Procedure

In a terminal for both 32- and 64-bit systems:

  1. 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
  2. If you have enabled signature verification (gpgcheck=1), import the repository key:
    sudo rpm --import http://rpm.datastax.com/rpm/repo_key 
  3. Install the DataStax agent.
    sudo yum install datastax-agent
  4. In address.yaml, 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
  5. 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
  6. Start the DataStax agent.
    sudo service datastax-agent start
