Symptoms
- Server runs out of the space because of PHP-FPM logs
- Currently,
/var/log/plesk-php-7x-fpm/error_log
is shared and all domains write errors to it. As a result it is not included into any domain disk space statistics - As well as currently Plesk configured to rotate this log file on daily basis.
Cause
The issue is considered to be a bug with ID PPPM-11362.
Resolution
As a workaround, an additional log rotation by size for a PHP-FPM error log can be configured using native OS utilities, for example, the logrotate. For more details refer to the logrotate documentation: https://linux.die.net/man/8/logrotate
The logrotate configuration file for PHP-FPM services is located in /etc/logrotate.d/
directory:
# ls -l /etc/logrotate.d/php
-rw-r--r-- 1 root root 203 Nov 15 23:36 /etc/logrotate.d/php-fpm
-rw-r--r-- 1 root root 211 Jan 9 13:25 /etc/logrotate.d/plesk-php56
-rw-r--r-- 1 root root 211 Jan 9 12:46 /etc/logrotate.d/plesk-php70
-rw-r--r-- 1 root root 211 Jan 9 11:11 /etc/logrotate.d/plesk-php71
-rw-r--r-- 1 root root 211 Jan 9 14:50 /etc/logrotate.d/plesk-php72
-
Connect to the server via SSH.
-
Modify the corresponding file for required php-fpm service in an appropriate way:
For example, for system PHP-FPM/etc/logrotate.d/php-fpm
file will look like the following:CONFIG_TEXT: /var/log/php-fpm/*log {
rotate 14
daily
missingok
notifempty
size 100M
compress
missingok
notifempty
sharedscripts
delaycompress
postrotate
/bin/kill -SIGUSR1cat /run/php-fpm/php-fpm.pid 2>/dev/null
2>/dev/null || true
endscript
}Note: parameters rotate (specified in days), size and daily (or monthly, weekly) can be changed to meet the requirements.
If it is required to rotate log files more often, then remove parameter daily from the config above and create a cron task. For example, the following will run logrotate every 5 hours:
# crontab -e
01 01,06,11,16,21 * * * /usr/sbin/logrotate /etc/logrotate.d/php-fpm -s /var/lib/logrotate/logrotate.status
