常見的linux上的服務重啟腳本

手寫linux上的重啟腳本，先把提綱列下

1.檢查進程是否存在

存在殺死

2.備份原來的包到指定目錄

3. 拉取新包，我這邊為了簡便，沒有從jenkins slave上拿

4.啟動命令

5.檢查是否進程起來了

 

#!/bin/bash

###path
JAVA=/usr/java/jdk1.8.0_211-amd64/bin/java
APP_HOME=/opt/88bugs
APPNAME=TestPlatform.jar
APP_PARAM="--spring.config.location=${APP_HOME}/application.properties"


####check wheather the port is running, if yes kill it
PID=`ps -ef | grep ${APP_HOME}/${APPNAME} | grep -v grep | awk '{print $2}'`
echo ${PID}

if test -z ${PID}
then 
	echo "進程沒有啟動！"

else 
	echo "will shutdown this process"
	kill -9 ${PID}
	sleep 2
fi


####backuop
mv ${APP_HOME}/${APPNAME} ${APP_HOME}/backup/${APPNAME}-date +%Y%m%d%H%M%S

####deploy the war package
cp -r /opt/${APPNAME}  ${APP_HOME}/${APPNAME}


##### start the process#
nohup ${JAVA} -jar ${APP_HOME}/${APPNAME} ${APP_PARAM}  > ${APP_HOME}/catalina.out 2>&1  &

afterPID=`ps -ef | grep ${APP_HOME}/${APPNAME} | grep -v grep | awk '{print $2}'`
echo ${afterPID}
sleep 10

if test -z ${afterPID}
then
	echo "部署失敗"
else 
	echo "部署成功"
fi

 

若腳本希望既可以停止服務，又可以重啟服務，

那么結構屢一下

配置環境，可供其他項目更改細節使用

獲取輸入，條件如果輸入的是a，則執行a的方法；如果是b則執行b的方法體，什么都不是，即不是指定的指令，輸出提示“您輸入的指令沒有對應的方法喲”

在上面的腳本上，更改些許即可
