jenkins 迁移， jenkins.war 安装方式

具体操作

# 基础环境
# 旧jenkins
# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)

# jenkins 家目录及配置
# ls /home/jenkins-master/
backup  jenkins  jenkins.war  start.sh  stop.sh



# 新机器基础环境
# uname -r
4.14.238-182.422.amzn2.x86_64


# 以下是迁移步骤
# 首先新机器创建用户
useradd jenkins

# 拷贝jenkins文件及配置信息
# 因为backup文件夹是备份数据，所以这里掠过该目录
rsync -artvz -e 'ssh' /home/jenkins-master/ awscn-jenkins:/home/jenkins --exclude=backup

# 该目录下方的是jenkins的配置信息
rsync -artvz -e 'ssh' /root/.jenkins/ awscn-jenkins:/root/.jenkins


# 启动脚本
# cat /home/jenkins-master/start.sh
#!/bin/bash

HOST=0.0.0.0
PORT=9090
java -jar jenkins.war --httpListenAddress=$HOST --httpPort=$PORT &


# 停止脚本
# cat /home/jenkins-master/stop.sh
#!/bin/bash

pid=$(ps axu |awk '/httpPort=9090/{print $2}')
for i in ${pid};do
  kill -9 ${i};
done


# 拷贝完数据后启动服务
su - jenkins -c "cd /home/jenkins/;sh start.sh"


# 添加到开机启动
# tail  /etc/rc.local

su - jenkins -c "cd /home/jenkins/;sh start.sh"
