问题描述
我正在尝试通过nginx在Amazon AWS EC2 Ubuntu 18.04上托管网站.我首先阅读了本教程.我运行了 sudo apt update 和 sudo apt install nginx .然后，我运行了 sudo ufw allow'Nginx HTTP'.运行 sudo ufw status 会返回以下内容；
I am trying to host a website via nginx on Amazon AWS EC2 Ubuntu 18.04. I started by following this tutorial. I ran sudo apt update and sudo apt install nginx. Then, I ran sudo ufw allow 'Nginx HTTP'. Running sudo ufw status returned the following;
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，我运行了 systemctl status nginx 并返回:
After that I ran systemctl status nginx which returned:

然后，我尝试修复无法从文件/run/nginx.pid解析PID:无效参数错误.我这样做是通过 mkdir/etc/systemd/system/nginx.service.d ，然后是 printf"[Service] \ nExecStartPost =/bin/sleep 0.1 \ n" 回来了
I then tried to fix the Failed to parse PID from file /run/nginx.pid: Invalid argument error. I did that by doing mkdir /etc/systemd/system/nginx.service.d, then printf "[Service]\nExecStartPost=/bin/sleep 0.1\n" which returned
[服务]
ExecStartPost =/bin/sleep 0.1
[Service]
ExecStartPost=/bin/sleep 0.1
此后，我运行了 sudo nano/etc/systemd/system/nginx.service.d/override.conf 并将上面的引号插入其中并保存了.然后 sudo systemctl daemon-reload 和 sudo systemctl重新启动nginx .在运行 systemctl status nginx 后返回以下代码:
After that I ran sudo nano /etc/systemd/system/nginx.service.d/override.conf and inserted the above quote into there and saved it. Then sudo systemctl daemon-reload and sudo systemctl restart nginx. After that running systemctl status nginx returned this:

我认为现在一切都应该正常工作，所以我运行了 curl localhost 并且返回了
I figured everything should be working now, so I ran curl localhost and that returned

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
I believe I should also be able to access this from my home PC, so I did curl ifconfig.me to get my public IP and then I went to http://PUBLICIP, but it said This site can’t be reached.
有人可以帮我解决这个问题吗?
Can someone help me fix this please?
谢谢.
推荐答案
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.
Problem was my AWS security groups, I added an inbound rule to accept all TCP and now it works.
