Step 4: Start the Cloudera Manager Server and Agents

After you set up the Cloudera Manager database, start Cloudera Manager Server and Agents, and log in to the Cloudera Manager Admin Console. Then proceed through the installation wizard.

  1. Ensure that the Cloudera Manager and Cloudera Agents are set to load automatically post-installation, to avoid cases where the server is rebooted and the service won’t go up. Then start the services by performing the following steps:
    1. Run the following commands on the Cloudera Manager Server: 
      sudo systemctl enable cloudera-scm-server
      sudo systemctl start cloudera-scm-server
    2. Run the following commands on each of the Cloudera Manager Agent (either one by one or using ansible-playbook/clush on all the nodes remotely): 
      sudo systemctl enable cloudera-scm-agent
      sudo systemctl start cloudera-scm-agent
  2. Wait several minutes for the Cloudera Manager Server to start. To observe the startup process, run the following on the Cloudera Manager Server host: 
    sudo tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log
    When you see this log entry, the Cloudera Manager Admin Console is ready and you can stop the tail command:
    INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server.
    If the Cloudera Manager Server does not start, see Troubleshooting Installation Problems.
  3. In a web browser, go to http://<server_host>:7180, where <server_host> is the FQDN or IP address of the host where the Cloudera Manager Server is running.
  4. Log into Cloudera Manager Admin Console. The default credentials are:

    Username: admin

    Password: admin

After logging in, the installation wizard launches. The following sections guide you through each step of the installation wizard.
