jenkins发布项目

一 前提

1 首先要保证你的jenkins服务器可以正常连接你要发布的服务器，所以可以设置下免密钥登录，并且注意你的jenkins用户，到对方的机器是否有执行权限，比如重启服务，备份等。
2 设置hosts,如果用主机名通信的话。

二 jenkins设置

1 选择要发布的项目

2 选择要发布的主机

3 选择父目录

一个项目，可能里面包括很多子项目，如果你要发布的子项目，就需要先选择父母录

4 执行发布脚本

三 脚本编写

1 拷贝新包，和备份旧包

sendPort.sh脚本

#!/bin/bash
function sendToRemote(){
        currentTime=`date "+%Y%m%d_%H%M%S"`
        remote_shell_path=/usr/local/tiantian_dubbo #远端服务器项目目录
        remote_path=/usr/local/tiantian_dubbo/${project}
        local_package=${local_dir}/${parentDirectory}/${project}/target/${package_name}
	echo "local_package::"${local_package}
        remote_wait_package=${remote_path}/wait/${currentTime}${package_name}
	remote_backup_path=${remote_path}/backup
        echo "发送到远程服务器"
	scp -P${remote_port} ${local_package} ${remote_user}@${remote_ip}:${remote_wait_package}
	echo "开始关闭服务"
        ssh ${remote_user}@${remote_ip} -p${remote_port} "/bin/sh ${remote_shell_path}/server.sh stop ${currentTime}${package_name}" && sleep 2
        echo "关闭完成"
	echo "开始执行备份"
        ssh ${remote_user}@${remote_ip} -p${remote_port} "mv ${remote_path}/*${package_name} ${remote_backup_path}/"
	echo "备份完成"
	echo "将等待执行文件mv到执行目录"
        ssh ${remote_user}@${remote_ip} -p${remote_port} "mv ${remote_wait_package} ${remote_path}/"
        echo "mv完成"
	echo "开始启动服务"
        ssh ${remote_user}@${remote_ip} -p${remote_port} "/bin/sh ${remote_shell_path}/server.sh start ${currentTime}${package_name}"
	echo "启动完成"
}
function remote(){
        project=$1
        package_name=$2
        parentDirectory=$4
        remote_port=51212
        remote_user=jenkins
        remote_ip=$3
	    echo "remote_ip:${remote_ip}"
        local_dir=/xs/git_project/tiantian_dubbo
        sendToRemote
}

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

2 启动服务脚本

server.sh

# description: app开机启动脚本
# 接收入参带.jar的待启动包名称
packageName="$2"

RETVAL=0
APP_NAME=${packageName%.*}
APP_NAME=${APP_NAME:15}
# description: app开机启动脚本

# 接收入参带.jar的待启动包名称
packageName="$2"

RETVAL=0
APP_NAME=${packageName%.*}
APP_NAME=${APP_NAME:15}
export JAVA_HOME=/usr/local/java/jdk1.8.0_111
export JRE_HOME=/usr/local/java/jdk1.8.0_111/jre

APP_DIR=/usr/local/tiantian_dubbo/${APP_NAME}
JAR_NAME=${packageName}
PID=$APP_NAME\.pid
# 自定义
logPath=/datalog/service/$APP_NAME/$server_name

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

# 运行环境------------------------------必须要指定
envName=prod

cd $APP_DIR
case "$1" in
        start)

                nohup $JRE_HOME/bin/java -Dfile.encoding=utf-8 ${java_opts} -jar $APP_DIR/$JAR_NAME --spring.profiles.active=$envName --logging.path=$logPath >$logPath/nohup.out  2>&1 &
                echo $! > $APP_DIR/$PID
                echo "start $APP_NAME success!"
                ;;
        stop)
                kill -9 `cat $APP_DIR/$PID`
                echo "begin stop $APP_NAME"
                sleep 5
                APP_PID=`ps -ef|grep $$APP_NAME|grep $APP_DIR|grep -v 'grep'|awk '{print $2}'`
                if [ "$APP_PID" == "" ];
                then
                        echo "stop $APP_NAME success !"
                else
                        echo "$APP_NAME process pid is:$APP_PID"
                        echo "begin kill $APP_NAME process, pid is:$APP_PID"
                        kill -9 $APP_PID
                        echo "stop $APP_NAME success!"
                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
