Manually deploying DataStax Agents from Debian

Installs DataStax Agents on Linux nodes using APT packages.

Prerequisites

opscenterd.conf

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

address.yaml

The location of the address.yaml file depends on the type of installation:

End User License Agreement (EULA). By downloading this DataStax product, you agree to the terms of the EULA.

In a terminal:

Add the DataStax repository to the /etc/apt/sources.list.d/datastax.sources.list file (if not already done):

echo "deb https://debian.datastax.com/enterprise \
stable main" | \
sudo tee -a /etc/apt/sources.list.d/datastax.sources.list

Add the DataStax repository key to your Aptitude trusted keys:

curl -L https://debian.datastax.com/debian/repo_key | sudo apt-key add -

Install the DataStax agent:
```
sudo apt-get update
```
```
sudo apt-get install datastax-agent
```
If using DSE 5.1 or earlier, you must install an earlier version of the DataStax Agent. See DataStax OpsCenter compatibility with DSE.
```
sudo apt-get install datastax-agent datastax-agent=6.8.version-1
```
In DataStax Agent configuration, set stomp_interface to the IP address that OpsCenter is using. You might have to create the address.yaml file.
```
echo "stomp_interface: reachable_opscenterd_ip" | sudo tee -a /var/lib/datastax-agent/conf/address.yaml
```
If SSL communication is enabled in opscenterd.conf, use SSL in DataStax Agent configuration:
```
echo "use_ssl: 1" | sudo tee -a /var/lib/datastax-agent/conf/address.yaml
```
Start the DataStax agent:
```
sudo service datastax-agent start
```
