章节内容

上节我们完成了如下的内容：

• Kudu 的基本介绍
• Kudu 的架构概述

安装准备

硬件准备

• 一台或者多台跑kudu-master。建议一个Master（无容错机制）、三个Master（允许一个节点出错）、五个Master（允许两个节点出错）
• 一台或者多台机器跑kudu-server。当需要使用副本，至少需要三个节点运行kudu-server服务。

操作系统

• Ubuntu云服务器（我的环境是三台小云服务器）
• 内核和文件系统支持 Hole Punching 选项。
• NTP 服务
• xfs or ext4 formatterd drivers

存储要求

• 尽量使用固态存储，显著提供kudu性能

环境说明

• 如果你使用的是CDH，需要ClouderaManager 5.4.3 及以上的版本。
• 三台云服务器，h121启动Master，h122和123启动TabletServer。

Dockerfile

https://github.com/apache/kudu/blob/master/docker/quickstart.yml

官方的配置文件为：

• 3个Master
• 4个TabletServer

内容解释

• version: “3”：指定使用 Docker Compose 文件的版本。版本 3 是当前常用的版本，支持多种高级功能，适用于 Docker 1.13.0 及更高版本。
• services：定义了多个服务，每个服务对应一个 Docker 容器。在本配置中，定义了多个 Kudu Master 和 Kudu Tablet Server（简称 TServer）。
• volumes：定义了持久化存储卷，用于存储各个服务的数据，确保即使容器重新创建或删除，数据仍然保留。

3 个 Kudu Master 节点：

• kudu-master-1
• kudu-master-2
• kudu-master-3

5 个 Kudu Tablet Server 节点：

• kudu-tserver-1
• kudu-tserver-2
• kudu-tserver-3
• kudu-tserver-4
• kudu-tserver-5

Master

每个 Master 节点的配置基本相同，只是端口和持久化卷不同。以下以 kudu-master-1 为例进行解释：

kudu-master-1:image: apache/kudu:${KUDU_QUICKSTART_VERSION:-latest}ports:- "7051:7051"- "8051:8051"command: ["master"]volumes:- kudu-master-1:/var/lib/kuduenvironment:- KUDU_MASTERS=kudu-master-1:7051,kudu-master-2:7151,kudu-master-3:7251- >MASTER_ARGS=--fs_wal_dir=/var/lib/kudu/master--rpc_bind_addresses=0.0.0.0:7051--rpc_advertised_addresses=${KUDU_QUICKSTART_IP:?Please set KUDU_QUICKSTART_IP environment variable}:7051--webserver_port=8051--webserver_advertised_addresses=${KUDU_QUICKSTART_IP}:8051--webserver_doc_root=/opt/kudu/www--stderrthreshold=0--use_hybrid_clock=false--unlock_unsafe_flags=true

• udu-master-1：服务名称，标识第一个 Kudu Master 节点。
• image: apache/kudu:${KUDU_QUICKSTART_VERSION:-latest}：指定使用的 Docker 镜像。apache/kudu 是官方 Kudu 镜像。
• ${KUDU_QUICKSTART_VERSION:-latest}：使用环境变量 KUDU_QUICKSTART_VERSION 指定版本，如果未设置，则默认使用 latest。
• ports：“7051:7051”：将主机的 7051 端口映射到容器的 7051 端口，用于 Kudu Master 的 RPC 通信。“8051:8051”：将主机的 8051 端口映射到容器的 8051 端口，用于 Kudu Master 的 Web 界面。
• command: [“master”]：指定容器启动时运行的命令，这里启动 Kudu Master 进程。
• volumes：kudu-master-1:/var/lib/kudu：将 Docker 卷 kudu-master-1 挂载到容器内的 /var/lib/kudu 目录，用于持久化存储数据。
• KUDU_MASTERS：定义了集群中所有 Master 节点的地址，格式为 hostname:port，以逗号分隔。

启动服务

export KUDU_QUICKSTART_IP=$(ifconfig | grep "inet " | grep -Fv 127.0.0.1 | awk '{print $2}' | tail -1)
docker-compose up -d

访问服务

http://localhost:8051/

这样我们的服务就顺利的启动了：
