Logging In to the Management Node¶
Scenario¶
Some O&M operation scripts and commands need to be run or can be run only on the active management node. You can identify and log in to the active or standby management node based on the following operations.
Checking and Logging In to the Active and Standby Management Nodes¶
Log in to FusionInsight Manager.
Choose System > OMS.
In the Basic Information area, Current Active indicates the host name of the active management node, and Current Standby indicates the host name of the standby management node.
Click a host name to go to the host details page. On the host details page, record the IP address of the host.
Log in to the active or standby management node as user root.
Identifying the Active and Standby Management Nodes by Running Scripts and Logging In to Them¶
Log in to any node where FusionInsight Manager is installed as user root.
Run the following command to identify the active and standby management nodes:
su - omm
sh ${BIGDATA_HOME}/om-server/om/sbin/status-oms.sh
In the command output, the node whose HAActive is active is the active management node (Master1), and the node whose HAActive is standby is the standby node (Master2).

Run the following command to obtain the IP addresses of the active and standby management nodes:
cat /etc/hosts
Example IP addresses of the active and standby management nodes:
127.0.0.1 localhost 192.168.0.30 Master1 192.168.0.24 Master2
Log in to the active or standby management node as user root.
