查看nginx的版本：

nginx -v

nginx version: nginx/1.14.0 (Ubuntu)

如果您正在运行防火墙，则还需要打开端口80和443。

sudo ufw allow 'Nginx Full'

以下方式验证更改：

ufw status
[sudo] linuxidc 的密码：

输出：

状态： 激活

至                          动作          来自
-                          --          --
Nginx Full                ALLOW      Anywhere                 
Nginx Full (v6)            ALLOW      Anywhere (v6)       

此时在浏览器中输入IP地址比如本地IP地址localhost。看到页面如下，表示Nginx已经启动成功

你可以像任何其他systemd单位一样管理Nginx服务。 要停止Nginx服务，请运行：

sudo systemctl stop nginx

要再次启动，请键入：

sudo systemctl start nginx

sudo systemctl restart nginx

$sudo systemctl disable nginx

$sudo systemctl enable nginx
