error_log per Virtual Host?

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


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.

Apache Error Log Page


I usually just specify this in an .htaccess file or the vhost.conf on the domain I'm working on. Add this to one of these files:

php_admin_value error_log "/var/www/vhosts/example.com/error_log"

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.


Don't set error_log to where your syslog stuff goes, eg /var/log/apache2, because they errors will get intercepted by ErrorLog. Instead, create a subdir in your project folder for logs and do php_value error_log "/path/to/project/logs". This goes for both .htaccess files and vhosts. Also make sure you put php_flag log_errors on


Try adding the php_value error_log '/path/to/php_error_log to your VirtualHost configuration.
