jenkins利用pipeline进行回滚

一 利用jar包名字查找pid

1 设置项目和要回滚的主机

2 选择jar包名字

3 执行回滚脚本

4 脚本内容

回滚脚本

#!/bin/bash

        parentDirectory=$4
        remote_port=22
        remote_user=root

        echo "remote_ip:${remote_ip}"
        local_dir=/home/yw/git_project

case   "$@" in
        *)
                packageName="$1"

                remote ${packageName%.*} ${packageName} ${node} ${parentDirectory}
                ;;
esac
echo "$@脚本执行完毕"

服务重启脚本

#!/bin/bash
project="$2"  # 项目名字 testwechat

jarname="$4"
echo $jarname
APP_NAME=${appName}
#packageName=20200616_144104WeChat.jar   #打包的名字
APP_NAME=${appName%.*} #把jar去掉
APP_NAME=${APP_NAME:15} #只保留WeChat这个名字
PROJECT=${project}


APP_DIR=/home/spring_boot/${PROJECT} # 项目路径
JAR_NAME=${appName} # jar包路径
java="/usr/bin/java"
# 自定义
logPath=/data/log/$project
#echo "11111111111"+ $logPath

if [ ! -x "$logPath" ]; then
        mkdir -p "${logPath}"
fi
envName=test

case "$1" in
        start)
                #nohup java -jar $APP_DIR/$JAR_NAME --logging.path=$logPath >$logPath/nohup.out 2>&1 &
                #echo "开始启动服务"
            
                 nohup $java -jar $APP_DIR/$appName --spring.profiles.active=$envName > $logPath/nohup.log &
                #su ops -c " nohup java -jar $APP_DIR/$appName > $APP_DIR/nohup.log &" 
                sleep 17
                echo "查看启动日志......."
                grep -r JVM $logPath/nohup.log
                #tail -n20 $APP_DIR/nohup.log 
                echo "查看启动进程"
                sleep 5
                #/usr/bin/ps -ef |grep $jarname|grep -v grep
                ps -ef |grep $appName|grep -v grep|grep java
                #echo "start $APP_NAME success!"
                ;;
        stop)
                


                APP_PID=`ps -ef|grep $jarname|grep $APP_DIR|grep -v 'grep'|awk '{print $2}'`
                # APP_PID=`ps -ef|grep $jarname|grep -v 'grep'|awk '{print $2}'`
                echo ${APP_PID}
                #kill -9 $APP_PID
                #exit 
                if [ "$APP_PID" == "" ];
                then
                        echo "已经停止"
                        #exit
                else
                       # echo "$APP_NAME process pid is:$APP_PID"

                fi

                ;;
        restart)
                echo "restarting $APP_NAME"
                /usr/local/tiantian_dubbo/server.sh stop $2
                echo "stoped"
                sleep 2
                echo "starting"
                /usr/local/tiantian_dubbo/server.sh start $2
                ;;
        *)
                echo "start|restart|stop"
                ;;
esac
exit 0

最后保存，执行即可

二 利用端口查找pid

1 设置项目和要回滚的主机

2 设置jar包名称和端口

3 回滚脚本

node() {


stage("rollback"){
    sh '''
     /jenkins_shell/rollback_port.sh  $appname $host $jarname $project_port
    '''

}


}

4 主脚本内容：

#!/bin/bash
function sendToRemote(){
        currentTime=`date "+%Y%m%d_%H%M%S"`
        remote_shell_path=/home/spring_boot
        remote_path=/home/spring_boot/${project}
        #echo $remote_path
        remote_backup_path=${remote_path}/backup
        file_name=`ssh ${remote_user}@${remote_ip} -p${remote_port} "ls -t  ${remote_backup_path} |head -1"` #最新的备份文件
        echo "开始关闭服务"
        
        ssh ${remote_user}@${remote_ip} -p${remote_port} "/bin/sh ${remote_shell_path}/aliay_server.sh stop ${project} ${currentTime}${jarname} ${project_port}"  
       #ssh ${remote_user}@${remote_ip} -p${remote_port} "/bin/sh ${remote_shell_path}/server.sh stop ${jarname}.jar" && sleep 2
        #stop=`ssh ${remote_user}@${remote_ip} -p${remote_port} "ps -ef |grep ${project}|grep -v grep |wc -l"`
        #if [ ${stop} -eq 0 ];then

         # echo "关闭完成"
          #删除有问题的软件包
        ssh ${remote_user}@${remote_ip} -p${remote_port} "rm -rf ${remote_path}/20*"
        #else
         # echo "关闭失败"
          #exit
        #fi

        echo "关闭完成"
        echo "正在拷贝回滚文件"
        ssh ${remote_user}@${remote_ip} -p${remote_port} "cp -r ${remote_backup_path}/${file_name} ${remote_path}"
        echo "恢复完成"
        sleep 5
        echo "开始启动服务"
        ssh ${remote_user}@${remote_ip} -p${remote_port} "/bin/sh ${remote_shell_path}/aliay_server.sh start ${project} ${file_name}" && sleep 2
      
        #job=`ssh ${remote_user}@${remote_ip} -p${remote_port} "ps -ef |grep ${project}|grep -v grep |wc -l"`
        #if [ ${job} -eq 1 ];then

         # echo "启动完成"
        #else
         # echo "启动失败"
          #exit
       # fi
}
function remote(){
        project=$1
        jarname=$2
        parentDirectory=$4
        remote_port=22
        remote_user=root
        remote_ip=$3
        echo "remote_ip:${remote_ip}"
        local_dir=/home/yw/git_project
        sendToRemote
}

case   "$@" in
        *)
                packageName="$1"
                parentDirectory="$3"
                node="$2"
                project_port="$4"
                remote ${packageName%.*} ${packageName} ${node} ${parentDirectory}
                ;;
esac
echo "$@脚本执行完毕"

5 启动和关闭服务的脚本如下;

#!/bin/bash
project="$2"  # 项目名字 testwechat

port="$4"
echo $jarname

#packageName=20200616_144104WeChat.jar   #打包的名字
APP_NAME=${appName%.*} #把jar去掉
APP_NAME=${APP_NAME:15} #只保留WeChat这个名字
PROJECT=${project}


APP_DIR=/home/spring_boot/${PROJECT} # 项目路径
JAR_NAME=${appName} # jar包路径
java="/usr/bin/java"
# 自定义
logPath=/data/log/$project
#echo "11111111111"+ $logPath

if [ ! -x "$logPath" ]; then
        mkdir -p "${logPath}"
fi
envName=test

case "$1" in
        start)
                #nohup java -jar $APP_DIR/$JAR_NAME --logging.path=$logPath >$logPath/nohup.out 2>&1 &
                #echo "开始启动服务"
            
                 nohup $java -jar $APP_DIR/$appName --spring.profiles.active=$envName > $logPath/nohup.log &
                #su ops -c " nohup java -jar $APP_DIR/$appName > $APP_DIR/nohup.log &" 
                sleep 17
                echo "查看启动日志......."
                grep -r JVM $logPath/nohup.log
                #tail -n20 $APP_DIR/nohup.log 
                echo "查看启动进程"
                sleep 5
                #/usr/bin/ps -ef |grep $jarname|grep -v grep
                ps -ef |grep $appName|grep -v grep|grep java
                #echo "start $APP_NAME success!"
                ;;
        stop)
                pid=$(netstat -nlp | grep :$port | awk '{print $7}' | awk -F"/" '{ print $1 }'); #判断进程是否存在
                echo $pid
                if [  -n "$pid" ]; #变量的值非空返回0 
                    then kill -9 $pid;
                    echo "关闭服务成功"
                else
                    echo "服务并没有启动"
                fi




                ;;
        restart)
                echo "restarting $APP_NAME"
                /usr/local/tiantian_dubbo/server.sh stop $2
                echo "stoped"
                sleep 2
                echo "starting"
                /usr/local/tiantian_dubbo/server.sh start $2
                ;;
        *)
                echo "start|restart|stop"
                ;;
esac
exit 0

最后执行即可
