Question

我是一个关于设置生产机器的新人，我不知道为什么我没有在我的EC2机器上看到nginx的默认索引页面。它已在我的服务器上安装并运行，但是当我尝试访问时，它会继续加载并且不显示任何内容，保持在空白页面上。我试图通过公共IP（35.160.22.104）和公共dns（ec2-35-160-22-104.us-west-2.compute.amazonaws.com）访问。两者都是一样的。我做错了什么？

更新：我意识到重启nginx服务时，它没有显示“ok”消息。所以我看了一下error.log：

[ 2016-12-12 17:16:11.2439 709/7f3eebc93780 age/Cor/CoreMain.cpp:967 ]: Passenger core shutdown finished

无论如何，它看起来不像是错误，而是通常的日志。

更新2： Nginx正在运行：

root       810     1  0 17:16 ?        00:00:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
www-data   815   810  0 17:16 ?        00:00:00 nginx: worker process
ubuntu     853 32300  0 17:44 pts/0    00:00:00 grep --color=auto nginx

当我尝试curl localhost时，它会按预期返回HTML！

UPDATE3：

当我运行systemctl status nginx时，我收到以下错误：

Dec 12 17:54:48 ip-172-31-40-156 systemd[1]: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument

试图找出它是什么

UPDATE4：执行命令nmap 35.160.22.104 -Pn PORT STATE SERVICE 22/tcp并获得输出：

Starting Nmap 7.01 ( https://nmap.org ) at 2016-12-12 18:05 UTC

UPDATE5：

netstat -tuanp | grep 80的输出：

Answer 1

您的ec2实例已关联安全组。您应该转到AWS控制台EC2 - ＆gt;实例 - ＆gt;点击您的实例 - ＆gt;在底部'描述' - ＆gt;安全组。点击名称，您将重定向到EC2-＆gt;网络与安全。点击“编辑入站规则”添加规则：

类型：HTTP

保存。这应该没事！

NGINX亚马逊EC2继续加载但没有显示任何内容
