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]

[Service]

ExecStart=/data/shell/data-service-start
ExecStop=/data/shell/data-service-stop

[Install]
