1、關閉當前nginx運行

systemctl stop nginx

2、添加以下內容到nginx.service文件，注意nginx.pid文件的路徑，要替換哦！

vim /etc/systemd/system/nginx.service

[Unit]
Description=The NGINX HTTP and reverse proxy server
After=network.target[Service]
Type=forking
PIDFile=/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t
ExecStart=/usr/sbin/nginx
ExecReload=/usr/sbin/nginx -s reload
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true[Install]
WantedBy=multi-user.target

3、重新加載systemd管理器配置

sudo systemctl daemon-reload

4、啟用nginx開機自啟

systemctl enable nginx

5、關機重啟機器

shutdown -r now

6、后續需要關掉開機自啟

systemctl disable nginx
