When you install Jenkins, by default the Jenkins service runs on port 8080. Also, there is no direct option to run Jenkins on port 80.<\/p>\n
In this tutorial, we have explained the steps to setup Jenkins access on port 80.<\/p>\n
You can run Jenkins on port 80 using the following methods.<\/p>\n
We will explain all three methods. You can choose one which is suitable for your environment.<\/p>\n
This is the easiest way to access Jenkins on port 80. All you have to do is run the following IPtables<\/a> fording rule.<\/p>\n Now, you should save these rules to persist even after an IPtable or a system restart.<\/p>\n For Redhat-based systems, run the following.<\/p>\n For Ubuntu-based Jenkins<\/a>, execute the following command.<\/p>\n Now if you access Jenkins on port 80, IP table will automatically forward the requests to 8080.<\/p>\n If you setting up a production Jenkins server, you can consider the Nginx reverse proxy option.<\/p>\n Nginx is very lightweight and it can act as the best reverse proxy for Jenkins. Follow the steps given below to run Jenkins behind an Nginx reverse proxy.<\/p>\n Step1:<\/strong> Install Nginx<\/p>\n Step 2:<\/strong> Open the Nginx configuration file.<\/p>\n Step 3: <\/strong>Find the following snippet in the nginx.conf file.<\/p>\n Step 4:<\/strong> Add the following lines between the curly braces.<\/p>\n Step 5:<\/strong> Execute the SELinux command for the Nginx reverse proxy.<\/p>\n Step 6:<\/strong> Restart the Nginx server.<\/p>\n Now if you will be able to access Jenkins on port 80.<\/p>\n Adding a load balancer will add extra cost to the Jenkins setup.<\/p>\n If you are on a cloud, you can opt for a cloud-specific load balancer that will send all its port 80 traffic to the backend Jenkins 8080 port.<\/p>\n If you are running Jenkins on kubernetes<\/a>, you can use the ingress rules to forward port 80 to Jenkins kubernetes service endpoint.<\/p>\n Additionally, you can use the HTTPS ingress option if you want SSL for Jenkins<\/a>.<\/p>\nsudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080<\/code><\/pre>\nsudo iptables-save > \/etc\/sysconfig\/iptables<\/code><\/pre>\nsudo sh -c \"iptables-save > \/etc\/iptables.rules\"<\/code><\/pre>\nRunning Jenkins Behind Nginx Reverse Proxy<\/h2>\n
