1.概述

本文档描述CENTOS7.2操作系统部署CDH企业版的过程。Cloudera企业级数据中心的安装主要分为4个步骤：

1.集群服务器配置，包括安装操作系统、关闭防火墙、同步服务器时钟等；
2.外部数据库安装
3.安装Cloudera管理器；
4.安装CDH集群；
5.集群完整性检查，包括HDFS文件系统、MapReduce、Hive等是否可以正常运行。

这篇文档将着重介绍Cloudera管理器与CDH的安装，并基于以下假设：

1.操作系统版本：CENTOS7.2
2.MariaDB数据库版本为10.2.1
3.CM版本：CDH 5.10.0
4.CDH版本：CDH 5.10.0
5.采用ec2-user对集群进行部署
6.您已经下载CDH和CM的安装包

2.前期准备

2.1.hostname及hosts配置

集群中各个节点之间能互相通信使用静态IP地址。IP地址和主机名通过/etc/hosts配置，主机名/etc/hostname进行配置。

以cm节点（172.31.2.159）为例：

  • hostname配置

/etc/hostname文件如下：

ip-172-31-2-159

或者你可以通过命令修改立即生效

[email protected] ~$ sudo hostnamectl  set-hostname ip-172-31-2-159

<font face="微软雅黑" size=4 color=red >注意：这里修改hostname跟REDHAT6的区别

  • hosts配置

/etc/hosts文件如下:

172.31.2.159 ip-172-31-2-159
172.31.12.108 ip-172-31-12-108
172.31.5.236 ip-172-31-5-236
172.31.7.96 ip-172-31-7-96

以上两步操作，在集群中其它节点做相应配置。

2.2.禁用SELinux

在所有节点执行sudo setenforce 0 命令，此处使用批处理shell执行：

[email protected] ~$ sh ssh\_do\_all.sh  node.list "sudo setenforce 0"

集群所有节点修改/etc/selinux/config文件如下：

SELINUX=disabled
SELINUXTYPE=targeted

2.3.关闭防火墙

集群所有节点执行 sudo systemctl stop命令，此处通过shell批量执行命令如下：

[[email protected] ~]$ sh ssh_do_all.sh node.list "sudo systemctl stop firewalld"
[[email protected] ~]$ sh ssh_do_all.sh node.list "sudo systemctl disable firewalld"
[[email protected] ~]$ sh ssh_do_all.sh node.list "sudo systemctl status firewalld"

2.4.集群时钟同步

在CentOS7.2的操作系统上，已经默认的安装了chrony，配置chrony时钟同步，将cm（172.31.2.159）服务作为本地chrony服务器，其它3台服务器与其保持同步，配置片段：

  • 172.31.2.159配置与自己同步

    [[email protected] ip-172-31-2-159 ~]$ sudo vim /etc/chrony.conf
server ip-172-31-2-159 iburst
#keyfile=/etc/chrony.keys
  • 集群其它节点：在注释下增加如下配置
[[email protected] ~]$ sudo vim /etc/chrony.conf
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server ip-172-31-2-159 iburst
#keyfile=/etc/chrony.keys
  • 重启所有机器的chrony服务
[[email protected] ~]$ sh ssh_do_all.sh node.list "sudo systemctl restart chronyd"

  • 验证始终同步，在所有节点执行chronycsources命令，如下使用脚本批量执行
[[email protected] ~]$ sh ssh_do_all.sh node.list "chronyc sources"

2.5.配置操作系统repo

  • 挂载操作系统iso文件

    [[email protected] ~]$ sudo mkdir /media/DVD1
[[email protected] ~]$ sudo mount -o loop
CentOS-7-x86_64-DVD-1611.iso /media/DVD1/

  • 配置操作系统repo 
    [[email protected] ~]$ sudo vim /etc/yum.repos.d/local_os.repo
[local_iso]
name=CentOS-$releasever - Media
baseurl=file:///media/DVD1
gpgcheck=0
enabled=1
[[email protected] ~]$ sudo yum repolist

2.6.安装http服务

  • 安装httpd服务
[[email protected] ~]$ sudo yum -y install httpd
  • 启动或停止httpd服务
[[email protected] ~]$ sudo systemctl start httpd
[[email protected] ~]$ sudo systemctl stop httpd
  • 安装完httpd后，重新制作操作系统repo，换成http的方式方便其它服务器也可以访问

    [[email protected] ~]$ sudo mkdir /var/www/html/iso
[[email protected] ~]$ sudo scp -r /media/DVD1/* /var/www/html/iso/
[[email protected] ~]$ sudo vim /etc/yum.repos.d/os.repo
[osrepo]
name=os_repo
baseurl=http://172.31.2.159/iso/
enabled=true
gpgcheck=false
[[email protected] ~]$ sudo yum repolist

2.7.安装MariaDB

  • 由于centos7默认使用的是5.5.52版本的MariaDB，此处使用的10.2.1版本，点击，在官网下载rpm安装包：

    MariaDB-10.2.1-centos7-x86_64-client.rpm
MariaDB-10.2.1-centos7-x86_64-common.rpm
MariaDB-10.2.1-centos7-x86_64-compat.rpm
MariaDB-10.2.1-centos7-x86_64-server.rpm

将包下载到本地，放在同一目录，执行createrepo命令生成rpm元数据。

此处使用apache2，将上述mariadb10.2.1目录移动到/var/www/html目录下, 使得用户可以通过HTTP访问这些rpm包。

[[email protected] ~]$ sudo mv mariadb10.2.1 /var/www/html/

安装MariaDB依赖

[[email protected] ~]$ yum install libaio perl perl-DBI perl-Module-Pluggable perl-Pod-Escapes perl-Pod-Simple perl-libs perl-version

制作本地repo

[[email protected] ~]$ sudo vim /etc/yum.repos.d/mariadb.repo
[mariadb]
name = MariaDB
baseurl = http://172.31.2.159/ mariadb10.2.1
enable = true
gpgcheck = false
[[email protected] ~]$ sudo yum repolist
  • 安装MariaDB

    [[email protected] ~]$ sudo yum -y install MariaDB-server MariaDB-client
  • 启动并配置MariaDB
[[email protected] ~]$ sudo systemctl  start mariadb

[[email protected] ~]$ sudo /usr/bin/mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS  RECOMMENDED FOR ALL MariaDB

       SERVERS IN PRODUCTION USE!   PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we‘ll  need the current

password for the root user.  If you‘ve just installed MariaDB, and

you haven‘t set the root password yet, the  password will be blank,

so you should just press enter here.

Enter current password for root (enter for none):  

OK, successfully used password, moving on...

Setting the root password ensures that nobody can  log into the MariaDB

root user without the proper authorisation.

Set root password? [Y/n] Y

New password:

Re-enter new password:

Password updated successfully!

Reloading privilege tables..

 ...  Success!

By default, a MariaDB installation has an  anonymous user, allowing anyone

to log into MariaDB without having to have a user  account created fo

them.  This  is intended only for testing, and to make the installation

go a bit smoother.  You should remove them before moving into a

production environment.

Remove anonymous users? [Y/n] Y

 ...  Success!

Normally, root should only be allowed to connect  from ‘localhost‘.  This

ensures that someone cannot guess at the root  password from the network.

Disallow root login remotely? [Y/n] n

 ...  skipping.

By default, MariaDB comes with a database named  ‘test‘ that anyone can

access.   This is also intended only for testing, and should be removed

before moving into a production environment.

Remove test database and access to it? [Y/n] Y

 - Dropping  test database...

 ...  Success!

 - Removing  privileges on test database...

 ...  Success!

Reloading the privilege tables will ensure that  all changes made so fa

will take effect immediately.

Reload privilege tables now? [Y/n] Y

 ...  Success!

Cleaning up...

All done!   If you‘ve completed all of the above steps, your MariaDB

installation should now be secure.

Thanks for using MariaDB!

5.Kudu安装

CDH从5.10开始，打包集成Kudu1.2，并且Cloudera正式提供支持。这个版本开始Kudu的安装较之前要简单很多，省去了Impala_Kudu，安装完Kudu，Impala即可直接操作Kudu。

以下安装步骤基于用户使用Cloudera Manager来安装和部署Kudu1.2

5.1.安装csd文件

1.下载csd文件

[[email protected] ~]# wget http://archive.cloudera.com/kudu/csd/KUDU-5.10.0.jar

2.将下载的jar包文件移动到/opt/cloudera/csd目录

[[email protected] ~]# mv KUDU-5.10.0.jar /opt/cloudera/csd

3.修改权限

[[email protected] ~]# chown cloudera-scm:cloudera-scm /opt/cloudera/csd/KUDU-5.10.0.jar
[[email protected] ~]# chmod 644 /opt/cloudera/csd/KUDU-5.10.0.jar

4.重启Cloudera Manager服务

[[email protected] ~]# systemctl restart cloudera-scm-server

5.2.安装Kudu服务

1.下载Kudu服务需要的Parcel包

[[email protected] ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/KUDU-1.2.0-1.cdh5.10.1.p0.66-el7.parcel
[[email protected] ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/KUDU-1.2.0-1.cdh5.10.1.p0.66-el7.parcel.sha1
[[email protected] ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/manifest.json

2.将Kudu的Parcel包部署到http服务

[[email protected] ~]# mkdir kudu1.2
[[email protected] ~]# mv KUDU-1.2.0-1.cdh5.10.1.p0.66-el7.parcel* kudu1.2/
[[email protected] ~]# mv manifest.json kudu1.2
[[email protected] ~]# mv kudu1.2/ /var/www/html/
[[email protected] ~]# systemctl start httpd

3.检查http显示Kudu正常：

4.通过CM界面配置Kudu的Parcel地址，并下载，分发，激活Kudu。

5.通过CM安装Kudu1.2

添加Kudu服务

选择Master和Tablet Server

配置相应的目录，<font face="微软雅黑" size=4 color=red >注：无论是Master还是Tablet根据实际情况数据目录(fs_data_dir)应该都可能有多个，以提高并发读写，从而提高Kudu性能

启动Kudu服务

安装完毕

5.3.配置Impala

在CDH5.10中，安装完Kudu1.2后，默认Impala即可直接操作Kudu进行SQL操作，但为了省去每次建表都需要在TBLPROPERTIES中添加kudu_master_addresses属性，建议在Impala的高级配置Kudu Master的地址：

--kudu\_master\_hosts=ip-172-31-2-159:7051

6.快速组件服务验证

6.1.HDFS验证(mkdir+put+cat+get)

[[email protected] ~]# hadoop fs -mkdir -p /lilei/test_table
[[email protected] ~]# cat > a.txt

0002-CENTOS7.2安装CDH5.10和Kudu1.2的相关文章

0002-CENTOS7.2安装CDH5.10和Kudu1.2(二)

5 Kudu安装 CDH从5.10开始,打包集成Kudu1.2,并且Cloudera正式提供支持.这个版本开始Kudu的安装较之前要简单很多,省去了Impala_Kudu,安装完Kudu,Impala即可直接操作Kudu. 以下安装步骤基于用户使用Cloudera Manager来安装和部署Kudu1.2 5.1 安装csd文件 5.2 安装Kudu服务 3.检查http显示Kudu正常: 4.通过CM界面配置Kudu的Parcel地址,并下载,分发,激活Kudu. 5.通过CM安装Kudu1.

0002-CENTOS7.2安装CDH5.10和Kudu1.2(一)

1 概述 本文档描述CENTOS7.2操作系统部署CDH企业版的过程.Cloudera企业级数据中心的安装主要分为4个步骤: 1.集群服务器配置,包括安装操作系统.关闭防火墙.同步服务器时钟等: 2.外部数据库安装 3.安装Cloudera管理器: 4.安装CDH集群: 集群完整性检查,包括HDFS文件系统.MapReduce.Hive等是否可以正常运行. 这篇文档将着重介绍Cloudera管理器与CDH的安装,并基于以下假设: 操作系统版本:CENTOS7.2 MariaDB数据库版本为10.

Centos7下安装mono3.10.0

mono 3.10.0 正式发布:性能进一步改进,以前已经写过一篇  Centos 7.0 安装Mono 3.4 和Jexus 5.6.下面我们在CentOS 7上通过源码安装Mono 3.10, 需要安装最新的libgdiplus3.8. 1. 安装依赖项 yum -y install wget glib2-devel libtiff libtiff-devel libjpeg libjpeg-devel giflib giflib-devel libpng libpng-devel libX

CentOS7.2 安装nginx-1.10.3

nginx-1.10.3 下载nginx 检查是否安装了依赖库: [[email protected] ~]# rpm -q gcc gcc-4.8.5-11.el7.x86_64 [[email protected] ~]# rpm -q openssl openssl-1.0.1e-60.el7_3.1.x86_64 [[email protected] ~]# rpm -q zlib zlib-1.2.7-17.el7.x86_64 [[email protected] ~]# rpm -

CENTOS7离线安装CDH5.6遇到的问题

1,安装cloudera-manager-agent 时,报错,报端口80问题, 开启80端口 firewall-cmd --zone=public --add-port=80/tcp --permanent 出现success表明添加成功 命令含义: --zone #作用域 --add-port=80/tcp  #添加端口,格式为:端口/通讯协议 --permanent   #永久生效,没有此参数重启后失效 运行.停止.禁用firewalld 启动:# systemctl start  fir

centos7+cdh5.10.0搭建

一.选择环境: 1.说明 本次部署使用台机器,3台用于搭建CDH集群,1台为内部源.内部源机器是可以连接公网的,可以提前部署好内部源,本次部署涉及到的服务器的hosts配置如下: 192.168.10.114    sp-04 192.168.10.115    sp-05 192.168.10.116    sp-06 本次安装为cdh5.10.0 需要centos版本: Jdk版本:jdk-8u73-linux-x64.tar 参考地址:https://www.cloudera.com/do

centos7.4下离线安装CDH5.7

(一)安装前的规划 (1)操作系统版本:centos7.4(64bit) [[email protected] etc]# more /etc/centos-release CentOS Linux release 7.4.1708 (Core) [[email protected] installPackage]# cat /proc/version Linux version 3.10.0-693.el7.x86_64 ([email protected]) (gcc version 4.8

cdh-5.10.0搭建安装

1.修改主机名为master, slave1, slave2 vim /etc/sysconfig/network HOSTNAME = master HOSTNAME = slave1 HOSTNAME = slave2 2.修改hosts文件(三个节点都要设置) vim /etc/hosts 192.168.1.7 master 192.168.1.8 slave1 192.168.1.9 slave2 3.IP设置(三个节点都要设置) DEVICE=eth0 HWADDR=4C:CC:6A

centos7.0安装apache-2.4.10

centos7.0安装完毕后,通过yum 安装的apache版本是 2.4.6的. 于是先停止了httpd服务,然后卸载了默认安装的版本. systemctl stop httpd.service rpm -qa|grep httpd #查看apache包,找到名字(例如httpd-2.4.6-18.el6_2.1.x86_64)后用下面命令删除 rpm -e httpd-2.2.15-15.el6_2.1.x86_64 #不过要先把依赖apache的包删除 或者 yum list|grep h
