Step 3: Enable and start the services by using the below command
[root@linuxhelp ~]# systemctl enable squid.service
Created symlink /etc/systemd/system/multi-user.target.wants/squid.service → /usr/lib/systemd/system/squid.service.
[root@linuxhelp ~]# systemctl start squid.service
Step 4: Check the status of squid server by using the below command
[root@linuxhelp ~]# systemctl status squid.service

├─40143 (squid-1) --kid squid-1 --foreground -f /etc/squid/squid.conf
└─40144 (logfile-daemon) /var/log/squid/access.log
Step 5: Configure the rule for access domain by using the below command
[root@linuxhelp ~]# vim /etc/squid/squid.conf
# Example rule allowing access from your local networks.
acl facebook.com src 192.168.6.122/23 #your facebook.com internal network
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTSacl surfing_hours time M T W H F 17:54-17:55
http_access allow facebook.com surfing_hours
http_access deny facebook.com
Step 6: Restart squid service by using the below command
[root@linuxhelp ~]# systemctl restart squid.service
Step 7: Go to browser settings and search proxy as shown in the below image
Step 8: Enter the proxy server ip and port number in manual proxy configuration under configure proxy access to the internet as shown in the below image
Step 9: searching facebook.com time 17:53 as shown in the below image
Step 10: Search facebook.com time 17:54 now it will be accessible as shown in the below image
Step 11: Search facebook.com time 17:56 now it is refusing by proxy server as shown in the below image
