Configuring Apache on CentOS 5.7

I've purcheased a vps and installed apache2. As developer i've been doing this hundreds of times with no problem. Now I'm facing this: netstat -nao outputs apache2 is listening on :::80 but not on 0.0.0.0:80

I get NO errors at all. Logs have no errors too.

Ideas? Links? Blog posts? Thanks!

  • What exactly is the problem your facing. – user9517 Jun 01 '12 at 08:43
  • I would expect from netstat 0.0.0.0:80 listening socket... but I only get :::80. So when trying to browse mywebsite.com... it obviously refuses connection – user1170896 Jun 01 '12 at 08:45
  • Did you open port 80 in your firewall ? – user9517 Jun 01 '12 at 08:47
  • Yes. but didn't work. Anyway I think I should see 0.0.0.0:80 listening even if a firewall is blocking it... Am i wrong? – user1170896 Jun 01 '12 at 08:48
  • My centos system says the same and works as expected, your problem isn't one of binding. – user9517 Jun 01 '12 at 08:55
  • uhmmm ok. 1 problem less – user1170896 Jun 01 '12 at 08:56
  • So why ssh service is showing :::22 and 0.0.0.0:22 ? – user1170896 Jun 01 '12 at 09:10
  • What do you mean by, "installed apache2"? CentOS ships with Apache 2, but it's named "httpd" as the package. Did you install apache2 separately? Is it conflicting with the pre-installed httpd package? – cjc Jun 01 '12 at 10:23
  • Ok the problem was iptables. I did insert a rule to allow incoming requests on port 80 but "-A" is for Append... and the rule never had the chance to be matched. So using "-I" for insert solved the problem. iptables -I INPUT -i eth0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT – user1170896 Jun 01 '12 at 12:08

Binding to :::80 means that it is listening to both IPv4 and IPv6 connections; this is not causing your problem.
