本文详细介绍了一种Java集群部署方案，包括目录创建、JDK安装、环境变量配置及分发等关键步骤，确保集群环境中Java的一致性和稳定性。

【云星数据—大数据部集群署系列002】：Java部署方案

1.创建目录

ssh bigdata002 'mkdir -p /cloudstar/software/'
ssh bigdata003 'mkdir -p /cloudstar/software/'
ssh bigdata004 'mkdir -p /cloudstar/software/'
ssh bigdata005 'mkdir -p /cloudstar/software/'
ssh bigdata006 'mkdir -p /cloudstar/software/'
ssh bigdata007 'mkdir -p /cloudstar/software/'
ssh bigdata008 'mkdir -p /cloudstar/software/'
ssh bigdata009 'mkdir -p /cloudstar/software/'
ssh bigdata010 'mkdir -p /cloudstar/software/'

2.安装jdk

1.配置环境变量
    vim　~/.bashrc
    配置如下内容：
    export JAVA_HOME=/cloudstar/software/jdk1.8.0_151
    export PATH=$PATH:$JAVA_HOME/bin
2.测试环境变量
    测试命令
    java -veriosn
    命令回显
    java version "1.8.0_151"
    Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
    Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
3.分发环境变量
    scp ~/.bashrc bigdata002:~/.bashrc
    scp ~/.bashrc bigdata003:~/.bashrc
    scp ~/.bashrc bigdata004:~/.bashrc
    scp ~/.bashrc bigdata005:~/.bashrc
    scp ~/.bashrc bigdata006:~/.bashrc
    scp ~/.bashrc bigdata007:~/.bashrc
    scp ~/.bashrc bigdata008:~/.bashrc
    scp ~/.bashrc bigdata009:~/.bashrc
    scp ~/.bashrc bigdata010:~/.bashrc

4.分发java
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata002:/cloudstar/software/
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata003:/cloudstar/software/
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata004:/cloudstar/software/
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata005:/cloudstar/software/
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata006:/cloudstar/software/
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata007:/cloudstar/software/
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata008:/cloudstar/software/
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata009:/cloudstar/software/
    scp -r /cloudstar/software/jdk1.8.0_151 bigdata010:/cloudstar/software/
