Instructions for installing Phalcon on Directadmin

By default custombuid directadmin supports installing Phalcon but only supports phalcon version 4. So BKNS guide you to install Phalcon on Directadmin according to custombuild and compile from source for low version.

Currently Phalcon version is 4.0.4, this extension only support on PHP 7+, low PHP version is not supported

1: Instructions to install Phalcon from custombuild directadmin

By default custombuid directadmin supports installing Phalcon but only supports phalcon version 4

cd /usr/local/directadmin/custombuild/

./build php_phalcon

2: Instructions to compile from source (install phalcon version 3.x)

In the case of switching from Phalcon 3 to a server running Phalcon 4, you may get an error:

Uncaught BadMethodCallException: Wrong number of parameters in public_html/public/index.php:31 Stack trace:

There are 2 ways to fix updating the code according to the new version, this method takes time, so BKNS instructs us to install Phalcon version 3 to fix it.

Please follow the instructions below

Get phpize path

[root@vps build]# whereis phpize

phpize: /usr/local/bin/phpize

php-config executable Path

[root@vps build]# whereis php-config

php-config: /usr/local/bin/php-config

Download Phalcon

yum install pcre-devel gcc make git

git clone https://github.com/phalcon/cphalcon

cd cphalcon/build

git checkout origin/3.4.x

./install --phpize /usr/local/bin/phpize --php-config /usr/local/bin/php-config --arch 64bits

In the above settings, you change the parameters phpize, php-config according to the parameters above, arch version OS,

After the installation is complete, a message like the following image will appear.

Add extension to php.ini

You run the following command to get the location of the php config file (this path is for the default php on the server in case you use multiple versions of php, you need to choose the correct file location)

[root@vps build]# php --ini

Configuration File (php.ini) Path: /usr/local/php73/lib

Loaded Configuration File:         /usr/local/php73/lib/php.ini

Scan for additional .ini files in: /usr/local/php73/lib/php.conf.d

Additional .ini files parsed:      /usr/local/php73/lib/php.conf.d/10-custom.ini,

BKNS creates an additional file /usr/local/php73/lib/php.conf.d/10-custom.ini to avoid being overwritten.

echo "extension=phalcon.so" > /usr/local/php73/lib/php.conf.d/10-custom.ini

Once done, restart the webserver.
