大数据平台CDH6.3.2部署

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 root@192.168.100.11:/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
