Upgrading DSE OpsCenter Package Installations
About this task
These steps provide information on upgrading to OpsCenter for package installs and restarting the opscenterd daemon.
|
Upgrade from OpsCenter 6.1 to the most current release of OpsCenter 6.5 before upgrading to OpsCenter 6.8. |
Prerequisites
Review Product Compatibility for information on OpsCenter compatibility with DSE.
|
Before upgrading, backup your OpsCenter keyspace, 6.8, if you anticipate, plan, or need to downgrade to an earlier version of OpsCenter. Downgrading OpsCenter is a very manual and case-specific process. If you require a downgrade, contact DataStax Support for assistance before proceeding. |
Additionally, view the compatibility table to ensure that OpsCenter is compatible with your version of DataStax Enterprise.
Procedure
-
Locate the
cluster_name.conffile. The location of this file depends on the type of installation:-
Package installations:
/etc/opscenter/clusters/cluster_name.conf -
Tarball installations:
<install_location>/conf/clusters/cluster_name.conf
-
-
If you previously configured the api_port (6.8) under the
[cassandra]or[storage_cassandra]headers in 'cluster_name.conf', then delete the entries.An existing api_port entry under the
[cassandra]or[storage_cassandra]headers prevents OpsCenter from starting. -
On the OpsCenter daemon host, run the appropriate command to update the packages:
-
Debian or Ubuntu
sudo apt-get update -
RHEL or CentOS
Yum automatically updates package lists when necessary.
-
-

Replace
version_numbershown in the example below with the version to which you are upgrading.-
Debian or Ubuntu:
sudo apt-get install opscenter=<version_number> -
RHEL or CentOS:
sudo yum install opscenter-<version_number>
-
-
If the package manager prompts you for options regarding
opscenterd.conf, then keep your currently installed version. -
Restart the OpsCenter daemon.
