Hello, I wanted to use "80" for Jenkins server. and I executed the following:

$ java -jar --httpPort=80 jenkins.war

But It doesn't work. The website is not on. My port 80 is available. Then I have to change it back to 8080.

What might cause this? Thank you.

What OS are you running on? On more recent versions of Windows, you have to enable an application to listen on port 80. Linux requires root to run applications that listen on ports under 1000.

on many systems you need administrative privileges to use a port between
0 to 1024. normally a apache httpd (or nynx) demon runs at this port and
routes to the internal 8080 port.

Hey, I was starting the service with a sudo user. So it should be fine in terms of privilege.

I would think that running Jenkins as the root user would be a very risky.  If one of the users inadvertently defines a Jenkins job that runs the shell command "rm -rf /", your system will self-destruct.

It is best to find another way, rather than running the Jenkins process as the root user.

We run jenkins on tomcat on port 8080 but then use iptables to route port 80 to 8080.  Works great.  Here is one sample:
