## 模块 3: 检查已部署的 TiDB 集群状态 ### 步骤 1. 列出由 TiUP 管理的集群 ```bash tiup cluster list ``` ```output Name User Version Path PrivateKey ---- ---- ------- ---- ---------- tidb-test ec2-user v7.5.0 /home/ec2-user/.tiup/storage/cluster/clusters/tidb-test /home/ec2-user/.tiup/storage/cluster/clusters/tidb-test/ssh/id_rsa ``` ### 步骤 2. 检查已部署的 TiDB 集群的状态 ```bash tiup cluster display tidb-test ``` ```output Cluster type: tidb Cluster name: tidb-test Cluster version: v7.5.0 Deploy user: ec2-user SSH type: builtin Grafana URL: http://10.90.4.138:3000 ID Role Host Ports OS/Arch Status Data Dir Deploy Dir -- ---- ---- ----- ------- ------ -------- ---------- 10.90.4.138:9093 alertmanager 10.90.4.138 9093/9094 linux/x86_64 Down /tidb-data/alertmanager-9093 /tidb-deploy/alertmanager-9093 10.90.4.138:3000 grafana 10.90.4.138 3000 linux/x86_64 Down - /tidb-deploy/grafana-3000 10.90.2.138:2379 pd 10.90.2.138 2379/2380 linux/x86_64 Down /tidb-data/pd-2379 /tidb-deploy/pd-2379 10.90.2.231:2379 pd 10.90.2.231 2379/2380 linux/x86_64 Down /tidb-data/pd-2379 /tidb-deploy/pd-2379 10.90.2.90:2379 pd 10.90.2.90 2379/2380 linux/x86_64 Down /tidb-data/pd-2379 /tidb-deploy/pd-2379 10.90.4.138:9090 prometheus 10.90.4.138 9090/12020 linux/x86_64 Down /tidb-data/prometheus-9090 /tidb-deploy/prometheus-9090 10.90.1.169:4000 tidb 10.90.1.169 4000/10080 linux/x86_64 Down - /tidb-deploy/tidb-4000 10.90.1.56:4000 tidb 10.90.1.56 4000/10080 linux/x86_64 Down - /tidb-deploy/tidb-4000 10.90.4.126:9000 tiflash 10.90.4.126 9000/8123/3930/20170/20292/8234 linux/x86_64 N/A /tidb-data/tiflash-9000 /tidb-deploy/tiflash-9000 10.90.2.158:20160 tikv 10.90.2.158 20160/20180 linux/x86_64 N/A /tidb-data/tikv-20160 /tidb-deploy/tikv-20160 10.90.2.242:20160 tikv 10.90.2.242 20160/20180 linux/x86_64 N/A /tidb-data/tikv-20160 /tidb-deploy/tikv-20160 10.90.2.95:20160 tikv 10.90.2.95 20160/20180 linux/x86_64 N/A /tidb-data/tikv-20160 /tidb-deploy/tikv-20160 Total nodes: 12 ``` ### 步骤 3. 以普通启动方式启动 TiDB 集群 ```bash tiup cluster start tidb-test ``` ```output ...
