My virtual machine address is 192.168.0.123. Changing the address to http://192.168.0.123:2379/dashboard also doesn’t open. I don’t know the reason.

TiFlash deployment failed, check if there are insufficient resources.

| username: ShawnYan | Original post link

Is there enough memory?

5
| username: 春风十里 | Original post link

How much memory does this need? I didn’t pay much attention, but I set the virtual machine memory to about 7-8GB.

| username: Billmay表妹 | Original post link

Check the official recommended configuration.

| username: Billmay表妹 | Original post link

The difference is significant~

You can download tiflash and manually execute LD_LIBRARY_PATH=./ ./tiflash version to see if it can print normal information (if it can print version information normally, it means the environment is compatible). The description here indicates that tiflash has some requirements for the CPU architecture instructions. You can refer to TiFlash 简介 | PingCAP 文档中心 for more details.

I’m just setting up a playground to take a look. Are there any minimum requirements for this?

| username: 春风十里 | Original post link

I deployed a virtual machine on my own desktop using VirtualBox. I’m not sure if there are any issues; I’ll check when I get home. According to the official documentation, there are specific requirements.

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

These are the requirements for a formal development or testing environment. I’m just learning and trying it out on my desktop. I saw in the lecture video that the instructor used a virtual machine on a Mac without any issues, so I posted to ask. I can’t quite understand the logs.

| username: Miniant256 | Original post link

If the course does not yet cover HTAP capabilities and TiFlash, you can temporarily skip deploying TiFlash:

tiup playground --tiflash 0

If resources are indeed insufficient but you still need to use TiFlash, you can try creating a TiDB Cloud Serverless Tier cluster. (There is a 5GB free quota, but note that the monitoring panel for the Serverless Tier is different from the one in your course, so I’m not sure if your course will cover monitoring.)

| username: 春风十里 | Original post link

There is no output, probably because the virtual machine created by my desktop does not support it.
