Setting "error_log" location is not taken into account


A similar question has been asked already at PHP's configuration setting 'error_log' is not working, but that's not my problem.

My phpinfo(); shows

Directive Local Value Master Value
error_log /var/opt/remi/php74/log/php-fpm/www-error.log /var/opt/remi/php74/log/php-fpm/www-error.log
max_execution_time 456 456

I try to change location to /var/log/php-fpm/www-error.log, however the location always stays on /var/opt/remi/php74/log/php-fpm/www-error.log not matter what I am doing

File /etc/php.d/impng.ini

max_execution_time = 456
error_log = /var/log/php-fpm/www-error.log

I run systemctl restart httpd / systemctl restart php74-php-fpm several times

I don't see file /var/opt/remi/php74/log/php-fpm/www-error.log configured anywhere:

$ grep php_admin_value /etc/httpd/conf/*
$ grep php_admin_value /etc/httpd/conf.d/*
$ grep php_admin_value /etc/httpd/conf.modules.d/*
$ grep php_admin_value /etc/php.d/*
$ grep error_log /etc/php.d/*
/etc/php.d/impng.ini:error_log = /var/log/php-fpm/www-error.log
    
$ grep ErrorLog  /etc/httpd/conf/*
/etc/httpd/conf/httpd.conf:# ErrorLog: The location of the error log file. 
/etc/httpd/conf/httpd.conf:# If you do not specify an ErrorLog directive within a <VirtualHost> 
/etc/httpd/conf/httpd.conf:ErrorLog "logs/error_log"

$ grep ErrorLog  /etc/httpd/conf.d/*
/etc/httpd/conf.d/ssl.conf:ErrorLog logs/ssl_error_log

$ grep ErrorLog  /etc/httpd/conf.modules.d/*

Note, errors are written properly to /var/opt/remi/php74/log/php-fpm/www-error.log. Manual logging with error_log("test", 3, "/var/log/php-fpm/www-error.log"); is also working.

But I don't manage to change the location of error_log. Other parameters (e.g., max_execution_time) are taken properly into account as expected.

It's a minor issue. I could create symbolic link or simply read file /var/opt/remi/php74/log/php-fpm/www-error.log. However, I wonder why I cannot change it.


Solution

  • In Fedora and RHEL / CentOS 8, PHP is executed via the php-fpm service.

    And the log is configured in the pool configuration file.

    File /etc/opt/remi/php74/php-fpm.d/www.conf

    ...
    ; Default Value: nothing is defined by default except the values in php.ini and
    ;                specified at startup with the -d argument
    ;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f [email protected]
    ;php_flag[display_errors] = off
    php_admin_value[error_log] = /var/opt/remi/php74/log/php-fpm/www-error.log
    php_admin_flag[log_errors] = on
    ;php_admin_value[memory_limit] = 128M
    
    ; Set the following data paths to directories owned by the FPM process user.
    ;
    ; Do not change the ownership of existing system directories, if the process
    ; user does not have write permission, create dedicated directories for this
    ; purpose.
    ;
    ; See warning about choosing the location of these directories on your system
    ; at http://php.net/session.save-path
    php_value[session.save_handler] = files
    php_value[session.save_path]    = /var/opt/remi/php74/lib/php/session
    php_value[soap.wsdl_cache_dir]  = /var/opt/remi/php74/lib/php/wsdlcache
    ;php_value[opcache.file_cache]  = /var/opt/remi/php74/lib/php/opcache
    ;php_value[opcache.preload] = /var/www/html/preload/preload.php
    ;php_value[opcache.preload_user] = apache
    

    It has to be configured in the spool file, as each pool may run under a different user, so each needs its own files.

    Tips: you can see the configuration files provided by a package using:

    rpm --query --configfiles php74-php-fpm
    

    /etc/httpd/conf.d/php74-php.conf
    /etc/logrotate.d/php74-php-fpm
    /etc/opt/remi/php74/php-fpm.conf
    /etc/opt/remi/php74/php-fpm.d/www.conf
