I have upgraded to Centos 8, and find myself having to cope with the changes in Apache 2.4. I’ve started to get it working, but I have a perplexing error with a simple setting in .htaccess:
# .htaccess
# PHP Time Zone
php_value date.timezone Australia/Melbourne
I get the dreaded error:
The server encountered an internal error or misconfiguration and was unable to complete your request.
There’s no point contacting the server administrator because that’s me.
The error_log file has this:
Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration
This has always worked in the past on Apache 2.4, and also works when I use Apache 2.4 on XAMPP. So obviously there is something in some other configuration, possibly in httpd.conf which causes it to crash.
What setting am I missing, or should I change?
Update
As answered by @Chi.C.J.RajeevaLochana below, the solution lies in using the correct MPM. In my case, in the file 00-mpm-conf:
Comment out
LoadModule mpm_event_module modules/mod_mpm_event.so
Uncomment
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
For further information, see:
When you are using either mod_mpm_event or mod_mpm_worker instead of mod_mpm_prefork, you will not be able to use the PHP Module. This is because mod_mpm_event and mod_mpm_worker are threaded modules. And the PHP module is not thread safe.
If you are unsure how to do this, check out Soufiane ELH's tutorial which should be above/below this answer.
the event module is enabled by default on centos 8 .. to check wich module you have :
#sudo httpd -V | grep -i mpm
if you have enent module enabled, disable it, and enable the prefork module:
check again the module enabled by apache and you will find prefork :
# sudo httpd -V | grep -i mpm
Server MPM: prefork
