Question

我正在尝试通过nginx在Amazon AWS EC2 Ubuntu 18.04上托管网站。我首先关注this tutorial。我跑了sudo apt update和sudo apt install nginx。然后，我运行了sudo ufw allow 'Nginx HTTP'。运行sudo ufw status返回了以下内容；

Status: active

To                         Action      From
--                         ------      ----
Nginx HTTP                 ALLOW       Anywhere
OpenSSH                    ALLOW       Anywhere
Nginx HTTP (v6)            ALLOW       Anywhere (v6)
OpenSSH (v6)               ALLOW       Anywhere (v6)

此后，我运行systemctl status nginx并返回：

   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: en
   Active: active (running) since Thu 2019-03-21 14:30:31 UTC; 1min 17s ago

Mar 21 14:30:31 ip-172-31-29-16 systemd[1]: Started A high performance web server and a reverse proxy server.

然后我尝试解决Failed to parse PID from file /run/nginx.pid: Invalid argument错误。我是这样做的，先做mkdir /etc/systemd/system/nginx.service.d，然后再做printf "[Service]\nExecStartPost=/bin/sleep 0.1\n"，

[服务]
ExecStartPost = / bin / sleep 0.1

此后，我运行sudo nano /etc/systemd/system/nginx.service.d/override.conf，并将上面的引号插入其中并保存。然后sudo systemctl daemon-reload和sudo systemctl restart nginx。之后，运行systemctl status nginx返回了此信息：

● nginx.service - A high performance web server and a reverse proxy server

我认为现在一切正常，所以我运行了curl localhost并且返回了

<!DOCTYPE html>

    body {
        width: 35em;
        margin: 0 auto;

    }

<body>

我相信我也应该能够从家用PC上访问它，所以我做了curl ifconfig.me来获取我的公共IP，然后我去了http://PUBLICIP，但是它说这个站点不能达到。

有人可以帮我解决这个问题吗？

谢谢。

Answer 1

问题是我的AWS安全组，我添加了一个入站规则来接受所有TCP，现在它可以工作了。

Ubuntu 18上的nginx网站未在公共IP上加载
