Not loading ‘libphp5’ module with CA on apache2.4.51

On Macbook M1Max.
Installed PHP5.6 by ‘shivammathur/php/php@5.6’ via Homebrew.
And set the module info on a configuration file(httpd.conf) of Apache.

LoadModule php5_module /opt/homebrew/opt/php@5.6/lib/httpd/modules/libphp5.so "apache2"

then passed apachectl syntax check that has no error.

$ apachectl configtest
[Fri Jan 14 19:48:05.352957 2022] [so:notice] [pid 5436] AH06662: Allowing module loading process to continue for module at /opt/homebrew/opt/php@5.6/lib/httpd/modules/libphp5.so because module signature matches authority "apache2" specified in LoadModule directive
Syntax OK

BUT, apache still occurred below errors.

httpd: Syntax error on line 190 of /private/etc/apache2/httpd.conf: Code signing error - not loading module at: /opt/homebrew/opt/php@5.6/lib/httpd/modules/libphp5.so

How can fix them?

Answer

Please use httpd package from Homebrew instead of system Apache as that requires code signing.

• Unload the system Apache

sudo apachectl stop
sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

• Make sure httpd is installed using brew

brew install httpd

• Then you can configure httpd to run PHP using /opt/homebrew/etc/httpd/httpd.conf config file.

• Once done, restart httpd and it should work.

brew services restart httpd
