Jenkinsfile

将build完成的二进制文件、static、service.sh生产压缩包。 移动到发布目录,发布,解压包,启动服务。

String buildShell = "${env.buildShell}"
String targetHosts = "${env.targetHosts}"
String targetDir = "${env.targetDir}"
String serviceName = "${env.serviceName}"
String user = "${env.user}"

    }
    
    stage("build"){

服务控制脚本

#!/bin/bash

targetDir=$2

start(){
    cd ${targetDir}
    nohup ./main >>/dev/null 2>&1& echo $! > service.pid
    cd -
    
}


stop(){
    pid=`cat service.pid`
    if [ -z $pid ]
    then 
        echo "pid"
    else
        kill -9 ${pid}
        kill -9 ${pid}
