說(shuō)明：在windos10上使用VmWare Workstation創(chuàng)建3節(jié)點(diǎn)Hadoop虛擬環(huán)境
創(chuàng)建虛擬機(jī)
下一步
設(shè)置虛擬機(jī)主機(jī)名和介質(zhì)存放路徑
設(shè)置20G磁盤(pán)大小
選擇“自定義硬件”
配置網(wǎng)絡(luò)模式為NAT模式
配置虛擬機(jī)啟動(dòng)鏡像
到這里，使用虛擬機(jī)克隆技術(shù)配置另外兩臺(tái)slave
同理克隆slave2, 步驟省略
此時(shí)windos網(wǎng)絡(luò)連接里面會(huì)出現(xiàn)兩張?zhí)摂M網(wǎng)卡
接下來(lái)就是給虛擬機(jī)配置IP網(wǎng)絡(luò)
虛擬機(jī)網(wǎng)卡IP要和NAT模式的IP是在同一個(gè)段，虛擬機(jī)才能通過(guò)windos筆記的VMnet8網(wǎng)卡與互聯(lián)網(wǎng)通信
接下來(lái)啟動(dòng)虛擬機(jī)配置操作系統(tǒng)IP網(wǎng)絡(luò)（具體配置過(guò)程省略）
1、環(huán)境規(guī)劃
Hadoop2.6.5+centos7.5
2、配置集群中主機(jī)域名訪問(wèn)解析
[root@master ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.11.10 master
192.168.11.11 slave1
192.168.11.12 slave2注：slaver1和slaver2也是同樣的配置
3.配置節(jié)點(diǎn)jdk環(huán)境

export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH使用/etc/profile文件立即生效
[root@master jdk1.8.0_172]# source /etc/profile驗(yàn)證jdk環(huán)境是否安裝成功

1>清空系統(tǒng)防火墻
iptables -F
iptables -X
iptables -Z2>臨時(shí)關(guān)閉內(nèi)核防火墻
setenforce 0
getenforce ##查看防火墻狀態(tài)3>永久性關(guān)閉內(nèi)核防火墻
vim /etc/sysconfig/selinux 把SELINUX狀態(tài)改為disabled
SELINUX=disabled5.配置集群節(jié)點(diǎn)ssh戶型
說(shuō)明：執(zhí)行以下操作，完成集群中的節(jié)點(diǎn)兩兩免密登陸
