What operating system are you using if you can’t get the system info?

Can you SSH into these machines at 1.1.1.83:789?

It feels like either the username or password is incorrect, or there is a permissions issue. If possible, it’s best to use -u root during installation.

Every time I encounter an SSH problem, I revisit this:

If you can’t log in, how can the OS detection above be completed?

  • Detecting node 1.1.1.34 OS info … Done
  • Detecting node 1.1.1.62 OS info … Done
  • Detecting node 1.1.1.63 OS info … Done
  • Detecting node 1.1.1.83 OS info … Done
  • Detecting node 1.1.1.84 OS info … Done

This error is likely due to the installation package not being downloaded. Try a few more times, or check the network of each host.

OS=Linux, ARCH=amd64

Does this file need to be downloaded remotely? Can it be made into an offline package?

Try running tiup cluster check to see if it’s an SSH login permission issue.

This error occurred during the check! Thank you.

What configuration information do you need to look at? TiKV or PD?

What deployment method did you use?

14
| username: 月明星稀 | Original post link

When deploying with tiup, an error occurs when executing tiup cluster check.

It looks like the same issue, both are permission issues.

16
| username: 月明星稀 | Original post link

I have configured this in the /etc/sudoers file:
tikvadmin ALL=(ALL) NOPASSWD: ALL

Moreover, if it’s due to the lack of SSH permissions, logically the OS detection should also fail. How could it succeed then?

  • Detecting node 1.1.1.34 OS info … Done
  • Detecting node 1.1.1.62 OS info … Done
  • Detecting node 1.1.1.63 OS info … Done
  • Detecting node 1.1.1.83 OS info … Done
  • Detecting node 1.1.1.84 OS info … Done

You can use this method to verify.

You see, the link is the same. The first step does not report an error, but the second step does.
It should be that the required permissions are different.

You’re not saying that each node has a different user, right? There aren’t also tidbadmin and pdadmin, are there?
