<p>Created page with &quot;==How to Install Squid Proxy Server on Cento7== This will be running on a CENTOS/RHEL 7 VM with minimum specs. ===I set these up on cheap vps like === # https://www.vultr.com...&quot;</p> <p><b>New page</b></p><div>==How to Install Squid Proxy Server on Cento7==<br /> <br /> This will be running on a CENTOS/RHEL 7 VM with minimum specs.<br /> ===I set these up on cheap vps like ===<br /> # https://www.vultr.com/<br /> # https://www.digitalocean.com/<br /> # https://www.linode.com/<br /> # https://www.thermo.io/<br /> <br /> ===Install Squid Server===<br /> This will be running on a CENTOS/RHEL 7 VM with minimum specs.<br /> <br /> Make sure to have your server up-to-date by running<br /> <br /> yum -y update<br /> <br /> Next, we need to install Squid Proxy by running the following command:<br /> <br /> yum -y install squid<br /> <br /> Once your Squid has been successfully installed you can go ahead and start the program immediately<br /> <br /> systemctl start squid<br /> <br /> Do not forget to enable the squid service in order to start automatically at boot.<br /> <br /> systemctl enable squid<br /> <br /> It is important to check on the Squid status just to make sure that everything is working fine.<br /> <br /> systemctl status squid<br /> <br /> You should get dialog with a saying its running..<br /> <br /> ===Configure Squid to Allow your IP===<br /> <br /> You will need to edit the configuration file and add your connecting ips or ranges.<br /> <br /> vi /etc/squid/squid.conf<br /> <br /> How to allow a range of IP addresses to access the Internet through your proxy server<br /> <br /> It is just as simple as adding a new ACL entry, Squid supports CIDR notation which makes the job more simple, for example, if you want to allow a range of IPs from 192.168.241.1 to 192.168.241.255 then you will need to add the following entry:<br /> <br /> Find the line that starts with # should be allowed and add your ip/range below that.<br /> <br /> acl localnet src 192.168.241.0/24 # My new ACL<br /> Or your work IP <br /> acl localnet src 75.12.56.124 #Work IP<br /> <br /> Last but not least restart squid to make the change active.<br /> <br /> systemctl restart squid<br /> <br /> ===Change Squid Default Port===<br /> <br /> If you feel the need of changing the Squid default port, you just need to modify:<br /> <br /> vi /etc/squid/squid.conf<br /> <br /> Then find the following line and change the port<br /> <br /> Squid normally listens to port 3128<br /> http_port 3128<br /> <br /> Change to that your next favorite number<br /> <br /> http_port 1337<br /> <br /> ===Allowing access in firewalld===<br /> <br /> firewall-cmd --permanent --add-port=1337/tcp<br /> firewall-cmd --reload<br /> <br /> There is nothing else to say at this moment if you need to go a little bit more in deep about Squid go and check out their website http://www.squid-cache.org/ their documentation is pretty good.<br /> <br /> Hope you enjoyed this tutorial and do not forget to share it.</div>
