listen 12.34.56.78:80
Listen 80

Dynamic Shared Object (DSO) Support

To be able to use the functionality of a module which was built as a

DSO you

have to place corresponding `LoadModule’ lines at this location so the

directives contained in it are actually available before they are

used.

Statically compiled modules (those listed by `httpd -l’) do not need

to be loaded here.

Example:

LoadModule foo_module modules/mod_foo.so

LoadModule auth_basic_module modules/mod_auth_basic.so
LoadModule auth_digest_module modules/mod_auth_digest.so
LoadModule authn_file_module modules/mod_authn_file.so

The following modules are not loaded by default:

#LoadModule cern_meta_module modules/mod_cern_meta.so
#LoadModule asis_module modules/mod_asis.so

Load config files from the config directory “/etc/httpd/conf.d”.

Include conf.d/*.conf

ExtendedStatus controls whether Apache will generate “full” status

information (ExtendedStatus On) or just basic information

(ExtendedStatus

Off) when the “server-status” handler is called. The default is Off.

#ExtendedStatus On

If you wish httpd to run as a different user or group, you must run

httpd as root initially and it will switch.

User/Group: The name (or #number) of the user/group to run httpd as.

. On SCO (ODT 3) use “User nouser” and “Group nogroup”.

. On HPUX you may not be able to use shared memory as nobody, and the

suggested workaround is to create a user www and use that user.

NOTE that some kernels refuse to setgid(Group) or semctl(IPC_SET)

when the value of (unsigned)Group is above 60000;

don’t use Group #-1 on these systems!

User apache
Group apache

Section 2: ‘Main’ server configuration

The directives in this section set up the values used by the ‘main’

server, which responds to any requests that aren’t handled by a

definition. These values also provide defaults for

any containers you may define later in the file.

All of these directives may appear inside containers,

in which case these default settings will be overridden for the

virtual host being defined.

ServerAdmin: Your address, where problems with the server should be

e-mailed. This address appears on some server-generated pages, such

as error documents. e.g. [email protected]

ServerAdmin [email protected]

ServerName gives the name and port that the server uses to identify

itself.

This can often be determined automatically, but we recommend you

specify

it explicitly to prevent problems during startup.

If this is not set to valid DNS name for your host, server-generated

redirections will not work. See also the UseCanonicalName directive.

If your host doesn’t have a registered DNS name, enter its IP address

here.

You will have to access it by its address anyway, and this will make

redirections work in a sensible way.

#ServerName www.example.com:80

UseCanonicalName: Determines how Apache constructs self-referencing

URLs and the SERVER_NAME and SERVER_PORT variables.

When set “Off”, Apache will use the Hostname and Port supplied

by the client. When set “On”, Apache will use the value of the

ServerName directive.

UseCanonicalName Off

DocumentRoot: The directory out of which you will serve your

documents. By default, all requests are taken from this directory, but

symbolic links and aliases may be used to point to other locations.

DocumentRoot “/var/www/html”

Each directory to which Apache has access can be configured with

respect

to which services and features are allowed and/or disabled in that

directory (and its subdirectories).

First, we configure the “default” to be a very restrictive set of

features.

Options FollowSymLinks AllowOverride None

Note that from this point forward you must specifically allow

particular features to be enabled - so if something’s not working as

you might expect, make sure that you have specifically enabled it

below.

This should be changed to whatever you set DocumentRoot to.

<Directory “/var/www/html”>

Possible values for the Options directive are “None”, “All”,

or any combination of:

Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI

MultiViews

Note that “MultiViews” must be named explicitly — “Options All”

doesn’t give it to you.

The Options directive is both complicated and important. Please see

http://httpd.apache.org/docs/2.2/mod/core.html#options

for more information.

Options Indexes FollowSymLinks

AllowOverride controls what directives may be placed in .htaccess

files.

It can be “All”, “None”, or any combination of the keywords:

Options FileInfo AuthConfig Limit

AllowOverride None

Controls who can get stuff from this server.

Order allow,deny
Allow from all

UserDir: The name of the directory that is appended onto a user’s home

directory if a ~user request is received.

The path to the end user account ‘public_html’ directory must be

accessible to the webserver userid. This usually means that ~userid

must have permissions of 711, ~userid/public_html must have

permissions

of 755, and documents contained therein must be world-readable.

Otherwise, the client will only receive a “403 Forbidden” message.

See also: http://httpd.apache.org/docs/misc/FAQ.html#forbidden

# # UserDir is disabled by default since it can confirm the presence # of a username on the system (depending on home directory # permissions). # UserDir disable
#
# To enable requests to /~user/ to serve the user's public_html
# directory, remove the "UserDir disable" line above, and uncomment
# the following line instead:
#
#UserDir public_html

Control access to UserDir directories. The following is an example

for a site where these directories are restricted to read-only.

#<Directory /home/*/public_html>

AllowOverride FileInfo AuthConfig Limit

Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec

Order allow,deny

Allow from all

Order deny,allow

Deny from all

#

DirectoryIndex: sets the file that Apache will serve if a directory

is requested.

The index.html.var file (a type-map) is used to deliver content-

negotiated documents. The MultiViews Option can be used for the

same purpose, but it is much slower.

DirectoryIndex index.html index.html.var

AccessFileName: The name of the file to look for in each directory

for additional configuration directives. See also the AllowOverride

directive.

AccessFileName .htaccess

The following lines prevent .htaccess and .htpasswd files from being

viewed by Web clients.

<Files ~ “^.ht”>
Order allow,deny
Deny from all

TypesConfig describes where the mime.types file (or equivalent) is

to be found.

TypesConfig /etc/mime.types

DefaultType is the default MIME type the server will use for a

document

if it cannot otherwise determine one, such as from filename

extensions.

If your server contains mostly text or HTML documents, “text/plain” is

a good value. If most of your content is binary, such as applications

or images, you may want to use “application/octet-stream” instead to

keep browsers from trying to display binary files as though they are

text.

DefaultType text/plain

The mod_mime_magic module allows the server to use various hints from

the

contents of the file itself to determine its type. The MIMEMagicFile

directive tells the module where the hint definitions are located.

# MIMEMagicFile /usr/share/magic.mime MIMEMagicFile conf/magic

HostnameLookups: Log the names of clients or just their IP addresses

e.g., www.apache.org (on) or 204.62.129.132 (off).

The default is off because it’d be overall better for the net if

people

had to knowingly turn this feature on, since enabling it means that

each client request will result in AT LEAST one lookup request to the

nameserver.

HostnameLookups Off

EnableMMAP: Control whether memory-mapping is used to deliver

files (assuming that the underlying OS supports it).

The default is on; turn this off if you serve from NFS-mounted

filesystems. On some systems, turning it off (regardless of

filesystem) can improve performance; for details, please see

http://httpd.apache.org/docs/2.2/mod/core.html#enablemmap

#EnableMMAP off

EnableSendfile: Control whether the sendfile kernel support is

used to deliver files (assuming that the OS supports it).

The default is on; turn this off if you serve from NFS-mounted

filesystems. Please see

http://httpd.apache.org/docs/2.2/mod/core.html#enablesendfile

#EnableSendfile off

ErrorLog: The location of the error log file.

If you do not specify an ErrorLog directive within a

container, error messages relating to that virtual host will be

logged here. If you do define an error logfile for a

container, that host’s errors will be logged there and not here.

ErrorLog logs/error_log

LogLevel: Control the number of messages logged to the error_log.

Possible values include: debug, info, notice, warn, error, crit,

alert, emerg.

LogLevel warn

The following directives define some format nicknames for use with

a CustomLog directive (see below).

LogFormat “%h %l %u %t “%r” %>s %b “%{Referer}i” “%{User-Agent}i””
combined
LogFormat “%h %l %u %t “%r” %>s %b” common
LogFormat “%{Referer}i -> %U” referer
LogFormat “%{User-agent}i” agent

“combinedio” includes actual counts of actual bytes received (%I) and

sent (%O); this

requires the mod_logio module to be loaded.

#LogFormat “%h %l %u %t “%r” %>s %b “%{Referer}i” “%{User-Agent}i”
%I %O” combinedio

The location and format of the access logfile (Common Logfile Format).

If you do not define any access logfiles within a

container, they will be logged here. Contrariwise, if you do

define per- access logfiles, transactions will be

logged therein and not in this file.

#CustomLog logs/access_log common

If you would like to have separate agent and referer logfiles,

uncomment

the following directives.

#CustomLog logs/referer_log referer
#CustomLog logs/agent_log agent

For a single logfile with access, agent, and referer information

(Combined Logfile Format), use the following directive:

CustomLog logs/access_log combined

Optionally add a line containing the server version and virtual host

name to server-generated pages (internal error documents, FTP

directory

listings, mod_status and mod_info output etc., but not CGI generated

documents or custom error documents).

Set to “EMail” to also include a mailto: link to the ServerAdmin.

Set to one of: On | Off | EMail

ServerSignature On

Aliases: Add here as many aliases as you need (with no limit). The

format is

Alias fakename realname

Note that if you include a trailing / on fakename then the server will

require it to be present in the URL. So “/icons” isn’t aliased in

this

example, only “/icons/”. If the fakename is slash-terminated, then

the

realname must also be slash terminated, and if the fakename omits the

trailing slash, the realname must also omit it.

We include the /icons/ alias for FancyIndexed directory listings. If

you

do not use FancyIndexing, you may comment this out.

Alias /icons/ “/var/www/icons/”

<Directory “/var/www/icons”>
Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from all

WebDAV module configuration section.

# Location of the WebDAV lock database. DAVLockDB /var/lib/dav/lockdb

ScriptAlias: This controls which directories contain server scripts.

ScriptAliases are essentially the same as Aliases, except that

documents in the realname directory are treated as applications and

run by the server when requested rather than as documents sent to the

client.

The same rules about trailing “/” apply to ScriptAlias directives as

to

Alias.

ScriptAlias /cgi-bin/ “/var/www/cgi-bin/”

“/var/www/cgi-bin” should be changed to whatever your ScriptAliased

CGI directory exists, if you have that configured.

<Directory “/var/www/cgi-bin”>
AllowOverride None
Options None
Order allow,deny
Allow from all

Redirect allows you to tell clients about documents which used to

exist in

your server’s namespace, but do not anymore. This allows you to tell

the

clients where to look for the relocated document.

Example:

Redirect permanent /foo http://www.example.com/bar

Directives controlling the display of server-generated directory

listings.

IndexOptions: Controls the appearance of server-generated directory

listings.

IndexOptions FancyIndexing VersionSort NameWidth=* HTMLTable

AddIcon* directives tell the server which icon to show for different

files or filename extensions. These are only displayed for

FancyIndexed directories.

AddIconByEncoding (CMP,/icons/compressed.gif) x-compress x-gzip

AddIconByType (TXT,/icons/text.gif) text/*

DefaultIcon is which icon to show for files which do not have an icon

explicitly set.

DefaultIcon /icons/unknown.gif

AddDescription allows you to place a short description after a file in

server-generated indexes. These are only displayed for FancyIndexed

directories.

Format: AddDescription “description” filename

#AddDescription “GZIP compressed document” .gz
#AddDescription “tar archive” .tar
#AddDescription “GZIP compressed tar archive” .tgz

ReadmeName is the name of the README file the server will look for by

default, and append to directory listings.

HeaderName is the name of a file which should be prepended to

directory indexes.

ReadmeName README.html
HeaderName HEADER.html

IndexIgnore is a set of filenames which directory indexing should

ignore

and not include in the listing. Shell-style wildcarding is permitted.

IndexIgnore .??* ~ # HEADER README RCS CVS *,v *,t

DefaultLanguage and AddLanguage allows you to specify the language of

a document. You can then use content negotiation to give a browser a

file in a language the user can understand.

Specify a default language. This means that all data

going out without a specific language tag (see below) will

be marked with this one. You probably do NOT want to set

this unless you are sure it is correct for all cases.

* It is generally better to not mark a page as

* being a certain language than marking it with the wrong

* language!

DefaultLanguage nl

Note 1: The suffix does not have to be the same as the language

keyword — those with documents in Polish (whose net-standard

language code is pl) may wish to use “AddLanguage pl .po” to

avoid the ambiguity with the common suffix for perl scripts.

Note 2: The example entries below illustrate that in some cases

the two character ‘Language’ abbreviation is not identical to

the two character ‘Country’ code for its country,

E.g. ‘Danmark/dk’ versus ‘Danish/da’.

Note 3: In the case of ‘ltz’ we violate the RFC by using a three char

specifier. There is ‘work in progress’ to fix this and get

the reference data for rfc1766 cleaned up.

LanguagePriority allows you to give precedence to some languages

in case of a tie during content negotiation.

Just list the languages in decreasing order of preference. We have

more or less alphabetized them here. You probably want to change this.

LanguagePriority en ca cs da de el eo es et fr he hr it ja ko ltz nl nn
no pl pt pt-BR ru sv zh-CN zh-TW

ForceLanguagePriority allows you to serve a result page rather than

MULTIPLE CHOICES (Prefer) [in case of a tie] or NOT ACCEPTABLE

(Fallback)

[in case no accepted languages matched the available variants]

ForceLanguagePriority Prefer Fallback

Specify a default charset for all content served; this enables

interpretation of all content as UTF-8 by default. To use the

default browser choice (ISO-8859-1), or to allow the META tags

in HTML content to override this choice, comment out this

directive:

AddDefaultCharset UTF-8

AddType allows you to add to or override the MIME configuration

file mime.types for specific file types.

#AddType application/x-tar .tgz

AddEncoding allows you to have certain browsers uncompress

information on the fly. Note: Not all browsers support this.

Despite the name similarity, the following Add* directives have

nothing

to do with the FancyIndexing customization directives above.

#AddEncoding x-compress .Z
#AddEncoding x-gzip .gz .tgz

If the AddEncoding directives above are commented-out, then you

probably should define those extensions to indicate media types:

AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz

AddHandler allows you to map certain file extensions to “handlers”:

actions unrelated to filetype. These can be either built into the

server

or added with the Action directive (see below)

To use CGI scripts outside of ScriptAliased directories:

(You will also need to add “ExecCGI” to the “Options” directive.)

#AddHandler cgi-script .cgi

For files that include their own HTTP headers:

#AddHandler send-as-is asis

For type maps (negotiated resources):

(This is enabled by default to allow the Apache “It Worked” page

to be distributed in multiple languages.)

AddHandler type-map var

Filters allow you to process content before it is sent to the client.

To parse .shtml files for server-side includes (SSI):

(You will also need to add “Includes” to the “Options” directive.)

AddType text/html .shtml
AddOutputFilter INCLUDES .shtml

Action lets you define media types that will execute a script whenever

a matching file is called. This eliminates the need for repeated URL

pathnames for oft-used CGI file processors.

Format: Action media/type /cgi-script/location

Format: Action handler-name /cgi-script/location

Customizable error responses come in three flavors:

1) plain text 2) local redirects 3) external redirects

Some examples:

#ErrorDocument 500 “The server made a boo boo.”
#ErrorDocument 404 /missing.html
#ErrorDocument 404 “/cgi-bin/missing_handler.pl”
#ErrorDocument 402 http://www.example.com/subscription_info.html

Putting this all together, we can internationalize error responses.

We use Alias to redirect any /error/HTTP_.html.var response to

our collection of by-error message multi-language collections. We use

includes to substitute the appropriate text.

You can modify the messages’ appearance without changing any of the

default HTTP_.html.var files by adding the line:

Alias /error/include/ “/your/include/path/”

which allows you to create your own set of files by starting with the

/var/www/error/include/ files and

copying them to /your/include/path/, even on a per-VirtualHost basis.

Alias /error/ “/var/www/error/”

The following directives modify normal HTTP response behavior to

handle known problems with browser implementations.

BrowserMatch “Mozilla/2” nokeepalive
BrowserMatch “MSIE 4.0b2;” nokeepalive downgrade-1.0 force-response-1.0
BrowserMatch “RealPlayer 4.0” force-response-1.0
BrowserMatch “Java/1.0” force-response-1.0
BrowserMatch “JDK/1.0” force-response-1.0

The following directive disables redirects on non-GET requests for

a directory that does not include the trailing slash. This fixes a

problem with Microsoft WebFolders which does not appropriately handle

redirects for folders with DAV methods.

Same deal with Apple’s DAV filesystem and Gnome VFS support for DAV.

BrowserMatch “Microsoft Data Access Internet Publishing Provider”
redirect-carefully
BrowserMatch “MS FrontPage” redirect-carefully
BrowserMatch “^WebDrive” redirect-carefully
BrowserMatch “^WebDAVFS/1.[0123]” redirect-carefully
BrowserMatch “^gnome-vfs/1.0” redirect-carefully
BrowserMatch “^XML Spy” redirect-carefully
BrowserMatch “^Dreamweaver-WebDAV-SCM1” redirect-carefully

Section 3: Virtual Hosts

VirtualHost: If you want to maintain multiple domains/hostnames on

your

machine you can setup VirtualHost containers for them. Most

configurations

use only name-based virtual hosts so the server doesn’t need to worry

about

IP addresses. This is indicated by the asterisks in the directives

below.

Please see the documentation at

URL:http://httpd.apache.org/docs/2.2/vhosts/

for further details before you try to setup virtual hosts.

You may use the command line option ‘-S’ to verify your virtual host

configuration.

Use name-based virtual hosting.

#NameVirtualHost *:80

NOTE: NameVirtualHost cannot be used without a port specifier

(e.g. :80) if mod_ssl is being used, due to the nature of the

SSL protocol.

VirtualHost example:

Almost any Apache directive may go into a VirtualHost container.

The first VirtualHost section is used for requests without a known

server name.

#<VirtualHost *:80>

ServerAdmin [email protected]

DocumentRoot /www/docs/dummy-host.example.com

ServerName dummy-host.example.com

ErrorLog logs/dummy-host.example.com-error_log

CustomLog logs/dummy-host.example.com-access_log common

#

I am basing my configurations loosely off
