Getting Apache error when trying to load mod_ruby

Hi,

I’m using Apache 2.2 on Fedora Core 6 Linux. I’m using ruby 1.8.6 and
mod_ruby 1.2.5. I get this error when starting Apache:

[Wed Jan 16 09:40:26 2008] [error] mod_ruby: failed to require apache/
ruby-run
[Wed Jan 16 09:40:26 2008] [error] mod_ruby: error in ruby
[Wed Jan 16 09:40:26 2008] [error] mod_ruby: ruby:0:in `require’: no
such file to load – apache/ruby-run (LoadError)

Does anyone know what could be causing this? I’m including my
httpd.conf file if that is useful:

==================Begin httpd.conf file========================

This is the main Apache HTTP 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.

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 “/usr/local/apache2” will be interpreted by

the

server as “/usr/local/apache2/logs/foo.log”.

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

configuration, error, and log files are kept.

Do not add a slash at the end of the directory path. If you point

ServerRoot at a non-local disk, be sure to point the LockFile

directive

at a local disk. If you wish to share the same ServerRoot for

multiple

httpd daemons, you will need to change at least LockFile and

PidFile.

ServerRoot “/usr/local/apache2”

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

ports, instead of 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.

#Listen 12.34.56.78:80
Listen 80
Listen 443

ServerName http://remandev.no-ip.org
SSLEngine on
SSLCertificateFile /usr/local/apache2/ssl/remandev.no-ip.org.cert
SSLCertificateKeyFile /usr/local/apache2/ssl/remandev.no-ip.org.key

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 php4_module modules/libphp4.so

  AddType application/x-httpd-php .php .phtml
  AddType application/x-httpd-php-source .phps

Allow for ssl

#LoadModule ssl_module modules/libmodssl.so

<IfModule !mpm_netware_module>

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.

It is usually good practice to create a dedicated user and group for

running httpd, as with most system services.

User daemon
Group daemon

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

address here.

#ServerName www.example.com:80

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 “/usr/local/apache2/htdocs”

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 Order deny,allow Deny from all

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 “/usr/local/apache2/htdocs”>
#
# 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

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

is requested.

DirectoryIndex index.html

The following lines prevent .htaccess and .htpasswd files from

being

viewed by Web clients.

<FilesMatch “^.ht”>
Order allow,deny
Deny from all
Satisfy All

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
<IfModule logio_module>
  # You need to enable mod_logio.c to use %I and %O
  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 prefer a logfile with access, agent, and referer

information
# (Combined Logfile Format) you can use the following directive.
#
#CustomLog logs/access_log combined

# # Redirect: Allows you to tell clients about documents that used to # exist in your server's namespace, but do not anymore. The client # will make a new request for the document at its new location. # Example: # Redirect permanent /foo http://www.example.com/bar
#
# Alias: Maps web paths into filesystem paths and is used to
# access content that does not live under the DocumentRoot.
# Example:
# Alias /webpath /full/filesystem/path
#
# If you include a trailing / on /webpath then the server will
# require it to be present in the URL.  You will also likely
# need to provide a <Directory> section to allow access to
# the filesystem path.

#
# ScriptAlias: This controls which directories contain server

scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the target 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/ “/usr/local/apache2/cgi-bin/”

# # ScriptSock: On threaded servers, designate the path to the UNIX # socket used to communicate with the CGI daemon of mod_cgid. # #Scriptsock logs/cgisock

“/usr/local/apache2/cgi-bin” should be changed to whatever your

ScriptAliased

CGI directory exists, if you have that configured.

<Directory “/usr/local/apache2/cgi-bin”>
AllowOverride None
Options None
Order allow,deny
Allow from all

DefaultType: 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

# # TypesConfig points to the file containing the list of mappings from # filename extension to MIME-type. # TypesConfig conf/mime.types
#
# AddType allows you to add to or override the MIME configuration
# file specified in TypesConfig for specific file types.
#
#AddType application/x-gzip .tgz
#
# AddEncoding allows you to have certain browsers uncompress
# information on the fly. Note: Not all browsers support this.
#
#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 type maps (negotiated resources):
#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

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 conf/magic

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

EnableMMAP and EnableSendfile: On systems that support it,

memory-mapping or the sendfile syscall is used to deliver

files. This usually improves server performance, but must

be turned off when serving from networked-mounted

filesystems or if support for these functions is otherwise

broken on your system.

#EnableMMAP off
#EnableSendfile off

Supplemental configuration

The configuration files in the conf/extra/ directory can be

included to add extra features or to modify the default

configuration of

the server, or you may simply copy their contents here and change

as

necessary.
