How to install PECL module ssh2 for PHP 7.2, 7.4

Introduction

The ssh2 PECL module install fails and is due to the current version being BETA. In order to work around this, a specific version needs to be installed for now.

The official PECL module website contains release information. Please see the following regarding ssh2: SSH2 PECL Module

Procedure

First, there are a couple of RPMs that should be installed. The following can be used to ensure they are installed.

yum -y install libssh2 libssh2-devel

Then the following can be executed to install the ssh2 PECL module for PHP 7.2

/opt/cpanel/ea-php72/root/usr/bin/pecl install ssh2-1.2

Then the following can be executed to install the ssh2 PECL module for PHP 7.4

/opt/cpanel/ea-php74/root/usr/bin/pecl install ssh2-1.2

and Apache restarted with

/scripts/restartsrv_httpd --hard

When trying to install the PECL module you may see an error similar to:

Warning: popen() has been disabled for security reasons in PEAR/Builder.php

and indicates that a PHP function is disabled. In order to temporarily work around this for pecl to install the PHP module, you can modify

for PHP 7.2

/opt/cpanel/ea-php72/root/usr/bin/pecl

for PHP 7.4

/opt/cpanel/ea-php74/root/usr/bin/pecl

and add the following line after the -d option settings

-d disable_functions=NULL \

Please note that this will not be an issue when the module developer pushes this to a stable version. Then the version will no longer be needed to install or update the ssh2 PECL module.
