从战争档案中更新 Jenkins

最佳答案

You can overwrite the existing jenkins.war file with the new one and then restart Jenkins.

This file is usually located in /usr/share/jenkins.

If this is not the case for your system, in Manage Jenkins -> System Information, it will display the path to the .war file under executable-war.

If you have installed Jenkins via apt-get, you should also update Jenkins via apt-get to avoid future problems. Updating should work via "apt-get update" and then "apt-get upgrade".

We run jenkins from the .war file with the following command.

java -Xmx2500M -jar jenkins.war --httpPort=3333 --prefix=/jenkins

You can even run the command from the ~/Downloads directory

Mine is installed under /usr/share/jenkins I thought it was installed via apt-get so might want to check there as well.

Ubuntu 12.04.1

Though I wouldn't consider this as a valid answer to OP's question, I'd still emphasize that the best way to deploy Jenkins (and likely most if not all libraries/packages/software) on Ubuntu is to leverage aptitude (or apt-get) management system.

It is documented here: https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu (notice that if you want to use the LTS build, hit on this repo http://pkg.jenkins-ci.org/debian-stable/)

So if by any chance you actually did use this approach, you'd simply do a apt-get upgrade jenkins

I use this groovy script to download new war file

import java.util.concurrent.atomic.AtomicInteger


class ThreadHelper{
static done = false;
static starttime = System.currentTimeMillis()
static synchronized printx (message) {    printf ("%5s seconds: %20s",(System.currentTimeMillis()-starttime)/1000.0 , message); println("") }
def download(address)
{
def filename = new File(System.getenv()['CI_HOME'] + '/' + address.tokenize("/")[-1])
println(filename.getCanonicalPath())
def file = new FileOutputStream(filename)
def out = new BufferedOutputStream(file)
out << new URL(address).openStream()
out.close()
done=true;
}


}


println("executing from ... "+ new File(".").getCanonicalPath())


def counter = new AtomicInteger();
th = Thread.start {
while(!ThreadHelper.done) {
sleep 1000
counter.incrementAndGet()
print '.'
}
}


th2 = Thread.start { new ThreadHelper().download("http://mirrors.jenkins-ci.org/war/latest/jenkins.war") }
th.join()
th2.join()


ThreadHelper.printx('done')

And another script shutsdown tomcat - copies the war and restarts it

We host it on windows 2008 and tomcat, I use sc query, sc config, sc stop, sc start to manage windows services

    set warname=jenkins


if '%name%' == 'trak' set warname=trak


pushd .
if '%name%'=='' goto badname
if '%warname%'=='' goto badname


if '%ci_home%'=='' goto badcihome


REM =====================================================
REM stop windows service
sc stop %name%


REM sleep for 5 seconds see http:\\stackoverflow.com\questions\1672338\how-to-sleep-for-5-seconds-in-windowss-command-prompt-or-dos
ping 1.1.1.1 -n 1 -w 3000 > nul


rem replace forward slash with backward slash
set tomcat_dir=%ci_home:/=\%\instances\tomcat7-%name%


REM Create sub directory called bak-yymmdd-hhmmss
REM where yymmdd-hhmmss is a date-time stamp like 120601-142907


set hh=%time:~0,2%


REM Since there is no leading zero for times before 10 am, have to put in
REM a zero when this is run before 10 am.


if "%time:~0,1%"==" " set hh=0%hh:~1,1%


set yymmdd_hhmmss=%date:~12,2%%date:~4,2%%date:~7,2%-%hh%%time:~3,2%%time:~6,2%


set backupdir=bak-%yymmdd_hhmmss%


REM =====================================================
md %tomcat_dir%\logs\%backupdir%


cd %tomcat_dir%\logs


dir bak*
echo "nothing-to-log" >> force.log


REM move command will fail if there is nothing to move hence the force log statement above


call move *.* %backupdir%


REM =====================================================
rmdir %tomcat_dir%\webapps\%name% /q/s


echo f|xcopy %ci_home%\%warname%.war %tomcat_dir%\webapps\%name%.war /y


REM TODO===== something about jenkins plugins


REM =====================================================
cd "%tomcat_dir%\bin"
call catalina version


echo =====================================================
echo ====== removing %name%
call service remove %name%


echo =====================================================
echo ====== installing %name%
call service install %name%


echo on


REM setting service to start automatically, note that space before the word auto IS REQUIRED
sc config %name% start= auto


REM =====================================================
sc start %name%


popd


exit 0


goto done


:badname
echo 'name required - this will be used as windows service name as well'
pause
exit 1


:badcihome
echo 'CI home env var required - ci_home'
pause
exit 1


:done

I didn't want to install the x11-common and other components that come bundled in the apt-get install approach, so I just downloaded the .war file and ran the command Francois mentioned. That worked nicely, but you have to write your own daemon script with that approach. Full details here: http://strem.in/stream/9488/Using-the-war-file-for-jenkins-ci

apt-get update
apt-get upgrade

by far the easiest way to upgrade on linux, works like a charm everytime.

Once installed like this, you can update to the later version of Jenkins (when it comes out) by running the following commands:
-------
sudo apt-get update
sudo apt-get install jenkins
-------
(aptitude or apt-get doesn't make any difference.)
What does this package do?
Jenkins will be launched as a daemon up on start. See /etc/init.d/jenkins for more details.
The 'jenkins' user is created to run this service.
Log file will be placed in /var/log/jenkins/jenkins.log. Check this file if you are troubleshooting Jenkins.
/etc/default/jenkins will capture configuration parameters for the launch like e.g JENKINS_HOME
By default, Jenkins listen on port 8080. Access this port with your browser to start configuration.

#on ubuntu, in /usr/share/jenkins:

To Upgrade Jenkins WAR file, follow the steps below:

Stop Jenkins server using command: systemctl stop jenkins
Go to Jenkins war location: ex: /usr/lib/jenkins
Take a backup from jenkins.war: mv jenkins.war jenkins.war_bkp
Download Jenkins using wget or curl command: wget http://updates.jenkinsci.org/download/war/(version)/jenkins.war
Starting Jenkins server using command: systemctl start jenkins
Check Jenkins server status using command: systemctl status jenkin

when you open the Jenkins panel it will show available package from their latest version. you can download it via wget command in the server.after download the latest package you should take .war backup file.

Eg-: wget http://updates.jenkins-ci.org/download/war/2.205/jenkins.war

Jenkins war file path for Ubuntu - /usr/share/jenkins/

Jenkins war file path for centos - /usr/lib/jenkins/

after taking backup overwrite the war file and restart the jenkins service.

Ubuntu - service jenkins restart , centos - systemctl restart jenkins.service

By far easiest way to upgrade jenkins inside ubuntu as Vasan said.

apt-get update apt-get upgrade

小开

This could be done in two ways

Directly download the .war file and replace it with the existing one.
update directly from ubuntu

1st Method

If you are not able to find jenkins war file in standard path, you can goto Manage Jenkins → System Information, it will display the path to the .war file.

The common location of Jenkins war file on the ubuntu server is:

/usr/share/jenkins

Jump to jenkins home directory

cd /usr/share/jenkins

Stop the jenkins server

sudo service jenkins stop

Move existing jenkins war file

sudo mv jenkins.war jenkins.war.old

Download latest jenkins war file

sudo wget https://updates.jenkins-ci.org/latest/jenkins.war

Start the Jenkins server

sudo service jenkins start

Everything should be good now.

Troubleshooting steps

If you are running jenkins using root permissions, (which you should not be doing), you need to change the jenkins.war permissions.

$ sudo chown root:root jenkins.war

You can optionally restart the jenkins server using below command:

$ sudo /etc/init.d/jenkins restart

2nd Method

On ubuntu, you can also try the below two commands to update everything:

$ sudo apt-get update
$ sudo apt-get install jenkins --fix-missing

In the latest version of Jenkins, the jenkins.war file location has been changed.
updatedb && locate jenkins.war command can be used to check the new path which is: /usr/share/java/.
Replace the old .war file with the new one under /usr/share/java/ directory and restart the Jenkins to upgrade it.
