The installer is designed to be run on servers that have a basic operating system installed, but no more than that. If you are setting up a new ZendTo server, this is what you want. Many sites now have a standard "blank template", on top of which all their services are built. This template usually contains settings for features such as authentication, security, logging and backups. The installer should work well on these types of systems.
The installer will automate (almost!) the entire process is installing ZendTo on to a blank minimal server installation.
Note: If you are already running ZendTo on the server, you can safely run the installer (and should) as and when major new features are added, as it may need to update your PHP environment or other packages to versions required for the new features.
It talks to you along the way, asks if you want to do each of the 7 steps, and asks you to confirm settings it finds. It pauses quite a bit so you can see what it's doing, giving you the chance to stop it temporarily (Ctrl-S) to read what it's done before you continue (Ctrl-Q), or stop it completely (Ctrl-C). If you stop it completely, you can just run it again to continue where you left off.
It is modular, so you can run each of the 7 parts alone. You may want to do this if, for example, you are using SELinux and move the drop-offs store onto a different filesystem, so need to re-apply the SELinux filesystem labels.
The parts are:
The installer has been developed and tested on all of the following:
It is fully compatible with SELinux, AppArmor and the systems' firewalls, and will configure each appropriately.
There are 2 little things the installer does not currently do:
Simply download and run the latest version of the installer.
Note: If you are upgrading from anything earlier than version 5.00, read the upgrade notes before you start. In short, save yourself a lot of trouble and build a new server from scratch using the ZendTo Installer: it will be quicker and easier.
Note: If you are upgrading from any version earlier than 5.09, download and run the installer to upgrade your system, as a newer version of PHP is required and will be installed for you.
Only install this package if you know what SAML is and actually need it. Most ZendTo sites don't need it.
