[Myexperiment-discuss] Sharing experience about a myExperiment local installation

[Olivier Hamon]

Hello everyone,

After spending some time on a myExperiment local installation, I would 
like to share the issues I encountered and the solutions I found to make 
myExperiment work. Some issues may be due to my misunderstanding about 
the instructions, and I guess there are certainly better solutions!

My software specifications are the following (a bit more up-to-date than 
in the instructions):
 * Debian squeeze
 * Apache 2.2.14
 * MySQL Version 14.14, Distribution 5.1.41
 * Java 1.6.0

I have used the instructions from 
http://wiki.myexperiment.org/index.php/Developer:UbuntuInstallation, as 
available on March 10.

Looking at the different instruction steps, here are the actions that I 
have had to add.

 - Before installing all the GEMs required by MyExperiment (gem install 
builder cgi_multipart_eof_fix daemons dsl_accessor fastthread gem_plugin 
hoe json mime-types mongrel mongrel_cluster needle net-sftp net-ssh 
openid_login_generator RedCloth ruby-yadis solr-ruby xml-simple 
libxml-ruby oauth ruby-hmac openurl --include-dependencies), the 
following command was required:

>> gem update --system

   I don't remember all the details, but for instance, I was not able 
to install hoe.

   I also added:

>> gem install rubyzip

   otherwise I got problems later.
 - From the rake commands, I had to do several things:

   rake db:migrate => I got many duplicate errors during the database 
installation:
      * 'create table' duplicates in files 
db/migrate/{006,009,022,049,050,076,089}... => I removed the files
      * 'alter table' duplicates in files db/migrate/{023,069,070}... 
=> I commented the involved lines
      * 'index' duplicates in files db/migrate/{075,086,087}... => I 
commented the involved lines
      without those modifications, rake was aborted.
      I also changed production environment into development (3 times 
in the migrate.sh file)

   rake solr:start => rake was aborted for some mysterious reasons, and 
I applied a patch found there: 
http://redmine.ruby-lang.org/attachments/835/net_http_socket_close.patch

   ./resolr.sh => myExperiment is in production mode by default, and I 
assume the database installation is in development mode (otherwise I get 
error messages there). Then I changed myExperiment into development mode 
in config/environment.rb and resolr.sh files

   ruby script/server => before starting the script and in order to 
make it work, I had to do the following installation:

>> apt-get install mongrel

Now, myExperiment is working and I'm going to work on the myExperiment 
usage itself :)

Anyway, I would be glad to know if there are better solutions to those 
issues.

Best,
Olivier
