Set catch_workers_output for PHP-FPM to yes by default

Jordan

When trying to debug issues when using PHP-FPM it's important that catch_workers_output is set to yes as this will pass through any errors. Without this enabled, any page requests resulting in error code 500 will not be logged anywhere.

catch_workers_output bool
Redirect worker stdout and stderr into main error log. If not set, stdout and stderr will be redirected to /dev/null according to FastCGI specs. Default value: no.

Just a heads up, this is also an issue with LSPHP with OLS/LSWS. You need to add an ENV variable "LS_STDERR_LOG" to your LSPHP configuration block.

Unfortunately, Enhance doesn't start LSPHP isn't via OLS/LSWS; it's separate, so this configuration won't work. If you do have an application that is generating a 500 error with OLS or LSWS, you can find the error in journalctl or in syslog (/var/log/syslog) reported by appd.

I believe both PHP-FPM and LSPHP should have all their output logged to a log file. Otherwise people will bash their head against the wall for hours. Adam confirmed that it's possible to log this to a file somewhere.
