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
Usage
In firefox: Edit->Preference->Network->Settings->, change proxy setting.
Non-Auth
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=http://192.168.1.79:3128">>/etc/yum.conf
