Can't access Apache in my CentOS Virtualbox

Question

I'm setting up a VirtualBox with CentOS so I can test out all my code, etc. on a Linux box instead of the Windows I use for development.

I just got the SSH working (I SSH to localhost:2222 and it port forwards it to the virtualbox port 22).

It's using NAT because for some reason it refuses to start with a bridged adapter.

I'm trying to do the same thing with Apache, to get a web server up and running.

I've portforwarded port 8888 on localhost to port 80 in my CentOS Virtualbox, but I can't seem to access anything with localhost:8888 in my browser?

Apache is also definitely running:

ps -e | grep httpd
2108  ?      00:00:00 httpd
2110  ?      00:00:00 httpd
2111  ?      00:00:00 httpd
2112  ?      00:00:00 httpd
2113  ?      00:00:00 httpd
2114  ?      00:00:00 httpd
2115  ?      00:00:00 httpd
2116  ?      00:00:00 httpd
2117  ?      00:00:00 httpd

I've also stopped iptables, so that's not interfering. I tried to telnet into port 80 from my CentOS Virtualmachine to see if it'd work, and Neither 127.0.0.1 or [vm ip] works for telneting to port 80. It gets to connecting to [ip] and then says connection closed by foreign host. For the listen lines in my httpd.conf, it says listen 0.0.0.0:80

Output of netstat -tlnp | grep http

netstat -tlnp | grep http
tcp        0      0 0.0.0.0:80                       0.0.0.0:*                        LISTEN      2032/httpd

When I nmap localhost, I get

[root@CentOS conf]# nmap localhost

Starting Nmap 5.21 ( http://nmap.org ) at 2012-01-28 00:58 WST

Solution

You have copy pasted the iptables rules? If yes then there is an error in it:

 _I OUTPUT -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT

the underscore insted of hyphen.

Looks like you are binding to ipv6 only and not ipv4 - you may need to explicitly specify the use of ipv4 with Listen 0.0.0.0:80 (Apache docs). (Also check that localhost maps to 127.0.0.1 and not just to ::1 in /etc/hosts - but that is unlikely).

@ShaneMadden definitely sure it's the right IP

[user1045696]

Hosts: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.2.15 localhost

@ShaneMadden So I somehow fixed the IP issue, nmaping the IP address is now the same as nmaping localhost. However, it's still not working. I also can't ssh into the IP address directly (10.0.2.15:22) so I assume it's the same issue that's messing things up

[user1045696]

Wgeting also works perfectly, whether it's localhost/index.html, 127.0.0.1/index.html or 10.0.2.15/index.html. I'd assume it's a port forwarding issue if the SSH didn't work perfectly

[user1045696]

@cyberx86 Done. Everything works from the local machine now, just not my windows host?

[user1045696]

I've edited the OP with the output, I'm not entirely sure what it means?

[user1045696]

Should have said, I've fixed that, editing the post now :)
