ubuntu18.04.2 Hadoop伪集群搭建

准备工作:

若没有下载vim请下载vim
1. 若出现 Could not get lock /var/lib/dpkg/lock 问题请参考：

https://jingyan.baidu.com/article/636f38bb861422d6b8461024.html

下载 openssh-server

1567428015806

查看ssh

如果显示sshd则说明已启动成功

查看主机

ifconfig -a

inet后面即为你的ip

Xshell连接

下载lrzsz, 然后就可以拖拉文件上传了

JDK配置

(1). 将jdk的tar包上传至soft目录, tar -zxvf 文件名将其解压, 并 mv 解压后的文件名 /usr/lib/jdk1.8

(2). sudo vim ~/.bashrc, 进入文件, 并在文件末尾添加jdk路径

1567428921685

(3). 配置好之后使其生效

~# source ~/.bashrc

再依次输入(蓝字为你要更新到的目录, 绿字为之前在/usr/lib下存储的jdk的组件)

sudo update-alternatives --install /usr/bin/java java /usr/lib/jdk1.8/bin/java 300

sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jdk1.8/bin/javac 300

sudo update-alternatives --install /usr/bin/jar jar /usr/lib/jdk1.8/bin/jar 300

sudo update-alternatives --install /usr/bin/javah javah /usr/lib/jdk1.8/bin/javah 300 

sudo update-alternatives --install /usr/bin/javap javap /usr/lib/jdk1.8/bin/javap 300

(4). 检查配置是否成功

执行java -version, 如显示版本

表示安装成功

Hadoop 单机版安装

(1). 去apache官网下载hadoop的tar.gz包(已经编译好了), 若下载src.tar.gz包则需要自己编译。将tar包上传并tar -zxvf 解压, 再将解压后的移至/usr/local目录下, mv hadoop-xxxx hadoop 重命名目录。

(2). vi .bashrc 进入配置文件并在文件末尾添加

#HADOOP VARIABLES
export HADOOP_HOME=/usr/lib/hadoop
export PATH=$PATH:$HADOOP_HOME/bin
export PATH=$PATH:$HADOOP_HOME/sbin
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

source .bashrc使环境变量生效

(3). 检查Hadoop路径配置

root@ronnie:/home/ronnie# hadoop version
Hadoop 3.1.2
Source code repository https://github.com/apache/hadoop.git -r 1019dde65bcf12e05ef48ac71e84550d589e5d9a
Compiled by sunilg on 2019-01-29T01:39Z
Compiled with protoc 2.5.0
From source with checksum 64b8bdd4ca6e77cce75a93eb09ab2a9
This command was run using /usr/local/hadoop/share/hadoop/common/hadoop-common-3.1.2.jar

(4) . 修改Hadoop配置

vim /usr/local/hadoop/etc/hadoop/hadoop-env.sh

将 export JAVA_HOME= 的注释解开并设置为jdk绝对路径:

export JAVA_HOME=/usr/lib/jdk1.8

(5). 进行WordCount测试

root@ronnie:~# cd /usr/local/hadoop/
root@ronnie:/usr/local/hadoop# cp README.txt input
root@ronnie:/usr/local/hadoop# ./bin/hadoop jar share/hadoop/mapreduce/sources/hadoop-mapreduce-examples-3.1.2-sources.jar org.apache.hadoop.examples.WordCount input output

输出结果:

修改/etc/sudoers文件

sudo vim /etc/sudoers

在root ALL=(ALL:ALL) ALL 此行下面添加

hadoop ALL=(ALL:ALL) ALL

修改/etc/hosts文件

sudo vim /etc/hosts

127.0.0.1       localhost.localdomain localhost
192.168.179.138     master
192.168.179.139     slave1
192.168.179.140     slave2

免密登录

在master, slave1 和slave2上执行ssh-keygen -t rsa -P ""生成RSA公钥私钥（记得enter）

1567561756532

在家目录(~)下vim .ssh/authorized_keys:

将三台虚拟机的公钥都存入该文件中:

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDleINRMFosnU6bMTHdNpm/OA4kER1AG3ZdqxmTkrQmikAKtEYp/4jvKTWIhziYiKJMbTw1crpUoHRFuThInvCjyMPQ9/BP9Sajd1+1XjOrviUofVQ9D33OjiAB3iOg61UQUJP2lsKPc58T0Igkf+vVKMHoJlfKDhJhHE4la+bcDRVMHY1hiEoNaeczazYvYXTzjsVDs21SCyqzYhe4h0aMg5071AJ/UDqt7YL+U0BGOWQyW1ww2QMsc6JG/pjrPbhlnE2zyggCvN9mk475gLi9fC2vHMcCeJVH5N+KUuiMPEGKiXi/EGcnv83Kq/NabH0zLIzIHbUQiZZhE4mpmpQf ronnie@master

依次测试三台虚拟机之间能否免密登录

（成功案例）

1567563911023

创建hadoop用户

为master和slave分别创建hadoop用户

sudo useradd -m hadoop -s /bin/bash
sudo passwd hadoop
sudo adduser hadoop sudo

更改hadoop目录权限

cd /usr/local
sudo chmod -R 777 hadoop/

更改hadoop目录拥有者

sudo chown -R hadoop:hadoop hadoop/

检查hadoop-env.sh文件

vim /usr/local/hadoop/etc/hadoop/hadoop-env.sh

1567565087133

若lib/ 后为jdk8则将其改为jdk1.8

同理修改mapred-env.sh文件以及yarn-env.sh

vim /usr/local/hadoop/etc/hadoop/mapred-env.sh
vim /usr/local/hadoop/etc/hadoop/yarn-env.sh

1567565556313

1567565726962

修改core-site.xml文件

vim /usr/local/hadoop/etc/hadoop/core-site.xml

此时使用ll命令会发现/usr/local/hadoop下生成了hdfs文件夹

ps: 若报错会显示配置文件的第几行几列有错, 修改后需要重启生效。

记得配置 workers文件:

vim /usr/local/hadoop/etc/hadoop/workers

localhost
master
slave1
slave2

开启集群

cd /usr/local/hadoop/
./sbin/start-all.sh

一个比较坑的地方是新版hadoop的端口为9870而不是50070......

1567600132319 1567600159390

启动成功, 今天就先到这了。
