For Apache Step 1: Install apache2 webserver sudo apt-get update sudo apt-get install apache2 -y [Check the apache installed or not and apache version] apache2 -v [Start the apache service if not running] sudo systemctl start apache2 [Enable apache service at boot time] sudo systemctl enable apache2 [Restart apache service] sudo systemctl restart apache2 Step 2: Create a configuration file under /etc/apache2/sites-availbale [Like I have done in previous Jenkins post] cd /etc/apache2/sites-availbale Step 3: Add the following lines in the jenkins.conf file sudo vim jenkins.conf ServerName jenkins.domain ServerAlias www.jenkins.domain ProxyRequests Off ProxyPass / http://localhost:8080/ ProxyPassReverse / http://localhost:8080/ ProxyPassReverse / http://jenkins.host/...
