OpsCenter 4.0 User Guide

Disabling SSL - tarball installations

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

By default SSL is turned off in OpsCenter. You would only need to perform this task if you have configured the agents on a cluster to use SSL earlier and now wished to turn SSL off.


  1. Open opscenterd.conf in an editor and add two lines to enable SSL.
    $ vi <install_location>/conf/opscenterd.conf
    use_ssl = false
  2. Restart the OpsCenter daemon.
  3. Reconfigure the agents.
    1. Log into each node in the cluster using ssh.
      $ ssh <user>@<node>
      Where <node> is either the host name of the node or its IP address and <user> is the userid on the node.
    2. Edit the address.yaml file, changing the value of use_ssl to 0.
      $ sudo vi <install_location>/conf/address.yaml
      use_ssl: 0
    3. Restart the agent.
      $ sudo <install_location>/bin/datastax-agent

If you do not want to edit all the node configuration files by hand, you can follow the agent installation procedure.

  1. Once opscenterd and all agents have been configured and restarted, verify proper connection via the dashboard.
