Change the 'jenkins' default USER (user_name) on mac - jenkins

I just installed Jenkins on our mac server.
However, looking at the configuration page, it set user.name=jenkins and USER=jenkins
How do I change the 'jenkins' default USER (user_name) on the mac server to something else?
Any help is really appreciated
Thanks

The answer depends on how did you install Jenkins, but I will assume you used the official Jenkins installer for Mac.
As you can see from the launch daemon config file, the username is hard-coded. You will have to change the file, which is installed into your system at /Library/LaunchDaemons/org.jenkins-ci.plist
First, stop Jenkins by running launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist
Change the UserName from "jenkins" to the user you want to use to run Jenkins.
You will need to also change JENKINS_HOME to point to a directory where your preferred user has write permission. (Or change /Users/Shared/Jenkins/Home to be owned by your preferred user.)
Then start Jenkins by running launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist
The next time you upgrade using the Mac installer, your changes will be overwritten, so you will have to do it all over again. It might be safer to stop using the Mac installer and just download the new jenkins.war file and replace it manually.

Better to create new user, it will have all the setup those are configured with old user.
Manage Jenkins > Manage Users > Create User > Provide User Name, Password, Email & all required details
Now login with the new created user name > it will have all the configuration, those were there with old user

unable to login to jenkins.Throwing an error like invalid login information,please try again.Even we entered correct credential

Unable to login to jenkins even if we enter valid credential
You can change the password by manually editing the configuration file for your user. (/jenkins/users/username/config.xml) and update the contents of passwordHash:
<passwordHash>#jbcrypt:$2a$10$razd3L1aXndFfBNHO95aj.IVrFydsxkcQCcLmujmFQzll3hcUrY7S</passwordHash>
Restart Jenkins and login using below password:
test
Have a look at below thread: Reset Jenkins Configuration Command Line
With the limited information you have provided, i think you were pressing wrong credentials. However, i know of 2 options to fix this :
1) Go to your Jenkins installation Directory (Usually C:\Users\<UserID>\.jenkins\), look for config.xml - Check for below xml tags
useSecurity authorizationStrategy. You can play around with the values to get anonymous access/allow signup etc..
2) Re-install the jenkins itself - Remember to backup your jobs/workspace if you have already coded some jobs.
In case , you are installing as Jenkins as a 'Windows service' , then you can use username: admin & initial password: 'provided while installing Jenkins' to log in.
In addition to this answer, I had to do restart the Jenkins service for the change to take effect:
Go to the config folder (seems to be in one of the following for different versions):
# Windows (my machine)
C:\Users\<user>\AppData\Local\Jenkins\.jenkins\users\<jenkins username>_<random numbers>\config.xml
# Windows (Other)
C:\ProgramData\Jenkins\.jenkins\config.xml
# Linux
/jenkins/users/username/config.xml
# (Others?...)
Change contents of passwordHash tag for this:
<passwordHash>#jbcrypt:$2a$10$razd3L1aXndFfBNHO95aj.IVrFydsxkcQCcLmujmFQzll3hcUrY7S</passwordHash>
Restart Jenkins service:
# Windows
# (Inside Jenkins folder: C:\Program Files\Jenkins)
jenkins.exe restart
# Linux
sudo service jenkins restart
Login using your username and the password:
test
In mycase after commenting or removing the below line, it worked!
Goto:
C:\ProgramData\Jenkins.jenkins\config.xml
Remove the below line in config.xml:

Change JENKINS_HOME on Red Hat Linux?

I used this procedure to install Jenkins:
https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+RedHat+distributions
After it was up and running I discovered the /var/lib/jenkins partition on my server is very small. I want to move it, but I do not want to change the user that it runs under. I am new to Linux and I'm stumped. How do I move it for example to my Home/Public folder? The "Jenkins" user doesn't seem to have a Home folder. Its running as a daemon on startup, so I have no idea where to configure those settings.
Can I create a Home folder for the Jenkins user? How?
I read this article:
https://wiki.jenkins-ci.org/display/JENKINS/Administering+Jenkins
but do not understand HOW to "set the new Jenkins home". I have used the export command, and restarted the service, but the old path still shows up in the Manage Jenkins screens.
I've read the 2-3 similar questions on stackoverflow also, but there's always a big missing piece for me. Where to find that file where I change the path permanently?
Here's an easy way to solve your problem. First, move the Jenkins directory from /var/lib/jenkins to /home/jenkins. Then create a symlink at /var/lib/jenkins pointing to /home/jenkins. And of course, stop the Jenkins service before doing that.
sudo service jenkins stop
sudo mv /var/lib/jenkins /home
sudo ln -s /home/jenkins /var/lib/jenkins
sudo service jenkins start
I managed to change the home location for Jenkins by modifying content of /etc/sysconfig/jenkins file as follows:
JENKINS_HOME="/home/jenkins"
Okay, I reread your question a little bit more closely, lets see if we can figure this out. I am going to list some info that you may or may not know.
The jenkins installation and jenkins home are not the same thing. One is where the war file and other parts that jenkins needs to run live. jenkins_home is where your data is stored. By default, jenkins_home lives in ~/.jenkins. When you start jenkins, it looks for an environment variable to tell it where to find those files.
Jenkins runs as a seperate user, which, by default, is jenkins. This way it doesn't get in the way of you. The jenkins user will not have access to YOUR home directory, so that would be a poor solution. Ideally, it would have its own home directory, /home/jenkins. Your home directory could then be /home/jenkins/.jenkins. You say that folder doesn't exist- if you don't have access to it to create it yourself, that is perfectly fine, you can specify ANY folder. However, the jenkins user must have ownership of that folder to read and write to it.
It looks like Jenkins on redhat will be running with tomcat by default. The documentation for how to set environment variables for tomcat is https://wiki.jenkins-ci.org/display/JENKINS/Tomcat
This all gets set up with a script.https://wiki.jenkins-ci.org/display/JENKINS/JenkinsLinuxStartupScript seems to be the one that is used for this purpose. Even if you don't know anything about shell scripting, this isn't too hard... lines with a # are comments. The first line
JENKINS_USER=jenkins
sets the name of the user account jenkins will be using. Look down a littlle further, and you'll see the line
export JENKINS_BASEDIR=/home/jenkins
export CATALINA_OPTS="-DJENKINS_HOME=$JENKINS_BASEDIR/jenkins-home -Xmx512m -Djava.awt.headless=true"
This lets you set a directory to where jenkins should live, and then sets the jenkins_home directory to that /jenkins-home.
For your application, you may want to do something like this
export CATALINA_OPTS="-DJENKINS_HOME=/var/jenkinsmount/home -Xmx512m -Djava.awt.headless=true"
That would then store all of your build data (which is the part that grows!) at /var/jenkinsmount/home ... while leaving the rest of your files in their current location.
I haven't used it on redhat, but hopefully I explained enough for you to actually understand what is going on so that you can get it going!

I have faced the same issue and question.
Connecting some dots I could fix my Jenkins after I moved Jenkins to a new location due to the same issue -space in disk under /var/lib/jenkins.
Here is the procedures that I had to follow to get it working taking in consideration that I am pointing Jenkins to a non-default port. (I have applied this process into 2 servers)
First, move the Jenkins directory from /var/lib/jenkins to /opt/jenkins
sudo service jenkins stop
sudo mv /var/lib/jenkins /opt/
Now you can change your workspace and build directory to any other location on your machine.
Jenkins provides 3 predefined variables that can be used to specify the new location:
JENKINS_HOME — Jenkins home directory
ITEM_ROOTDIR — Root directory of a job for which the workspace is allocated
ITEM_FULLNAME — ‘/’-separated job name, like “foo/bar”
sudo su jenkins (access as Jenkins user)
JENKINS_HOME=/opt/jenkins
ITEM_ROOTDIR=/opt/jenkins
ITEM_FULLNAME=/opt/jenkins
exit (exit Jenkins user)
Now, edit the jenkins config
/opt/jenkins$ sudo nano /etc/default/jenkins
Modify the following line
#jenkins home location
#JENKINS_HOME=/var/lib/$NAME (here is the default)
JENKINS_HOME=/opt/jenkins (that is our new location)
change the home directory of a user
sudo usermod -d /opt/jenkins/ jenkins
sudo service jenkins start
If anyone is having issues with space and you have to relocate your jenkins, just wanted to reiterate that::
sudo service jenkins stop
sudo mv /var/lib/jenkins /home
sudo ln -s /home/jenkins /var/lib/jenkins
sudo service jenkins start
works great, so thanks to the person who posted that answer a few years ago!
Richard Chen's location is where I found the jenkins file on my CentOS 6.6 system.
sudo service jenkins stop
mv /var/lib/jenkins /home/mylocation/
(made sure the new location had correct ownership and group-- Jenkins)
modified the content of the file /etc/sysconfig/jenkins as follows:
JENKINS_HOME="/home/mylocation"
sudo service jenkins start
If all these don't work, then the only solution that works is to edit the following file
/lib/systemd/system/jenkins.service
then need to execute reloading of configs by running
systemctl daemon-reload
after this restarting the service would reflect the change.
Some commands work for me as below:
Step 1: Stop jenkin service and moving folder
systemctl stop jenkins
mv /var/lib/jenkins /whatever/folder
sudo chown jenkins -R /whatever/folder
Step 2: Modify jenkins home location in /etc/default/jenkins
JENKINS_HOME=/whatever/folder/$NAME
Step 3: Restart jenkins service
systemctl start jenkins
[A] Find your current jenkins home folder, if you are not aware where it is ?
Jenkins -> Manage Jenkins -> Configure System -> Check label 'Home directory'
[B] To move current Jenkins home folder to a new directory. Follow below steps :-
Stop Jenkins service - by killing the process
Follow one of below approach to set new home folder for JENKINS.
a) By default Jenkins home directory is set to ~/.jenkins
b) "JENKINS_HOME" environment variable setup in operating system.
c) "JENKINS_HOME" entry in JNDI environment.
d) "JENKINS_HOME" system property to the servlet container.
Tomcat context descriptor of the servlet, you can set below field in apache-tomcat-8.5.28/conf/context.xml :
<Context ...>
<Environment name="JENKINS_HOME" value="/path/to/jenkins_home/" type="java.lang.String"/>
</Context>
e) If jenkins.war file is deployed in a tomcat server , then even appending below content in bin/catalina.sh will setup JENKINS_HOME.
CATALINA_OPTS="-DJENKINS_HOME=/path_to/jenkins_home/"
Manually copy Jenkins home folder content from old to new home
folder. (use cp command) . Instead of moving, copy step is advised to keep one backup. Later you can delete old workspace.
Now start Jenkins, then It will pick the new home directory
from the path mentioned in JENKINS_HOME variable.
Note: - Just by setting above variable "JENKINS_HOME" to a different path will not copy
the files from current Jenkins home path to new one automatically. This copy step - you have to do it yourself, Manually.

iPad run with black screen in Jenkins

i configured out jenkins in way that it was launched under my account but when i build a project for my unit tests with KIF framework, Jenkins launches iPad simulator with black screen and nothing happens (jenkins also doesn't provide any useful information).
Can anyone advice to solution of this issue?
Please note that everything works just fine from command line.
Finally, i've found the solution need to use iPad Retina or iPad Retina (64-bit):
-destination OS=7.0,name=iPad Retina
So, the last supposed suggestion doesn't work either - need another solution.
Just ran into this myself. Following up on user2738882's self-answer, I have a fix for the pitfalls his solution has:
He's correct that it was occurring due to Jenkins being run as a launch daemon process. Daemon's are launched at start without login, but they aren't intended to have access to the UI. This is what causes the issue.
Unfortunately Jenkins defaults to installing as a launch daemon if you install via the Archive (.war).
The solution I went with is to move it over to a launch agent. To do so follow these steps:
sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist
sudo cp /Library/LaunchDaemons/org.jenkins-ci.plist /Users/<Path to Jenkins User>/Library/LaunchAgents/org.jenkins-ci.plist
Right click - > Get Info on the org.jenkins-ci.plist file
Change the read write permissions to all users (bottom)
Modify the plist file to change GroupName key value from "daemon" to "agent"
Right click -> Get Info again
Reset the file access to as it was before
sudo launchctl load /Users/<Path to Jenkins User>/Library/LaunchAgents/org.jenkins-ci.plist
The drawback of this approach is launch agents don't start until the user they're associated with logs in. In order to accommodate this I've configured my Jenkins user to login when the server starts up. To do this:
Open System Preferences
Open Groups & Users
Login Options
Set your Jenkins user as the Automatic Login:
This is obviously a security concern, but these machines should only ever be accessible on your local network and in a secure location anyway. Regardless I set the machine to show a screensaver as quickly as possible with a login.
The work-around that I see is that you can create AppleScript, which will run a simulator using terminal. Example:
do shell script "script"
where, script is your terminal command.
After script is created, add build step 'Execute shell script' to jenkins and write script which will run your AppleScript.
Example:
open /Applications/MyScript.app
The issue was in Jenkins and it was solved in the following way:
Stop the jenkins daemon via command:
sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist
Start Jenkins as process via command:
sudo nohup java -jar /Applications/Jenkins/jenkins.war --httpPort=8080 --ajp13Port=8010
And it works perfectly!
But there is a pitfall, after launching Jenkins under your user, all jobs disappear and you need to create it once again.

Jenkins, Executable and right

It seems that i have a permission problem to execute a .exe under windows with jenkins.
Things to know about the system:
I have a windows user called 'Tester'. This user has Administrator rights
Jenkins run as a service using Tester username
I have a job which does the following:
cd C:\Program Files (x86)\Jenkins\workspace\sahi\tools
toggle_IE_proxy.exe enable
The process is silent, no output. The executable must probably change some values in registry.
This command tick the checkbox "Use a proxy..."
Note: it is working fine when i execute the command above in a cmd.exe as user 'Tester'.
Do you have an idea what's happening there ?
Many thanks
It seems that turning Off UAC solved my problem

Jenkins Fail with: Host key verification failed

I downloaded and installed Jenkins for Mac OSX on my Macbook Pro (OS: Mountain Lion). I now want to set it up to pull down a project from bitbucket and do an automatic build.
I created the ssh key, added it to bitbucket and tried to setup a build job. However, I get the error:
Failed to connect to repository : Command "git ls-remote -h HEAD" returned status code 128:
stdout:
stderr: Host key verification failed.
fatal: The remote end hung up unexpectedly
I tried to remove the domain causing the problem from known_hosts but am still getting this error.
Please advise.
I think I've found a possible solution in this post: http://colonelpanic.net/2011/06/jenkins-on-mac-os-x-git-w-ssh-public-key/
Jenkins on Mac OS X I just finished setting up a build server on Mac
OS X using Jenkins (formerly Hudson). The company I’m working for
(GradeCam) uses git and gitolite for our source control and so I
expected no trouble using Jenkins to build our tools using the git
plugin.
However, I quickly ran into a snag: the source control server is on a
public address and so our source code is not available except via ssh,
and gitolite ssh access uses private key authentication. Well, I’m an
experience unix sysadmin, so that didn’t sound like a big issue —
after all, setting up public key authentication is childs play, right?
Default install
The default installation of Jenkins on Mac OS X (at the time of this
writing) installs a Launch Agent plist to
/Library/LaunchAgents/org.jenkins-ci.plist. This plist file causes
Jenkins to load as user “daemon”, which sounds fine — except that the
home directory for the “daemon” user is /var/root, same as for user
root. This means that the .ssh dir in there will never have the right
permissions for a private key to be used.
Creating a new hidden user
My solution was to create a new “hidden” user for Jenkins to run
under. Following instructions I found on a blog post, I created a user
“jenkins” with a home directory “/Users/Shared/Jenkins/Home”:
sudo dscl . create /Users/jenkins
sudo dscl . create /Users/jenkins PrimaryGroupID 1
sudo dscl . create /Users/jenkins UniqueID 300
sudo dscl . create /Users/jenkins UserShell /bin/bash
sudo dscl . passwd /Users/jenkins $PASSWORD
sudo dscl . create /Users/jenkins home /Users/Shared/Jenkins/Home/
I then stopped Jenkins: “sudo launchctl unload -w
/Library/LaunchAgents/org.jenkins-ci.plist” and edited the plist file
to set the username to jenkins instead of daemon.
“chown -R jenkins: /Users/Shared/Jenkins/Home”
sets the permissions how they need to be, and then “sudo launchctl
load -w /Library/LaunchAgents/org.jenkins-ci.plist” should get you up
and running!
To get git over ssh running, “sudo su – jenkins” to get a console as
the jenkins user and set up the ssh keys and such. Make sure you can
ssh to where you want to go (or even do a test git clone) because you
need to save the keys so it doesn’t ask for them when jenkins tries to
do the clone.
That should do you! Hope it helps someone.
