Hadoop
一、环境搭建VMware ,CentOS7,Ubuntu
1、VMware Workstation 15 Pro安装图解教程
详细见：https://www.shuzhiduo.com/A/Gkz1PGeQdR/
2、VMware Workstation 15 Pro安装带图形化界面的CentOS7
详细见：https://www.shuzhiduo.com/A/qVde08Gg5P/
3、VMware Workstation 15 Pro中安装ubuntu1804
详细见：https://www.shuzhiduo.com/A/MAzAPGWnd9/
注释：强烈安利复制粘贴、适应屏幕（安装VMware Tools）
二.创建普通用户(本人一开始用了，后面全部直接用的root)
1.在当前用户下面创建hadoop用户
[root@localhost ~]# useradd -m hadoop -s /bin/bash
[root@localhost ~]# passwd hadoop
2.如果不是root用户
[用户@localhost ~]# sudo useradd -m hadoop -s /bin/bash
[用户@localhost ~]# sudo passwd hadoop
3.为hadoop用户添加管理员权限
[root@localhost ~]# adduser hadoop sudo
三.安装jdk
[hadoop@localhost ~]$ su
密码：
[root@localhost hadoop]# ls

[root@hadoop001 network-scripts]#
六、主机名设置
1.编辑网络配置文件
[root@hadoop001 network-scripts]# vim /etc/sysconfig/network
# Created by anaconda
NETWORKING=yes
HOSTNAME=hadoop001
2.永久设置主机名
[root@hadoop001 network-scripts]# hostnamectl set-hostname hadoop001
3.重启
[root@hadoop001 network-scripts]# hostnamectl set-hostname hadoop001
4.查看主机名是否有效
[root@hadoop001 ~]# hostname
hadoop001
另外几台分别同样操作设置为hadoop002,hadoop003
七、hosts文件配置
配置IP和hostname的映射关系
[root@hadoop001 ~]# vim /etc/hosts
#增加
192.168.1.100 hadoop001
192.168.1.101 hadoop002
192.168.1.102 hadoop003
其他台配置一样
八、安装本机ssh免密登陆
1.关闭防火墙(永久)和SELinux（root权限）
[root@hadoop001 ~]# vim /etc/selinux/config
修改 /etc/selinux/config 文件中的 SELINUX=enforcing 修改为 SELINUX=disabled ，然后重启。
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
#SELINUX=enforcing
SELINUX=disabled #修改为disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
~
~
~
~
"/etc/selinux/config" 15L, 565C
2.ssh免密登录
[root@hadoop001 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:F0VeLRWK+eOPDIccQgNhUfKWbo1tYrp28j9NHzw3HYk root@hadoop001
The key's randomart image is:
+---[RSA 2048]----+
| *+. .o .+o|
| . + .oo.o .|
| *.o.....|
| + =..E o |
| SB.= o. o|
| +.= +..=o|
| . +oo. =|
| o.. .+.o. |
| ..+....o . |
+----[SHA256]-----+
[root@hadoop001 ~]#
3.向本机复制公钥
[root@hadoop001 ~]# cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
4.登录hadoop001验证(第一次输入yes回车进入就表示免密码登录配置成功)
[root@hadoop001 ~]# ssh hadoop001
The authenticity of host 'hadoop001 (192.168.1.100)' can't be established.
ECDSA key fingerprint is SHA256:RcMX0Yg6dBCZlIAM3cS0Rh/fSwNjJSCr2TNb3GPup4I.
ECDSA key fingerprint is MD5:d5:1a:ac:1f:33:c0:30:3f:95:68:41:a5:33:17:20:4f.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'hadoop001,192.168.1.100' (ECDSA) to the list of known hosts.
Last login: Sun Mar 28 14:40:59 2021
[root@hadoop001 ~]#
5.把公钥复制到另外两台虚拟机(途中输入密码)
[root@hadoop001 ~]# ssh-copy-id -i hadoop002
[root@hadoop001 ~]# ssh-copy-id -i hadoop003
6.验证在hadoop001上面使用ssh命令确认集群免密码登录是否成功，可以免密码登录说明是没有问题
[root@hadoop001 ~]# ssh hadoop002
Last login: Sun Mar 28 14:45:37 2021
[root@hadoop002 ~]# exit
登出
Connection to hadoop002 closed.
[root@hadoop001 ~]# ssh hadoop003
Last login: Sun Mar 28 14:48:32 2021
[root@hadoop003 ~]# exit
登出

或者(差不多)
2.配置sshd（root权限）
[hadoop@localhost root]$ sudo vi /etc/ssh/sshd_config
vim进去修改配置
43 PubkeyAuthentication yes
47 AuthorizedKeysFile .ssh/authorized_keys
添加部分
140 RSAAuthentication yes
重启 sshd 服务，使用命令：systemctl restart sshd.service 。
[hadoop@localhost root]$ systemctl restart sshd.service
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to manage system services or units.
Authenticating as: hadoop
Password:
==== AUTHENTICATION COMPLETE ===
[hadoop@localhost root]$
3.生成秘钥（普通用户权限）
从 root 用户切换到hadoop 用户，可使用命令：su hadoop。然后， 执行命令 ssh-keygen -t rsa 来生成秘钥。无需指定口令密码，遇到询问直接回车，命令执行完毕后会在 hadoop 用户的家目录中（/home/hadoop/.ssh）生成两个文件：
id_rsa 私钥
id_rsa.pub 公钥
[hadoop@localhost root]$ su hadoop
密码：
[hadoop@localhost root]$ ssh-keygen -trsa
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:
SHA256:3E8juUADf2abvIQypfJSeaecamsXbe7ddtzFXAkFBZw hadoop@localhost.localdomain
The key's randomart image is:

httpfs-env.sh workers
httpfs-log4j.properties yarn-env.cmd
httpfs-site.xml yarn-env.sh
kms-acls.xml yarnservice-log4j.properties
kms-env.sh yarn-site.xml
[root@hadoop001 hadoop]#
2.配置core-site.xml文件 ，添加如下配置
[root@hadoop001 hadoop]# vim core-site.xml
<configuration>
<property>
<name>fs.defaultFS</name>
<!-- 这里填的是你自己的ip，端口默认-->
<!-- 这样貌似也可以<value>hdfs://192.168.187.128:9000</value> -->
<value>hdfs://hadoop001:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<!-- 这里填的是你自定义的hadoop工作的目录，端口默认-->
<value>/usr/hadoop330/hadoop-3.3.0/tmp</value>
</property>
</configuration>
3.配置hdfs-site.xml文件,把hdfs中文件副本的数量设置为2
[root@hadoop001 hadoop]# vim hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>2</value>
</property>
<property>
<name>dfs.namenode.secondary.http-address</name>
<value>hadoop001:50090</value>
</property>
</configuration>
4.配置mapred-site.xml文件,设置mapreduce使用资源调度的框架

[root@hadoop001 sbin]# vim stop-yarn.sh
YARN_RESOURCEMANAGER_USER=root
HADOOP_SECURE_DN_USER=yarn
YARN_NODEMANAGER_USER=root
10.格式化namenode
[root@hadoop001 sbin]# cd /usr/hadoop330/hadoop-3.3.0/
[root@hadoop001 hadoop-3.3.0]# ls
bin include LICENSE-binary NOTICE-binary sbin
core-site.xml lib licenses-binary NOTICE.txt share
etc libexec LICENSE.txt README.txt
[root@hadoop001 hadoop-3.3.0]# bin/hdfs namenode -format
#或者直接
[root@hadoop001 ~]# cd $HADOOP_HOME
[root@hadoop001 hadoop-3.3.0]# bin/hdfs namenode -format
