If you’re trying to install ThoughtWorks’ Go Server on CentOS (or indeed any Linux variety), you might run into a problem where it says you need JDK installed. Indeed, even if you have OpenJDK installed it may continue to complain.
This is because they have not officially approved OpenJDK yet, so your two options are to a) installed the actual JDK or b) to install OpenJDK to at least the version required (1.6 at time of writing) and then force the installer to ignore dependences. This can be done using the following command.
rpm -i --nodeps go-server.rpm
Providing you already have OpenJDK installed, this should work fine.
