ubuntu apache store logs in home folder

Question

Im trying to setup a server with apache where each user has a logs folder in his home folder and all error/access logs are store in that folder.

My current setup:

<VirtualHost *:80>
  DocumentRoot /home/user/public_html

  ErrorLog /home/user/logs/error.log
  CustomLog /home/user/logs/access.log combined
  LogLevel info

</VirtualHost> 


<VirtualHost *:80>
 DocumentRoot /home/user1/public_html

 ErrorLog /home/user1/logs/error.log
 CustomLog /home/user1/logs/access.log combined
 LogLevel info

</VirtualHost> 

The problem with this setup is that if i access the site of user1

  http://localhost/~user1/

all logs are stored into /home/user/logs/ instead of /home/user1/logs/. How can i fix this so that the logs will be stored in the right place?

Answer 1

CustomLog for apache 2.2 is a per server or per virtual-host setting and the http://localhost/~user1/ and http://localhost/~user2/ type URI scheme are all aliases within the same default virtual-host.

Something like the following works for the CustomLog (ErrorLog doesn't seem to support the env modifier)

<VirtualHost *:80>
  DocumentRoot /var/www/html
  ErrorLog logs/error_log

  SetEnvIf Request_URI ^~user1 user1
  SetEnvIf Request_URI ^~user2 user2

  CustomLog /home/user1/logs/access.log combined env=user1
  CustomLog /home/user2/logs/access.log combined env=user2

 ...
</VirtualHost>

You need to consider that, with a non-trivial amount of users, giving each his own logs will place extra resource requirements on apache.

There is a simple limit on the number of log files it can handle - the system's file descriptor limit.

Additionally, you cannot split the error log within a single vhost.
