Issues with reinstalling or upgrading PHP8? The lastest installer within DirectAdmin uses Phar
to install pear modules and what not. When you have used secure_php, this will result in issues like the one below:
PHP Fatal error: Uncaught Error: Call to undefined function popen() in phar:///usr/local/directadmin/custombuild/php-8.0.6/pear/install-pear-nozlib.phar/OS/Guess.php:254 .. .. Makefile:548: recipe for target 'install-pear-installer' failed make[1]: *** [install-pear-installer] Error 255 Makefile:551: recipe for target 'install-pear' failed make: *** [install-pear] Error 2
Or
The service 'php-fpm80' on server xxx is currently down This message has been automatically generated notifying you that the service php-fpm80 is currently down.
The latter normally could be resolved with a service restart, but not if the system tried to update your PHP installation. To resolve this, a few tiny steps will need to be performed resulting in a tiny bit of additional risk to your shared hosting machine.
Step 1: Allow popen as a PHP function
# Set Settings for Disabled PHP Functions (removing popen from the default list)
cd /usr/local/directadmin/custombuild
echo "exec,system,passthru,shell_exec,proc_close,proc_open,dl,show_source,posix_kill,posix_mkfifo,posix_getpwuid,posix_setpgid,posix_setsid,posix_setuid,posix_setgid,posix_seteuid,posix_setegid,posix_uname" > custom/php_disable_functions
# Rewrite the php.ini files
./build secure_phpStep 2: Reinstall PHP so it works
# Reinstall PHP (all versions as per options.conf)
cd /usr/local/directadmin/custombuild

(Optional) Step 4: Clean-Up
After the installation you could add popen
back to the list, but with the current way PEAR is installed, you will likely want to keep it as such for now, taking a slightly increased security risk. Better to have it so it auto-updates then having your system go down...
You could also simply delete the custom options by removing the file we created in step 1 located: /usr/local/directadmin/custombuild/custom/php_disable_functions
# Set Custom Settings for Disabled PHP Functions (adding popen again to the list)
cd /usr/local/directadmin/custombuild
echo "exec,system,passthru,shell_exec,proc_close,proc_open,dl,popen,show_source,posix_kill,posix_mkfifo,posix_getpwuid,posix_setpgid,posix_setsid,posix_setuid,posix_setgid,posix_seteuid,posix_setegid,posix_uname" > custom/php_disable_functions
