【Linux】Jenkins以war包运行及开机启动配置（四）

　　本例介绍jenkins已war包运行及开机启动配置

　　环境：Linux环境（CentOS 7.4）

以war包运行

　　1、下载jenkins.war包

　　2、启动war包（默认端口：8080，默认JENKINS_HOME目录：～/.jenkins ）

　　　　前台启动命令：java -jar jenkins.war

　　　　后台启动命令：nohup java -jar jenkins.war &

　　3、使用浏览器打开地址：http://ip:8080，即可访问到jenkins

　　　　关闭jenkins，页面访问地址：http://ip:8080/exit

　　　　重启jenkins，页面访问地址：http://ip:8080/restart

　　4、其他安装参考【Linux】Jenkins安装（一）

　　5、修改JENKINS_HOME目录启动，需要新建一个脚本jenkins.sh，然后运行脚本　

 #!/bin/bash

 # 导入JENKINS_HOME环境变量

 export JENKINS_HOME=/data/soft/jenkins

 cd $JENKINS_HOME

 # 启动Jenkins

 nohup java -jar jenkins.war  --ajp13Port=- --httpPort= >/dev/null >& &

　　6、构建shell，demo如下：

 #!/bin/bash

 # 编译+部署zeus站点

 # 保持Jenkins启动的Service（tomcat） 不被杀死

 export BUILD_ID=dontKillMe

 # 需要配置如下参数

 # 项目路径，在Execute Shell中国配置项目路径， pwd 就可以获得项目路径

 # export PROJ_PATH=这个jenkins任务在部署机器上的路径

 export PROJ_PATH=`pwd`

 # 输入你在环境上tomcat的全路径

 # export TOMCAT_APP_PATH=tomcat在部署机器上的路径

 export TOMCAT_APP_PATH=/data/soft/apache-tomcat-

 ### base 函数

 killTomcat()

 {

     pid=`ps -ef | grep tomcat- | grep -v grep | awk '{print $2}'`

     echo "Tomcat Id is : $pid"

     if [ ! -n "$pid" ];

     then

         echo "No Tomcat Pid alive"

     else

         echo "Tomcat Pid alive"

     fi

 }

 cd $PROJ_PATH/god-site

 pwd

 mvn clean package

 # 停tomcat

 killTomcat

 # 删除原有工程

 rm -rf $TOMCAT_APP_PATH/webapps/zeus.war

 # 复制新的工程

 cp $PROJ_PATH/god-site/god-web/god-web-zeus/target/zeus.war $TOMCAT_APP_PATH/webapps/

 # 启动Tomcat

 cd $TOMCAT_APP_PATH

 sh bin/startup.sh

　　补充：

　　使用java -jar 命令的时候可以加入启动参数，启动命令格式：java -jar jenkins.war [--option=value] [--option=value]，

　　到达一些配置效果，例如：

　　　　修改jenkins端口启动命令：java -jar jenkins.war --httpPort=18080

　　其他启动参数查看命令：java -jar jenkins.war --help

 [root@H__D jenkins]# java -jar jenkins.war --help

开机启动配置

　　参考：【Linux】开机自动启动脚本

　　1、编写启动脚本jenkins

　　　　命令：vim /data/soft/jenkins/jenkins.sh

 #!/bin/bash 

 # 导入环境变量

 export JENKINS_HOME=/data/soft/jenkins

 export JAVA_HOME=/data/soft/jdk1..0_181

 cd $JENKINS_HOME 

 pid=`ps -ef | grep jenkins.war | grep -v 'grep'| awk '{print $2}'`

   if [ "$1" = "start" ];then

   if [ -n "$pid" ];then

   echo 'jenkins is running...'

 else

   ### java启动服务 配置java安装根路径,和启动war包存的根路径

   nohup $JAVA_HOME/bin/java  -Xms128m -Xmx256m   -jar $JENKINS_HOME/jenkins.war  --ajp13Port=- --httpPort= >/dev/null >& &

   fi

   elif [ "$1" = "stop" ];then

   exec ps -ef | grep jenkins | grep -v grep | awk '{print $2}'| xargs kill -

   echo 'jenkins is stop...'

 else

   echo "Please input like this:"./jenkins.sh start" or "./jenkins stop""

   fi

　　2、给jenkins.sh文件授权

　　　　命令：chmod +x /data/soft/jenkins/jenkins.sh

　　3、在/etc/rc.d/rc.local文件底部，添加内容：

 # jenkins

 /data/soft/jenkins/jenkins.sh start

　　4、重启计算机

　　　　命令：reboot

Jenkins常用功能

　　1、备份、迁移、恢复jenkins

　　首先找到JENKINS_HOME，因为Jenkins的所有的数据都是以文件的形式存放在JENKINS_HOME目录中。不管是迁移还是备份，只需要操作JENKINS_HOME就行了。

　　迁移：建议将JENKINS_HOME打包后在拷贝，windows可以用zip，rar等，Linux有zip，tar等，然后将打包的文件解压到新的JENKINS_HOME目录就行了。

　　备份：如果是临时备份，整个压缩文件就行了。

　　恢复：恢复的时候需要先停止jenkins。

　　2、升级Jenkins

　　Jenkins的开发迭代非常快，每周发布一个开发版本，长期支持版每半年更新一次(ps:大版本更新)。如此频繁的更新，怎么升级呢？

　　war：下载新版的war文件，替换旧版本war文件。重启即可。

　　二进制：卸载旧版本，安装新版本即可。
