I'm trying to follow the directions here: https://wiki.jenkins-ci.org/display/JENKINS/Running+Jenkins+behind+Apache to set up my Jenkins server to appear at http://myhost/jenkins. It works, but the Jenkins website thinks http://myhost/ is the jenkins/ root.
I believe this problem is caused by the first warning flag on that web page, i.e. that my context path is not set correctly. However, I can't figure out where to set the context path. The instructions for ubuntu and windows are clear enough, but on Mac OS X 10.6, there is no jenkins.xml file, no /etc/default/jenkins file, and nothing of relevance I can see in ~/.jenkins/config.xml.
So, what am I missing? Where can I tell jenkins that its root is in /jenkins/ instead of /?
Paraphrasing from the document you mentioned;
You need to specify the context/prefix of the Jenkins instance, this can be done by modifying the Jenkins configuration as follows;
Either, set the context path by modifying the jenkins.xml configuration file and adding --prefix=/jenkins (or similar) to the entry.
Or Set the context path when using by adding --prefix=/jenkins to JENKINS_ARGS in /etc/default/jenkins (Ubuntu) or in an appropriate startup file.
So, how to find these things...
The Jenkins.xml file should be in the $JENKINS_HOME directory, I'm not sure if Mac OS has the "updatedb" and "locate " commands, but you could try doing updatedb && locate jenkins.xml
Also, have a look in the startup scripts; /etc/init.d if installed from a package, or add the JENKINS_ARGS to the environment properties for the User running Jenkins (append to ~user/.profile) or the arguments for the container running Jenkins.
Be aware that if your Jenkins installation (without the prefix argument) was running under:
http://myserver:8080/ => 200 Jenkins is here
adding --prefix=/ci/dashboard in the arguments will produce this behaviour:
http://myserver:8080/ => 404
http://myserver:8080/ci/dashboard => 200 Jenkins is now here
Not sure where to look in config.xml, but at http://myhost/jenkins/configure, there's an option called "Jenkins URL" that you can use to set that.
Just to provide some recent confirmation of the suggested approaches, on CentOS 7, with Jenkins 1.610, I was able to achieve this by changing jenkinsUrl in jenkins.model.JenkinsLocationConfiguration.xml to the desired one (e.g. http://127.0.0.1:8080/jenkins), adding
JENKINS_ARGS="--prefix=/jenkins"
inside /etc/sysconfig/jenkins, and restarting Jenkins.
FYI the Jenkins installation was made via Puppet, using this Puppet module.
Add prefix attribute to /etc/default/jenkins file:
JENKINS_ARGS="--webroot=/var/cache/jenkins/war --prefix=/jenkins --httpPort=$HTTP_PORT --ajp13Port=$AJP_PORT
Configure your web server (e.g. - nginx) to redirect /jenkins to localhost:8080;
Put this into /etc/apache2/other/jenkins.conf:
ProxyPass /jenkins http://localhost:8009/jenkins
ProxyPassReverse /jenkins http://localhost:8009/jenkins
ProxyRequests Off
<Proxy http://localhost:8009/jenkins*>
Order deny,allow
Allow from 127.0.0.1
</Proxy>
Then execute these commands:
sudo defaults write /Library/Preferences/org.jenkins-ci httpPort 8009
sudo defaults write /Library/Preferences/org.jenkins-ci prefix /jenkins
sudo launchctl stop org.jenkins-ci
The last command tells launchd to stop the running instance of Jenkins. And a new one will automatically be started because the launchd has been configured to always keep Jenkins running.
This is how I fixed it under Debian Wheezy running Jenkin 1.557
in /etc/default/jenkins , modify the JENKINS_ARGS line by adding "--prefix=$PREFIX"
JENKINS_ARGS=" ..... --prefix=$PREFIX"
you need to edit jenkins config file in directory
such like :
sudo vi /etc/default/jenkins and change var HTTP_PORT
next restart jenkins
sudo /etc/init.d/jenkins restart
hope this is helpful
I'm using CentOS7, add JENKINS_ARGS="--prefix=/jenkins" to /etc/sysconfig/jenkins and restart Jenkins worked. Then you can visit via ip:8080/jenkins
I'm not sure if people are still looking for this, but as I just ran across it, I figured I'd post my solution here.
By following the instructions at here, I was able to set the context located in Library/Preferences/org.jenkins-ci.plist to a more preferable address. The link has all the settings you can edit with an OS X native install.
I needed to configure Jenkins on a CentOS box via Puppet using the rtyler/jenkins module. Looking through the module code might suggest that HTTP_PORT and PREFIX should be the parameters in the config_hash but this did not work for me. What worked for me was something like the following Puppet configuration:
class { 'jenkins':
config_hash => {
'JENKINS_PORT' => { 'value' => '8085' },
'JENKINS_ARGS' => { 'value' => '--prefix=/jenkins' },
},
}
I was able to confirm that this updated the contents of "/etc/sysconfig/jenkins" (I believe this is the CentOS/RedHat file location).
For a Windows installation add the prefix within the <arguments> tag (jenkins.xml) and restart the service (Powershell Restart-Service jenkins). E.g.:
<executable>%BASE%\jre\bin\java</executable>
<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8080 --webroot="%BASE%\war" --prefix=/jenkins</arguments>
For a few days I am trying to set Jenkins on Tomcat7 without any result... I read many tutorials and I could not find any help...
I set a virtual system on VirtualBox -> Ubuntu 12.04.04
Using apt-get I installed tomcat7, and then Jenkins.
While using them separately by usingcommad sudo service tomcat7 start or sudo service jenkins start both services starts and are visable on my localhost.
However, when I copied jenkins.war to /var/lib/tomcat7/webapps I cannot run it via tomcat.
I have set JENKINS_HOME as /var/lib/jenkins.
In the folder /usr/share/tomcat7 i run these commands: sudo mkdir .jenkins | sudo chown tomcat7:nogroup .jenkins
And from localhost:8080/manager jenkins is viable:
When I try localhost:8080/jenkins as tutorials says I get en error message:
I really have no idea what am I doing wrong...
What else may I try to make it work?
I had the same issue. Please check Java compatibility version with the "Jenkins.war" file. I used Java 8 for Jenkins version 2.107.1.
I would suggest to shutdown restart the tomcat server. As it should be able to read the .war file. Hence, you will go through additional setup.
Check the version of your jenkins.war file
Check the compatibe java version for hat jenkins version in web
Download that version of java and define system environment variables path for JAVA_HOME
Open "Monitor tomcat" in that JAVA define the path of jvm.dll
example C:\Program Files\Java\jdk-11.0.16\bin\server\jvm.dll
This picture shows how to run in windows:
Please check your JRE path, as I face a similar issue where JRE_HOME was incorrectly set
JRE_HOME=/usr/jdk/jdk1.6.0_21,
It started working when I correct it to latest JRE version
JRE_HOME=/usr/jdk/jdk1.7.0_09/jre.
I'm trying create environment variable in tomcat 8 for my project, I need use this variable for choice properties logger. I read about setenv.sh and i create this file, but when i run my project - it does not run. How me create environment variable for check my project?
I read about setenv in this site. I use ubuntu 14.04.
setenv.sh
JAVA_HOME="/usr/lib/jvm/java-8-oracle"
export JAVA_HOME
JAVA_OPTS="-Xmx4096m -Xms512m -server"
export JAVA_OPTS
CATALINA_HOME="/opt/tomcat"
export CATALINA_HOME
Please do the following. It'll work for you.
1 sudo su and cd to /var/lib/tomcat8/bin/
2 touch setenv.sh(if it doesn't exist)
3 chmod 777 setenv.sh
4 vim setenv.sh and set following line in setenv.sh
export varriable=value
5 sudo service tomcat8 restart
and Enjoy...!!
Rather than create /usr/share/tomcat8/bin/setenv.sh, you can put those settings in /etc/default/tomcat8.
I've found that setting JAVA_HOME in setenv.sh causes tomcat8 to not start up properly if it doesn't match what /etc/init.d/tomcat8 comes up with. The init.d script ignores setenv.sh but needs to know which java version is used so that it can check the process list to see if tomcat is running. The init.d script does use /etc/default/tomcat8, so it makes sense to delete setenv.sh and just put the settings in /etc/default.
There is an alternate way if we're using eclipse:
Go to Servers tab
Double click on the server
Click Open launch configuration
Go to Environment tab
Click New and set the key-value pair of environment variables

I am running Jenkins from user jenkins thats has $PATH set to something and when I go into Jenkins web interface, in the System Properties window (http://$host/systemInfo) I see a different $PATH.
I have installed Jenkins on Centos with the native rpm from Jenkins website. I am using the startup script provided with the installation using sudo /etc/init.d/jenkins start
Can anyone please explain to me why that happens?
Michael,
Two things:
When Jenkins connects to a computer, it goes to the sh shell, and not the bash shell (at least this is what I have noticed - I may be wrong). So any changes you make to $PATH in your bashrc file are not considered.
Also, any changes you make to $PATH in your local shell (one that you personally ssh into) will not show up in Jenkins.
To change the path that Jenkins uses, you have two options (AFAIK):
1) Edit your /etc/profile file and add the paths that you want there
2) Go to the configuration page of your slave, and add environment variable PATH, with value: $PATH:/followed-by/paths/you/want/to/add
If you use the second option, your System Information will still not show it, but your builds will see the added paths.
I kept running into this problem, but now I just add:
source /etc/profile
As the first step in my build process. Now all my subsequent rules are loaded for Jenkins to operate smoothly.
You can also edit the /etc/sysconfig/jenkins file to make any changes to the environment variables, etc. I simply added source /etc/profile to the end of the file. /etc/profile has all all of the proper PATH variables setup. When you do this, make sure you restart Jenkins
/etc/init.d/jenkins restart
We are running ZendServer CE which installs pear, phing, etc in a different path so this was helpful. Also, we don't get the LD_LIBRARY_PATH errors we used to get with Oracle client and Jenkins.
I tried /etc/profile, ~/.profile and ~/.bash_profile and none of those worked. I found that editing ~/.bashrc for the jenkins slave account did.
The information on this answer is out of date. You need to go to Configure Jenkins > And you can then click to add an Environment Variable key-value pair from there.
eg: export MYVAR=test would be MYVAR is the key, and test is the value.
I found two plugins for that.
One loads the values from a file and the other lets you configure the values in the job configuration screen.
Envfile Plugin — This plugin enables you to set environment variables via a file. The file's format must be the standard Java property file format.
EnvInject Plugin — This plugin makes it possible to add environment variables and execute a setup script in order to set up an environment for the Job.
On my newer EC2 instance, simply adding the new value to the Jenkins user's .profile's PATH and then restarting tomcat worked for me.
On an older instance where the config is different, using #2 from Sagar's answer was the only thing that worked (i.e. .profile, .bash* didn't work).
Couldn't you just add it as an environment variable in Jenkins settings:
Manage Jenkins -> Global properties > Environment variables:
And then click "Add" to add a property PATH and its value to what you need.
This is how I solved this annoying issue:
I changed the PATH variable as #sagar suggested in his 2nd option, but still I got different PATH value than I expected.
Eventually I found out that it was the EnvInject plugin that replaced my PATH variable!
So I could either uninstall EnvInject or just use it to inject the PATH variable.
As many of our Jenkins jobs use that plugin, I didn't want to uninstall it...
So I created a file: environment_variables.properties under my Jenkins home directory.
This file contained the path environment value that I needed:
PATH=$PATH:/usr/local/git/bin/.
From the Jenkins web interface: Manage Jenkins -> Configure System.
In that screen - I ticked the Prepare jobs environment option, and in the Properties File Path field I entered the path to my file: /var/lib/jenkins/environment_variables.properties.
This way every Jenkins job we have receive whatever variables I put in this environment_variables.properties file.
Jenkins also supports the format PATH+<name> to prepend to any variable, not only PATH:
Global Environment variables or node Environment variables:
This is also supported in the pipeline step withEnv:
node {
withEnv(['PATH+JAVA=/path/to/java/bin']) {
...
}
}
Just take note, it prepends to the variable. If it must be appended you need to do what the other answers show.
See the pipeline steps document here.
You may also use the syntax PATH+WHATEVER=/something to prepend /something to $PATH
Or the java docs on EnvVars here.
I only had progress on this issue after a "/etc/init.d/jenkins force-reload". I recommend trying that before anything else, and using that rather than restart.
On my Ubuntu 13.04, I tried quite a few tweaks before succeeding with this:
Edit /etc/init/jenkins.conf
Locate the spot where "exec start-stop-server..." begins
Insert the environment update just before that, i.e.
export PATH=$PATH:/some/new/path/bin
Add
/usr/bin/bash
at
Jenkins -> Manage Jenkins -> configure System -> Shell->Shell
executable
Jenkins use the sh so that even /etc/profile doesn't work for me
When I add this, I have all the env.
Solution that worked for me
source ~/.bashrc
Explanation
I first verified Jenkins was running BASH, with echo $SHELL and echo $BASH (note I'm explicitly putting #!/bin/bash atop the textarea in Jenkins, I'm not sure if that's a requirement to get BASH). sourceing /etc/profile as others suggested was not working.
Looking at /etc/profile I found
if [ "$PS1" ]; then
...
and inspecting "$PS1" found it null. I tried spoofing $PS1 to no avail like so
export PS1=1
bash -c 'echo $PATH'
however this did not produce the desired result (add the rest of the $PATH I expect to see). But if I tell bash to be interactive
export PS1=1
bash -ci 'echo $PATH'
the $PATH was altered as I expected.
I was trying to figure out how to properly spoof an interactive shell to get /etc/bash.bashrc to load, however it turns out all I needed was down in ~/.bashrc, so simply sourceing it solved the problem.
I tried all the things from above - didn't work for me.
I found two solution (both for SSH-Slave)
Go to the slave settings
Add a new environment variable
PATH
${PATH}:${HOME}/.pub-cache/bin:${HOME}/.local/bin
The "${HOME}" part is important. This makes the additional PATH absolute.
Relative path did not work for me.
Option II (pipeline-script)
pipeline {
agent {
label 'your-slave'
}
environment {
PATH = "/home/jenkins/.pub-cache/bin:$PATH"
}
stages {
stage('Test') {
steps {
ansiColor('xterm') {
echo "PATH is: $PATH"
}
}
}
}
}
On Ubuntu I just edit /etc/default/jenkins and add source /etc/profile at the end and it works to me.
Running the command with environment variable set is also effective. Of course, you have to do it for each command you run, but you probably have a job script, so you probably only have one command per build. My job script is a python script that uses the environment to decide which python to use, so I still needed to put /usr/local/bin/python2.7 in its path:
PATH=/usr/local/bin <my-command>
What worked for me was overriding the PATH environment for the slave.
Set: PATH
To: $PATH:/usr/local/bin
Then disconnecting and reconnecting the slave.
Despite what the system information was showing it worked.
I have Jenkins 1.639 installed on SLES 11 SP3 via zypper (the package manager).
Installation configured jenkins as a service
# service jenkins
Usage: /etc/init.d/jenkins {start|stop|status|try-restart|restart|force-reload|reload|probe}
Although /etc/init.d/jenkins sources /etc/sysconfig/jenkins, any env variables set there are not inherited by the jenkins process because it is started in a separate login shell with a new environment like this:
startproc -n 0 -s -e -l /var/log/jenkins.rc -p /var/run/jenkins.pid -t 1 /bin/su -l -s /bin/bash -c '/usr/java/default/bin/java -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --javaHome=/usr/java/default --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --httpPort=8080 --ajp13Port=8009 --debug=9 --handlerCountMax=100 --handlerCountMaxIdle=20 &' jenkins
The way I managed to set env vars for the jenkins process is via .bashrc in its home directory - /var/lib/jenkins. I had to create /var/lib/jenkins/.bashrc as it did not exist before.
1- add to your profil file".bash_profile" file
it is in "/home/your_user/" folder
vi .bash_profile
add:
export JENKINS_HOME=/apps/data/jenkins
export PATH=$PATH:$JENKINS_HOME
==> it's the e jenkins workspace
2- If you use jetty :
go to jenkins.xml file
and add :
<Arg>/apps/data/jenkins</Arg>
Here is what i did on ubuntu 18.04 LTS with Jenkins 2.176.2
I created .bash_aliases file and added there path, proxy variables and so on.
In beginning of .bashrc there was this defined.
# If not running interactively, don't do anything
case $- in
*i*) ;;
*) return;;
esac
So it's checking that if we are start non-interactive shell then we don't do nothing here.
bottom of the .bashrc there was include for .bash_aliases
# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi
so i moved .bash_aliases loading first at .bashrc just above non-interactive check.
This didn't work first but then i disconnected slave and re-connected it so it's loading variables again. You don't need to restart whole jenkins if you are modifying slave variables. just disconnect and re-connect.
If your pipeline is executed on the remote node that is connected via SSH, then actually Jenkins runs agent application that performs incoming actions.
By default zsh shell is used, not the bash (my Jenkins has version 2.346.3).
Furthermore jenkins-agent runs non-login shell which makes default PATH values even if you put some configuration to .zshrc. It will be skipped.
My choice is to put the following shebang at a script start
#!/bin/bash -l
-l option makes bash to run in the login mode and in this case bash performs configurations specified in /etc/profile and ~/.bash_profile.
If you run script in Jenkins pipeline it will look like:
steps {
sh '''#!/bin/bash -l
env
'''
}
