This article is about how to output php error logs. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Output php error log: 1, modify the catch_workers_output and error_log configuration in php-fpm.conf; 2, modify php.ini configuration file; 3, restart php-fpm.

This article operating environment: windows10 system, php 7&&nginx 1.14, thinkpad T480 computer.

We all know that nginx is a web server, so the access log of nginx only records the visited page, not the 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 the errorlog of php can not be seen in the errors log of php-fpm.

The reason for this is that php-fpm 's configuration file php-fpm.conf turns off the error output of the worker process by default and redirects them directly to / dev/null, so we can't see the error log of php in nginx's errorlog or php-fpm 's errorlog.

But in this way, it will be very painful for us to debug, so how can we solve this problem? Let's take a look at it.

1. Modify the configuration in php-fpm.conf and add it if not.

Catch_workers_output = yeserror_log = log/error_log

2. Modify the configuration in php.ini. If not, add it.

Log_errors = Onerror_log = "/ usr/local/lnmp/php/var/log/error_log" error_reporting=E_ALL&~E_NOTICE

3. Restart php-fpm

When PHP executes errors, you can see that the error log is in "/ usr/local/lnmp/php/var/log/error_log".
