A virtual machine with CentOS 7.9, x86_64, successfully deployed the test cluster, but encountered an error when starting the cluster: Error: failed to start tiflash: failed to start: xxx.xxx.xxx.xxx tiflash-9000.service, please check the instance’s log(/tidb-deploy/tiflash-9000/log) for more detail.: timed out waiting for port 9000 to be started after 2m0s

Check if port 9000 is in use.

There is no port 9000.

The virtual machine does not support the AVX2 instruction set. Refer to this: 关于dorisdb 本地搭建virtual_box虚拟机设置CPU支持AVX2指令集_virtualbox avx-CSDN博客

It seems that this version of the virtual machine is not supported. Try upgrading.

Installing VMware Workstation 17 is really great.

When deploying TiFlash on a hardware platform with the Linux AMD64 architecture, the CPU must support the AVX2 instruction set. Ensure that the command cat /proc/cpuinfo | grep avx2 has output. When deploying TiFlash on a hardware platform with the Linux ARM64 architecture, the CPU must support the ARMv8 architecture. Ensure that the command cat /proc/cpuinfo | grep 'crc32' | grep 'asimd' has output. By using vector extension instruction sets, TiFlash’s vectorized engine can provide better performance.
