大数据平台CDH5.14.2 的安装配置标签（空格分隔）： 大数据平台构建
- 一：系统环境初始化
- 二：安装CDH5.14.2 平台
- 三：分配主机与分配角色
系统： CentOS7.5X64

-----
本次 安装只配置其中三台机器： 172.17.100.11到 172.17.100.13 
yum install -y firewall* iptable*
(1) 关闭firewalld
systemctl stop firewalld.service
systemctl disable firewalld.service
firewall-cmd --state
(2) 关闭iptables
iptables -F
systemctl stop iptables.service
service iptables save
systemctl disable iptables.service
(3) 禁用 selinux
sed -i ‘/SELINUX/s/enforcing/disabled/‘ /etc/selinux/config
setenforce 0
getenforce 0
sestatus
重启机器
reboot
做root用户无密钥认证
ssh-keygen ---一直敲回车到最后
cat id_rsa.pub >> authorized_keys
将所有的公钥导入authorized_keys 分发到 所有的 机器的.ssh/ 下面
然后测试
1): 卸载原来的jdk
rpm -e java-1.7.0-openjdk-1.7.0.141-2.6.10.5.el7.x86_64 java-1.6.0-openjdk-devel-1.6.0.41-1.13.13.1.el7_3.x86_64 java-1.8.0-openjdk-headless-1.8.0.131-11.b12.el7.x86_64 java-1.7.0-openjdk-headless-1.7.0.141-2.6.10.5.el7.x86_64 copy-jdk-configs-2.2-3.el7.noarch java-1.8.0-openjdk-1.8.0.131-11.b12.el7.x86_64 java-1.7.0-openjdk-devel-1.7.0.141-2.6.10.5.el7.x86_64 java-1.8.0-openjdk-devel-1.8.0.131-11.b12.el7.x86_64 java-1.6.0-openjdk-1.6.0.41-1.13.13.1.el7_3.x86_64 tzdata-java-2017b-1.el7.noarch python-javapackages-3.4.1-11.el7.noarch javapackages-tools-3.4.1-11.el7.noarch --nodeps
2) 安装 jdk:
rpm -ivh oracle-j2sdk1.7-1.7.0+update67-1.x86_64.rpm
vim /etc/profile
最后增加：
### JDK ####

export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
