Stop the OBProxy process

1. Log on to the load-balancer and delete the IP address of OBProxy.

2. Log on to the sys tenant as the root user from OceanBase Client (OBClient).

3. Run the SHOW PROCESSLIST command to view connections and verify that OBProxy has zero connections.

4. Log on to the server where OBProxy is installed, run the following command in the command-line tool to view the status of the OBProxy process:

   ps -ef | grep obproxy | grep '^admin' | grep -v grep
   

   Note

   OBProxy is installed under the admin user. Therefore, you can use the '^admin' filter in the command.

4. Run the following commands to kill the processes associated with OBProxy.

   The ./bin/obproxyd.sh process is the daemon of OBProxy. It automatically starts the OBProxy process when the OBProxy process quits abnormally.
