• 一： 关于CDH6.1.0 的介绍
• 二： 系统环境初始化
• 三： 安装CDH6.1.0所需环境
• 四： 配置CDH6.1.0的cloudera-manager安装

一：关于CDH6.1.0 的介绍

Cloudera在前天12月19日，对外宣布正式发布Cloudera Enterprise 6.1包含大数据生态版本如下:
1.组件版本：Kafka 2.0, Spark 2.4, HBase 2.1.1, Accumulo 1.9.2, SOLR 7.4
2.CDH免费版限制100个节点内
3.HDFS的纠删码完全支持，包括Hive，Navigator(auditing)，BDR，MR，Spark
4.对象存储支持：On-prem (Ceph), Cloud (ADLS gen 2)
5.Impala的多个distinct语句支持
6.Sqoop的HiveServer2与导入Parquet文件支持
7.OpenJDK支持

二：系统环境初始化

2.1: 系统环境介绍

系统：CentOS7.5X64
cat /etc/hosts 
192.168.20.111  NN01.yl.com    NN01 
192.168.20.112  SN01.yl.com    SN01 
192.168.20.113  NN01.yl.com    DN01
192.168.20.114  NN02.yl.com    DN02

2.2：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 
 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

2.3: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 root@192.168.20.111:/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. NN01.yl.com:
vim /etc/chrony.conf 增加
----
注释掉相关默认的server
server ntp1.aliyun.com iburst
allow 192.168.20.111/16
service chronyd start
chkconfig chronyd on 
2. SN01.yl.com---DN01.yl.com 同步NN01.yl.com
vim /etc/chrony.conf
----
注释掉默认的server
server 192.168.20.111 iburst
----
service chronyd stop 
service chronyd start 
chkconfig chronyd on

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

选择更多parcel

所有节点执行：
echo vm.swappiness = 10 >> /etc/sysctl.conf
 echo 10 >  /proc/sys/vm/swappiness
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
