从外部浏览器访问我的 AWS EC2 服务器 index.html
[英]Access my AWS EC2 server index.html from external browser
问题描述
I've been setting up an AWS EC2 server this week, and I'm almost there with what I want to do.
这周我一直在设置 AWS EC2 服务器，我几乎已经完成了我想做的事情。 But opening up as a web server is proving to be a stumbling block.但事实证明，作为 Web 服务器开放是一个绊脚石。
MY SETUP我的设置
I have an AWS EC2 instance running Red Hat EL7.我有一个运行 Red Hat EL7 的 AWS EC2 实例。
I have an Apache server running on my instance:我的实例上运行着一个 Apache 服务器：
[ec2-user@ip-172-xx-xx-xx ~]$ ps -ef | grep -i httpd
root 18162 1 0 18:02 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND
apache 18163 18162 0 18:02 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND
apache 18164 18162 0 18:02 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND
apache 18165 18162 0 18:02 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND
apache 18166 18162 0 18:02 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND
apache 18167 18162 0 18:02 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND
ec2-user 21345 20507 0 19:03 pts/1 00:00:00 grep --color=auto -i httpd
It seems to be listening on port 80:它似乎在监听 80 端口：
[root@ip-172-xx-xx-xx ~]# netstat -lntp | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 18162/httpd
I added inbound rules to the "launch-wizard-1" security group (which is shown as the security group for the instance) for port 80 (HTTP) and 443 (HTTPS) with sources of "0.0.0.0/0" and "::/0"我将入站规则添加到端口 80 (HTTP) 和 443 (HTTPS) 的“launch-wizard-1”安全组（显示为实例的安全组），来源为“0.0.0.0/0”和“ ::/0"
And finally, for testing my setup, I created an index.html file in my document root (/var/www/html):最后，为了测试我的设置，我在文档根目录 (/var/www/html) 中创建了一个 index.html 文件：
<html>
<h1>TEST!</h1>
</html>
THE PROBLEM问题
From my chrome browser on my computer, when I try to hit:从我电脑上的 chrome 浏览器中，当我尝试点击：
http://ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com/index.html http://ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com/index.html
I just get:我只是得到：
This page isn’t working
ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com didn’t send any data.
ERR_EMPTY_RESPONSE
(I get the same when I hit one of my domain names which I've set up on there, which is what I'm really trying to do of course!) （当我点击我在那里设置的一个域名时，我得到了同样的结果，这当然是我真正想要做的！）
I've tried connecting from Chrome on 2 different computers, and from Safari on my phone ("Safari cannot open the page because it could not connect to the server")我试过从 2 台不同计算机上的 Chrome 连接，以及从我手机上的 Safari 连接（“Safari 无法打开页面，因为它无法连接到服务器”）
CHECKS I'VE PERFORMED我做过的检查
I don't believe I have any server firewall preventing this:我不相信我有任何服务器防火墙阻止这种情况：
[root@ip-xx-xx-xx-xx conf]# /sbin/iptables -L -v -n
Chain INPUT (policy ACCEPT 3575 packets, 275K bytes)
pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 2215 packets, 350K bytes)
pkts bytes target prot opt in out source destination
Testing with telnet from a terminal session on my mac, port 80 appears to be open.从我的 mac 上的终端会话使用 telnet 进行测试，端口 80 似乎是打开的。 Firstly using the IPv2 Public IP:首先使用 IPv2 公共 IP：
telnet 18.xxx.xxx.xx 80
Trying 18.xxx.xxx.xx...
Connected to ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com.
Escape character is '^]'.
Connection closed by foreign host.
and using the Public DNS (IPv4):并使用公共 DNS (IPv4)：
telnet ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com 80
Trying 18.xxx.xxx.xx...
Connected to ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com.
Escape character is '^]'.
Connection closed by foreign host.
And again, the same goes for my domain names - telnet to port 80 shows "Connected".同样，我的域名也是如此——telnet 到端口 80 显示“已连接”。
- Is the fact that the "foreign host" closes the connection immediately significant? - “外国主机”立即关闭连接这一事实是否重要？ Should it stay open if everything is working as it should?如果一切正常，它是否应该保持开放状态？
Running curl on the host correctly returns my simple index.html file:在主机上正确运行 curl 会返回我的简单 index.html 文件：
[ec2-user@ip-172-xx-xx-xx ~]$ curl localhost
<html>
<h1>TEST!</h1>
</html>
However, running a curl on my local computer - to the server - returns:但是，在我的本地计算机上运行 curl - 到服务器 - 返回：
curl -v http://ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com:80
* Rebuilt URL to: http://ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com:80/
* Trying 18.xxx.xxx.xx...
* Connected to ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com (18.xxx.xxx.xx) port 80 (#0)
> GET / HTTP/1.1
> Host: ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com
> User-Agent: curl/7.43.0
> Accept: */*
>
* Empty reply from server
* Connection #0 to host ec2-18-xxx-xxx-xx.us-east-2.compute.amazonaws.com left intact
curl: (52) Empty reply from server
I also tested the webserver "internally" by running google chrome (headless) on the server to create a screenshot, downloaded to my local computer and it shows TEST.我还通过在服务器上运行 google chrome（无头）来“内部”测试网络服务器以创建屏幕截图，下载到我的本地计算机并显示 TEST。 (ie: its working): （即：它的工作原理）：
google-chrome-stable --headless --disable-gpu --screenshot http://localhost
One more thing to add - when I attempt the hit the webserver from my local machine, nothing shows in the webserver logs (error_log or access_log) on the server.要添加的另一件事 - 当我尝试从本地计算机访问网络服务器时，服务器上的网络服务器日志（error_log 或 access_log）中没有显示任何内容。
So, my opinion is that the web server is up and running, works locally, but is not working correctly for anything coming from "outside".因此，我的意见是 Web 服务器已启动并正在运行，在本地工作，但对于来自“外部”的任何内容都无法正常工作。 I'm stumped now though.不过我现在很困惑。

Doh.呵呵。 I rebooted the instance and.. all working now!我重新启动了实例并且......现在一切正常！
22 years working with computers and it took me 22 hrs to resort to a reboot.使用计算机 22 年，我花了 22 小时才重新启动。 Fool!傻子！

- Connect to your

pythonif not installed如果没有安装python，请安装 Start a python server using
nohupto continuously use the server使用nohup启动 python 服务器以持续使用服务器nohup python -m http.server &This usually open port
8000, gotoEC2 Security GroupMake sourceanywhereor as needed.这通常打开端口8000，转到EC2 Security Group在anywhere或根据需要制作源代码。
Navigate to the folder having
