每个虚拟主机error_log?

On one Linux Server running Apache and PHP 5, we got multiple Virtual Hosts with separate logfiles and everything. The only thing we cannot seem to separate between virtual hosts is the php error_log.

Overriding this setting in the <Location> of the httpd.conf does not seem to do anything.

Did I overlook something? Is there a way to have separate php error_logs for each Virtual Host?

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.

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

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 is for error_log() 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

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

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

<VirtualHost myvhost:80>
ServerAdmin [email protected]
DocumentRoot /opt/web
ServerName myvhost
ErrorLog logs/myvhost-error_log
CustomLog logs/myvhost-access_log common
</VirtualHost>

yes, you can try php_value error_log "/var/log/php_log" in .htaccess or you can have users use ini_set() in the beginning of their scripts if they want to have logging

Another option, would be to enable scripts to default to the php.ini in the folder with the script, then go to the user/host's root folder, then to the server's root, or something similar. This would allow hosts to add their own php.ini values and their own error_log locations.

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

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

Or Apache will write the log to the its error_log.

You could try:

    <VirtualHost myvhost:80>
       php_value error_log "/var/log/httpd/vhost_php_error_log"
    </Virtual Host>

But i'm not sure if is going to work. I tried on my sites with no success.
