TiDB集群运维之扩缩容
2 --> 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 [root@bcm01 ~]# tiup cluster display tidbcluster Starting component `cluster`: /root/.tiup/components/cluster/v1.5.2/tiup-cluster display tidbcluster Cluster type: tidb Cluster name: tidbcluster Cluster version: v5.1.0 Deploy user: tidb SSH type: builtin Dashboard URL: http://192.168.120.201:2379/dashboard ID Role Host Ports OS/Arch Status Data Dir Deploy Dir -- ---- ---- ----- ------- ------ -------- ---------- 192.168.120.202:8300 cdc 192.168.120.202 8300 linux/x86_64 Up /u01/tidb/tidb-data/cdc-8300 /u01/tidb/tidb-deploy/cdc-8300 192.168.120.203:8300 cdc 192.168.120.203 8300 linux/x86_64 Up /u01/tidb/tidb-data/cdc-8300 /u01/tidb/tidb-deploy/cdc-8300 192.168.120.203:3000 grafana 192.168.120.203 3000 linux/x86_64 Up - /u01/tidb/tidb-deploy/grafana-3000 192.168.120.201:2379 pd 192.168.120.201 2379/2380 linux/x86_64 Up|L|UI /u01/tidb/tidb-data/pd-2379 /u01/tidb/tidb-deploy/pd-2379 192.168.120.203:2379 pd 192.168.120.203 2379/2380 linux/x86_64 Up /u01/tidb/tidb-data/pd-2379 /u01/tidb/tidb-deploy/pd-2379 192.168.120.202:9090 prometheus 192.168.120.202 9090 linux/x86_64 Up /u01/tidb/tidb-data/prometheus-9090 /u01/tidb/tidb-deploy/prometheus-9090 192.168.120.201:4000 tidb 192.168.120.201 4000/10080 linux/x86_64 Up - /u01/tidb/tidb-deploy/tidb-4000 192.168.120.202:4000 tidb 192.168.120.202 4000/10080 linux/x86_64 Up - /u01/tidb/tidb-deploy/tidb-4000 192.168.120.201:9000 tiflash 192.168.120.201 9000/8123/3930/20170/20292/8234 linux/x86_64 Up /u01/tidb/tidb-data/tiflash-9000 /u01/tidb/tidb-deploy/tiflash-9000 192.168.120.201:20160 tikv 192.168.120.201 20160/20180 linux/x86_64 Up /u01/tidb/tidb-data/tikv-20160 /u01/tidb/tidb-deploy/tikv-20160 192.168.120.202:20161 tikv 192.168.120.202 20161/20181 linux/x86_64 Up /u01/tidb/tidb-data/tikv-20161 /u01/tidb/tidb-deploy/tikv-20161 192.168.120.203:20162 tikv 192.168.120.203 20162/20182 linux/x86_64 Up /u01/tidb/tidb-data/tikv-20162 /u01/tidb/tidb-deploy/tikv-20162 2、创建scale-out.yaml文件 这里新加一个节点204，并在上面部署tidb、cdc以及pd服务，如下： [root@bcm01 ~]# vi scale-out.yaml tidb_servers: - host: 192.168.120.204 ssh_port: 22 port: 4000 status_port: 10080 deploy_dir: /u01/tidb/tidb-deploy/tidb-4000 log_dir: /u01/tidb/tidb-deploy/tidb-4000/log cdc_servers: - host: 192.168.120.204 pd_servers: - host: 192.168.120.204 ssh_port: 22 name: pd-192.168.120.204-2379 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/log 3、执行tiup命令进行扩容 [root@bcm01 ~]# tiup cluster scale-out tidbcluster scale-out.yaml Starting component `cluster`: /root/.tiup/components/cluster/v1.5.2/tiup-cluster scale-out tidbcluster scale-out.yaml Please confirm your topology: Cluster type: tidb Cluster name: tidbcluster Cluster version: v5.1.0 Role Host Ports OS/Arch Directories ---- ---- ----- ------- ----------- pd 192.168.120.204 2379/2380 linux/x86_64 /u01/tidb/tidb-deploy/pd-2379,/u01/tidb/tidb-data/pd-2379 tidb 192.168.120.204 4000/10080 linux/x86_64 /u01/tidb/tidb-deploy/tidb-4000 cdc 192.168.120.204 8300 linux/x86_64 /u01/tidb/tidb-deploy/cdc-8300,/u01/tidb/tidb-data/cdc-8300 Attention: 1.
