Tighten the access rules for galera
Set a password for the 'root' db user and add an additional 'clustercheck' user to be used only by the resource agent. The password for this 'clustercheck' user is randomly generated via a heat parameter. Before this change the workflow to set up the database in the manifest is the following: - Step 1 -> Install all the basic galera packages and basic configuration - Step 2.a -> Create /etc/sysconfig/clustercheck with root and empty password - Step 2.b -> Start up galera-monitor xinetd service - Step 2.c -> Start pacemaker ocf resource (no root user has been created so there will be an empty password per default) - Step 2.d -> Wait for /bin/clustercheck to return success and then proceed with the other steps After this change the workflow is slightly more complex because there is a bit of a chicken and egg problem: - Step 1 -> Install all the basic galera packages and basic configuration - Step 2.a -> Create /etc/sysconfig/clustercheck with root and empty password unless the file does exists already and has a clustercheck user configured - Step 2.b -> Start up galera-monitor xinetd service - Step 2.c -> Start pacemaker ocf resource (no root user has been created yet, so there will be an empty password per default) - Step 2.d -> Wait for /bin/clustercheck to return success and then proceed with the other steps - Step 2.e -> Create clustercheck db user - Step 3/4 -> Create /etc/sysconfig/clustercheck with clustercheck user credentials - Step 5.a -> Update the sql root password on the each node (at this stage - Step 5.b -> Create /root/.my.cnf with proper credentials on all nodes Note that we cannot really create the root/clustercheck users right at step 1 because the db is not running yet (an approach that spawned mysqld on each node, created the users and shut it down, was tried but was much more complex and cannot work on updating existing setups) Given the new way of solving the root password issue, we also need to make sure that Step1 and Step2 are running on updates.
