Disabling SSL - tarball installations

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

opscenterd.conf

The location of the opscenterd.conf file depends on the type of installation:

Location	Package	Installer (GUI or text mode)		Tarball
Location	Package	Service	No-service	Tarball
/etc/opscenter/opscenterd.conf	X	X
`install_location`/conf/opscenterd.conf			X	X

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

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.

Procedure

Open opscenterd.conf in an editor and add two lines to enable SSL.
```
$ vi install_location/conf/opscenterd.conf
```
```
[agents]
use_ssl = false
```
Restart the OpsCenter daemon.
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.

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