java jar 自启动 centos7 systemctl

  我本地有一个 data-service.jar

1. 编写启动脚本  data-service-start

[root@iz2ze0fq2isg8vphkpos5sz shell]# more  data-service-start  
#!/bin/sh  
  
export JAVA_HOME=/usr/local/jdk1.8.0_131  
export PATH=$JAVA_HOME/bin:$PATH  
  
java -jar /data/imgcloud/data-service.jar > /data/logs/data-service.log &  
echo $! > /var/run/data-service.pid  

2. 编写停止脚本

[root@iz2ze0fq2isg8vphkpos5sz shell]# more data-service-stop   
#!/bin/sh  
PID=$(cat /var/run/data-service.pid)  
kill -9 $PID  

3. 在/usr/lib/systemd/system 下 编写 data-service.service 脚本

[root@iz2ze0fq2isg8vphkpos5sz shell]# cd /usr/lib/systemd/system  
[root@iz2ze0fq2isg8vphkpos5sz system]# more data-service.service   
[Unit]  
Description=data-service for mongodb  
After=syslog.target network.target remote-fs.target nss-lookup.target  
   
[Service]

ExecStart=/data/shell/data-service-start  
ExecStop=/data/shell/data-service-stop  
PrivateTmp=true  
   
[Install]  
WantedBy=multi-user.target  

　　

 

4. 相关命令

systemctl  stop  data-service  停止

system  start data-service  启动
