Пункт 59. Using Apache With RPM Based Systems
While many distributions make Apache httpd available as operating system
supported packages, it can sometimes be desirable to install and use the
canonical version of Apache httpd on these systems, replacing the natively
provided versions of the packages.
While the Apache httpd project does not currently create binary RPMs
for the various distributions out there, it is easy to build your own
binary RPMs from the canonical Apache httpd tarball.
This document explains how to build, install, configure and run
Apache httpd 2.4 under Unix systems supporting the RPM packaging format.
Creating a Source RPM
The Apache httpd source tarball can be converted into an SRPM as
follows:
rpmbuild -ts httpd-2.4.x.tar.bz2
Building RPMs
RPMs can be built directly from the Apache httpd source tarballs using
the following command:
rpmbuild -tb httpd-2.4.x.tar.bz2
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:
rpm -U httpd-2.4.x-1.i686.rpm
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:
service httpd restart
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.
