说好的Tidb快速上手，结果我安装的太慢了

Tidb安装报错:

[tidb@server01 ~]$ tiup playground v8.3.0 --db 2 --pd 3 --kv 3

请问这些报错是什么原因引起的，如何解决呢，谢谢CCTV，谢谢TiDB，谢谢有你。

字面的意思应该是 tiflash 连接不到 pd，是不是 pd ready 的时间慢于 tiflash ready 的时间？

3

:sweat_smile:不清楚，我是按文档第一次安装的，就遇到了这个错误。

4

我本地测也是 tiflash 部署有 error，临时方案加上。tiup playground 加上 --tiflash 0 吧

5

测试的话，不需要那么多节点，你就一台机器，直接tiup playground v8.3.0 --host 0.0.0.0就行，要那么多节点干啥，资源不够，启动都起不来

6

我猜你这服务器配置不够，资源不够，pd起来就挂了

7

一个机器跑这么多组件性能不够了吧，你的机器什么配置

8

所以最后是启动成功了么？display看看哪些组件没起来？

巧妇难为无米之炊，还是得有硬件。

笔记本是x1 64g内存，vmware给的4g 1cpu.

[root@server01 ~]# lscpu|grep -i cpu

看我这个安装吧，从最简单开始。

混布，然后pd根本都抢不到cpu执行。然后就连不上。就会报这个错。

12

你给他50G内存多核，试试。4g那么多节点组件吃内存肯定不够，这是分布式数据库。

13

分一半内存和cpu装

14

谢谢各位，确实是内存问题，我给1cpu 32g内存后就正常了，实际上给10g内存也差不多够。

在学习离线安装，参考下

16

看我这个文章吧，新鲜出炉的。

17

把节点数量设置为 1，playground 不用那么多节点

18

PD资源提高一点在看看

19

内存不够吧，多加点内存

我安装都是k8s一把梭，又快又稳
