【摘要】大数据系统又重又复杂，对于很多感兴趣、又想玩一把的同学来讲，门槛着实有点高，今天我选择了Apache Kudu这个项目，来手把手指导大家从源码开始构建一个本地的集群，然后进行简单的数据读写和集群管理。

< ">注意，以下操作只需要ctrl+c&ctrl+v即可:)

< ">< font-size: 18px;">2 准备工作

< ">在开始本文之前，建议在华为云购买一台云服务器，同时考虑到后续的顺利操作，云服务器需要有一些要求：

< ">CPU架构：x86计算

< ">规格：c6.2xlarge.2（提高编译速度）

< ">镜像：公共镜像，CentOS CentOS 8.0 64bit

< ">系统盘：高IO，100GB

< ">弹性公网：按流量计费（提高下载速度）

< ">< font-size: 18px;">3 操作系统

< ">安装软件包

[root ecs-kudu~]#yum install-y git autoconf automake libtool flex rsync gcc-c++.x86_64 cyrus-sasl-devel.x86_64 cyrus-sasl-plain.x86_64 openssl-devel.x86_64 java-1.8.0-openjdk-devel.x86_64

< ">< font-size: 18px;">4 编译源码

< ">clone代码：

[root ecs-kudu~]#git clone https://github.com/apache/kudu

< ">编译三方包

[root ecs-kudu~]#cd kudu/

[root ecs-kudu kudu]#./thirdparty/build-if-necessary.sh

< ">编译源码

[root ecs-kudu kudu]#mkdir-p build/release

[root ecs-kudu kudu]#cd build/release/
