Common Mistakes

Using port 80 which requires root privileges

💡 Hint

Common Mistakes

Using file system paths instead of URL paths for --prefix

Confusing home directory with URL prefix

The --prefix option sets the URL prefix, not the home directory. To set the home directory, use the environment variable JENKINS_HOME. Use /custom_home as a URL prefix example.

💡 Hint

Common Mistakes

Using URL paths for home directory

Using default port instead of 8085

Omitting the prefix or using wrong format

Set the environment variable JENKINS_HOME to /var/lib/jenkins to specify the Jenkins home directory. Run Jenkins on port 8085 with the prefix URL /ci.
