标签（空格分隔）： 大数据平台构建

• 一： 环境初始化
• 二： 安装CDH6.3.2

一：环境初始化

1.1 环境介绍

系统：CentOS7.5X64

cat /etc/hosts 
----
192.168.11.160  dev01.lanxintec.cn
192.168.11.161  dev02.lanxintec.cn
192.168.11.162  dev03.lanxintec.cn
----

1.2：无密钥登录配置

做root用户无密钥认证

 ssh-keygen ---一直敲回车到最后

 cat id_rsa.pub >> authorized_keys 

chmod 600 authorized_keys
 将所有的公钥导入authorized_keys  分发到 所有的 机器的.ssh/ 下面

 然后测试

1.3:关闭 firewalld，iptables 与 selinux

所有节点都要配置：

yum install -y firewall* iptable* 

  (1) 关闭firewalld

 systemctl stop firewalld.service
 systemctl disable firewalld.service
 firewall-cmd --state

 (2) 关闭iptables 
 iptables -F
 systemctl stop iptables.service 
 service iptables save
 systemctl disable iptables.service 

 (3) 禁用 selinux 

  sed -i ‘/SELINUX/s/enforcing/disabled/‘ /etc/selinux/config  
  setenforce 0
  getenforce 0
  sestatus

  重启机器

  reboot

2.4：所有机器更改CentOS7.5x64的文件句柄数

vim /etc/security/limits.conf
---

*               soft    nofile          65535
*               hard    nofile          1029345
*               soft    nproc           unlimited
*               hard    nproc           unlimited
*               soft    memlock         unlimited
*               hard    memlock         unlimited

在其它 节点上面执行命令：

rsync -arvzP :/etc/security/limits.conf /etc/security/

同步limits.conf  文件

2.5 时间同步：

所有机器 yum install chrony*
1. dev01.lanxintec.cn---dev03.lanxintec.cn 同步阿里云的时间服务器:

vim /etc/chrony.conf 增加
----
注释掉相关默认的server
server ntp1.aliyun.com iburst

service chronyd start
chkconfig chronyd on 

service chronyd stop 
service chronyd start 
chkconfig chronyd on

2.6: cdh6.3.2 安装所需文件下载

2.7:安装jdk

所用大数据节点都要配置：jdk 

rpm -ivh oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm

vim /etc/profile

---
export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera

3.2 安装cloudera-server

yum install -y cloudera-manager-server

3.3 在 mysql 当中创建 CM 需要的注册库

# mysql -uroot -pflyfish225
mysql> create database cmf character set utf8;
mysql> grant all privileges on cmf.* to ‘cmf‘@‘%‘ identified by ‘cmf_1234‘ with grant option;
mysql> grant all privileges on cmf.* to ‘cmf‘@‘dev01.lanxintec.cn‘ identified by ‘cmf_1234‘ with grant option;

mysql> flush privileges;

3.4 注入CM-server库 与 CM-agent端的server

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql cmf cmf cmf_1234

四： 配置CDH6.3.2的cloudera-manager安装

4.1 安装启动CM

service cloudera-scm-server start 
cd /var/log/cloudera-scm-server/
tail -f cloudera-scm-server.log

五： 打开web 安装：

echo 10 >  /proc/sys/vm/swappiness
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled

echo "vm.swappiness = 10" >> /etc/sysctl.conf 
sysctl -p

vim /etc/rc.local
----
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
---

create database cdh_hive default character set latin1;
grant all privileges on cdh_hive.* to ‘hive‘@‘%‘ identified by ‘Hive_123‘ with grant option;
