nginx php-fpm configuration method to output php error log

This article introduces how to configure php-fpm to output PHP error logs in the nginx server. Interested friends can refer to it. I hope it will be helpful to everyone.

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

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. In the errors of php-fpm You can’t see php’s errorlog in the log

Reason:
php-fpm’s 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 use nginx error Neither the log nor the errorlog of php-fpm can see the error log of php.

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

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

Copy the code Code example:

catch_workers_output = yes
error_log = log/error_log

2. Modify the configuration in php.ini, if not, add

Copy codeCode example:

log_errors = On
error_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 the error log in "/usr/local/lnmp/php/var/log/error_log"

Please note:
1. The php_admin_value[error_log] parameter in php-fpm.conf will override the error_log parameter in php.ini
So make sure the final error_log file you see in phpinfo() has writable permissions and does not Set the php_admin_value[error_log] parameter, otherwise the error log will be output to the error log of php-fpm.

2. The location of php.ini cannot be found, use php's phpinfo() to view the results
