linux启动带 sh脚本,linux系统软件启动sh脚本

在系统维护中，编写脚本会帮助运维提高效率，现记录一个通用的软件启动脚本。脚本内容如下：

#!/bin/bash

# 软件启动程序包名称

APP_NAME=datadog-4.2.0.jar

# 软件名称

APP_NAME2=Datadog

usage() {

echo "Usage: sh 执行脚本.sh [start|stop|restart|status]"

exit 1

}

is_exist(){

pid=`ps -ef|grep $APP_NAME|grep -v grep|awk '{print $2}' `

if [ -z "${pid}" ]; then

return 1

else

return 0

fi

}

# 启动

start(){

is_exist

if [ $? -eq "0" ]; then

echo "${APP_NAME2} is already running. pid=${pid} ."

else

nohup jre/bin/java -jar $APP_NAME >> run.log 2>&1 &

fi

}

# 停止

stop(){

is_exist

if [ $? -eq "0" ]; then

kill -9 $pid

else

echo "${APP_NAME2} is not running"

fi

}

# 查看软件运行状态

status(){

is_exist

if [ $? -eq "0" ]; then

echo "${APP_NAME2} is running. pid is ${pid}"

else

echo "${APP_NAME2} is not running."

fi

}

# 重启，先停止再启动

restart(){

stop

start

}

case "$1" in

"start")

start

;;

"stop")

stop

;;

"status")

status

;;

"restart")

restart

;;
