Upgrading DataStax Agents
Upgrade the DataStax Agents on each node in the managed clusters after restarting the upgraded OpsCenter daemon.
For more information, see Installing DataStax Agents.
Upgrading DataStax Agents automatically from the OpsCenter interface
If DataStax Agents require upgrading, use the OpsCenter interface to automatically upgrade them.
In OpsCenter versions 6.1 and later, the OpsCenter and agent compatibility awareness feature notifies you of any potential features that might not operate on older agent versions.
- In the OpsCenter interface, click
cluster_name >
Nodes, and then click the
Agents tab.
A message displays indicating the number of DataStax Agents running an earlier version that might have incompatibilities with OpsCenter 6.7.5.
- In the DataStax Agents Status View of the
OpsCenter interface, click Upgrade all agents.
The Set Up Agents window appears.
- Choose whether to Install or start agents automatically or Install agents manually.
Upgrading DataStax Agents manually from tarballs
- Copy the new agent.tar.gz file to all nodes in the
cluster:
scp agent.tar.gz node_name
- Extract the
tarball:
tar -xvf agent.tar.gz
- Copy the following files in the tarball from the old DataStax Agent tarball
directories to the new
ones:
scp -r old_tarball_directory/conf/* new_tarball_directory/conf/*
scp -r old_tarball_directory/ssl/* new_tarball_directory/ssl/*
