在ec2亚马逊实例上的ubuntu服务器上安装了指示灯，但仍无法通过运行Apache的浏览器访问服务器。 为什么？

Question

I started an instance on amazon ec2, ami is ubuntu 14.04. I followed the steps on https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html exactly up until "Transferring Files to Your Linux Instance Using the PuTTY Secure Copy Client" Since I don't need to put files on there just yet. Then I followed the following: https://help.ubuntu.com/community/ApacheMySQLPHP .

"To install the default LAMP stack in Ubuntu 10.04 and above First refresh your package index...

$ sudo apt-get update

... and then install the LAMP stack:

$ sudo apt-get install lamp-server^

Mind the caret (^) at the end. "

After that I tried

sudo /etc/init.d/apache2 restart

After which ubuntu said: httpd (pid 5549) already running

Yet when I try to browse with chrome to the public ip which shows in the amazon console I get

This webpage is not available

ERR_CONNECTION_TIMED_OUT

In my browser. What am I doing wrong?

Answer 1

check your security group settings. What are the inbound rules? You need to add the IP(s) from where you are opening the web browser in the inbound rules. Also, check whether you are using private IP or public IP on the browser. You need to use public IP.
