Manually deploying DataStax Agents from RPM

Installs DataStax Agents on Linux nodes using Yum 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 Yum repository in the /etc/yum.repos.d/datastax.repo file.
```
[opscenter]
name = DataStax Repository
baseurl = https://rpm.datastax.com/enterprise
enabled = 1
gpgcheck = 0
```
Set gpgcheck=1 to perform a GPG signature check.
If you have enabled signature verification (gpgcheck=1), import the repository key:
```
sudo rpm --import http://rpm.datastax.com/rpm/repo_key
```
Install the DataStax agent:
```
sudo yum install datastax-agent
```
If you are using an earlier version of OpsCenter, add the supported version to the command:
```
sudo yum install 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 address.yaml:
```
echo "use_ssl: 1" | sudo tee -a /var/lib/datastax-agent/conf/address.yaml
```
Start the DataStax agent:
```
sudo service datastax-agent start
```
