Using Apache With RPM Based Systems (Redhat / CentOS / Fedora)

Creating a Source RPM¶

The Apache httpd source tarball can be converted into an SRPM as follows:

Building RPMs¶

RPMs can be built directly from the Apache httpd source tarballs using the following command:

Corresponding "-devel" packages will be required to be installed on your build system prior to building the RPMs, the rpmbuild command will automatically calculate what RPMs are required and will list any dependencies that are missing on your system. These "-devel" packages will not be required after the build is completed, and can be safely removed.

If successful, the following RPMs will be created:

httpd-2.4.x-1.i686.rpm

The core server and basic module set.

httpd-debuginfo-2.4.x-1.i686.rpm

Debugging symbols for the server and all modules.

httpd-devel-2.4.x-1.i686.rpm

Headers and development files for the server.

httpd-manual-2.4.x-1.i686.rpm

The webserver manual.

httpd-tools-2.4.x-1.i686.rpm

Supporting tools for the webserver.

mod_authnz_ldap-2.4.x-1.i686.rpm

mod_ldap and mod_authnz_ldap, with corresponding dependency on openldap.

mod_lua-2.4.x-1.i686.rpm

mod_lua module, with corresponding dependency on lua.

mod_proxy_html-2.4.x-1.i686.rpm

mod_proxy_html module, with corresponding dependency on libxml2.

mod_socache_dc-2.4.x-1.i686.rpm

mod_socache_dc module, with corresponding dependency on distcache.

mod_ssl-2.4.x-1.i686.rpm

mod_ssl module, with corresponding dependency on openssl.

Installing the Server¶

The httpd RPM is the only RPM necessary to get a basic server to run. Install it as follows:

Self contained modules are included with the server. Modules that depend on external libraries are provided as separate RPMs to install if needed.

Configuring the Default Instance of Apache httpd¶

The default configuration for the server is installed by default beneath the /etc/httpd directory, with logs written by default to /var/log/httpd. The environment for the webserver is set by default within the optional /etc/sysconfig/httpd file.

Start the server as follows:

Configuring Additional Instances of Apache httpd on the Same Machine¶

It is possible to configure additional instances of the Apache httpd server running independently alongside each other on the same machine. These instances can have independent configurations, and can potentially run as separate users if so configured.

This was done by making the httpd startup script aware of its own name. This name is then used to find the environment file for the server, and in turn, the server root of the server instance.

To create an additional instance called httpd-additional, follow these steps:

• Create a symbolic link to the startup script for the additional server:

  ln -s /etc/rc.d/init.d/httpd /etc/rc.d/init.d/httpd-additional
chkconfig --add httpd-additional

• Create an environment file for the server, using the /etc/sysconfig/httpd file as a template:

  # template from httpd
cp /etc/sysconfig/httpd /etc/sysconfig/httpd-additional

  # blank template
touch /etc/sysconfig/httpd-additional

  Edit /etc/sysconfig/httpd-additional and pass the server root of the new server instance within the OPTIONS environment variable.

  OPTIONS="-d /etc/httpd-additional -f conf/httpd-additional.conf"

• Edit the server configuration file /etc/httpd-additional/conf/httpd-additional.conf to ensure the correct ports and paths are configured.
• Start the server as follows:

  service httpd-additional restart

• Repeat this process as required for each server instance.
