Linux项目开机启动脚本

cd  /usr/lib/systemd/system

vim cloud.service

#!/bin/bash
[Unit]
Description=cloud-service
after=syslog.target network.target

[Service]
ExecStart=/bin/sh /usr/local/project/cloud/cloud.sh start
ExecReload=/bin/sh /usr/local/project/cloud/cloud.sh restart
ExecStop=/bin/sh /usr/local/project/cloud/cloud.sh stop
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

注意，这样之后，上边的jar包也要稍微改一下：

chmod +x cloud.service

加载新的unit 配置文件

systemctl daemon-reload

开启服务自启动

systemctl enable cloud.service

关闭服务自启动

systemctl disable cloud.service

查找某个服务

 systemctl list-unit-files | grep firewalld
