首先将需要安装的包上传到/opt/software目录下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2dka3l4eTIwMTM_size_16_color_FFFFFF_t_70][]

安装包的获取地址如下：

1、jdk：https://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html
    2、mysql：https://dev.mysql.com/downloads/mysql/5.7.html#downloads
    3、mysql jdbc jar包：http://central.maven.org/maven2/mysql/mysql-connector-java/5.1.47/mysql-connector-java-5.1.47.jar
    4、cm6.3.1：https://archive.cloudera.com/cm6/6.3.1/repo-as-tarball/cm6.3.1-redhat7.tar.gz
    5、Parcel：
    https://archive.cloudera.com/cdh6/6.3.1/parcels/CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel
    https://archive.cloudera.com/cdh6/6.3.1/parcels/CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel.sha1
    https://archive.cloudera.com/cdh6/6.3.1/parcels/manifest.json

# 二、环境搭建 #

小编使用了四台机器搭建CDH集群，其中一台作为master节点，另外三台作为slave节点。

## 1、设置主机名 ##

hostnamectl set-hostname cdh-master
    hostnamectl set-hostname cdh-slave01
    hostnamectl set-hostname cdh-slave02
    hostnamectl set-hostname cdh-slave03

## 2、配置主机映射 ##

在四个节点的/etc/hosts文件中添加如下内容：

192.168.0.192 cdh-master
    192.168.0.196 cdh-slave01
    192.168.0.197 cdh-slave02
    192.168.0.198 cdh-slave03

## 3、关闭集群防火墙 ##

四个节点同时执行：

systemctl stop firewalld && systemctl disable firewalld && iptables -F

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2dka3l4eTIwMTM_size_16_color_FFFFFF_t_70 1][]

## 4、关闭selinux ##

在四个节点的/etc/selinux/config文件中，将SELINUX设置为disabled：

SELINUX=disabled

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2dka3l4eTIwMTM_size_16_color_FFFFFF_t_70 2][]

## 5、配置免秘钥登录 ##

所有节点依次执行如下操作：

ssh-keygen
    ssh-copy-id cdh-master
    ssh-copy-id cdh-slave01
    ssh-copy-id cdh-slave02
    ssh-copy-id cdh-slave03

**注意：以上操作重启机器生效~**

reboot

## 6、设置集群时间同步 ##

（1）所有节点设置亚洲上海时区

timedatectl set-timezone Asia/Shanghai

（2）所有节点安装ntp服务

yum install -y ntp

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2dka3l4eTIwMTM_size_16_color_FFFFFF_t_70 3][]

（3）选取cdh-master为ntp的主节点，在主节点上修改配置文件/etc/ntp.conf：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2dka3l4eTIwMTM_size_16_color_FFFFFF_t_70 4][]

在该配置文件下方添加如下内容：

server  127.127.1.0     # local clock
    fudge   127.127.1.0 stratum 10

![20200709131913380.png][]

（4）在所有机器上执行如下命令：

systemctl start ntpd && systemctl enable ntpd

（5）修改cdh-master的时间与网络时间同步：

ntpdate -u  us.pool.ntp.org

（6）在cdh-master节点上修改本地硬件时钟时间：

hwclock --localtime   //查看本地硬件时钟时间 
    hwclock --localtime -w    //将系统时间写入本地硬件时钟时间

（7）cdh-master节点将本地硬件时钟时间与系统时间进行自动同步：

vi /etc/sysconfig/ntpdate
    SYNC_HWCLOCK=yes
    
    vi /etc/sysconfig/ntpd
    SYNC_HWCLOCK=yes

（8）slave节点执行crontab定时任务，定时向master节点同步时间：

*/20 * * * * /usr/sbin/ntpdate -u cdh-master

# 三、所有节点安装jdk #

以master节点为例：

[root@cdh-master ~]# mkdir /usr/java
    [root@cdh-master ~]# tar -zxf jdk-8u231-linux-x64.tar.gz -C /usr/java/
    [root@cdh-master ~]# chown -R root:root /usr/java/jdk1.8.0_231
    [root@cdh-master ~]# echo "export JAVA_HOME=/usr/java/jdk1.8.0_231" >> /etc/profile
    [root@cdh-master ~]# echo "export PATH=/usr/java/jdk1.8.0_231/bin:${PATH}" >> /etc/profile 
    [root@cdh-master ~]# source /etc/profile
    [root@cdh-master ~]# which java
    /usr/java/jdk1.8.0_231/bin/java
    [root@cdh-master ~]# java -version
    java version "1.8.0_231"
    Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
    Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

# 四、主节点部署jdbc驱动 #

mkdir -p /usr/share/java/
    cp mysql-connector-java-5.1.47.jar /usr/share/java/mysql-connector-java.jar

# 五、安装MySQL #

1、解压：

[root@cdh-master software]# tar -zxvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz -C /usr/local/

2、重命名：

[root@cdh-master software]# cd /usr/local/
    [root@cdh-master local]# mv mysql-5.7.11-linux-glibc2.5-x86_64 mysql

3、创建目录：

[root@cdh-master local]# mkdir mysql/arch mysql/data mysql/tmp

4、创建my.cnf：

[client]
    port            = 3306
    socket          = /usr/local/mysql/data/mysql.sock
    default-character-set=utf8mb4

    key_buffer_size = 256M
    sort_buffer_size = 256M
    read_buffer = 2M
    write_buffer = 2M

5、创建用户组及用户

[root@cdh-master local]# groupadd -g 101 dba
    [root@cdh-master local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
    [root@cdh-master local]# id mysqladmin
    uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)

设置mysqladmin的密码：

[root@cdh-master local]# passwd mysqladmin

如果用户已经存在，执行下面的命令：

[root@cdh-master local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

6、环境变量配置文件至mysqladmin用户的home目录中：

[root@cdh-master local]# cp /etc/skel/.* /usr/local/mysql

7、配置环境变量

[root@cdh-master local]# vi mysql/.bash_profile
    # .bash_profile
    # Get the aliases and functions
    
    if [ -f ~/.bashrc ]; then
            . ~/.bashrc
    fi
    
    # User specific environment and startup programs
    export MYSQL_BASE=/usr/local/mysql
    export PATH=${MYSQL_BASE}/bin:$PATH
    
    
    unset USERNAME
    
    #stty erase ^H
    set umask to 022
    umask 022
    PS1=`uname -n`":"'$USER'":"'$PWD'":>"; export PS1
    
    ## end

8、赋权

[root@cdh-master local]# chown  mysqladmin:dba /etc/my.cnf 
    [root@cdh-master local]# chmod  640 /etc/my.cnf  
    [root@cdh-master local]# chown -R mysqladmin:dba /usr/local/mysql
    [root@cdh-master local]# chmod -R 755 /usr/local/mysql

9、配置服务及开机自启：

[root@cdh-master local]# cd /usr/local/mysql
    #将服务文件拷贝到init.d下，并重命名为mysql
    [root@cdh-master mysql]# cp ./support-files/mysql.server /etc/rc.d/init.d/mysql
    #赋予可执行权限
    [root@cdh-master mysql]# chmod +x /etc/rc.d/init.d/mysql
    #删除服务
    [root@cdh-master mysql]# chkconfig --del mysql
    #添加服务
    [root@cdh-master mysql]# chkconfig --add mysql
    [root@cdh-master mysql]# chkconfig --level 345 mysql on

10、安装libaio及安装mysql的初始db：

[root@cdh-master mysql]# yum -y install libaio
    [root@cdh-master mysql]# su - mysqladmin

切换到mysqladmin用户下后，执行如下命令：

bin/mysqld \
    --defaults-file=/etc/my.cnf \
    --user=mysqladmin \
    --basedir=/usr/local/mysql/ \
    --datadir=/usr/local/mysql/data/ \
    --initialize

11、查看临时密码：

cat data/hostname.err |grep password 
    2017-07-22T02:15:29.439671Z 1 [Note] A temporary password is generated for root@localhost: tZgX7N-n;wO_

12、启动：

/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &

13、登录MySQL：

mysql -uroot -p'tZgX7N-n;wO_'

14、修改密码并赋权：

alter user root@localhost identified by 'p@ssw0rd';
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'p@ssw0rd';
    flush privileges;

15、退出，重启MySQL生效：

service mysql restart

16、再次登录MySQL，新建一些相关的数据库：

create database cmf DEFAULT CHARACTER SET utf8; 
    create database amon DEFAULT CHARACTER SET utf8; 
    grant all on cmf.* TO 'cmf'@'%' IDENTIFIED BY 'admin'; 
    grant all on amon.* TO 'amon'@'%' IDENTIFIED BY 'admin'; 
    flush privileges;
    create database hive DEFAULT CHARACTER SET utf8;
    grant all on hive.* TO 'hive'@'%' IDENTIFIED BY 'admin';
    flush privileges; 
    create database oozie DEFAULT CHARACTER SET utf8;
    grant all on oozie.* TO 'oozie'@'%' IDENTIFIED BY 'admin';
    flush privileges;
    create database hue DEFAULT CHARACTER SET utf8;
    grant all on hue.* TO 'hue'@'%' IDENTIFIED BY 'admin';
    flush privileges;

# 六、CDH部署 #

## 6.1 离线部署CM server及agent ##

### 6.1.1 创建目录解压软件 ###

所有节点执行如下操作：

mkdir /opt/cloudera-manager 
    tar -xzvf cm6.3.1-redhat7.tar.gz -C /opt/cloudera-manager/
