This article mainly introduces the implementation of sdbstart start data node error how to do, has a certain reference value, interested friends can refer to, I hope you read this article after a great harvest, the following let Xiaobian take you to understand.

[Problem Description]

Execute sdbstart to start the data node and report error:

$ sdbstart -p 12020

ERROR: Start [/opt/sequoiadb/bin/../ conf/loca/12020] failed, rc: 137(Unable to listen the specified address)

[Solution]

1. According to the error message, the failure to start the node is caused by a monitoring error. Check the situation of port 12020 and find that this port is occupied by TCP connection.

2. It is recommended that the port number of the data node should not be within the local open port range, otherwise it is easy to be temporarily assigned as the TPC connection port, resulting in port collision.

3. The local open port range can be viewed in/proc/sys/net/ipv4/ip_local_port_range. It is not recommended to set the data node port number in this port range.

Thank you for reading this article carefully. I hope that Xiaobian's shared article "How to do wrong when executing sdbstart data node" will be helpful to everyone. At the same time, I hope that everyone will support you a lot, pay attention to the industry information channel, and more relevant knowledge is waiting for you to learn!
