Following is an automated script to install SQUID 2.7 Stable 9 for UBUNTU with aggressive contents & few video web sites video caching support as described in my other article @
http://aacable.wordpress.com/2012/01/19/youtube-caching-with-squid-2-7-using-storeurl-pl/
I will add more n more functions as soon as I get some free time, like configurable options via choice menu like cache size, mem, and other variables.
▼
SCRIPT FUNCTIONS . . .
This script will do the following
- First it will ask you if you want 32bit or 64 squid compile options
- Update Ubuntu
- Install some components required for Compilation of squid package
- Backup squid.conf if already in /etc/squid.conf with squid.conf.old, stop any running squid instance
- Download Squid 2.7 stable 9 source package to /temp folder and compile it
- Download squid.conf and storeurl.pl from the internet and place them in /etc/squid.conf
- Create cache directory like in /cache-1 and default cache size is 10 GB
- add squid in /etc/rc.local so it may start auto upon system reboot [added: 5th January, 2014]
- removed few bugs including “unable to start squid” error in end, while actually squid is running [added: 6th January, 2014 9:20AM]
You should Modify all options like cache_dir, cache_mem and others as per your requirements.
