Configure Jenkins Proxy with Squid for Domestic Plugin Access

Deploy Squid Network Proxy

Install Squid on the host: $ sudo yum install squid -y Configure Squid by adding an ACL for your local network in /etc/squid/squid.conf: acl localnet src [your address range] Tip: Append the above line under the existing acl localnet src section.

Start Squid and enable it to run at boot: $ sudo systemctl enable squid --now Open the Squid port (3128) in the firewall and reload the rules:

$ sudo firewall-cmd --add-port=3128/tcp --permanent
$ sudo firewall-cmd --reload
$ sudo firewall-cmd --list-port

Tip: Use the above URL as the update site to speed up plugin downloads.

Open Manage Jenkins → Plugins and select the Advanced settings (see images).

Verify the configuration by checking Manage Jenkins → Plugins → Available plugins (see image).

Download and install the Role‑based Authorization Strategy plugin (see images).

Conclusion

By following these steps you can resolve network connectivity and plugin download issues in Jenkins, allowing you to focus on development and innovation. Proper tool configuration is half the battle, and Jenkins remains a powerful ally for automated build, test, and deployment pipelines.
