4、编辑hosts 文件

(所有机器)

[root@hadoop101 /]# vim /etc/hosts
-- 注释掉内网 ip 对应的默认行  # 192.168.5.8   iZbp1ch91lmmx5lalz1i6iZ iZbp1ch91lmmx5lalz1i6iZ
192.168.5.8      hadoop101
192.168.5.9      hadoop102
192.168.5.10     hadoop103
192.168.5.11     hadoop104
192.168.5.12     hadoop105

5、关闭防火墙

(所有机器)

# 如果集群内的所有机器都是内网环境的，直接关闭防火墙是没啥问题的，如果是外网环境，就不能关闭防火墙了，而是开放端口,
# 以下命令需要在所有机子执行，临时和永久自己选择一种即可
# 查看防火墙状态
[root@hadoop101 /]# systemctl status firewalld.service
# 如果开启则关闭
[root@hadoop101 /]# systemctl stop firewalld.service
# 永久关闭 
[root@hadoop101 /]# systemctl disable firewalld.service

6、配置免密登录

(主节点hadoop101,hadoop102机上配置)

[root@hadoop101 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 回车

# 验证免密登录
[root@hadoop101 /]# ssh hadoop101
[root@hadoop101 /]# ssh hadoop102
[root@hadoop101 /]# ssh hadoop103
[root@hadoop101 /]# ssh hadoop104
[root@hadoop101 /]# ssh hadoop105

7、配置文件转发

(主节点机上hadoop101配置)

[root@hadoop101 ~]# cd /usr/local/bin/
[root@hadoop101 bin]# touch xsync
[root@hadoop101 bin]# vim xsync 

加入以下脚本

#!/bin/bash
#1 获取输入参数个数，如果没有参数，直接退出
pcount=$#
if [ $pcount -lt 1 ]
then
    echo Not Enough Arguement!
    exit;
fi

#2. 遍历集群所有机器
# 也可以采用：
# for host in hadoop{102..105};
for host in hadoop102 hadoop103 hadoop104  hadoop105
do
    echo ====================    $host    ====================
    #3. 遍历所有目录，挨个发送
    for file in $@
    do
        #4 判断文件是否存在
        if [ -e $file ]
        then
            #5. 获取父目录
            pdir=$(cd -P $(dirname $file); pwd)
            echo pdir=$pdir

            #6. 获取当前文件的名称
            fname=$(basename $file)
            echo fname=$fname

            #7. 通过ssh执行命令：在$host主机上递归创建文件夹（如果存在该文件夹）
            ssh $host "mkdir -p $pdir"

                        #8. 远程同步文件至$host主机的$USER用户的$pdir文件夹下
            rsync -av $pdir/$fname $USER@$host:$pdir
        else
            echo $file does not exists!
        fi
    done
done

将脚本文件xsync 授权 并测试 脚本

[root@hadoop101 bin]# chmod 777 xsync 
[root@hadoop101 bin]# xsync xsync
==================== hadoop102 ====================
pdir=/usr/local/bin
fname=xsync
sending incremental file list
xsync

sent 1,170 bytes  received 35 bytes  2,410.00 bytes/sec
total size is 1,080  speedup is 0.90
==================== hadoop103 ====================
pdir=/usr/local/bin
fname=xsync

xsync

sent 1,170 bytes  received 35 bytes  2,410.00 bytes/sec
total size is 1,080  speedup is 0.90
==================== hadoop104 ====================
pdir=/usr/local/bin
fname=xsync
sending incremental file list
xsync

sent 1,170 bytes  received 35 bytes  803.33 bytes/sec
total size is 1,080  speedup is 0.90

==================== hadoop105 ====================
pdir=/usr/local/bin
fname=xsync
sending incremental file list
xsync

sent 1,170 bytes  received 35 bytes  803.33 bytes/sec
total size is 1,080  speedup is 0.90

8、安装 JDK

（所有节点） 需要使用官网提供的jdk

（1）在hadoop 01的/opt目录下创建software文件夹

[root@hadoop101 opt]# mkdir software

（2）上传oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm并安装

[root@hadoop101 software]# rpm -ivh oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm

[root@hadoop101 software]# vim /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera

export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib

export PATH=$PATH:$JAVA_HOME/bin

[root@hadoop101 software]# source /etc/profile

[root@hadoop101 software]# java -version

java version “1.8.0_181”

（3）分发,并source

[root@hadoop101 software]# xsync /usr/java/jdk1.8.0_181-cloudera

[root@hadoop101 software]# xsync /etc/profile

[root@hadoop102 module]# source /etc/profile

[root@hadoop102 module]# java -version

[root@hadoop103 module]# source /etc/profile

[root@hadoop103 module]# java -version

[root@hadoop104 module]# source /etc/profile

[root@hadoop104 module]# java -version

[root@hadoop105 module]# source /etc/profile

[root@hadoop106 module]# java -version

9、MySQL中建库

由于使用 mysql 云数据 此处安装步骤省略

提前在云端数据库创建 好相应的库 以及授权

mysql> CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
mysql> CREATE USER scm@'%' IDENTIFIED BY 'scm';
mysql> GRANT ALL PRIVILEGES ON scm.* TO scm@'%';
mysql> FLUSH PRIVILEGES;

mysql> CREATE DATABASE hive DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
mysql> CREATE USER hive@'%' IDENTIFIED BY 'hive';
mysql> GRANT ALL PRIVILEGES ON hive.* TO hive@'%';
mysql> FLUSH PRIVILEGES;

mysql> CREATE DATABASE oozie DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
mysql> CREATE USER oozie@'%' IDENTIFIED BY 'oozie';
mysql> GRANT ALL PRIVILEGES ON oozie.* TO oozie@'%';
mysql> FLUSH PRIVILEGES;

mysql> CREATE DATABASE hue DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
mysql> CREATE USER hue@'%' IDENTIFIED BY 'hue';
mysql> GRANT ALL PRIVILEGES ON hue.* TO hue@'%';
mysql> FLUSH PRIVILEGES;

mysql 连接信息

ip： 192.168.10.15

端口：xxxx

用户名：xxxx

密码：xxxxx

10、CM安装部署

10.1、CM安装

（1）将mysql-connector-java-5.1.27-bin.jar拷贝到/usr/share/java 路径下，并重命名 mysql-connector-java.jar

[root@hadoop101 software]# mv mysql-connector-java-5.1.47.jar mysql-connector-java.jar
[root@hadoop101 software]# mkdir /usr/share/java
[root@hadoop101 software]# cp mysql-connector-java.jar /usr/share/java/

[root@hadoop101 software]# xsync /usr/share/java/

集群规划

节点	hadoop101	hadoop102	hadoop103	hadoop104	hadoop105
服务	cloudera-scm-servercloudera-scm-agent	cloudera-scm-agent	cloudera-scm-agent	cloudera-scm-agent	cloudera-scm-agent

10.2、创建cloudera-manager目录,存放cdh安装文件

[root@hadoop101 software]# mkdir /opt/cloudera-manager
[root@hadoop101 software]# tar -zxvf cm6.3.1-redhat7.tar.gz
[root@hadoop101 software]# cd cm6.3.1/RPMS/x86_64/
[root@hadoop101 x86_64]# cp cloudera-manager-agent-6.3.1-1466458.el7.x86_64.rpm /opt/cloudera-manager/

10.6、安装cloudera-manager-server

主节点hadoop101安装

[root@hadoop101 cloudera-manager]# rpm -ivh cloudera-manager-server-6.3.1-1466458.el7.x86_64.rpm 

10.7、上传CDH包到 /opt/cloudera/parcel-repo

[root@hadoop101 parcel-repo]# ll
total 2033432
-rw-r--r-- 1 root root 2082186246 May 21 11:10 CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel
-rw-r--r-- 1 root root         40 May 21 10:56 CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha1
-rw-r--r-- 1 root root      33887 May 21 10:56 manifest.json
[root@hadoop101 parcel-repo]# mv CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha1 CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha

10.8、修改server的db.properties

[root@hadoop101 parcel-repo]# vim /etc/cloudera-scm-server/db.properties 
# 此处填写对应的 mysql ip 端口 用户名 密码 数据库
com.cloudera.cmf.db.type=mysql
com.cloudera.cmf.db.host=192.168.10.15:10041
com.cloudera.cmf.db.name=scm
com.cloudera.cmf.db.user=scm
