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
