Error when changing the root password in TiDB
First execute:
tiup cluster edit-config tidb-test
Then execute:
tiup cluster reload tidb-test
The TiDB cluster is deployed on a single machine. SSH is interconnected.
There shouldn’t be any issues with the process of changing the password, so why is this error being reported? I can’t find the reason for a while.
Don’t change it like this. Directly log in to the TiDB server machine, modify the TiDB server configuration file tidb.toml, then use systemctl to restart the TiDB service, and finally log in locally to change the password.
The official documentation provides instructions on how to reset the password if you forget it, not like what you mentioned.
Modifications should be possible, but the original mutual trust should be re-established.
According to the official documentation, make modifications.
According to the official modifications, there are no issues.
You can refer to my article Column - Forgot the root password for TiDB? Here’s a trick to solve it | TiDB Community
Got it, to summarize, it’s still similar to the modification method of MySQL.
