I am having trouble connecting to an Amazon Elastic Cloud Computer Instance via a browser. I attempted going to ********.compute-1.amazonaws.c
Do not forget to disable firewall if you use windows for your server.
The EC2 instance firewall is maybe enabled. Check it with this command:
sudo systemctl status firewalld
if enabled you can disable it with :
sudo systemctl disable firewalld
or setup rules to allow port 80 trafic
I faced the same issue while setting up redash AMI image on AWS. Inbound security rules should be changed when instance is not running. Let's say if the instance is running (meaning it's active and started); If you change the inbound rules of that machine you'll still face firewall issue. So Stop the machine on which you want to change the inbound rules on. Change the inbound rules. Start the machine now. Now you can hit the machine url from the ip you just opened the access to the machine to.
I had also faced similar issue with ec2 micro instance. I was using Red-Hat AMI. Despite of opening ports 8081 in security group, I was not able to a telnet to the host port. Disabling the iptable did the trick for me:
sudo /etc/init.d/iptables stop
By default, your instances will only be in the default
security group. If it's an EC2 instance you cannot change security groups while the instance is running, you'll have to specify them in advance. If it's a VPC instance you can change security groups at runtime.
default
groupYou can however add the rule to allow port 80 to that default
security group; just don't create a new security group as it can not be associated with the running instance.
Also, make sure that your web server is up and running. From your instance (using SSH shell access), check if the right process is listening on port 80, using the command netstat -lnp
. You should then see a row with proto
tcp
and a Local Address
ending in :80. The IP Address listed should be either 0.0.0.0 (meaning 'any IP') or a specific IP of a listening network interface.
If you are in need of a web server, take a look at Apache or Nginx. They both support PHP.
Hope this helps.
