Problems with apache2 and virtualHosts - apache2

Question

I am trying to set up a virtual host at localhost. I am installing symfony 1.4 on my ubuntu 12.04 LTS, but I got some problems.
I installed apache2, php5 and mySql. Localhost works so I assume that apache it's ok.
You can found symfony installation and configuration instructions here.
After several days these are my configuration files:
http.conf:
ServerName 127.0.0.1
/etc/apache2/sites-available/test:
# Be sure to only have this line once in your configuration
NameVirtualHost 127.0.0.1:8080
# This is the configuration for your project
Listen 127.0.0.1:8080
<VirtualHost 127.0.0.1:8080>
DocumentRoot "/home/user/test/web"
DirectoryIndex index.php
<Directory "/home/user/test/web">
AllowOverride All
Allow from All
</Directory>
Alias /sf /home/user/test/lib/vendor/symfony/data/web/sf
<Directory "/home/user/test/lib/vendor/symfony/data/web/sf">
AllowOverride All
Allow from All
</Directory>
</VirtualHost>
and localhost:8080 doesn't works.
UPDATE:
Ok, after several modifications my httpd.conf is the same:
ServerName 127.0.0.1
And my /etc/apache2/sites-available/test:
Listen 127.0.0.1:80
<VirtualHost 127.0.0.1:80>
DocumentRoot "/home/user/test/web"
DirectoryIndex index.php
<Directory "/home/user/test/web">
AllowOverride All
Allow from All
</Directory>
Alias /sf /home/user/test/lib/vendor/symfony/data/web/sf
<Directory "/home/user/test/lib/vendor/symfony/data/web/sf">
AllowOverride All
Allow from All
</Directory>
</VirtualHost>

Answer 1

If Apache use the port 80, remove this line in your conf:
NameVirtualHost 127.0.0.1:8080
Then replace all 8080 by 80 and try http://localhost. It should work.
edit:
Regarding the error could not bind to address 127.0.0.1:80 no listening sockets available, it seems you have an other server listening on the port 80.
Maybe it's a better idea to come back on the 8080 port (on the httpd.conf) and then update the ports.conf to set :
NameVirtualHost *:8080
Listen 8080
If you don't have a ports.conf file, find Listen in your main configuration file and do the update.

Answer 2

Verify you have your site test into /etc/apache2/sites-enabled/. if not do:
sudo a2ensite test
This command will enable the site test. Remember to restart apache.

Answer 3

Error message.
(98)Address already in use: make_sock: could not bind to address 127.0.0.1:80 no listening sockets available, shutting down Unable to open logs
It can be solved by commenting out the line Listen 80 in your httpd.conf file.
