一、开机启动服务的配置
1.创建服务配置(权限754)
vim /usr/lib/systemd/system/nginx.service
文件内容解释
[Unit]:服务的说明
Description:描述服务After:描述服务类别[Service]服务运行参数的设置
Type=forking是后台运行的形式ExecStart为服务的具体运行命令ExecReload为重启命令ExecStop为停止命令PrivateTmp=True表示给服务分配独立的临时空间注意：启动、重启、停止命令全部要求使用绝对路径[Install]服务安装的相关设置，可设置为多用户
以754的权限保存服务配置！！！
2.设置开机自启动
任意目录下执行::systemctl enable nginx.service
二、开机启动服务的管理
- 启动nginx服务 systemctl start nginx.service
- 设置开机自启动 systemctl enable nginx.service
- 停止开机自启动 systemctl disable nginx.service
- 查看服务当前状态 systemctl status nginx.service
- 重新启动服务 systemctl restart nginx.service
- 查看所有已启动的服务 systemctl list-units --type=service
