另外需要下载 allkeys.asc

https://archive.cloudera.com/cm6/6.3.1/allkeys.asc

2.2、下载 CDH 安装包

下载地址：CDH 安装包下载

https://archive.cloudera.com/cdh6/6.3.2/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel

https://archive.cloudera.com/cdh6/6.3.2/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha1

https://archive.cloudera.com/cdh6/6.3.2/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha256

https://archive.cloudera.com/cdh6/6.3.2/parcels/manifest.json

2.3、下载 MySQL JDBC Driver

注意：默认位置 /usr/share/java/ ，默认驱动名 mysql-connector-java.jar

# 创建文件夹
mkdir -p /usr/share/java/

# 进入 MySQL 驱动文件目录
cd /usr/share/java/

# 下载 MySQL 驱动
wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz

# -bash: wget: 未找到命令
yum -y install wget

# 解压压缩包
tar zxvf mysql-connector-java-5.1.46.tar.gz

# 复制并且重命名
cp /usr/share/java/mysql-connector-java-5.1.46/mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar

2、安装前环境配置

2.1、配置静态 IP 地址

# 查看当前 IP 信息
ip addr
 
# 编辑文件
vi /etc/sysconfig/network-scripts/ifcfg-enp2s0
 
# 将动态获取 IP 改为 静态获取
BOOTPROTO="dhcp" 改为 BOOTPROTO="static"

# 复制以下内容
#IP地址
IPADDR0=10.0.0.1
#子网掩码
PREFIX0=24
#网关地址
GATEWAY0=10.0.0.254
DNS1=8.8.8.8

# 重启网络服务
systemctl restart network

2.2、修改主机名称

# 所有机器都需要修改主机名称
hostnamectl set-hostname woniu

2.3、配置主机名跟 IP 地址映射

# 所有机器都需编辑 hosts 文件
vi /etc/hosts
 
# 添加如下内容
10.0.0.1 woniu
10.0.0.2 woniu1
10.0.0.3 woniu2

2.4、关闭防火墙

# 所有机器都需要关闭防火墙
systemctl stop firewalld.service
 
# 禁止开机启动
systemctl disable firewalld.service

2.5、设置 selinux

# 临时关闭 selinux
setenforce 0

# 永久关闭 selinux
sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

2.6、设置 SSH 免密码登录

# 生成秘钥，无需指定口令密码，直接回车
ssh-keygen -t rsa

# 将公钥导入到认证文件
cat  ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

# 认证文件合并，输入 yes 回车再输入服务器密码
ssh-copy-id -i ~/.ssh/id_rsa.pub  root@woniu1
ssh-copy-id -i ~/.ssh/id_rsa.pub  root@woniu2

2.7、部署 NTP 服务器进行时间同步

参考文章：CentOS7 部署 NTP 服务器进行时间同步

# 安装 ntp
yum install -y ntp

# 启动ntp
systemctl start ntpd
 
# 开机自动启动
systemctl enable ntpd

# 查看ntp状态
systemctl status ntpd

服务端配置

# 编辑文件
vi /etc/ntp.conf

# 日志配置
logfile /var/log/ntpd.log
 
# 允许网段内客户端连接此服务器同步时间，但是拒绝让他们修改服务器上的时间
restrict 10.0.0.0 mask 10.0.0.255 nomodify notrap
 
# 配置时间服务器（阿里云）
https://www.ntppool.org/zone/asia
 
server ntp1.aliyun.com
server ntp2.aliyun.com
server ntp3.aliyun.com
 
# 在 /ntp.conf 中定义的 server 都不可用时，将使用 local 时间作为 ntp 服务提供给 ntp 客户端。
# 建议配置，否则 ntp 服务器无法与公网 ntp 服务器同步时，其客户端也会无法同步
server 127.0.0.1
fudge 127.0.0.1 stratum 10

客户端配置

# 编辑文件
vi /etc/ntp.conf
 
# 日志配置
logfile /var/log/ntpd.log
 
# 配置时间服务器
server 10.0.0.1

2.8、安装 JDK8

下载地址：https://www.oracle.com/technetwork/java/javase/archive-139210.html

# 创建文件夹
mkdir -p /usr/java/

# 上传 JDK8 压缩文件

# 解压
tar -zxvf jdk-8u231-linux-x64.tar.gz

# 配置当前用户环境变量
vi ~/.bash_profile
 
# 在文件中添加如下命令，记得切换自己文件路径
export JAVA_HOME=/usr/java/jdk1.8.0_231
export PATH=$JAVA_HOME/bin:$PATH
 
# 立即生效
source ~/.bash_profile

3、Cloudera Manager 安装

3.1、配置本地 Cloudera Manager 仓库

# 创建本地 CM 仓库文件夹
mkdir -p /var/www/html/cloudera-repos/cm6/

# 上传下载好的 CM 安装包放入 /var/www/html/cloudera-repos/cm6/ 目录

# 安装 httpd 和 createrepo
yum -y install httpd createrepo

# 启动 httpd 服务并设置为开机自启动
systemctl start httpd && systemctl enable httpd

# 生成 RPM，注意最后必须有 .
cd /var/www/html/cloudera-repos/cm6/ && createrepo .

# 通过浏览器访问了：默认端口 80
http://woniu/cloudera-repos/cm6/

3.2、配置本地 CDH 仓库

# 创建本地 CDH 仓库文件夹
mkdir -p /var/www/html/cloudera-repos/cdh6/

# 上传下载好的 CDH 安装包放入 /var/www/html/cloudera-repos/cdh6/ 目录

# 生成 RPM，注意最后必须有 .
cd /var/www/html/cloudera-repos/cdh6/ && createrepo .

# 通过浏览器访问了：默认端口80
http://woniu/cloudera-repos/cdh6/

3.3、构建 yum 源

# 所有机器都需要配置
vi /etc/yum.repos.d/cloudera-repo.repo

# 拷贝如下内容
[cloudera-repo]
name=cloudera-repo
baseurl=http://woniu/cloudera-repos/cm6/
enabled=1
gpgcheck=0

# 清理
yum clean all
yum makecache

systemctl start mysqld

# 开机自启动
systemctl enable mysqld

2、初始化数据库

# 初始化数据库
/usr/bin/mysql_secure_installation

3、备份数据库配置文件

cp /etc/my.cnf{,.bak}

4、官网推荐配置

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
transaction-isolation = READ-COMMITTED
# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
symbolic-links = 0

key_buffer_size = 32M
max_allowed_packet = 32M
thread_stack = 256K
thread_cache_size = 64
query_cache_limit = 8M
query_cache_size = 64M
query_cache_type = 1

max_connections = 550
#expire_logs_days = 10
#max_binlog_size = 100M

#log_bin should be on a disk with enough free space.
#Replace '/var/lib/mysql/mysql_binary_log' with an appropriate path for your
#system and chown the specified folder to the mysql user.
log_bin=/var/lib/mysql/mysql_binary_log

#In later versions of MySQL, if you enable the binary log and do not set
#a server_id, MySQL will not start. The server_id must be unique within
#the replicating group.
server_id=1

binlog_format = mixed

read_buffer_size = 2M
read_rnd_buffer_size = 16M
sort_buffer_size = 8M
join_buffer_size = 8M

# InnoDB settings
innodb_file_per_table = 1
innodb_flush_log_at_trx_commit  = 2
innodb_log_buffer_size = 64M
innodb_buffer_pool_size = 4G
innodb_thread_concurrency = 8
innodb_flush_method = O_DIRECT
innodb_log_file_size = 512M

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

sql_mode=STRICT_ALL_TABLES

6、创建数据库

drop database oozie;
flush privileges;

3.5、安装 CM Server 和 Agent

主节点

yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server

所有从节点

yum install cloudera-manager-daemons cloudera-manager-agent

3.6、建立CM的数据库

参考文档：官网创建 CM 数据库教程

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm

3.7、启动 CM Server

# 启动服务
systemctl start cloudera-scm-server

# 查看服务的状态
systemctl status cloudera-scm-server

# 查看系统日志
journalctl -xe 

# 默认日志存放地方
/var/log/cloudera-scm-server

3.8、访问服务

# 需要等几分钟 不要慌
http://woniu:7180

4、CDH优化

4.1、禁用透明大页面压缩

echo never>/sys/kernel/mm/transparent_hugepage/defrag

echo never>/sys/kernel/mm/transparent_hugepage/enabled

4.2、虚拟内存设置

# 查看虚拟内存需求率 默认60
cat /proc/sys/vm/swappiness

# Cloudera 建议将 vm.swappiness 修改为 0
sysctl -w vm.swappiness=0
echo "vm.swappiness = 0" >> /etc/sysctl.conf

5、Cloudera Manager 初始化集群配置

8、Inspect Cluster

先点击 Inspect Network Performance 再点击 Inspect Hosts

警告，点击显示检查器结果

已启用透明大页面压缩，可能会导致重大性能问题。请运行“echo never > /sys/kernel/mm/transparent_hugepage/defrag”和“echo never > /sys/kernel/mm/transparent_hugepage/enabled”以禁用此设置，然后将同一命令添加到 /etc/rc.local 等初始化脚本中，以便在系统重启时予以设置

echo never>/sys/kernel/mm/transparent_hugepage/defrag
 
echo never>/sys/kernel/mm/transparent_hugepage/enabled

点击重新运行
