web server on openstack instance

I installed a web server on a running openstack instance, then assign a port to it. When I try to access this web server using floating ip from both host and outside machines, I failed.

I'm wondering whether sth block access. I even add that port in security group and iptables, but failed as well.

Does anyone install web server on instance and start successfully? Even Apache failed to start using floating ip plus port.

As far as Apache goes, on the instance, what exactly do you mean when you say that it failed? What did the Apache error log say?

I presume that when you say that you're using the floating IP plus port on Apache, you mean in the Listen directive? It's generally a better idea to just use 'Listen 80' syntax (viz: http://httpd.apache.org/docs/2.4/mod/mpm_common.html#listen ) unless you actually want to distinguish between different IP addresses on that instance.

hi, thx for your comments. I changed to be Listen 80. Now when I typed "wget http://myinstancefloatingip" from openstack host, I can see the downloaded index.html. But I cannot see Apache page on browser, meaning if I type "http://myinstancefloatingip" on my browsers (e.g. IE, firefox), I didn't see anything. There's no errors in log as well.

do i need to modify iptables of both instance and openstack host? For instance, add NAT roles to translate fixed-ip to float-ip, or sth like it. Could you please tell me sth? I checked already, but still have no clue.

You need to open the ports on both: I would shutdown the firewall from the instance and also open all ports in openstack security. If it works after that, you can open only port 80/443.

Are you sure Apache is running ? You might want to check that as well.

There's some good info here: http://docs.openstack.org/trunk/opens...

You most likely can just add the pre-defined https or https security rules and be good to go. It works for me at least.
