Make sure that gem install mysql -v '2.9.1' succeeds before bundling.

I am using RHEL 6. I also have a separate cookbook for mysql installation. I tried installing Mysql manually using the yum command.

I tried

yum install mysql-devel and then run the gem install mysql

still not working. Can anyone help me out.

Thanks

  • Maybe yum install mysql mysql-server mysql-devel ? Commented Aug 21, 2013 at 20:44

It sounds like you don't have a compiler. On a debian/ubuntu system, you can get everything you need to compile and build packages with:

sudo apt-get install build-essential

On Fedora/Red Hat I think it should be:

sudo yum groupinstall "Development Tools"

I tried the sudo yum command and got the following error This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. Setting up Group Process epel/group_gz | 237 kB 00:00 No packages in any requested group available to install or update
Did you try to register? access.redhat.com/site/documentation/en-US/…
i got the Development tools working .. still the mysql gem throws the same error.

Add the build-essentials cookbook to your runlist and configure it's "compiletime" attribute.

The following answer reports the same problem building the postgres gem
