Foreword:

We know that nginx is a web server, so the access log of nginx only records the accessed pages, and there will be no error log information of php.

nginx sends the request for php to the php-fpm fastcgi process for processing. The default php-fpm will only output the error message of php-fpm, and php cannot be seen in the errors log of php-fpm. errorlog. The reason is that the php-fpm configuration file php-fpm.conf defaults to turning off the error output of the worker process and redirecting them directly to /dev/null, so we can neither see the error log of nginx nor the error log of php-fpm. to the php error log.

How to solve the problem that php-fpm under nginx does not record php error logs:

Modify the configuration in php-fpm.conf and add it if there is no configuration.

catch_workers_output = yes
error_log = log/error_log

Modify php. ini configuration, if not, add

log_errors = On
error_log = "/usr/local/lnmp/php/var/log/error_log"
error_reporting=E_ALL&~E_NOTICE

Restart php-fpm
