Update Cloudera Manager

Update Cloudera Manager to specific version [5.4.5]

Take database backup.

If we are running a dedicated database which is recommended in production setup. then we need to take a backup of the DB as a precaution.
Assuming we are using a dedicated DB.

Stop Cloudera Manager Server, Database, and Agent

Shutdown cloudera manager server.
sudo service cloudera-scm-server stop
If cloudera manager is also running an Agent service.
sudo service cloudera-scm-agent stop
NOTE : If we are using a standalone/embedded database then we need to stop that as well.
sudo service cloudera-scm-server-db stop

Update repository to get the latest rpm.

Create a file cloudera-manager.repo with below contents.
# Packages for Cloudera Manager, Version 5.4.5, on RedHat or CentOS 6 x86_64
name=Cloudera Manager
copy cloudera-manager.repo to /etc/yum.repos.d/
$ sudo yum clean all
$ sudo yum upgrade cloudera-manager-server cloudera-manager-daemons cloudera-manager-agent
Check if all the installation was good.
$ rpm -qa 'cloudera-manager-*'
