tidb_servers:

  • host: 192.168.110.156

扩容后156tidb启动不起来：

访问 tikv 192.168.110.41:20161 检查156机器是否可以访问到41的20161端口 是否有防火墙拦截了
connect: connection refused

3

防火墙已经关闭了，telnet可以链接。

4

在41上 netstat -na |grep 192.168.110.156 看看有没有连过来的记录

5

网络连接问题、存储离线

6

看看有没有设置过ssh密钥

7

防火墙是否开启？

8

之前以为防火墙关闭了，又排查一边，发现没关闭，汗颜。。。

9

直接disable掉吧，省的以后麻烦
