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

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

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.

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

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
```
```
[agents]
use_ssl = false
```
Restart the OpsCenter daemon.
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 install_location/conf/address.yaml
```
```
use_ssl: 0
```
3. Restart the DataStax Agent.
```
sudo install_location/bin/datastax-agent
```
After opscenterd and all DataStax Agents have been configured and restarted, verify proper connection through the Agent Status tab.
