c)Configuring Squid

 

With default configuration of squid installation, squid is installed in /usr/local/squid/ directory. Before starting squid, we have to change configuration file and ownership.

 

i)                     Check squid user availability

 

# id squid

 

Has to return user information with group details.

 

If you find Cann't find user squid then,

 

# groupadd squid

# useruser -G squid squid

 

ii)                   Editing squid configuration file (squid.conf) for Proxy Mode

 

Get your machine hostname or Fully Qualified Domain Name as,

 

# hostname

 

Open /usr/local/squid/etc/squid.conf with vi editor or view or vim as,

 

# vi /usr/local/squid/etc/squid.conf

Turn vi editor to Insert mode by pressing "i" character on keyboard

 

visible_hostname "your hostname"

cache_effective_user squid

cache_effetive_group squid

 

iii)   Changing directory permission

 

Change /usr/local/squid/var/ directory with permission to squid:squid as,

 

# chown -R squid:squid /usr/local/squid/var

d)      Creating swap directories and starting Squid

 

During first time startup of squid, you have to create swap directories as,

 

# /usr/local/squid/sbin/squid -z

 

Pls Note: If you get any problem during swap directories creation, act based upon the input given. If you could not solve it, please send your queries likedreaminator@gmail.com

 

Start squid in non-deamon and debug mode as,

 

# /usr/local/squid/sbin/squid -NCd10

 

If you get "Ready to server Requests" message then our squid installation is successful.

 

Troubleshooting Note:

 

Sometimes you may find problem to start squid because of DNS server resolvation, then you can start it by disabling INTERNAL DNS lookup as,

 

# /usr/local/squid/sbin/squid -NCd10 -D


e)Starting Squid in Daemon Mode

 

Start squid in daemon as,

 

# /usr/local/squid/sbin/squid
