Install SSH module for PHP¶

This installation occurs on the web server.

The ssh2 extension for php¶

First, install the following prerequisites:

For newer systems the extension is available through the repository, e.g., on Fedora 12 type "sudo yum install php-pecl-ssh2"

CentOS 6: Install the ssh2 extension¶

sudo yum install php-pecl-ssh2

CentOS 5: Download and compile the ssh2 extension¶

This setup is almost identical to the Install the MRC PHP Extension. See http://www.php.net/manual/en/ssh2.installation.php for more information.

1. Go the website http://pecl.php.net/package/ssh2
2. Download the latest version of ssh2:

   wget http://pecl.php.net/get/ssh2-0.11.3.tgz

3. Extract the tar ball

   tar zxvf ssh2-0.11.3.tgz

4. Go into the directory

   cd ssh2-0.11.3

5. Run phpize and standard make process

   phpize
   ./configure
   make

6. Install the module:

   sudo make install

7. Add a ssh2.ini to your php ini folder:

   sudo touch /etc/php.d/ssh2.ini
   sudo chmod 666 /etc/php.d/ssh2.ini
   echo "; Enable ssh2 extension module" > /etc/php.d/ssh2.ini
   echo "extension=ssh2.so" >> /etc/php.d/ssh2.ini
   sudo chmod 444 /etc/php.d/ssh2.ini
   cat /etc/php.d/ssh2.ini
   

8. Restart httpd:

   sudo /sbin/service httpd restart

Test if the module is working:¶

1. go to the info.php that was created earlier in the Install the MRC PHP Extension, http://localhost/info.php or http://HOST.INSTITUTE.EDU/info.php
2. search for the ssh2 module, you should see this section:

Still having problems?¶

1. on one machine restarting httpd was not enough, I had to restart the entire system to get it working (even though it shows up under info.php)
