Prerequisites
- 2 CPU cores
- 2 GB of RAM available to OpsCenter
Permission and software requirements:
- Yum package management utility.
- Latest build of a TCK (Technology Compatibility Kit) Certified OpenJDK
version 8 or Oracle Java SE Runtime Environment 8 (JRE or JDK). Earlier or later
versions are not supported. See installing the OpenJDK or Oracle
JDK.Attention: Although Oracle JRE/JDK 8 is supported, DataStax does more extensive testing on OpenJDK 8 starting with DSE 6.0.3. This change is due to the end of public updates for Oracle JRE/JDK 8.
- DataStax recommends using a recent version of one of the major web browsers. OpsCenter does not support Internet Explorer or Microsoft Edge.
Procedure
In a terminal window:
-
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
Note: Set the gpgcheck=1 to perform a GPG signature check. -
If you have enabled signature verification (
gpgcheck=1
), import the repository key:sudo rpm --import https://rpm.datastax.com/rpm/repo_key
-
Install the OpsCenter package:
sudo yum install opscenter-6.5.8
If you are installing an earlier version of OpsCenter, add the supported version to the command:
sudo yum install -y opscenter-6.5.version
For most users, the out-of-box configuration should work just fine. If necessary, you can configure OpsCenter for your environment.
-
Start OpsCenter:
sudo service opscenterd start
-
Connect to OpsCenter in a web browser using the following URL:
