Disabling SSL/TLS for OpsCenter and Agent communication - Tarball Installations


By default, SSL is turned off in OpsCenter. You only need to perform this task if you have previously configured the DataStax Agents on a cluster to use SSL and now want to turn SSL off.


  • Tarball installations: install_location/conf/address.yaml


  • Package installations: /etc/opscenter/opscenterd.conf
  • Tarball installations: install_location/conf/opscenterd.conf


  1. Open opscenterd.conf in an editor and set the value of the use_ssl option to false to disable SSL.
    vi install_location/conf/opscenterd.conf
    use_ssl = false
  2. Restart the OpsCenter daemon.
  3. Reconfigure the DataStax Agents.
    1. Log in to each node in the cluster using ssh.
      ssh user@node
      Where user is the user ID on the node, and node is either the host name of the node or its IP address.
      sudo vi install_location/conf/address.yaml
      use_ssl: 0
    3. Restart the DataStax Agent.
      sudo install_location/bin/datastax-agent
  4. After opscenterd and all DataStax Agents have been configured and restarted, verify proper connection through the Agent Status tab.
