Connection refused after apache update

Question

After I updated my apache, none of my virtual hosts are accessible anymore, the server responds "Connection refused". No errors are in the logs and I have no idea what is causing this. My virtual host is something like this:

 <VirtualHost 173.XXX.XXX.XXX:80>
      ....
      ServerName hostname.com
      ....
 </VirtualHost>
 <VirtualHost 173.XXX.XXX.XXX:443>
      ....
      ServerName hostname.com
      ....
 </VirtualHost>

Any ideas of how to debug?

Of course! The apache is running. I also rebooted the system. — Lucas Pelegrino, Mar 15 '13 at 18:26

"Connection refused" would mean that apache is not listening on port 80; run this command to make sure" lsof -i:80, if you found no output then start apache and try again

Update: after seeing some output of different commands; it turned out that libapache2-mod-php5 is not installed according to dpkg -l | grep apache2 it was flagged as 'rc' (removed, but configuration files remaining). Since the debug information was showing loading mod_php5 then the absence of this package is what causing apache not to start

No output is given. Weird... I did `service apache2 start` and returned "Starting web server apache2 [OK]", after I tried `pgrep apache` and no output was shown. Is apache not being initialized, even saying [OK]?! – Lucas Pelegrino Mar 15 '13 at 18:32
try running 'apache2ctl -t' to test your configuration – minniux Mar 15 '13 at 18:35
Syntax OK. Everything was fine before the update. – Lucas Pelegrino Mar 15 '13 at 18:36
what about running: `apache2ctl -k start` ? – minniux Mar 15 '13 at 18:41
Tried and no output =/ – Lucas Pelegrino Mar 15 '13 at 18:42
let us try: `apache2ctl -k start -e debug` – minniux Mar 15 '13 at 18:44
Here is the output: http://pastebin.com/xeKiABy5. Something I noticed: /etc/hosts was completely different from what I had setup before the update, maybe some other configuration files were replaced? – Lucas Pelegrino Mar 15 '13 at 18:47
Hmmmm, if you're in doubt and if you got a backup of the old configs, you can run `apache2ctl -f /path/to/old_config`and also review the content on /etc/apache2/sites-enabled – minniux Mar 15 '13 at 18:51
I don't have a backup, I though would be a simple routine update =/ Everything OK under /etc/apache2/sides-enabled. Any way of debbuging more? Additional info: "netstat -nap | grep apache" returns nothing. – Lucas Pelegrino Mar 15 '13 at 18:57
I see you've got some errors in the upgrade with apache2/php packages.. run `dpkg -l | grep apache2`and let us know – minniux Mar 15 '13 at 19:07
Here it is: http://pastebin.com/QJfk9G0k – Lucas Pelegrino Mar 15 '13 at 19:08
Got that, libapache2-mod-php5 is removed. Please run `apt-get installlibapache2-mod-php5` and update the question with the relevant output – minniux Mar 15 '13 at 19:13

Do you have your "Listen" directives in your vhost files or in /etc/apache2/ports.conf?

You should have a line similar to :

Listen 80

I get this problem every time I get a major upgrade/update on Ubuntu. Solved it just by running the following command:

sudo a2enmod ssl
sudo a2enmod rewrite
sudo /etc/init.d/apache2 restart

Hope this helps!

apt-get upgrade problems

Another problem I found was that my lightdm stopped working. No GUI prompt after "apt-get upgrade". I found that lightdm was removed. I installed manually and all started working.
