Scenario
After the client is installed, you can use the shell command on the client in O&M or service scenarios, or use the sample project on the client during application development.
This section describes how to use the client in O&M scenario or service scenarios.
Prerequisites
- You have installed the client.
For example, the installation directory is /opt/client.
- Service users of each component have been created by the system administrator based on service requirements.
A machine-machine user needs to download the keytab file and a human-machine user needs to change the password upon the first login.
Procedure
- Log in to the node where the client is installed as the client installation user.
- Run the following command to switch to the client installation directory:
cd /opt/client
- Run the following command to set environment variables:
source bigdata_env
- If the cluster is in security mode, authenticate the user. For a normal cluster, user authentication is not required.
kinit Component service user
- Run the shell command as required.
