在linux下,把程序设置systemctl服务,并开机启动

以nexus服务为例:

进入/usr/lib/systemd/system, 新建nexus.service文件,写入如下内容, 字段说明请百度systemctl服务的字段说明

[Unit]
Description=Nexus
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
Environment="JAVA_HOME=/usr/java/jdk1.8.0_144"
ExecStart=/usr/local/nexus/nexus-3.7.1-02/bin/nexus start
ExecStop=/usr/local/nexus/nexus-3.7.1-02/bin/nexus stop
[Install]
WantedBy=multi-user.target

保存退出,

输入

systemctl reload *.service #重新加载服务配置文件

然后就可以启动服务了, systemctl start nexus.service即可

设置开机启动: systemctl enable nexus.service

systemctl常见命令:

systemctl is-enabled servicename.service #查询服务是否开机启动
systemctl enable *.service #开机运行服务
systemctl disable *.service #取消开机运行
systemctl start *.service #启动服务
systemctl stop *.service #停止服务
systemctl restart *.service #重启服务
systemctl reload *.service #重新加载服务配置文件
systemctl status *.service #查询服务运行状态
systemctl --failed #显示启动失败的服务
