Chapter 3. Accessing the high availability environment
You can access and investigate specific HA nodes from the undercloud.
Procedure
- In a running HA environment, log in to the undercloud.
Change to the stack user:
# sudo su - stack
To access and investigate an undercloud node, get the IP address of the node from the undercloud:
(undercloud) $ source ~/stackrc (undercloud) $ openstack server list +-------+------------------------+---+----------------------+---+ | ID | Name |...| Networks |...| +-------+------------------------+---+----------------------+---+ | d1... | overcloud-controller-0 |...| ctlplane=*10.200.0.11* |...| ...
To log in to one of the overcloud nodes, run the following commands:
(undercloud) $ source ~/overcloudrc (overcloud) $ ssh [NODE_NAME]@[NODE_IP]
Replace the name and IP address with the actual values from your deployment.
