wiki:intro_to_MFPL_hosting

This page explains some things about the MFPL servers and how to use MFPL hosting tools to create and manage websites. First draft by Patrick Gibbs in December, 2012.

First, appreciation for the MFPL support team! These fantastic humans do much of the nitty-gritty work of keeping this hosting infrastructure running. Learn more about the support team and see who's on it (though the list is a bit outdated) at Support Team.

So that you get an idea of why I find certain things seem worth mentioning about MFPL hosting -- my experience (says Patrick) includes the following:

  • setting up a Drupal + CiviCRM + Ubercart instance on cheap ($5/month) shared hosting.
  • administering a Moodle installation via the web interface.
  • doing basic command line work in GNU/Linux on my laptop.
  • writing a shell script once, and refining it.
  • playing with XAMPP when I used a Mac.

I had very little experience with SSH, and had never used IRC. I joined May First / People Link in August 2012.

Understanding May First servers

Start with the Members' Control Panel:

On previous hosting, I used cPanel. Here, there's custom software called red that runs a custom control panel. Look around and see what's possible. Things to notice:

  • On each page there's a line on the right side that says something like " Your primary host is: marx.mayfirst.org (216.66.23.57)". Knowing this enables connecting to the server via ssh (more on that later).

Each website is a "hosting order": I currently have two hosting orders: one for my personal website, and one for an organization whose website I manage. Hosting orders are made automatically (I think, although maybe the

Connecting via ssh or ftp:

There are other pages that explain this in more detail (to do: find them and link to them). I do this:

$ ssh patrickgibbs@marx.mayfirst.org

Wondering which server your site lives on? (In the command above, patrickgibbs is on marx.) Look in the Members' Control Panel (see section above).

I use Filezilla for FTP, and the connection details are the same as for ssh.

Welcome to your new /home:

Once logged in via ssh or ftp, you can look around and probably see something like this:

0 patrickgibbs@marx:~$ 

You might not have.drush, .emacs.d, or .zshrc until you use emacs, drush, or zsh.

Things to notice:

  • .monkeysphere has something to do with SSH fingerprints and encryption keys, I think. I haven't investigated yet. (to do: link to page about ssh connecting and fingerprints)
  • the website directory patrickgibbs.mayfirst.org is a symlink (symbolic link) that points up a few directories, and right now I'm already inside it, in my home folder, ~.

Let's look inside that website directory:

0 patrickgibbs@marx:~$ cd ../..

backups

I don't know what's in here. Probably backups... of what?

MySQL database backups so far. How did they get here? What's the schedule for backups?

bin

Don't know when I would use this.

cgi-bin

I know this has something to do with websites. I've seen cgi-bin in URLs at other websites. Beyond that, I don't know. It's empty.

include

This directory is accessible by the www-data user (the Apache web server user, although most stuff gets executed by your user, not by www-data or some other Apache user). This is the place to put things that you want accessible by that user -- so far, the only thing I've put there is a .htpasswd file for a Trac instance. Looks like php.ini lives here too, and I remember editing that file a few times during past projects on other servers.

This has something to do with the Members' Control Panel. I haven't touched anything in here, and it looks like I don't have permissions to anyways.

users

This is like home on my laptop -- it has a directory for each user, and when you login you arrive in that directory by default, for me users/patrickgibbs is the ~ directory. We already looked inside.

web

This is where websites live! On those $5/month cPanel hosts I've used, this directory was called public_html or www. This starts out empty.

future changes to this page

  • add links to the participate page and the "beginners instructions" page
  • add a section about how to ask questions, or link to an explanatory page if one exists.
  • add more detailed explanation of Members' Control Panel, with screen shots, and responses to questions like "Where is Fantastico?" (or does a page like that already exist?)
