Where are the Apache and PHP log files?

  • 772

I've installed Apache, PHP, and MySQL on Ubuntu 10.10 desktop edition, and it's working fine.
Except I have no clue where to look for Apache or PHP log files.

log php apache2

  1. Best Answer

    By default, /var/log/apache2/error.log.

    This can be configured in /etc/php5/apache2/php.ini.

  2. Check these settings in php.ini:

    1. error_reporting = E_ALL | E_STRICT (as recommended for development in php.ini)
    2. error_log = /var/log/php_errors.log

    3. Then create log file manually 

      touch /var/log/php_errors.log
chown www-data: /var/log/php_errors.log
chmod +rw /var/log/php_errors.log

    Now you can view PHP errors by this way

    tail /var/log/php_errors.log

    This is an agreeable solution to this issue for me.

  3. You can also define a specific error log file for each VirtualHost in Apache. If you have any VirtualHost defined in /etc/apache2/sites-available/ and enabled in /etc/apache2/sites-enabled (enable with sudo a2ensite [your-virtualhost-definition-file]), you can change the error log by adding the following line inside your VirtualHost config:

    ErrorLog ${APACHE_LOG_DIR}/[your-vhost]-error.log

    That might be useful if you have a lot of vhosts and want to split where they report the errors.

    Also, you can watch your error log live by issuing the following command (adapt to your own log file if different from the default):

    sudo tail -f /var/log/apache2/error.log

    This is particularly useful when doing live debugging.

  4. If Apache was setup with Webmin/Virtualmin there is a separate folder for each VirtualHost.

    It is

    ~/logs

    folder for each VirtualHost user.

    These are two files:

    ~/logs/access_log

    and

    ~/logs/error_log

    So they are

    /home/onedomain/logs/access_log

    /home/onedomain/logs/error_log

    /home/anotherdomain/logs/access_log

    /home/anotherdomain/logs/error_log

    ...

    etc.

    To view log files for each particular domain login as VirtualHost owner user of that hostname and run

    tail -f ~/logs/error_log

  5. If you use a bitnami distribution, it is at:

    tail /opt/bitnami/apache2/logs/error_log

    Bitnami distributions have their own directory structure. I had to find what it was for my server, and this is where it resides by default for bitnami. I would assume lots of people are looking for the same thing when using a bitnami distribution.
