Setting Up OpsCenter for a Single Node¶

Prerequisites¶

Before installing OpsCenter make sure you have met the following prerequisites:

• DataStax Enterprise is installed from a binary distribution and is running as described in or Installing and Starting the DataStax Enterprise Binaries as Root Installing and Starting the DataStax Enterprise Binaries as User.
• You downloaded and extracted the opscenter.tar.gz file.
• OpsCenter requires that the following software is installed:
  • Python 2.6+
  • OpenSSL 0.9.8 for CentOS 5.x, Debian, Mac OSX, OEL 5.5, RHEL 5.x, Ubuntu, and Windows
  • OpenSSL 1.0.0 for CentOS 6.x, OEL 6.1, and RHEL 6.x

To check for the software versions:

$ python -V
$ openssl version

You must use the exact version indicated above. For example, if you have a Ubuntu 11.10 system, the default OpenSSL is 1.0.0. Therefore, you must install OpenSSL 0.9.8:

$ sudo apt-get install libssl0.9.8

Note

Ubuntu 11.10 still shows 1.0.0e after installing OpenSSL 0.9.8.

Configuring OpsCenter and the OpsCenter Agent¶

1. Make sure the prerequisite software is installed.

2. Start OpsCenter:

   $ cd ~/opscenter-2.1

   $ bin/opscenter (in the background - default)

   $ bin/opscenter -f (in the foreground)

   Starting OpsCenter automatically installs the OpsCenter agent on the same machine as the DataStax Enterprise server and OpsCenter.

3. Set the agent to localhost:

   $ cd ~/opscenter-2.1/agent
   $ bin/setup localhost
   

4. Start the agent:

   $ bin/opscenter-agent (in the background - default)

   $ bin/opscenter-agent -f (in the foreground)

5. Launch OpsCenter from a browser using the following URL:

   http://<opscenter_host>:8888

6. In the Welcome to DataStax OpsCenter dialog box, enter localhost in the Cluster Hosts/IP field, and then click Add Cluster.

   The OpsCenter Dashboard is displayed.

   
   
   

To deploy OpsCenter agents to multiple nodes or to install OpsCenter using a packaged distribution, see OpsCenter documentation.
