Installation And Configuration

# yum install -y squid
# vim /etc/squid/squid.conf
http_port 3072
#acl localnet src        # RFC1918 possible internal network
# Squid normally listens to port 3128
http_port 3072
cache_mem 64 MB
maximum_object_size 4 MB
# Cache 3GB
cache_dir ufs /home/juju/SquidCache     3072    16      256
access_log /var/log/squid/access.log
auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/passwd
auth_param basic children 5
auth_param basic kspc-01 proxy
auth_param basic credentialsttl 2 hours
acl myacl proxy_auth REQUIRED
http_access allow myacl
http_access deny all
visible_hostname squid.kspc-01

First you should setup the cache file:

# squid -z
# systemctl start squid
# systemctl enable squid

Change username password via:

$ htpasswd -c /etc/squid/passwd user1
$ htpasswd  /etc/squid/passwd user2
$ htpasswd  /etc/squid/passwd user3


In firefox: Edit->Preference->Network->Settings->, change proxy setting.


Just comment following lines in /etc/squid/squid.conf, you could get non-auth squid setup:

http_access allow all
#auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/passwd
#auth_param basic children 5
#auth_param basic kspc-01 proxy
#auth_param basic credentialsttl 2 hours
#acl myacl proxy_auth REQUIRED
#http_access allow myacl
#http_access deny all

Use proxy for yum

Add following lines in /etc/yum.conf:

$ echo "proxy=">>/etc/yum.conf
