本文搭建了一个由四节点(master、slave1、slave2、slave3)构成的Hadoop完全分布式集群
虚拟机安装:VMWare
ip分配:
master内网IP:192.168.248.136
slave01内网IP:192.168.248.137
slave02内网IP:192.168.248.138
slave03内网IP:192.168.248.139
ssh免密登录
##创建hadoop用户
[root@localhost ~]# useradd -m hadoop
[root@localhost ~]# passwd hadoop
Changing password for user hadoop.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
Sorry, passwords do not match.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password: ##123456
passwd: all authentication tokens updated successfully.
## 为hadoop添加sudo权限
[root@localhost ~]# vim /etc/sudoers
#在该行root ALL=(ALL) ALL下添加hadoop ALL=(ALL) ALL保存后退出,并切换回hadoop用户
[root@localhost ~]# su hadoop
[hadoop@localhost root]$
## 注意事项:四个节点的用户名必须相同,不然以后会对后面ssh及hadoop集群搭建产生巨大影响
##为了不直接使用IP,可以通过设置hosts文件达到ssh slave1这样的的效果(四个节点设置相同)
192.168.248.136 master
192.168.248.137 slave01
192.168.248.138 slave02
192.168.248.139 slave03
#注意事项:不要在127.0.0.1后面添加主机名,如果加了master,会造成后面hadoop的一个很坑的问题,在slave节点应该解析出masterIP的时候解析出127.0.0.1,造成hadoop搭建完全正确,但是系统显示可用节点一直为0。
#修改hostname
#centos7默认的hostname是localhost,为了方便将每个节点hostname分别修改为master、slave01、slave02、slave03(以下以master节点为例)
[hadoop@localhost root]$ sudo hostnamectl set-hostname master
[hadoop@localhost root]$ hostname
master
#ssh设置
#设置master节点和两个slave节点之间的双向ssh免密通信
# 1. 首先生成master的rsa密钥
[hadoop@localhost root]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/hadoop/.ssh/id_rsa):
Created directory '/home/hadoop/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/hadoop/.ssh/id_rsa.
Your public key has been saved in /home/hadoop/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:fX0pBEdHV++J+urYGSrz4MSdblBt8bXKqGyMPXDuoMU hadoop@master

# 2. 将生成的rsa追加写入授权文件
[hadoop@localhost root]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
# 3. 给授权文件权限
[hadoop@localhost root]$ chmod 600 ~/.ssh/authorized_keys
# 4. 进行本机ssh测试:$ssh maste r正常免密登陆后所有的ssh第一次都需要密码,此后都不需要密码
[hadoop@localhost root]$ ssh master

[hadoop@master ~]$
# 5. 将master上的authorized_keys传到slave01
[hadoop@localhost root]$ sudo scp ~/.ssh/id_rsa.pub hadoop@slave01:~/
hadoop@slave01's password:

# 6. 登陆到slave1操作:$ssh slave1输入密码登陆
[hadoop@localhost root]$ cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
# 7. 修改authorized_keys权限
[hadoop@localhost root]$ chmod 600 ~/.ssh/authorized_keys
# 8. 在master 进行免密登录测试
[hadoop@localhost root]$ ssh slave01

# 9. 同理对slave02、slave03操作
jdk的安装
[hadoop@localhost app]$ ls
jdk1.8.0_211 jdk-8u211-linux-x64.tar.gz
[hadoop@localhost app]$ vim ~/.bashrc
export JAVA_HOME=/usr/local/app/jdk1.8.0_211
export PATH=$PATH:$JAVA_HOME/bin
# 使环境变量生效:
[hadoop@localhost app]$ source ~/.bashrc
Hadoop的安装
##1. 目的:获得正确配置的完全分布式Hadoop集群(以下操作均在master主机下操作)
# 安装前所有节点都需要需要关闭防火墙和selinux
[hadoop@localhost app]$ sudo systemctl stop firewalld.service
[sudo] password for hadoop:
[hadoop@localhost app]$
[hadoop@localhost app]$ sudo systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
##2. 下载并上传hadoop
[hadoop@localhost app]$ ll
total 548284
drwxr-xr-x. 9 501 dialout 149 Nov 13 2018 hadoop-2.9.2
-rw-r--r--. 1 root root 366447449 Jun 8 20:49 hadoop-2.9.2.tar.gz
drwxr-xr-x. 7 10 143 245 Apr 2 11:51 jdk1.8.0_211
-rw-r--r--. 1 root root 194990602 Jun 8 01:12 jdk-8u211-linux-x64.tar.gz
## 注意事项:hadoop有32位和64位之分,官网默认二进制安装文件是32位的,但是本文操作系统是64位,会在后面hadoop集群使用中产生一个warning但是不影响正常操作。

配置环境变量
配置环境变量,修改~/.bashrc文件,添加行(每个节点都需要此步操作,以master节点为例):
#hadoop environment vars

export HADOOP_MAPRED_HOME=$HADOOP_HOME
