Installing the SSH2 PHP extension on CentOS is actually pretty simple. Although it isn’t available as a straight yum install, it boils down to a few short steps.
These will allow us to build the SSH2 extension using pecl.
pecl install -f ssh2
After running that command, it should stop at a line like:
..
........done: 22,740 bytes
5 source files, building
running: phpize
Configuring for:
PHP Api Version: 20041225
Zend Module Api No: 20060613
Zend Extension Api No: 220060519
libssh2 prefix? [autodetect] :
All you have to do is hit Enter and it should detect the proper path.
Once the install is completed, you just have to tell PHP to load the
extension when it boots.
touch /etc/php.d/ssh2.ini
cat echo extension=ssh2.so > /etc/php.d/ssh2.ini
Now restart your webserver and test to see if the changes took effect.
