error_log per Virtual Host?

Question

On one Linux Server running Apache and PHP 5, we have multiple Virtual Hosts with separate log files. We cannot seem to separate the php error_log between virtu

Answer 1

If somebody comes looking it should look like this:

<VirtualHost *:80>
    ServerName example.com
    DocumentRoot /var/www/domains/example.com/html
    ErrorLog /var/www/domains/example.com/apache.error.log
    CustomLog /var/www/domains/example.com/apache.access.log common
    php_flag log_errors on
    php_flag display_errors on
    php_value error_reporting 2147483647
    php_value error_log /var/www/domains/example.com/php.error.log
</VirtualHost>

This is for development only since display_error is turned on. You will notice that the Apache error log is separate from the PHP error log. The good stuff is in php.error.log.

Take a look here for the error_reporting key http://www.php.net/manual/en/errorfunc.configuration.php#ini.error-reporting

Answer 2

The default behaviour for error_log() is to output to the Apache error log. If this isn't happening check your php.ini settings for the error_log directive. Leave it unset to use the Apache log file for the current vhost.

Answer 3

php_value error_log "/var/log/httpd/vhost_php_error_log"

It works for me, but I have to change the permission of the log file.

or Apache will write the log to the its error_log.

Answer 4

Have you tried adding the php_value error_log '/path/to/php_error_log to your VirtualHost configuration?

Answer 5

My Apache had something like this in httpd.conf. Just change the ErrorLog and CustomLog settings

<VirtualHost myvhost:80>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot /opt/web
    ServerName myvhost
    ErrorLog logs/myvhost-error_log
    CustomLog logs/myvhost-access_log common
</VirtualHost>

Answer 6

To set the Apache (not the PHP) log, the easiest way to do this would be to do:

<VirtualHost IP:Port>
   # Stuff,
   # More Stuff,
   ErrorLog /path/where/you/want/the/error.log
</VirtualHost>

If there is no leading "/" it is assumed to be relative.
