1. Use netstat -tulpn to view port usage

netstat -tulpn

2. Find the occupied port (confirm that the service corresponding to the port is the service to be enabled soon)

# 以8006端口为例
netstat -tulpn | grep 8006

return field

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name 

3. Release the corresponding port

# 6012为对应的PID
kill -9 6012

4. Restart the service successfully
