Usage

The tiup-cluster is distributed via tiup in a production environment. After installing the tiup, the user can use the tiup-cluster by typing command tiup cluster.

1. Deploy a cluster for production tiup-cluster deploy <cluster-name> <version> <topology.yaml> [flags]
2. Start a TiDB cluster tiup cluster start <cluster-name>
3. Stop a TiDB cluster tiup cluster stop <cluster-name>
4. Restart a TiDB cluster tiup cluster restart <cluster-name>
5. Scale in a TiDB cluster tiup cluster scale-in <cluster-name> --node <node-id-1> [node-id-2..N]
6. Scale out a TiDB cluster tiup cluster scale-out <cluster-name> <incr-topology.yaml>
7. Destroy a specified cluster tiup cluster destroy <cluster-name>
8. Upgrade a specified TiDB cluster tiup cluster upgrade <cluster-name> <version>
9. Run shell command on host in the tidb cluster tiup cluster exec <cluster-name> --command "ls"
10. Display information of a TiDB cluster tiup cluster display <cluster-name>
11. List all clusters tiup cluster list
12. Show audit log of cluster operation tiup cluster audit
13. Import an exist TiDB cluster from TiDB-Ansible tiup cluster import
14. Edit TiDB cluster config tiup cluster edit-config
15. Reload a TiDB cluster's config and restart if needed tiup cluster reload <cluster-name>

Contributing to TiUp

Contributions of code, tests, docs, and bug reports are welcome! To get started take a look at our open issues.

Environment

If you haven't cluster deploy environment, you can use the docker environment provided by tiup-cluster project.

1. Before initialize the environment, you should install Docker first.

2. After installing docker, you can bootstrap the development environment by following instructions

   cd docker
   sh up.sh --dev
   docker exec -it tiup-cluster-control bash
   

Quick start

1. Prepare a topology.

   global:
     user: tidb
   
   tidb_servers:
     - host: 172.19.0.101
   
   pd_servers:
     - host: 172.19.0.102
     - host: 172.19.0.104
     - host: 172.19.0.105
   
   tikv_servers:
     - host: 172.19.0.103
   
   grafana_servers:
     - host: 172.19.0.101
   
   monitoring_servers:
     - host: 172.19.0.102
   
   alertmanager_servers:
     - host: 172.19.0.103
   

2. Deploy a cluster

   tiup-cluster deploy test1 v3.0.10 topology.yaml -i ~/.ssh/id_rsa
   

The development doesn't depend on tiup, you can use tiup-cluster directly, which equal tiup cluster in the tiup mode.

Building

You can build tiup-cluster on any platform that supports Go.

Prerequisites:

• Go (minimum version: 1.13; installation instructions)
• make

To build tiup-cluster, run make build.

Local mirrors

The components depended by tiup-cluster will be downloaded from the tiup components repository, you can build a local mirror repository via the script https://github.com/pingcap-incubator/tiup/blob/master/localmirrors.sh. And set the environment variable via export TIUP_MIRRORS=/path/to/local/mirrors before sh up.sh --dev.
