Original topic: tiup cluster reload 失败

| username: TiDBer_bOR8eMEn

[TiDB Usage Environment] Production Environment
[TiDB Version] 5.2.3
[Reproduction Path] Modified SSH port to 8822, but the ssh_port in tiup cluster edit-config is 22. After changing it to 8822, tiup cluster reload is required for it to take effect. However, since my SSH is 8822, the reload fails. I want to know if there are other methods to make the configuration parameters take effect besides reloading on the control machine.

Modifying the SSH port for each host and global SSH port correctly should be sufficient :thinking: No need to reload.

Looking at your configuration, you have set an SSH port for each component. So, go to each component, change the SSH port in the config, then use systemctl to restart it, and then reload it on tiup.

The question is that I don’t want to change the SSH port in the config file now, I just want to change the configuration file. Is there any way to do this?

It seems possible.

Other components have all run successfully, but the reload of these three TIDB instances failed.

Are you still getting an error with the scp file transfer? Have you tried doing it manually?

Is it necessary to redistribute the component configuration files? There’s no record of the SSH port information here, right? Can someone test this?

| username: TIDB-Learner | Original post link

Can you test the scp command on the control machine to see if you can copy files to each instance machine?

Check the configuration information.

Take a look at the configuration file.

Also change the SSH port in the cluster configuration file.

Change the SSH port in the configuration?
