Configure your /etc/rc.d/init.d/squid script file to start and stop the Squid Internet Object Cache. This script has been modified to setup swap cache for Squid in /cache instead of /var/spool/squid. Create the squid script file, touch /etc/rc.d/init.d/squid and add:

               #!/bin/bash
               # squid		This shell script takes care of starting and stopping
               #		Squid Internet Object Cache
               #
               # chkconfig: - 90 25
               # description: Squid - Internet Object Cache. Internet object caching is \
               # 	a way to store requested Internet objects (i.e., data available \
               # 	via the HTTP, FTP, and gopher protocols) on a system closer to the \
               #	requesting site than to the source. Web browsers can then use the \
               #	local Squid cache as a proxy HTTP server, reducing access time as \
               #	well as bandwidth consumption.

Now, make this script executable and change its default permissions:

                 [root@deep /]# chmod 700 /etc/rc.d/init.d/squid
               

Create the symbolic rc.d links for Squid with the command:

                 [root@deep /]# chkconfig --add squid
               

By default the squid script will not automatically start the proxy server on Red Hat Linux when you reboot the server. You can change it's default by executing the following command:

                 [root@deep /]# chkconfig --level 345 squid on
               

Start your new Squid Proxy Server manually with the following command:

                 [root@deep /]# /etc/rc.d/init.d/squid start
               

                 Starting squid: init_cache_dir ufs... squid
