一：環境初始化

1.1 環境介紹

系統：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：無密鑰登陸配置

作root用戶無密鑰認證

 ssh-keygen ---一直敲回車到最後

 cat id_rsa.pub >> authorized_keys 

chmod 600 authorized_keys
 將全部的公鑰導入authorized_keys  分發到 全部的 機器的.ssh/ 下面

 而後測試

1.3:關閉 firewalld，iptables 與 selinux

全部節點都要配置：

yum install -y firewall* iptable* 

  (1) 關閉firewalld

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

 (2) 關閉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

  重啓機器

  reboot

2.4：全部機器更改CentOS7.5x64的文件句柄數

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 節點上面執行命令：

rsync -arvzP root@192.168.100.11:/etc/security/limits.conf /etc/security/

同步limits.conf  文件

2.5 時間同步：

全部機器 yum install chrony*
1. dev01.lanxintec.cn---dev03.lanxintec.cn 同步阿里雲的時間服務器:

vim /etc/chrony.conf 增長
----
註釋掉相關默認的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 安裝所需文件下載

http://archive.cloudera.com/gplextras/misc/ext-2.2.zip

2.7:安裝jdk

所用大數據節點都要配置：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
export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
---
source /etc/profile 

java -version

2.8 安裝mariadb-server

yum install -y mariadb-server 

service mariadb start

chkconfig mariadb on

mysql -uroot -pflyfish225

2.9配置 httpd 分發服務器

pre01.lanxintec.cn:

yum install -y httpd

vim /etc/httpd/conf/httpd.conf
----
修改/etc/httpd/conf/httpd.conf配置文件，在<IfModule mime_module>中修改如下內容

AddType application/x-gzip .gz .tgz .parcel
----
service httpd start 
chkconfig httpd start

作CM6.3.1 的 分發源

yum install -y createrepo

cd /var/www/html/cdh5.3.6

createrepo.

vim /etc/yum.repos.d/cloduera-manger.repo

------
[cmrepo]
name = cm_repo
baseurl =http://192.168.100.11/cdh6
enable = 1
gpgcheck = 0

-----
yum makecache fast

全部主機執行命令同步：
rsync -avrzP root@192.168.11.160:/etc/yum.repos.d/cloudera-manager.repo /etc/yum.repos.d/

yum makecache fast

2.10 配置mysql-jdbc

cd /usr/share/java/

cp -p mysql-connector-java-8.0.15.jar  mysql-connector-java.jar

三： 安裝CDH6.3.2所需環境

3.1:安裝所需依賴包

全部大數據節點都要安裝：

yum -y install chkconfig python bind-utils psmisc libxslt zlib sqlite cyrus-sasl-plain cyrus-sasl-gssapi fuse fuse-libs redhat-lsb postgresql* portmap mod_ssl openssl-devel python-psycopg2 MySQL-python

3.2 安裝cloudera-server

yum install -y cloudera-manager-server

3.3 在 mysql 當中建立 CM 須要的註冊庫

# 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庫 與 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安裝

4.1 安裝啓動CM

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

五： 打開web 安裝：

---

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;
create database cdh_oozie default character set utf8;
grant all privileges on cdh_oozie.* to 'oozie'@'%' identified by 'Oozie_123' with grant option;
create database cdh_hue default character set utf8;
grant all privileges on cdh_hue.* to 'hue'@'%' identified by 'Hue_123' with grant option;
create database cdh_rm default character set utf8;
grant all privileges on cdh_rm.* to 'rm'@'%' identified by 'Rm_123' with grant option;
flush privileges;
