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
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:
/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
ec2-user@ip-172-31-2-159 ~$ 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
/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。
在所有节点执行sudo setenforce 0 命令,此处使用批处理shell执行:
ec2-user@ip-172-31-2-159 ~$ 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
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:
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "sudo systemctl stop firewalld"
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "sudo systemctl disable firewalld"
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "sudo systemctl status firewalld"
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
[ec2-user@ ip-172-31-2-159 ~]$ sudo vim /etc/chrony.conf
server ip-172-31-2-159 iburst
#keyfile=/etc/chrony.keys
[ec2-user@ip-172-31-12-108 ~]$ 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
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "sudo systemctl restart chronyd"
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh node.list "chronyc sources"

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!

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
1.下载csd文件
[root@ip-172-31-2-159 ~]# 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
[root@ip-172-31-2-159 ~]# mv KUDU-5.10.0.jar /opt/cloudera/csd
3.修改权限
[root@ip-172-31-2-159 ~]# chown cloudera-scm:cloudera-scm /opt/cloudera/csd/KUDU-5.10.0.jar
[root@ip-172-31-2-159 ~]# chmod 644 /opt/cloudera/csd/KUDU-5.10.0.jar
4.重启Cloudera Manager服务
[root@ip-172-31-2-159 ~]# systemctl restart cloudera-scm-server
1.下载Kudu服务需要的Parcel包
[root@ip-172-31-2-159 ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/KUDU-1.2.0-1.cdh6.10.1.p0.66-el7.parcel
[root@ip-172-31-2-159 ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/KUDU-1.2.0-1.cdh6.10.1.p0.66-el7.parcel.sha1
[root@ip-172-31-2-159 ~]# wget http://archive.cloudera.com/kudu/parcels/5.10/manifest.json
2.将Kudu的Parcel包部署到http服务
[root@ip-172-31-2-159 ~]# mkdir kudu1.2
[root@ip-172-31-2-159 ~]# mv KUDU-1.2.0-1.cdh6.10.1.p0.66-el7.parcel* kudu1.2/
[root@ip-172-31-2-159 ~]# mv manifest.json kudu1.2
[root@ip-172-31-2-159 ~]# mv kudu1.2/ /var/www/html/
[root@ip-172-31-2-159 ~]# 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
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
