jenkins 主从配置

配置免密码

#主jenknis
su jenkins
ssh-keygen
ssh-copy-id root@192.168.88.11

从jenkins安装jdk

Pipeline配置

安装2台tomcat用于测试

sudo apt-get install tomcat8
/etc/init.d/tomcat8 start

mkdir -p /data/tomcat/test
rm -rf /var/lib/tomcat8/webapps/*
ln -s /data/tomcat/test/ROOT/ /var/lib/tomcat8/webapps/

需要提前开通gitlab账号密码

Jenkinsfile 提前上传到gitlab项目中

node("jekins-agent1") 表示在jenkins从执行任务

Jenkinsfile

node("jekins-agent1"){
    stage("clone 代码"){
        sh "cd /home/jenkins/workspace/test  && rm -rf ./*"
        git credentialsId: '234d25df-a08d-46f6-a039-b7751e1944c3', url: 'http://192.168.88.10/root/test.git'
    }
    stage("代码构建"){
        sh "cd /home/jenkins/workspace/test  && tar czvf devops.tar.gz ./*"
    }
    
   stage("停止服务"){
    sh 'ssh sdn@192.168.88.12 "sudo /etc/init.d/tomcat8 stop && sudo rm -rf /data/tomcat/test/*"'
    sh 'ssh sdn@192.168.88.13 "sudo /etc/init.d/tomcat8 stop && sudo rm -rf /data/tomcat/test/*"'
   }
   
    stage("代码copy"){

    sh "cd /home/jenkins/workspace/test && scp devops.tar.gz   sdn@192.168.88.13:/data/tomcat/test/"
    }

        sh 'ssh sdn@192.168.88.12 "cd  /data/tomcat/test/ && tar xvf devops.tar.gz -C /data/tomcat/test/ && rm -rf devops.tar.gz"'

    sh 'ssh sdn@192.168.88.13 "sudo /etc/init.d/tomcat8 start"'
