AWS Beanstalk Ruby Passenger, Solutions of Rjb Installing and 504 Gateway-Timeout

| Comments

Environment: AWS Beanstalk, 64bit Amazon Linux 2015.03 v1.4.1 running Ruby 2.1 (Passenger Standalone)

Project: Rails

The server had installed java-1.7.0-openjdk, and JAVA_HOME = /usr/lib/jvm/jre

There are to issuses:

  • gem install rjb, can’t find the floder /usr/lib/jvm/jre/include 
1
2
3
4
5
6

# we should install java-1.7.0-openjdk-devel
packages:
  yum:
      git: []
        java-1.7.0-openjdk-devel: []
...
  • 504 Gateway-Timeout, when the request invoke some method depend RJB

I had found a paragraph: http://xsen.iteye.com/blog/440675

The Reason is rjb, he said, and the solution is, in，passenger_ruby配置项下添加一行设置:

  • if using nginx, add this code in passenger_ruby config, rails_spawn_method conservative;
  • if using apache, add this code in PassengerRuby config, RailsSpawnMethod conservative

and I found s syntax code used for AWS Beanstalk, that is https://gist.github.com/luoguanzhong/bb684c59dfbe9ae02022.

Summary：You should login the server and see where the package install, and which it install. This could be help you quickly find the right solution.
