Problems with Rails 4 app into Bluehost

[Hernán Albano]

Hi all, 

I'm facing some problems launching my rails app hosted on bluehost. 

I think that the problem is the passenger version interacting with the rails 4 app but I'm not sure.

When I laucnh my app I get this trace: 

Ruby (Rack) application could not be started

These are the possible causes:

• There may be a syntax error in the application's code. Please check for such errors and fix them.
• A required library may not installed. Please install all libraries that this application requires.
• The application may not be properly configured. Please check whether all configuration files are written correctly, fix any incorrect configurations, and restart this application.
• A service that the application relies on (such as the database server or the Ferret search engine server) may not have been started. Please start that service.

Further information about the error may have been written to the application's log file. Please check it in order to analyse the problem.

Error message:

Could not initialize MySQL client library

Exception class:

RuntimeError

Application root:

/home5/barracam/rails_apps/admin/admin

I tried to run a rails 3 app and all works fine. What do you think about the problem?

Any help is really appreciated.

Hi André, how are you? 

I had run bundle install with no luck. Even had tried: bundle install --without development test

The issue seems to be related with the MySQL gem or something like that. I had read that the pool size could be the problem, and also see that the passenger version in Bluehost is old to work with rails 4. 

Any additional idea?

[Hongli Lai]

Bluehost is running a very old version of Passenger, one that we no longer support. Please contact Bluehost for any support instead.
