How to run jenkins as a different user

I have been trying to follow tutorials and this one: Deploy as Jenkins User or Allow Jenkins To Run As Different User?

but I still can't for the love of the computing gods, run as a different user. Here are the steps of what I did:

1. download the macosx pkg for jenkins(LTS)
2. setup plugins etc and git
3. try to build it

I keep getting a can't clone error because jenkins keeps starting as anonymous:

Started by user anonymous

How do I set it up so that jenkins runs as me? I was using the jenkins web UI so it was in localhost:8080

I tried logging in also using /login but I can't开发者_运维知识库 even login using my name or as root.

The people tab doesn't even have a create user link, so yeah I've been stuck. Help please?

The "Issue 2" answer given by @Sagar works for the majority of git servers such as gitorious.

However, there will be a name clash in a system like gitolite where the public ssh keys are checked in as files named with the username, ie keydir/jenkins.pub. What if there are multiple jenkins servers that need to access the same gitolite server?

(Note: this is about running the Jenkins daemon not running a build job as a user (addressed by @Sagar's "Issue 1").)

So in this case you do need to run the Jenkins daemon as a different user.

There are two steps:

Step 1

The main thing is to update the JENKINS_USER environment variable. Here's a patch showing how to change the user to ptran.

Step 2

Update ownership of jenkins directories:

chown -R ptran /var/log/jenkins
chown -R ptran /var/lib/jenkins
chown -R ptran /var/run/jenkins
chown -R ptran /var/cache/jenkins

Step 3

Restart jenkins

sudo service jenkins restart

ISSUE 1:

Started by user anonymous

That does not mean that Jenkins started as an anonymous user.

It just means that the person who started the build was not logged in. If you enable Jenkins security, you can create usernames for people and when they log in, the

"Started by anonymous" 

will change to

"Started by < username >". 

Note: You do not have to enable security in order to run jenkins or to clone correctly.

If you want to enable security and create users, you should see the options at Manage Jenkins > Configure System.

---

ISSUE 2:

The "can't clone" error is a different issue altogether. It has nothing to do with you logging in to jenkins or enabling security. It just means that Jenkins does not have the credentials to clone from your git SCM.

Check out the Jenkins Git Plugin to see how to set up Jenkins to work with your git repository.

Hope that helps.

On Mac OS X, the way I enabled Jenkins to pull from my (private) Github repo is:

First, ensure that your user owns the Jenkins directory

sudo chown -R me:me /Users/Shared/Jenkins

Then edit the LaunchDaemon plist for Jenkins (at /Library/LaunchDaemons/org.jenkins-ci.plist) so that your user is the GroupName and the UserName:

    <key>GroupName</key>
    <string>me</string>
...
    <key>UserName</key>
    <string>me</string>

Then reload Jenkins:

sudo launchctl unload -w /Library/LaunchDaemons/org.jenkins-ci.plist
sudo launchctl load -w /Library/LaunchDaemons/org.jenkins-ci.plist

Then Jenkins, since it's running as you, has access to your ~/.ssh directory which has your keys.

If you really want to run Jenkins as you, I suggest you check out my Jenkins.app. An alternative, easy way to run Jenkins on Mac.

To run jenkins as different user on ubuntu os you need to change below things.

Update below two lines in /etc/default/jenkins file

JENKINS_USER=$USERNAME

JENKINS_GROUP=$NAME

In our case we set user as ubuntu.

#JENKINS_USER=$NAME
#JENKINS_GROUP=$NAME
JENKINS_USER="ubuntu"
JENKINS_GROUP="ubuntu"

Update below two lines in /lib/systemd/system/jenkins.service file

User=jenkins

Group=jenkins

In our case we set user as ubuntu.

#User=jenkins
#Group=jenkins
User=ubuntu
Group=ubuntu

Change file ownership of jenkins owned folders.

sudo chown -R ubuntu:ubuntu /var/lib/jenkins
sudo chown -R ubuntu:ubuntu /var/cache/jenkins
sudo chown -R ubuntu:ubuntu /var/log/jenkins

After above changes run below command to reload systemctl

sudo systemctl daemon-reload

Now you can restart jenkins

sudo systemctl restart jenkins.service

you can integrate to LDAP or AD as well. It works well.
