Bamboo installation -Failing to connect to database

venkat_vhvsh1

Hi 

We are running on bamboo 8.2.5 and planning to create a multinode datacenter environment .when we try to install bamboo on new node it is not allowing further from the database connection and prompting that "Database contains existing data ".Can anyone suggest best way to deal with 

1.for shared directory created an EFS and mounted on <bamboo-home>-->datacenter-->shared path.

2.Instances are placed in AWS.

3.And what would be the recommended load balancer to configure with both the nodes.

Hello @venkat

Additional Bamboo cluster nodes should not be configured from scratch like you are.

Whenever you add a new node to a Bamboo cluster, that node will remain idle, trying to acquire a lock on the DB and will not start if an active node is already running. The startup process on the standby node will only happen when the active node times out writing to the lock table on the DB.

So, in a nutshell, you need to:

• Install and configure the first Bamboo active node, the Database, Home and Shared home folders
• Start the first Bamboo active node
• Install the Bamboo binaries on the standby node(s)
• Configure an exclusive Bamboo home
• Mount the shared home folder (via NFS between the nodes)
• Start the additional node(s)

If you wish to test the standby node, you will have to shut down the active node and wait up to 5 minutes for the standby node to begin the takeover process.

Please check the following documentation on how to set a standby node in a Bamboo cluster:
