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/ssh2-0.11.0.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)
