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
shell
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:${KUDU_QUICKSTART_VERSION:-latest}
ports:
- "7051:7051"
- "8051:8051"
command: ["master"]
volumes:
- kudu-master-1:/var/lib/kudu
environment:
- KUDU_MASTERS=kudu-master-1:7051,kudu-master-2:7151,kudu-master-3:7251
- >
MASTER_ARGS=--fs_wal_dir=/var/lib/kudu/master
--rpc_bind_addresses=0.0.0.0:7051
--rpc_advertised_addresses=${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。
- ${KUDU_QUICKSTART_VERSION:-latest}:使用环境变量 KUDU_QUICKSTART_VERSION 指定版本,如果未设置,则默认使用 latest。
- ports:"7051:7051":将主机的 7051 端口映射到容器的 7051 端口,用于 Kudu Master 的 RPC 通信。"8051:8051":将主机的 8051 端口映射到容器的 8051 端口,用于 Kudu Master 的 Web 界面。
- command: ["master"]:指定容器启动时运行的命令,这里启动 Kudu Master 进程。
- volumes:kudu-master-1:/var/lib/kudu:将 Docker 卷 kudu-master-1 挂载到容器内的 /var/lib/kudu 目录,用于持久化存储数据。
- KUDU_MASTERS:定义了集群中所有 Master 节点的地址,格式为 hostname:port,以逗号分隔。
启动服务
shell
export KUDU_QUICKSTART_IP=$(ifconfig | grep "inet " | grep -Fv 127.0.0.1 | awk '{print $2}' | tail -1)
docker-compose up -d
访问服务
shell
http://localhost:8051/
这样我们的服务就顺利的启动了:
