Install SSH module for PHP¶

This installation occurs on the web server.

The ssh2 extension for php¶

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

Download and compile the ssh2 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/ssh2-0.11.0.tgz

3. Extract the tar ball

   tar zxvf ssh2-0.11.0.tgz

4. Go into the directory

   cd ssh2-0.11.0

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 mrc extension module" > /etc/php.d/ssh2.ini
   echo "extension=mrc.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

The extension module is added to php in the same way as does the php-mrc module we distribute for the viewing mrc images through php. To check whether it worked and for alternative way to make php recognize the module used in newer php, see http://emg.nysbc.org/documentation/leginon/bk02ch04s07.php under the section Check php information and Alternative approach if mrc module does not show up in info.php output
