h1. Install SSH module for PHP

This installation occurs on the web server.

h2. The ssh2 extension for php

First, install the following prerequisites:

|_.Name:|_.Download site:|_.CentOS yum package name|_.Fedora yum package name|_.SuSE rpm name|

|php devel |http://www.php.net |php-devel |php-devel| |

|libssh2 devel |http://www.libssh2.org |libssh2-devel (found in epel repo)|libssh2-devel| |

|SSH PECL extension |http://www.php.net/manual/en/ssh2.installation.php |- |php-pecl-ssh2 | |

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

h2. Download and compile the ssh2 extension

bq. 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.

# Go the website http://pecl.php.net/package/ssh2

# Download the latest version of ssh2:<pre>

wget http://pecl.php.net/get/ssh2-0.11.2.tgz</pre>

# Extract the tar ball<pre>

tar zxvf ssh2-0.11.0.tgz</pre>

# Go into the directory<pre>

cd ssh2-0.11.0</pre>

# Run phpize and standard make process<pre>

phpize

./configure

make</pre>

# Install the module:<pre>

sudo make install</pre>

# Add a ssh2.ini to your php ini folder:<pre>

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

</pre>

# Restart httpd:<pre>

sudo /sbin/service httpd restart</pre>

h2. Test if the module is working:

# 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

# search for the ssh2 module, you should see this section:

!ssh2box.png!

h2. Still having problems?

# 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)
