Linux中jar包快捷启动、停止、jar包后台运行和 jar包开机自启动 的实现方式

开机自动执行命令：

注：将/usr/local/project/access/access.jar设置为快捷启动和自启动

一、设置启动连接

在``/usr/local/project/access/access/bin`目录下新建启动脚本和停止脚步

1. 新建一个启动脚本access-service-start.sh

   #!/bin/sh
   
   #java默认放在/usr/local/soft/jdk1.8.0_251
   JAVA_HOME=/usr/local/soft/jdk1.8.0_251
   PATH=$JAVA_HOME/bin:$PATH
   export JAVA_HOME PATH
   
   # 设置jar的启动位置，并且将日志打印到jar的根目录中的access.log文件中
   nohup java -jar /usr/local/project/access/access.jar >/usr/local/project/access/access.log 2>&1 &
   
   #获取PID
   echo $! > /usr/local/project/access/access.pid
   

2. 新建一个停止脚步access-service-stop.sh

   #!/bin/sh
     
   PID=$(cat /usr/local/project/access/access.pid)
   
   kill -9 $PID
   

在/usr/lib/systemd/system目录新建系统启动或开机启动脚步access.service

#!/bin/sh
  
[Unit]
Description=access

After=syslog.target network.target remote-fs.target nss-lookup.target


[Service]
Type=forking

#核心部分
ExecStart=/usr/local/project/access/lib/access-service-start.sh
ExecStop=/usr/local/project/access/lib/access-service-stop.sh
PrivateTmp=true


[Install]
WantedBy=multi-user.target

二、给启动、停止脚本设置权限

chmod +x /usr/local/project/access/access-service-start.sh

chmod +x /usr/local/project/access/access-service-stop.sh

三、设置完成，常用命令：

systemctl start access		//启动jar

systemctl status access		//查看运行状态

systemctl stop access		//停止jar运行

systemctl enable access		//设置为开机自启动 

systemctl disable access	//禁止开机启动

tail -f access.log		//动态查询日志文件
