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

ProxyPassReverse / balancer://depot_cluster/

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

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

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 root@localhost
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
core - Apache HTTP Server Version 2.2
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
core - Apache HTTP Server Version 2.2
#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
core - Apache HTTP Server Version 2.2
#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.

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
