一. 关于systemctl的基本命令参考：http://www.ruanyifeng.com/blog/2016/03/systemd-tutorial-part-two.html

二. 写service配置，两种方式：设定working目录,springboot会在working目录下寻找application.yml加载；不设定working目录，指定springboot配置文件
2.1 设定working目录：

vi /lib/systemd/system/test.service

[Unit]Description=test [Service]WorkingDirectory=/usr/local/testPrivateTmp=trueRestart=alwaysType=simpleExecStart=/usr/local/java/jdk1.8.0_101/bin/java -jar /usr/local/test/test.jarExecStop=/usr/bin/kill -15  $MAINPID[Install]WantedBy=multi-user.target

2.2 指定springboot配置文件目录

[Unit]Description=test [Service]WorkingDirectory=/usr/local/testPrivateTmp=trueRestart=alwaysType=simpleExecStart=/usr/local/java/jdk1.8.0_101/bin/java -jar /usr/local/test/test.jar --spring.config.location=/usr/local/test/application.ymlExecStop=/usr/bin/kill -15  $MAINPID[Install]WantedBy=multi-user.target

三. systemctl 管理，让配置生效。若是修改配置文件，需要reload：

sudo systemctl daemon-reload

sudo systemctl enable test.service

启动服务

systemctl start test
