切换到/lib/systemd/system/目录，创建nginx.service文件vim nginx.service
cd /lib/systemd/system/
vim nginx.service

退出并保存文件，执行systemctl enable nginx.service使nginx开机启动
systemctl enable nginx.service
systemctl start nginx.service 启动nginx
systemctl stop nginx.service 结束nginx
systemctl restart nginx.service 重启nginx
