Password-free configuration has been set
Is the SSH port 22022? Is the SSH port configured as 22022 in topology.yaml?
The configuration is all 22022.
A relatively simple way is to have the same password for all machines. There’s no need to configure passwordless login either.
In my environment, I use LDAP accounts to log in. Every time I deploy, I manually create a tidb user on the control machine, and there’s no need to create it on other machines; it gets created automatically during deployment. It works quite smoothly.
Is the CPU based on the ARM architecture?
Install with the root user, no need to configure password-free with -p.
It seems like the error is related to the architecture. Can you check if the architecture meets the requirements specified in the official documentation?
- Currently, TiUP Cluster supports deploying TiDB clusters on x86_64 (AMD64) and ARM architectures.
- For AMD64 architecture, it is recommended to use CentOS 7.3 or later versions of the Linux operating system.
- For ARM architecture, it is recommended to use CentOS 7.6 1810 version of the Linux operating system.
CPU architecture monitoring error, what machine are you using? What system? Check the official documentation to see if it is supported.
Try running it on the other two machines.
Have the hosts been changed?
