Installing mx
These are somewhat brief and should evolve as more people attempt to install. Feel free to add questions right here. Details about one person's experience with installing mx on his local machine (for development) are posted separately.
At present you'll need to have a fairly good understanding of Rails to develop mx, and modify it for you needs. As the project develops we hope to continue to minimize this dependency, including for instance installer scripts, and coding how-tos. If you're seriously considering supporting a mx installation in your lab or workplace at this moment you should have an intermediate to advanced programmer/server admin in your team. Note that because one instance of mx can serve multiple projects a single admin may be able to support a team of labs, so resources could be shared in that sense.
Required Software
MySQL
- You need at least MySQL 4.1.14 to install the tables. 4.1.10 and previous will load, but several queries (mostly Matrix related) will not work. We have not investigated whether they can be modified to work with 4.1.10 or earlier. MySQL 5.n is in use on development and production servers. Its easiest to install the community addition with the startup item too, then reboot. You'll want to secure your mysql installation.
- There are many examples of how to install and secure MySQL on your machine available on whe world-wide web. If you are using OS X chances are you have a copy installed already (it will need configuration if you haven't already done so).
Ruby
- If you don't already have ruby you can find more about it here. We run mx under 1.82 or 1.84. We recommend building it from source. Get it the source here.
RubyGems
Its easiest to install several Ruby packages (including Rails) through the Ruby package manager RubyGems.
Rails
Source is now posted for 2.02.
Do:
gem install rails --include-dependencies
More information on installing Rails may be found at the URL above. Production is now using 2.0.2.
You'll also need RedCloth, a simple markup language that is used in various places (sudo these on OS X).
gem install redcloth
and the mysql adapter
gem install mysql
and ruby-debug
gem install ruby-debug
ImageMagik (optional)
- NOTE: This is optional, and not required for MorphBank images.
- The tools 'convert' and 'identify' must be in your PATH.
Platform Specific Notes
OS X
- Very good instructions on installing ruby, rails, mysql, mongrel (a webserver for ruby on rails) and subversion on Mac 10.4 PowerPC or Intel machines is here http://hivelogic.com/articles/ruby-rails-mongrel-mysql-osx/. In these instructions, Capistrano does not to be installed nor the 'MySQL Native Bindings Gem.' The instructions install Ruby version 1.8.6 which works with at least mx 0.1.1379 and later.
gem install rails --include-dependencies
- These notes: one person's experience with installing mx also include Mac install instructions, but these do not include Ruby install instructions.
- You should have Apple's develop tools installed before installing mx. Later versions of OS X come with it installed, if you can do
gcc -v
and see 3.n or 4.n you're probably ok.
- You may have to use 'sudo' in front of your commands when installing, like
sudo gem install rails --include dependencies
- You need to be running Ruby version 1.8.2 or higher (tested on 1.8.2)
- OS X updates **WILL** break your installation by (re)installing Ruby to /usr/bin. Their version (at least in 10.3.9) is incompatible with mx. The easiest way to get around this is to simply rename the OS X version ruby in /usr/local/bin to something like ruby_old like this:
cd /usr/local/bin mv ruby ruby_old
- Test your version of ruby at the path by entering
ruby -v
- Some instructions for compiling ImageMagick and its dependencies can be found here. Although the instructions lead up to installing the rmagick ruby gem, that step should not be done because it is not necessary for mx's image handling to work. Mx only requires that the commands identify and convert be accessible from your command prompt, which these instructions without the gem install step will do.
x86 (Windows 2000/XP)
- you will need to install the ruby-debug gem (the latest version doesn't? have a pre-compiled binary, this version does)
gem install ruby-debug -v 0.9.3
- The db/rake tasks for rebuilding are apparently borked at present matt 19:40, 16 January 2007 (CST)
*nix Specific Notes
The following instructions were tested on Kubuntu 7.04 and may require some modifications according to the distribution you use.
You have to install the library libmysql-ruby:
sudo apt-get install libmysql-ruby
Installation
Basic steps
- Install the required software (see above).
- Download the mx source.
- Build the database(s).
- Configure the database for startup.
- Configure your folders
Detailed installation steps
Download mx source
Its always worthwhile contacting the developers to see if you have the latest version of the source. SVN access will happen, likely in 08, until then give us a 'holler.
- Get it from [Sourceforge] *OR*
- Check out a copy via SVN (only available to developers at present)
Build the database
The easiest way to install the database is to open a terminal or command prompt and navigate to the /db folder at the root of the mx code (you should see the tables.sql file there). Once there logon to mysql as an administrator. The process to install from scratch will look like something like this (don't forget the ';' for mysql commands):
cd <path_to_rails>/db mysql -u root -p <enter password> create database mx_development; use mx_development; source tables.sql;
Build the production databases the same way:
create database mx_production; use mx_production; source tables.sql;
If you have access to a master copy of the data from production (talk to your administrator to see if this is possible) you'll not need to follow the instructions below, but do:
cd <mx root>/db rake restore_last file=<dumped production data>
Or use mysql. Does not matter where the *.sql file is but you must be in that folder when prompt mysql (or you must define the path to the *.sql file):
use mx_development; source <your file like 2007_01_10_173343.sql>;
note: you must use your -u root
Add an administrator to the mx tables
These steps all require that you are using the MySQL client
mysql -u root -p <enter password>
You'll need to add a MySQL account so that the app can access the database:
GRANT ALL PRIVILEGES ON mx_development.* TO 'mx'@'localhost' IDENTIFIED BY 'MmmXxx';
A single user with administrator privileges will have to be manually added to the 'people' tables prior to using mx. Once this user is added additional users can be added from the mx interface.
use mx_development; insert into people (first_name, last_name, login, password, is_admin, creates_projects) values ('joe', 'smith', 'jsmith', sha1('foosomepwdbar'), 1,1);
- IMPORTANT - you must wrap 'foo' and 'bar' around your password in the above line. In the example above the password for 'jsmith' is 'somepwd' #
Add a root taxon name to your tables
While in the MySQL client you'll also want to add a root node to your taxonomic names hierarchy (assumes the admin you created has id 1).
insert into taxon_names (name, display_name, l, r, creator_id, updator_id) values ('root', 'root', 1, 2, 1, 1);
To start adding real taxa after you create a project make this root taxon visible via the visibility view in the "Taxon names" tab. Then the root will available as the parent of the highest taxonomic level included in your taxa list.
Check/update the environment.rb file
Check the
/config/environment.rb
file. At the bottom you'll some variables under the header Local Configuration. Some past versions of the source have the variables incorrectly set like so:
HOME_SERVER = foo.bar.com
or
NOTIFICATION_RECIPIENTS = foo@bar.com
When they should be like:
HOME_SERVER = 'foo.bar.com'
and
NOTIFICATION_RECIPIENTS = 'foo@bar.com'
You may also change the various FOO_PATHs if your local configuration is setup differently.
You'll need to grab GoogleMaps API keys and add them for BOTH of:
GMAPS_KEY_PRODUCTION GMAPS_KEY_DEVELOPMENT
Specific to *nix systems: check the path of your MySQL socket
By default, the path of mysql.sock is set to
/tmp/mysql.sock
However, several distribution does not use this path. To change it edit the file
config/database.yml
and replace the 3 occurrences of
socket: /tmp/mysql.sock
by your actual path. For instance in Ubuntu
socket: /var/run/mysqld/mysqld.sock
Files and images uploaded to mx are stored in /public/files
If you are on a PC create the following folders in <root of mx install>/public
files files/images files/images/big files/images/medium files/images/original files/images/thumb files/pdfs files/datasets
On a *nix system (including OS X) you'll need the same structure, but note that you can also use a symbolic link to keep your images, pdfs, and datasets elsewhere.
Usage (development mode)
Using the server/application
To test/develop in development mode navigate to the root of your installation and type
ruby script/server
Open a web browser and browse to
127.0.0.1:3000
You should see a login page. If you see the mx page but no login fields then you have not correctly added your administrator user.
Once logged in navigate to
127.0.0.1:3000/admin
to create new projects.
You can also navigate to
127.0.0.1:3000/account/signup
to add regular users.
Rebuilding the tables
If you've downloaded a new version of mx, or have a new copy of the tables you can rebuild the tables several ways.
Using rake
Navigate to /db and do
rake --tasks
You'll see a list of options that you can run in that directory. The dumped data goes into /dumps.
To rebuild the tables with the *current* data do this
rake reload
So if you have acquired a copy of data from someone else you can do something like this:
rake restore file=<your file like 2007_01_10_173343.sql>
Note that its assumed that the data is in /dumps.
Using SQL statements
If you just want to rebuild the tables (*prior* to their being any data, all data will be LOST via this method) you can repeat the building commands:
cd <trunk>/db mysql -u <username, e.g. root> -p drop database mx_development; create database mx_development; use mx_development; source tables.sql;
If you have data that you want to maintain then do a
rake dump_data
prior to the sequence above. Then repeat the rake restore.
Usage (production mode)
<under construction>
Production installation follows, for the most part, the same installation process as above. See the Rails homepage for setting up the server. Note that only users with accounts can see data in a clean installation of mx, i.e. you must manually configure the installation to make data available to the public.
If you plan to set up a production installation of mx, it would be a good idea to read chapter 27 of Agile Web Development with Rails, second edition.
Configuration: You will have to change some values in config/environment.rb, such as HOME_SERVER, HELP_WIKI and replacing the emails in
ExceptionNotifier.exception_recipients = %w(joe@schmoe.com bob@gmail.com)
