Cloudera（CDH）简介

官方文档https://www.cloudera.com/documentation/enterprise/latest.html CDH(Clouder's Distribution Including Apache hadoop)，基于web的用户界面，支持大多数Hadoop组件，包括HDFS、MapReduce、Hive、pig、Hbase、Zookeeper、Sqoop,简化了大数据平台的安装和使用难度。

一、准备环境

1、4台虚拟机，8核32G，1T硬盘

node1的IP地址为：192.168.2.180 node2的IP地址为：192.168.2.181 node3的IP地址为：192.168.2.182 node4的IP地址为：192.168.2.183

2、关闭所有节点的selinux

vi /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled 
设置后需要重启才能生效，现在先不要重启机器

3、设置所有节点的hosts文件

[root@localhost ~]# echo "192.168.2.180 node0">> /etc/hosts
[root@localhost ~]# echo "192.168.2.181 node1">> /etc/hosts
[root@localhost ~]# echo "192.168.2.182 node2">> /etc/hosts
[root@localhost ~]# echo "192.168.2.183 node3">> /etc/hosts
[root@node0 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.2.180 node0
192.168.2.181 node1
192.168.2.182 node2
192.168.2.183 node3

4、关闭所有节点的防火墙和清空防火墙规则链

# systemctl stop firewalld

# systemctl disable firewalld

# iptables -F

5、关闭所有节点的selinux

[root@localhost ~]# cat /etc/selinux/config

# 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=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

重启服务器

# reboot

6、设置所有节点的时区一致及时钟同步

所有节点安装ntp # yum install -y ntp 选取node0为ntp的主节点 # vi /etc/ntp.conf

添加内容如下：

#添加一个网段
restrict 192.168.2.254 mask 255.255.255.0 nomodify notrap
#time    设置时间同步服务器
server 0.asia.pool.ntp.org
server 1.asia.pool.ntp.org
server 2.asia.pool.ntp.org
server 3.asia.pool.ntp.org
#当外部时间不可用时，可使用本地硬件时间
server 127.127.1.0 iburst #local clock

开启ntpd及查看状态

[root@node0 ~]# systemctl start ntpd
[root@node0 ~]# systemctl status ntpd
● ntpd.service - Network Time Service
Loaded: loaded (/usr/lib/systemd/system/ntpd.service; disabled; vendor preset: disabled)

验证 # ntpq -p

[root@node0 ~]# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
 y.ns.gin.ntt.ne .INIT.          16 u    -   64    0    0.000    0.000   0.000

设置开机自启动

# systemctl enable ntpd

其他从节点停止禁用ntpd服务

由于是新安装的服务，默认是不启动的。

# systemctl stop ntpd
# systemctl disable ntpd

node1、node2、node3分别同步node0的时间

# ntpdate node0

设置node1、node2、node3每天凌晨同步node0节点时间的计划任务

# crontab -e

添加如下内容

00 00 * * * /usr/sbin/ntpdate node0 >/dev/null &

7、每个节点部署JDK【Java的路径必须放在/usr/java下】

# mkdir /usr/java

# tar -xzvf jdk-8u181-linux-x64.tar.gz -C /usr/java/

# chown -R root:root /usr/java/jdk1.8.0_181

# echo "export JAVA_HOME=/usr/java/jdk1.8.0_181" >> /etc/profile

# echo "export PATH=/usr/java/jdk1.8.0_181/bin:${PATH}" >> /etc/profile

# source /etc/profile

# which java

8、MySQL数据库相关操作

创建CDH的元数据库和用户、amon服务的数据库及用户

[root@mysql5 ~]# mysql -uroot -p
Enter password:

mysql> grant all on amon.* to 'amon';

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

9、node0节点部署MySQL jdbc jar

# mkdir -p /usr/share/java/

# mv mysql-connector-java-5.1.47.jar /usr/share/java/mysql-connector-java.jar

二、CDH部署

1、离线部署cm server 及agent

所有节点创建目录及解压

# mkdir /opt/cloudera-manager

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

2、选择node0为cm server，不下载依赖包直接部署

# cd /opt/cloudera-manager/cm6.3.1/RPMS/x86_64 # rpm -ivh cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm --nodeps --force # rpm -ivh cloudera-manager-server-6.3.1-1466458.el7.x86_64.rpm --nodeps --force

[root@node1 x86_64]# rpm -ivh cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm --nodeps --force
warning: cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID b0b19c9f: NOKEY

Created symlink from /etc/systemd/system/multi-user.target.wants/cloudera-scm-server.service to /usr/lib/systemd/system/cloudera-scm-server.service.

3、所有节点（包含node0）为cm agent，不下载依赖包直接部署

# cd /opt/cloudera-manager/cm6.3.1/RPMS/x86_64 # rpm -ivh cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm --nodeps --force # rpm -ivh cloudera-manager-agent-6.3.1-1466458.el7.x86_64.rpm --nodeps --force

4、所有节点修改agent的配置，指向server的节点node0

# sed -i "s/server_host=localhost/server_host=node0/g" /etc/cloudera-scm-agent/config.ini

5、主节点修改server的配置

# vi /etc/cloudera-scm-server/db.properties

# Copyright (c) 2012 Cloudera, Inc. All rights reserved.
#
# This file describes the database connection.
#

# The database type
# Currently 'mysql', 'postgresql' and 'oracle' are valid databases.
com.cloudera.cmf.db.type=mysql

# The database host
# If a non standard port is needed, use 'hostname:port'
#com.cloudera.cmf.db.host=localhost
com.cloudera.cmf.db.host=192.168.2.240

# The database name
#com.cloudera.cmf.db.name=cmf

# The database user's password
#com.cloudera.cmf.db.password=
com.cloudera.cmf.db.password=Cnbisoft@123

# The db setup type
# After fresh install it is set to INIT
# and will be changed post config.
# If scm-server uses Embedded DB then it is set to EMBEDDED
# If scm-server uses External DB then it is set to EXTERNAL
#com.cloudera.cmf.db.setupType=INIT
com.cloudera.cmf.db.setupType=EXTERNAL

6、node0节点部署离线parcel源

安装httpd服务

# yum install -y httpd

部署离线parcel源

# mkdir -p /var/www/html/cdh6_parcel # mv CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel /var/www/html/cdh6_parcel/ # mv CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel.sha1 /var/www/html/cdh6_parcel/CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel.sha # mv manifest.json /var/www/html/cdh6_parcel/ 启动httpd，window查看 # systemctl start httpd # systemctl enable httpd http://192.168.2.180/cdh6_parcel/
