二、底层环境准备

注：准备安装前需要把相关的包文件下载下来，并上传到服务器上

1、安装JDK

所有节点

1）安装系统原有java

# yum -y install java
# java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)
# rpm -qa|grep java
javapackages-tools-3.4.1-11.el7.noarch
python-javapackages-3.4.1-11.el7.noarch
java-1.8.0-openjdk-headless-1.8.0.91-0.b14.el7_2.x86_64
java-1.8.0-openjdk-1.8.0.91-0.b14.el7_2.x86_64
tzdata-java-2016d-1.el7.noarch

2）卸载OpenJDK

# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.91-0.b14.el7_2.x86_64
# rpm -e --nodeps java-1.8.0-openjdk-1.8.0.91-0.b14.el7_2.x86_64

3）安装下载的java

# rpm -ivh jdk-8u91-linux-x64.rpm

Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
# javac -version
javac 1.8.0_91

2、更改主机名和hosts

所有节点

注意每个主机名对应的IP，按实际情况更改。

# echo "bigdata0*.tfpay.com" > /etc/hostname
# echo "172.17.28.1    bigdata01.tfpay.com    bigdata01" >> /etc/hosts
# echo "172.17.28.2    bigdata02.tfpay.com    bigdata02" >> /etc/hosts
# echo "172.17.28.3    bigdata03.tfpay.com    bigdata03" >> /etc/hosts
# echo "172.17.28.4    bigdata04.tfpay.com    bigdata04" >> /etc/hosts

3、关闭防火墙

所有节点

# systemctl stop firewalld
# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.
# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

Jun 20 16:05:43 bigdata05.tfpay.com systemd[1]: Starting firewalld - dynamic firewall daemon...
Jun 20 16:05:45 bigdata05.tfpay.com systemd[1]: Started firewalld - dynamic firewall daemon.
Jun 20 16:17:51 bigdata05.tfpay.com systemd[1]: Stopping firewalld - dynamic firewall daemon...
Jun 20 16:17:52 bigdata05.tfpay.com systemd[1]: Stopped firewalld - dynamic firewall daemon.
# sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
# reboot

重启服务器使hostname和selinux的配置生效

# getenforce
Disabled
# sestatus -v
SELinux status:                 disabled

4、安装NTP服务

所有节点

# yum -y install ntp

更改配置文件/etc/ntp.conf

在master节点namenode节点

注释掉原有的server指向把时间服务器的域名地址指向一个靠谱可连的时间服务器，我选择的是ntp.api.bz.

# vi /etc/ntp.conf
    ……
     #server 0.centos.pool.ntp.org iburst
    #server 1.centos.pool.ntp.org iburst
    #server 2.centos.pool.ntp.org iburst
    #server 3.centos.pool.ntp.org iburst
    server ntp.api.gz iburst
    ......

在其余的节点上，把时间服务器的server指向master namenode节点

# vi /etc/ntp.conf
     ……
     #server 0.centos.pool.ntp.org iburst
    #server 1.centos.pool.ntp.org iburst
    #server 2.centos.pool.ntp.org iburst
    #server 3.centos.pool.ntp.org iburst
    server 172.17.28.1 iburst
    ......

所有节点

# systemctl start ntpd
# systemctl enable ntpd
Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service.

5、SSH无密码登陆

配置master namenode节点无密码登陆到其他节点

在master namenode节点

# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 回车
Enter passphrase (empty for no passphrase): 回车
Enter same passphrase again: 回车
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
bc:14:e2:59:42:1f:21:80:eb:49:d8:3b:7c:8d:b7:f9 root@bigdata05.tfpay.com
The key‘s randomart image is:
+--[ RSA 2048]----+
|   ...o o.       |
|  .  . o .       |
| o .  o +        |
|. +  . * .       |
| + o oo S        |
|  * o o. .       |
|   o . o.        |
|      o          |
|       .E        |
+-----------------+
# ssh-copy-id 172.17.28.2
# ssh-copy-id 172.17.28.3
# ssh-copy-id 172.17.28.4

6、安装数据库

master namenode节点

# yum -y install mariadb-server
# vi /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
character-set-server=utf8 \\添加的行
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
!includedir /etc/my.cnf.d
# systemctl start mariadb
# systemctl enable mariadb
ln -s ‘/usr/lib/systemd/system/mariadb.service‘ ‘/etc/systemd/system/multi-user.target.wants/mariadb.service‘
# mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found
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 \\设置数据库root密码
New password: \\设置密码
Re-enter new password: \\再次输入密码
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 \\移除匿名用户
... 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] y \\禁止root用户远程登录
... Success!
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 \\删除测试数据库
- 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] //
... 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!

数据库只是安装了一下，并没有做一些详细的配置。如果有需求可以另行配置。

7、其他安装与配置

所有节点

# yum  -y  install psmisc MySQL-python at bc bind-libs bind-utils cups-client cups-libs cyrus-sasl-gssapi cyrus-sasl-plain ed fuse fuse-libs httpd httpd-tools keyutils-libs-devel krb5-devel libcom_err-devel libselinux-devel libsepol-devel libverto-devel mailcap noarch mailx mod_ssl openssl-devel pcre-devel postgresql-libs python-psycopg2 redhat-lsb-core redhat-lsb-submod-security  x86_64 spax time zlib-devel

# systemctl start rpcbind
# echo "systemctl start rpcbind" >> /etc/rc.d/rc.local

三、开始安装CDH

1、传宝、解包

把下载好的一下相应包文件上传到master namenode节点内

mysql-java连接包在所有节点上都要上传

# ls
CDH-5.7.0-1.cdh5.7.0.p0.45-el7.parcel       cloudera-manager-centos7-cm5.7.0_x86_64.tar.gz  manifest.json
CDH-5.7.0-1.cdh5.7.0.p0.45-el7.parcel.sha1     jdk-8u91-linux-x64.rpm        mysql-connector-java-6.0.2.jar
# tar zxvf cloudera-manager-centos7-cm5.7.0_x86_64.tar.gz -C /opt/
# ls /opt/
cloudera  cm-5.7.0

2、创建数据库
