centos7 web Proxy

CentOS 7 is a popular Linux distribution that can be used as a web proxy server. To set up a web proxy on CentOS 7, you can follow these steps:

1. Install CentOS 7: Download the CentOS 7 ISO file and install it on your server.
2. Update system packages: Open a terminal and run the following command to update the system packages:

   sudo yum update

3. Install Squid: Squid is a widely used open-source proxy server. Install it by running the following command:

   sudo yum install squid

4. Configure Squid: Open the Squid configuration file using a text editor:

   sudo nano /etc/squid/squid.conf

Customize the Squid configuration based on your requirements. You can specify access control rules, define ACLs (Access Control Lists), set cache settings, etc. Refer to the Squid documentation for detailed configuration options.

5. Start and enable Squid: Start Squid and enable it to start automatically on system boot:

   sudo systemctl start squid
   sudo systemctl enable squid

6. Configure firewall: If you have a firewall enabled, make sure to allow incoming connections to Squid. You can use the following commands to open the necessary ports:

   sudo firewall-cmd --add-service=squid --permanent
   sudo firewall-cmd --reload

7. Test the proxy: You can now test your web proxy by configuring your web browser or other applications to use the proxy server's IP address and port number.

Remember to adjust the Squid configuration and firewall settings based on your specific setup and security requirements.
