Tutorial – Installing Squid 2.7 in Debian VPS

This time, I’m gonna write a tutorial for installing squid proxy in a Debian VPS ( BuyVM )

• Lets install squid in the Debian VPS :
  
  # apt-get install squid

  1	# apt-get install squid

• Shutdown squid if it’s running :
  
  # squid -k shutdown or # service squid stop

  1 2 3

  # squid -k shutdown or # service squid stop

• Configure the squid.conf located at /etc/squid/squid.conf:
  
  # nano /etc/squid/squid.conf

  1	# nano /etc/squid/squid.conf

  
  Add the following code at the top of squid.conf :
  
  auth_param basic program /usr/lib/squid/pam_auth auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 4 hours acl password proxy_auth REQUIRED http_access allow password forwarded_for off auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/users_passwd acl ncsa_users proxy_auth REQUIRED http_access allow ncsa_users

  1 2 3 4 5 6 7 8 9 10

  auth_param basic program /usr/lib/squid/pam_auth auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 4 hours acl password proxy_auth REQUIRED http_access allow password forwarded_for off auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/users_passwd acl ncsa_users proxy_auth REQUIRED http_access allow ncsa_users

  
  To change the squid port from default port 3128 to another port, reopen again the /etc/squid/squid.conf, change the http_port from 3128 to another port to secure your squid from unauthorized use, for example :
  
  http_port 12873

  1	http_port 12873

  
  Save the modified squid.conf  by pressing Ctrl + O, and press Enter
  Exit from nano editor by pressing Ctrl + X
• Create file users_password for squid security purpose :
  
  # nano /etc/squid/users_passwd

  1	# nano /etc/squid/users_passwd

  
  Type a character and delete it. And then save the file by pressing Ctrl + O
  Exit from the nano editor by pressing Ctrl + X
• Now, we will use the function htpasswd from the apache to securing access to our squid server :
  
  # htpasswd /etc/squid/users_passwd user-for-accessing-squid

  1	# htpasswd /etc/squid/users_passwd user-for-accessing-squid

  
  for example :
  
  # htpasswd /etc/squid/users_passwd userssatu

  1	# htpasswd /etc/squid/users_passwd userssatu

  
  Type the password for it.
• Running the squid :
  
  # service squid start

  1	# service squid start

• Now you have a squid program running in your Debian VPS.

If you want to use it, you can use the example configuration at your browser proxy setting :
IP Address : 123.123.123.123  Port : 12873
The IP Address is your VPS IP Address, and the Port is using your squid http_port configuration
