I am curious about Amazon webservices and so I thought of creating a dynamic webpage with Amazon EC2. I created an instance, installed apache and php and made sure it is working in EC2(using remote access). I have assigned a elastic IP to the instance. My question is how to access the webpage that I created in the instance. I am not sure what to give the servername in httpd.conf. My goal is access the page like http://amazonaddress/test.php
I am using windows server, but I think it is basically the same. My documents are in the same folder as mentioned in conf file. But when I use my elastic IP, it isn't working . Not even the basic index page in the apache htdocs(that's the home folder according to conf). To throw more light I will explain what I have done till now.
I have created a micro instance(EC2) and logged into it using remote desktop. I have installed apache msi file and php after that. I have created a elasticIP and attached the instance and to my security group I have added http service to port 80. I have tested if localhost is working in my remote machine(points to index.html). After that I have tried accessing it using elastic IP and it just times out. Is there any step I have missed?
You can access it via http://255.255.255.255 where you replace the 255.255.255.255 with your elastic IP address.
Then you want to setup DNS for your domain name. So you'll need to create an A Record mapping www.yourdomain.com to whatever your elastic IP address is. You can usually do this via your domain name registrar as most of them also run basic DNS services for free.
You can access an ec2 instance using it's public DNS name (or elastic IP since you already have one of those), which can be seen in the instances description tab. Configuring your personal domain name to point to that server will involve creating an A Record mapping to that public IP.
Assuming apache has been setup correctly, that's all you should need to do to get started (and your test.php page is in /var/www/). For your purposes, you probably shouldn't even need to modify the httpd.conf file at all.
Also, be sure to remember to open a port on the security group (under Network & Security from the EC2 Console) that the instance belongs to. In your example, you will want to open port 80 inbound with source 0.0.0.0/0 (unless you want to limit access to a specific IP range).
Hope this helps.

I have a test application running at
http://ec2-34-215-196-193.us-west-2.compute.amazonaws.com/
(This is a Test application, it wont be live for long. When I try to add a CNAME to this, like the screenshot below
. is added by the DNS system.
However, my app seems to be accessible only via us-west-2.compute.amazonaws.com or us-west-2.compute.amazonaws.com.
I can make it to resolve it either one of them.
But adding anything, does not seem to resolve with a CNAME. It gives 503 Service Unavailable.
I am using AWS EC2 to host the app with a HAProxy Load Balancer.
Using Google Domains for DNS Name.
Any suggestions for troubleshooting this problem?
All dns entries have a dot in the end like subdomain.domain.com.
It's not suggested to create CNAMEs to your ec2 instance because that IP may vary in time and it's not reassignable, that's what elastic ip's are made for, just create an elastic IP, assign it to your ec2 instance and assign it as an A record on your DNS provider.
Amazon AWS documentation
First create elastic IP and assign to your instance. Then create A record and point IP. Your site should work normal.
i have created new instance in amazon ec2, and assigned the elastic ip for instance. But i need to know how to get ip for name server (ns1.abc.com, ns2,abc.com).
I have installed whm in amazon instance. Only domain cannot point to the correct name server. That is because ip cannot load.
Now, my problem is that how i get new ip. Can i add another two elastic ip in amazon? But i configured two elastic ip for name server in dns zone within whm. The name server is not working. And i cannot open the elastic ip in browser. I am confuse for it. Please anyone help me.
There are lots of things that can go wrong here. I'll try to troubleshoot step by-step:
I'll assume the goal is "You want to type 'whm.foo.com' and see your WHM"
1) Go to your domain registrar and make an entry that points "whm.foo.com" to your EIP. (Depending on what you want, maybe you should setup a "*.foo.com" wildcard for that EIP.
2) Test that step #1 worked by typing "ping whm.foo.com" or "dig whm.foo.com" (one linux/mac, not sure about Windows). This should return your EIP. If not, go back to step 1.
3) Check that WMH is acually running. Read the docs to find what port it's running on. (Usually 2083, or 2082 for insecure access)
On your instance, run "curl -v localhost:2083" (or whatever port. It should return a login screen. If it says "couldn't connect to host", then you have the wrong port or it's not running.
4) run "netstat -na | grep :2083" (or whatever port). It should say "0.0.0.0:*". If it says "127.0.0.1:*", then you need to configure it to allow outside access.
5) Make sure your WHM port is enabled in the AWS firewall. Go to the AWS control panel and find the security group for your box. Make sure that port is allowed. Ideally, you'd only add your personal IP instead of opening it up to the world. (If there is a bug in WHM, people will scan all IPs trying to exploit it. They can't exploit your server if the AWS firewall denies them access.)
6) Now type "https://whm.foo.com:2083" (or whatever port) in your browser. (or http://whm.foo.com:2082 for insecure access). It should work!
i need to know how to get ip for name server (ns1.abc.com, ns2,abc.com).
As rdrey said, you need to go to your DNS provider (most registrars also do DNS) and tell them what boxes should point to your EIP.
That is because ip cannot load.
There is no such thing as "ip cannot load". Either "DNS is giving the wrong IP" or "some IP operations (TCP ports) were blocked by a firewall somewhere".
Now, my problem is that how i get new ip
I don't think that should be your goal. You can easily change EIPs, but it won't fix the problem. Nothing works unless everything in between is set up correctly. The goal should be understanding all the steps in the process and verifying that each step was done correctly.
OK, you have two options here:
Use the DNS servers provided by your Domain Registrar OR
Use AWS Route53 to let Amazon provide DNS services for you.
Option 1:
You bought your domain name from a registrar, like one of these: http://lifehacker.com/5683682/five-best-domain-name-registrars
Most, if not all, registrars run a free DNS service for their customers. You should be able to log into some kind of management console and set your domain's DNS zone entries to point at your AWS EIP. (I am using gandi.net and used to use godaddy. You simply leave the DNS Servers as they are and set your AWS EIP as the 'A' record.)
Option 2:
Go to https://console.aws.amazon.com/route53/home and follow instructions. I haven't read up on Route53's pricing, so this option might not be free.
---- EDIT:
Some more help:
The site you've linked to (http://www.intodns.com/xantec.com.sg) states that you've used your EIP (54.251.169.7) as the nameserver for the domain. You don't want that. You're running a cPanel installation, NOT a DNS nameserver.
Put 54.251.169.7 as your site's A record. (Sometimes called the www field.) Remove it from the NS fields and put ns3.thesimpledns.com & ns4.thesimpledns.com into those.
I have a domain www.rentcars.sg which is pointed to the right DNS server and verified by someone else and is working correctly: https://forums.aws.amazon.com/message.jspa?messageID=362885#362885
However, even though I setuped the domain correctly on the server with IIS, it's not working correctly.
Can anyone point me to the right direction? Is there any additional setup I need to make to get it working?
Server IP : 23.23.129.247
Using the internal IP, it works but not with the server ip with port/url.
I am not sure if I understand your problem, but my approach would be:
Allocating EC2 Elastic IP Address.
Associating such an address with your running EC2 instance.
Pointing your domain name to this IP address.
Adding inbound TCP rule for all IP sources (0.0.0.0/0) in Security Group settings belonging to your EC2 instance.
Keep in mind that windows instances in AWS come with the software (windows) firewall enabled by default. Make sure that you have the correct firewall policies in place in the software firewall as well as the security group.
I am facing a few issues.
I initially had assigned an elastic IP to my micro instance i-38cbc940, but for some reason, after I did that the webpages I had uploaded were not functioning properly (images not loading correctly, etc).
I tested this prior to the elastic IP assignment and such problems were not occurring. So I dissociated the elastic IP address and released it. Then, I reboot my instance.
The problem is, now I cannot view my site in a browser using the public DNS address listed (ec2-23-23-18-52.compute-1.amazonaws.com) or any of its sub-directories.
Things I Know:
My security settings have not changed - I still have the same security group identified with the instance.
httpd.conf file still shows "/var/www/html" as the DocumentRoot.
Every time I navigate to the public DNS address listed...it shows "could not connect" but if I ping it, it works.
If I SSH into the instance in the var/www/html directory, everything is still there, including an index.html file that was viewable before. Also, I can get into the instance through PuTTY.
Also, no sure if it's important, but this is an AmazonEC2-AMI/Apache/MySQL server with Wordpress CMS installed.
Any ideas on what could be going on here?
you need to check the apache conf for any hardocoded dns entries of your instance amazon dns and also check your code for any referrals to the amazon dns of your instance.
I have a free Amazon EC2 instance. And I installed Apache web server on it. I have the DNS record for my domain point to the ip for the EC2 instance. I can not access to my website. Then I looked up and allow the http inbound. But I still failed to access my web? What might be the reason. Anybody gives me a clue?
Go to the AWS management console and look at the Security Group the instance is in. Then make sure you have the port open that you are trying to connect to (most likely 80). To open it to the world set the ip range to 0.0.0.0/0 and to open it to a specific ip (like only your house) set it to xxx.xxx.xxx.xxx/32.
That is almost always the reason people have problems connecting when they are new to AWS. I wrote this post, which should help get you setup.
