问题描述
我有一台Ubuntu 12.04的机器，并安装了Jenkins ver。 1.424.6使用基于this guide的apt-get，但有一个新版本：
New version of Jenkins (1.447.2) is available for download (changelog).
如果我按下载，我会得到一个jenkins.war文件……但是如何使用它来升级我当前的安装呢？或者在apt存储库更新之前是不可能的？
最佳解决思路
您可以使用新的jenkins.war文件覆盖现有的jenkins.war文件，然后重新启动Jenkins。
该文件通常位于/usr/share/jenkins中。
如果您的系统不是这种情况，则在Manage Jenkins -> System Information中，它将显示executable-war下.war文件的路径。
次佳解决思路
如果您已通过apt-get安装了Jenkins，则还应通过apt-get更新Jenkins以避免将来出现问题。更新应通过“apt-get更新”，然后“apt-get升级”。

第三种解决思路
#on ubuntu, in /usr/share/jenkins:
sudo service jenkins stop
sudo mv jenkins.war jenkins.war.old
sudo wget https://updates.jenkins-ci.org/latest/jenkins.war
sudo service jenkins start
第四种思路
apt-get update
apt-get upgrade
到目前为止，最简单的Linux升级方式，每次都像魅力一样。
第五种思路
虽然我不认为这是OP问题的有效答案，但我仍然强调在Ubuntu上部署Jenkins(可能是大多数(如果不是全部)库/软件包/软件)的最佳方法是利用aptitude(或apt-get)管理系统。
这里记录：https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu(请注意，如果你想使用LTS构建，请点击此repo http://pkg.jenkins-ci.org/debian-stable/)
因此，如果你真的使用这种方法，你只需要做一个apt-get upgrade jenkins
第六种思路
我们使用以下命令从.war文件运行jenkins。
java -Xmx2500M -jar jenkins.war --httpPort=3333 --prefix=/jenkins
您甚至可以从〜/Downloads目录运行命令
第七种思路
我使用这个groovy脚本下载新的war文件
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')
另一个脚本关闭tomcat – 复制战争并重新启动它
我们在windows 2008和tomcat上托管它，我使用sc查询，sc config，sc stop，sc start来管理windows服务
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
第八种思路
https://wiki.jenkins.io/display/JENKINS/Installing+Jenkins+on+Ubuntu
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.
