shell脚本启动jar包 一、脚本

1. 通过 true或false控制是否启动

#!/bin/sh
export common_service_enable=true
export business_service_enable=true
export xiaopandian_web_enable=true
 
export common_service=/mnt/xiaopandian-api/dev-common-service.jar
export business_service=/mnt/xiaopandian-api/dev-business-service.jar
export xiaopandian_web=/mnt/xiaopandian-api/dev-xiaopandian-web.jar

export common_service_port=17001
export business_service_port=17002
export xiaopandian_web_port=17003

	## 杀掉common_service
        P_ID=`ps -ef | grep -w ${common_service##*/} | grep -v "grep" | awk '{print $2}'`
        if [ "$P_ID" == "" ]; then
            echo "===common_service process not exists or stop success"
        else
            kill -9 $P_ID

        sleep 2
        $0 start
        echo "===restartAll success==="
        ;;

	## 检查common_service
	P_ID=`ps -ef | grep -w ${common_service##*/} | grep -v "grep" | awk '{print $2}'`
        if [ "$P_ID" == "" ]; then

二、过程

1. 将.sh脚本拖到服务器

2. 将.sh文件赋予权限

   chmod 775 XXX.sh

3. 执行

   # 启动
   ./XXX.sh start 
   # 停止
   ./XXX.sh stop
   # 检查
   ./XXX.sh check
   # 重启
   ./XXX.sh restart

三、问题

1. Linux执行.sh文件，提示No such file or directory的问题

   • 原因：在windows中写好shell脚本测试正常，但是上传到 Linux 上以脚本方式运行命令时提示No such file or directory错误，那么一般是文件格式是dos格式的缘故，改成unix 格式即可。一般有如下几种修改办法。

   • 解决办法：

     用vim打开该sh文件，输入：
     :set ff 
     回车，显示fileformat=dos，重新设置下文件格式：
     :set ff=unix 
     保存退出: 
     :wq 
     再执行，竟然可以了

2. 解决Ubuntu下编译.sh文件报错 “[: XXXX: unexpected operator”

   • 原因：因为Ubuntu默认的sh是连接到dash的，dash跟bash的不兼容所以出错了。

   • 解决办法：命令行输入后，选择NO

     sudo dpkg-reconfigure dash
