I have a Linux server I do not want to put a control panel on but I want to install client exec is there a tutorial on how to install it via ssh? I would put a control panel on it but I don't see the purpose when I have the server and only want to use one domain on it.
ClientExec is a PHP based script and it cannot be installed form SSH. If you are not installing any control panel, you will need to install necessary software to run your ClientExec script (i.e. Apache, PHP, MySQL and other).
Also, you will need to add necessary entry in your httpd.conf to add your website (which is running ClientExec) and other manual tasks (i.e. creating db, db user etc.)
