tiup节点删除记录

 

从tidb4.0开始,不在使用传统的ansible-playbook来管理集群节点,换成了更加抽象的tiup组件,官方文档里面也推荐使用tiup组件的方式去部署安装管理tidb集群:

 

 

 

先检查当前集群状态,使用命令tiup cluster display hshclu:

tiup cluster display hshclu
Starting component `cluster`: /home/tidb/.tiup/components/cluster/v1.3.2/tiup-cluster display hshclu

删除tikv节点server,使用类似tiup cluster scale-in hshclu --node 172.1.2.104:20160的命令:

tiup cluster scale-in hshclu --node -y 172.1.2.104:20160

最后可以再次检查集群状态,还是使用之前的命令tiup cluster display hshclu:

大家是不是会有疑问,为什么会有一行Tombstone  呢?我重新执行了几遍tiup cluster display hshclu,这个Tombstone的记录还是顽强的存在,这个现象值得后续继续研究下。

<think>好的,我现在需要帮助用户了解TiUP Cluster的使用指南和配置教程。首先,我得回忆一下用户提供的引用内容,里面提到了TiUP Cluster是TiDB 4.0引入的运维工具,用于集群管理,包括部署、启动、关闭、扩缩容、升级和参数管理。用户还提到了一些引用内容,比如备份恢复、安装注意事项等。 用户的问题是关于TiUP Cluster的使用和配置,所以需要系统性地分步骤讲解。首先,我应该从安装开始,因为这是第一步。根据引用[4],安装TiDB时可能需要配置NTP服务器,所以安装TiUP是否需要这些步骤呢?不过引用[1]提到TiUP本身是运维工具,安装TiUP可能不需要修改NTP,但部署集群时需要。这点需要注意。 接下来,用户可能需要了解如何部署集群。引用[1]提到TiUP cluster组件可以部署集群,所以需要给出具体的部署命令,比如tiup cluster deploy。同时,引用[2]提到使用tag来持久化数据,这可能是在部署时需要注意的参数,需要包含在示例中。 然后是关于日常运维操作,如启动、停止、销毁集群,这些应该是基本操作,需要列出对应的命令。弹性扩缩容也是TiUP cluster的功能之一,需要说明如何添加节点或缩容节点。 升级集群部分,引用[1]提到升级功能,所以需要给出升级命令,比如tiup cluster upgrade。管理配置参数方面,可能需要使用edit-config命令,并重载配置。 备份和恢复方面,引用[3]提到BR工具的使用,但用户可能想知道如何结合TiUP进行备份恢复,所以需要提到使用tiup br命令,并给出示例,比如全量备份和恢复的命令。 配置方面,用户可能需要了解集群的拓扑文件结构,如何设置不同的组件参数,比如TiDB、TiKV、PD的配置项。引用[4]中的NTP配置可能在拓扑文件中设置,或者在部署时通过其他方式配置。 注意事项部分,需要提到备份时的数据安全,引用[3]中的定期备份建议,以及使用--force参数的风险。还有,测试环境部署后数据会被清理,使用--tag可以持久化,这点来自引用[2],需要强调。 最后,最佳实践和常见问题处理,比如版本兼容性、性能调优、监控集成,这些内容虽然引用中没有详细说明,但作为指南应该提及,并引导用户查阅官方文档或社区资源。 现在需要把这些内容组织成结构清晰的步骤,每个部分给出具体命令和示例,同时引用相关的内容作为支持。确保使用中文,并按照系统指令中的格式要求,行内公式用$...$,独立公式用$$...$$,但可能这里数学公式较少,主要关注命令和配置。同时生成相关问题,可能需要考虑用户在使用TiUP Cluster时可能遇到的疑问,比如安装问题、配置优化、备份策略等。</think>### TiUP Cluster 使用指南及配置教程 TiUP Cluster 是 TiDB 生态中的核心运维工具,支持集群的全生命周期管理。以下是详细的使用指南和配置说明: --- #### 一、安装 TiUP 及 Cluster 组件 1. **安装 TiUP** 执行以下命令一键安装 TiUP: ```bash curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh source ~/.bashrc # 使环境变量生效 ``` 验证安装:`tiup --version` 2. **安装 Cluster 组件** ```bash tiup cluster ``` 首次运行会自动下载组件。 --- #### 二、部署 TiDB 集群 1. **准备拓扑文件** 创建 `topology.yaml`,定义集群架构,例如: ```yaml global: user: "tidb" deploy_dir: "/data/tidb" pd_servers: - host: 10.0.1.1 - host: 10.0.1.2 tidb_servers: - host: 10.0.1.3 tikv_servers: - host: 10.0.1.4 - host: 10.0.1.5 ``` [^1] 2. **执行部署命令** ```bash tiup cluster deploy <cluster-name> v7.5.0 ./topology.yaml -y ``` 参数说明: - `<cluster-name>`: 自定义集群名称 - `v7.5.0`: TiDB 版本号 - `-y`: 自动确认操作 3. **启动集群** ```bash tiup cluster start <cluster-name> ``` 查看状态:`tiup cluster display <cluster-name>` --- #### 三、日常运维操作 1. **启停集群** - 启动:`tiup cluster start <cluster-name>` - 停止:`tiup cluster stop <cluster-name>` - 销毁:`tiup cluster destroy <cluster-name>`(谨慎操作)[^2] 2. **弹性扩缩容** - **扩容节点**:编辑拓扑文件后执行: ```bash tiup cluster scale-out <cluster-name> ./topology.yaml -y ``` - **缩容节点**: ```bash tiup cluster scale-in <cluster-name> --node 10.0.1.6:20160 -y ``` 3. **升级集群** ```bash tiup cluster upgrade <cluster-name> v7.5.1 -y ``` 4. **管理配置参数** - 修改配置: ```bash tiup cluster edit-config <cluster-name> ``` 编辑后保存,重启生效: ```bash tiup cluster reload <cluster-name> -R tidb,tikv ``` --- #### 四、备份与恢复 1. **使用 BR 工具备份** ```bash tiup br backup full --pd <PD_Endpoint> --storage "s3://backup-bucket/" --ratelimit 128 ``` 参数说明: - `--storage`: 备份存储路径(支持本地或 S3) - `--ratelimit`: 限速(单位:MB/s)[^3] 2. **恢复数据** ```bash tiup br restore full --pd <PD_Endpoint> --storage "s3://backup-bucket/" --force ``` ⚠️ `--force` 会覆盖现有数据,需谨慎使用[^3] --- #### 五、配置优化实践 1. **关键组件配置建议** - **TiKV**:调整 `raftstore.capacity` 控制存储容量。 - **PD**:设置 `replication.location-labels` 实现多机房容灾。 - **TiDB**:优化 `performance.max-procs` 限制 CPU 使用率。 2. **NTP 时间同步** 确保所有节点时间一致,编辑 `/etc/ntp.conf` 添加阿里云 NTP 服务器: ```conf server time1.aliyun.com server time2.aliyun.com ... ``` 重启服务:`systemctl restart ntpd`[^4] --- #### 六、注意事项 1. **数据持久化** 测试环境默认清理数据,若需保留,部署时添加 `--tag`: ```bash tiup --tag playground cluster deploy ... ```[^2] 2. **版本兼容性** 升级前需验证拓扑文件与目标版本的兼容性,建议先在测试环境操作[^3]。 ---
