How can I set the location of the PHP error log in the apache conf file?
We have a finished PHP application running on a subdomain and it logs errors in it DocumentRoot:
/var/www/appname/path/to/document/root/php-errors.log
... instead of where we want the error logs:
/var/www/appname/logs/php-errors.log
Since I don't want to change the code in the finished application, and I don't want to change the location of the error log for all subdomains (read: php.ini), how can I only do this in the Apache conf file pertaining to the subdomain?

From: error_log for virtual host?
<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>

For those looking to do it with php-fpm (which I originally wrote about), here's how you do it:
Make sure you are logged in as root or use sudo
for all your commands.
Change to php-fpm * directory using below command:
cd /etc/php/fpm/
In this directory, edit the php.ini file and add the following at the end:
If you want to set error log by host
[HOST=www.example.com]
error_log=/var/www/myapplication/path/to/my/error.log
[HOST=sub.example.com]
error_log=/var/www/mysubapplication/path/to/my/error.log
If you want to set an error log along the way (handy if you are working on a server with an IP address but no domain)
[PATH=/var/www/myapplication]
error_log=/var/www/myapplication/path/to/my/error.log
[PATH=/var/www/mysubapplication]
error_log=/var/www/mysubapplication/path/to/my/error.log
Now you need to change to the pool directory * using the command below:
cd /etc/php/fpm/pool.d/
In this directory, edit the www.conf file. Note the values for user
and group
in this file, whose default settings are www-data
for both. Search for a term catch_workers_output
and make sure it's not catch_workers_output
and is set to a value yes
like so:
catch_workers_output = yes
Now you need to create an error log file and make sure php-fpm has access to it. This is why you needed to note the values for user
and group
from the previous file edit. Create an error log file for each HOST / PATH you set when editing php.ini
and give them the appropriate permissions and owner, for example:
touch /var/www/myapplication/path/to/my/error.log
chmod 0660 /var/www/myapplication/path/to/my/error.log
chown www-data:www-data /var/www/myapplication/path/to/my/error.log
Finally, restart the php-fpm service using the ** command below:
service php-fpm restart
* Note. If, like me, you install the declared versions of php-fpm, the directory paths change (for example) to the following:
/etc/php/5.6/fpm/
/etc/php/5.6/fpm/pool.d/
/etc/php/7.1/fpm/
/etc/php/7.1/fpm/pool.d/
** Service accepts a specific versioned name if you have installed the declared versions and you would need to use (for example) the following:
service php5.6-fpm restart
service php7.1-fpm restart

I set it up like this
/etc. / apache 2 / envvars
# for supporting multiple apache2 instances
if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
SUFFIX=
fi
export APACHE_LOG_DIR=/var/log/apache2$SUFFIX
/etc/apache2/sites-available/000-default.conf
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
