Prerequisites
- Root or sudo access to the machines where the agents will be
installed.
- The Cassandra or DataStax Enterprise cluster is up and running.
- OpsCenter is installed and configured.
- JMX connectivity is enabled on each node in the cluster.
Procedure
-
Add the DataStax repository to the
/etc/apt/sources.list.d/datastax.community.list file
(if you have already not done so).
$ echo "deb http://debian.datastax.com/community stable main" | \
sudo tee -a /etc/apt/sources.list.d/datastax.community.list
-
Add the DataStax repository key to your Aptitude trusted keys.
$ curl -L https://debian.datastax.com/debian/repo_key | sudo apt-key add -
Note: If you have any difficulty adding the key, use HTTP instead of
HTTPS.
-
Install the DataStax agent.
$ sudo apt-get update
$ sudo apt-get install datastax-agent
-
In address.yaml set
stomp_interface to the IP address that OpsCenter is using.
You might have to create the file.
$ echo "stomp_interface: <reachable_opscenterd_ip>" | sudo tee -a /var/lib/datastax-agent/conf/address.yaml
-
If SSL communication is enabled in
, use SSL in .
$ echo "use_ssl: 1" | sudo tee -a /var/lib/datastax-agent/conf/address.yaml
-
Start the DataStax agent.
$ sudo service datastax-agent start
