tidb4.0.4使用tiup扩容TiKV 节点

环境：centos7、tidb4.0.4、tiup-v1.0.8

添加两个tikv节点 172.21.210.37-38

思路：初始化两台服务器、配置ssh互通——>编辑配置文件——>执行扩容命令——>重启grafana

1、初始化服务器、配置ssh互通

1、时间同步
2、配置ssh
ssh-copy-id root@172.21.210.37
ssh-copy-id root@172.21.210.38

2、编辑配置文件

tiup cluster list                                     #查看当前的集群名称列表
tiup cluster edit-config <cluster-name>  #查看集群配置、拷贝对应的配置

vi scale-out.yaml
tikv_servers:
- host: 172.21.210.37
  ssh_port: 22
  port: 20160
  status_port: 20180
  deploy_dir: /data1/tidb-deploy/tikv-20160
  data_dir: /data1/tidb-data/tikv-20160
  arch: amd64
  os: linux
- host: 172.21.210.38
  ssh_port: 22
  port: 20160
  status_port: 20180
  deploy_dir: /data1/tidb-deploy/tikv-20160
  data_dir: /data1/tidb-data/tikv-20160
  arch: amd64
  os: linux

3、执行扩容命令

此处假设当前执行命令的用户和新增的机器打通了互信，如果不满足已打通互信的条件，需要通过 -p 来输入新机器的密码，或通过 -i 指定私钥文件。
tiup cluster scale-out <cluster-name> scale-out.yaml
预期输出 Scaled cluster <cluster-name> out successfully 信息，表示扩容操作成功

root@host-172-21-210-32 tidb_config]# tiup cluster scale-out tidb scale-out.yaml
Starting component `cluster`:  scale-out tidb scale-out.yaml
Please confirm your topology:
TiDB Cluster: tidb
TiDB Version: v4.0.4
Type  Host           Ports        OS/Arch       Directories
----  ----           -----        -------       -----------
tikv  172.21.210.37  20160/20180  linux/x86_64  /data1/tidb-deploy/tikv-20160,/data1/tidb-data/tikv-20160
tikv  172.21.210.38  20160/20180  linux/x86_64  /data1/tidb-deploy/tikv-20160,/data1/tidb-data/tikv-20160
Attention:
    1. If the topology is not what you expected, check your yaml file.
    2. Please confirm there is no port/directory conflicts in same host.
