Apache Installation
If Apache is not currently installed, it is a simple process to install it using yum.
Check Apache Install
To check if Apache is installed, or confirm which version is installed, use the rpm package manager.
[root@shibidp install]# rpm -q httpd
httpd-2.2.3-7.el5.centos
In this case Apache 2.2.3.7 is already installed.
Locate available Apache versions
The yum package manager is the quickest mechanism to locate the versions of Apache available. However it does rely on yum being configured and an internet connection to get the latest yum catalogs.
e.g.
[root@shibidp install]# yum search httpd
returns
httpd-devel.i386 2.2.3-7.el5.centos installed Matched from: httpd-devel The httpd-devel package contains the APXS binary and other files that you need to build Dynamic Shared Objects (DSOs) for the Apache HTTP Server. If you are installing the Apache HTTP server and you want to be able to compile or develop additional modules for Apache, you need to install this package. http://httpd.apache.org/ httpd.i386 2.2.3-7.el5.centos installed Matched from: httpd http://httpd.apache.org/
Installing Apache
If Apache is not installed, you can install it using the following command.
[root@shibidp install]# yum install httpd.i386 2.2.3-7.el5.centos
i.e. take the string from your previous yum search command.
This will install Apache and all dependancies.
The main Apache binary httpd will be installed to /usr/sbin, with the configuration folders set to /etc/httpd. The main web page root will be /var/www
Requirements for the tomcat connector mod_jk
In order to compile the mod_jk connector for Tomcat later, we will need the httpd-devel packages installed. This is done in the same way as the initial Apache install, this will install the apxs libraries required for mod_jk.
[root@shibidp install]# yum install httpd-devel.i386 2.2.3-7.el5.centos
Starting and Stopping Apache.
Once Apache is installed it can be managed using the apachectl command
Start Apache
apachectl start
Stop Apache
apachectl stop
Apache file locations
Executables httpd, apachectl etc /usr/sbin
Configuration files httpd.conf, ssl.conf etc /etc/httpd
Log files error_log, access_log /etc/httpd/log
Web Root document root /var/www/html
