TiDB集群运维之扩缩容
TiDB 集群可以在不中断线上服务的情况下进行扩容和缩容。本文使用 TiUP 扩容缩容集群中的 TiDB、TiKV、PD、TiCDC 或者 TiFlash 节点。1、扩容前集群状态
# tiup cluster display tidbcluster

这里新加一个节点204，并在上面部署tidb、cdc以及pd服务，如下：
# vi scale-out.yaml
tidb_servers:
- host: 192.168.120.204
ssh_port: 22
port: 4000
status_port: 10080

cdc_servers:
- host: 192.168.120.204
pd_servers:
- host: 192.168.120.204
ssh_port: 22

client_port: 2379
peer_port: 2380
deploy_dir: /u01/tidb/tidb-deploy/pd-2379
data_dir: /u01/tidb/tidb-data/pd-2379
log_dir: /u01/tidb/tidb-deploy/pd-2379/log3、执行tiup命令进行扩容
# tiup cluster scale-out tidbcluster scale-out.yaml

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.

Total nodes: 154、执行tiup命令进行缩容
缩容很简单，这里将204上的所有服务全部删除掉，如下：
# tiup cluster scale-in tidbcluster --node 192.168.120.204:8300 --node 192.168.120.204:2379 --node 192.168.120.204:4000
Starting component `cluster`: /root/.tiup/components/cluster/v1.5.2/tiup-cluster scale-in tidbcluster --node 192.168.120.204:8300 --node 192.168.120.204:2379 --node 192.168.120.204:4000
This operation will delete the 192.168.120.204:8300,192.168.120.204:2379,192.168.120.204:4000 nodes in `tidbcluster` and all their data.
Do you want to continue? :(default=N) y
Scale-in nodes...
