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

To disable SSL for package installations, modify the OpsCenter configuration file and restart OpsCenter.

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

opscenterd.conf

The location of the opscenterd.conf file depends on the type of installation:
  • Package installations: /etc/opscenter/opscenterd.conf
  • Tarball installations: install_location/conf/opscenterd.conf

address.yaml

The location of the address.yaml file depends on the type of installation:
  • Package installations: /var/lib/datastax-agent/conf/address.yaml
  • Tarball installations: install_location/conf/address.yaml

Procedure

  1. Open opscenterd.conf in an editor and set the value of the use_ssl option to false to disable SSL.
    sudo vi /etc/opscenter/opscenterd.conf
    [agents]
    use_ssl = false
    
  2. Restart the OpsCenter daemon.
  3. Reconfigure the DataStax Agents.
    Tip: If you do not want to manually edit all of the node configuration files, follow the procedure to install DataStax Agents automatically.
    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.
    2. Edit the address.yaml file, changing the value of use_ssl to 0.
      sudo vi /var/lib/opscenter/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.
