1.文档编写目的


7月13日,Hortonworks在其官网宣布发布HDP3.0,相关介绍可以参考Fayson昨天的文章《Hortonworks正式发布HDP3.0》,最近又更新到了HDP3.0.1。本文档Fayson主要描述如何在Redhat7.4安装HDP3.0.1。HDP与CDH的安装步骤一致,主要包括以下四部分:

1.安全前置准备,包括安装操作系统、关闭防火墙、同步服务器时钟等;

2.外部数据库如MySQL安装

3.安装Ambari;

4.安装HDP集群;

  • 本次Fayson的测试环境为

1.Ambari2.7.1

2.HDP3.0.1

3.Redhat7.4

4.JDK1.8.0_141

5.MariaDB-5.5.56

6.root用户安装

2.前置准备

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,主机名通过/etc/hostname进行配置。

以Ambari节点(172.31.13.10)为例:

  • hostname配置

/etc/hostname文件如下:

ip-172-31-13-10.ap-southeast-1.compute.internal

(可左右滑动)

或者你可以通过命令修改立即生效

[root@ip-172-31-13-10 ~]$ hostnamectl set-hostname ip-172-31-13-10.ap-southeast-1.compute.internal

(可左右滑动)

  • hosts配置

/etc/hosts文件如下:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.31.13.10 ip-172-31-13-10.ap-southeast-1.compute.internal
172.31.15.170 ip-172-31-15-170.ap-southeast-1.compute.internal
172.31.8.219 ip-172-31-8-219.ap-southeast-1.compute.internal
172.31.0.246 ip-172-31-0-246.ap-southeast-1.compute.internal

(可左右滑动)

以上两步操作,在集群中其它节点做相应配置。确认需要安装的4台主机的hosts文件:

2.2.禁用SELinux


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

[root@ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "setenforce 0"

(可左右滑动)

集群所有节点修改/etc/selinux/config文件如下:

# 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

(可左右滑动)

2.3.关闭防火墙


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

[root@ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "systemctl stop firewalld"
[root@ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "systemctl disable firewalld"
[root@ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "systemctl status firewalld"

(可左右滑动)

2.4.集群时钟同步


在Redhat7.x的操作系统上,已经默认的安装了chrony,我们这里先卸载chrony,然后安装ntp。使用ntp来配置各台机器的时钟同步,将Ambari(172.31.13.10)服务作为本地ntp服务器,其它3台服务器与其保持同步。

1.所有机器卸载chrony

[root@ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "yum -y remove chrony"

(可左右滑动)

2.所有机器安装ntp

[root@ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "yum -y remove chrony"

(可左右滑动)

3.Ambari机器配置时钟与自己同步

[root@ ip-172-31-13-10 shell]# vim /etc/ntp.conf
#server 0.rhel.pool.ntp.org iburst
#server 1.rhel.pool.ntp.org iburst
#server 2.rhel.pool.ntp.org iburst
#server 3.rhel.pool.ntp.org iburst
server  127.127.1.0     # local clock
fudge   127.127.1.0 stratum 10

(可左右滑动)

4.集群其它节点,配置找Ambari机器去同步

#server 0.rhel.pool.ntp.org iburst
#server 1.rhel.pool.ntp.org iburst
#server 2.rhel.pool.ntp.org iburst
#server 3.rhel.pool.ntp.org iburst
server 172.31.13.10

(可左右滑动)

2.重启所有机器的ntp服务

[root@ ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "systemctl restart ntpd"
[root@ ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "systemctl status ntpd"

(可左右滑动)

6.验证始终同步,在所有节点执行ntpq -p命令,如下使用脚本批量执行

[root@ ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "ntpq -p"

(可左右滑动)

左边出现*号表示同步成功。

2.5.设置swap


所有节点执行

[root@ ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "echo vm.swappiness = 10 >> /etc/sysctl.conf"
[root@ ip-172-31-13-10 shell]# 

(可左右滑动)

2.6.设置透明大页面


所有节点执行:

[root@ ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list "echo never > /sys/kernel/mm/transparent_hugepage/defrag "
[root@ ip-172-31-13-10 shell]# sh ssh_do_all.sh node.list  "echo never > /sys/kernel/mm/transparent_hugepage/enabled"

(可左右滑动)

设置开机自关闭

将如下脚本添加到/etc/rc.d/rc.local文件中

if test -f /sys/kernel/mm/transparent_hugepage/enabled; then echo never > /sys/kernel/mm/transparent_hugepage/enabled fi if test -f /sys/kernel/mm/transparent_hugepage/defrag; then echo never > /sys/kernel/mm/transparent_hugepage/defrag fi

(可左右滑动)

同步到所有节点

2.7.配置操作系统repo


Fayson用的是AWS的环境,这步是可以省略的,放在这里供物理机部署的兄弟们参考。

  • 挂载操作系统iso文件
[ec2-user@ip-172-31-2-159 ~]$ sudo mkdir /media/DVD1
[ec2-user@ip-172-31-2-159 ~]$ sudo mount -o loop 
CentOS-7-x86_64-DVD-1611.iso /media/DVD1/

(可左右滑动)

  • 配置操作系统repo
[ec2-user@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/local_os.repo
[local_iso]    
name=CentOS-$releasever - Media
baseurl=file:///media/DVD1
gpgcheck=0
enabled=1
[ec2-user@ip-172-31-2-159 ~]$ sudo yum repolist

(可左右滑动)

2.8.安装http服务


  • 安装httpd服务
[ec2-user@ip-172-31-2-159 ~]$ sudo yum -y install httpd

(可左右滑动)

  • 启动httpd服务
[ec2-user@ip-172-31-2-159 ~]$ sudo systemctl start httpd

(可左右滑动)

  • 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
[ec2-user@ip-172-31-2-159 ~]$ sudo mkdir /var/www/html/iso
[ec2-user@ip-172-31-2-159 ~]$ sudo scp -r /media/DVD1/* /var/www/html/iso/
[ec2-user@ip-172-31-2-159 ~]$ sudo vim /etc/yum.repos.d/os.repo 
[osrepo]
name=os_repo
baseurl=http://172.31.2.159/iso/
enabled=true
gpgcheck=false
[ec2-user@ip-172-31-2-159 ~]$ sudo yum repolist

(可左右滑动)

2.9.安装MariaDB


1.安装MariaDB

[root@ ip-172-31-13-10 ~]# yum -y install mariadb
[root@ ip-172-31-13-10 ~]# yum -y install mariadb-server

(可左右滑动)

2.启动并配置MariaDB

[root@ ip-172-31-13-10 ~]# systemctl start mariadb
[root@ ip-172-31-13-10 ~]# /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 for
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 far
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!

3.建立Ambari,Hive等需要的用户和数据库

[root@ip-172-31-13-10 ~]# mysql -u root -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 9
Server version: 5.5.56-MariaDB MariaDB Server
