先电大数据平台搭建

项目1

安装配置JDK

安装Tomcat

安装配置Eclipse

安装配置MySQL Server

安装Navicat

构建Hadoop开发平台

项目2

安装虚拟机（master和slave1）

启动虚拟机（master和slave1）

安装启动MobaXterm

配置主机名

设置ntpd自动启动

# master  
# yum -y install ntp  
# vi /etc/ntp.conf  
注释或者删除以下四行  
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  
添加以下两行  
server 127.127.1.0   
fudge 127.127.1.0 stratum 10   
#systemctl enable ntpd  
#systemctl start  ntpd  
# slave1 （timedatectl查看是否同步）  
# yum -y install ntpdate  
# ntpdate master  
# systemctl enable ntpdate

设置时间同步

（timedatectl查看是否同步）

设置免密登录

1.	检查2个节点是否可以通过无密钥相互访问，如果未配置，则进行SSH无密码公钥认证配置。如下：  
2.	# ssh-keygen  
3.	# ssh-copy-id root@master 
4.	# ssh-copy-id root@slave1
5.	# ssh-copy-id root@localhost
6.	ssh登录远程主机查看是否成功  
7.	# ssh master
8.	# exit  
9.	# ssh slave1  
10.	# exit

安装配置JDK

1.	# master   
2.	# mkdir /usr/jdk64/    
3.	# 将JDK复制到 /opt/下 
4.	# cd /opt/
5.	# tar -zxvf jdk-8u191-linux-x64.tar.gz -C /usr/jdk64/ 
6.	# vi /etc/profile  
7.	export JAVA_HOME=/usr/jdk64/jdk1.8.0_191  
8.	export PATH=$JAVA_HOME/bin:$PATH  
9.	# source /etc/profile  
10.	#java –version  
11.	# slave1  
12.	#mkdir /usr/jdk64/  
13.	    #Master: scp – r jdk64 slave1:/usr/jdk64/  
14.	# vi /etc/profile  
15.	export JAVA_HOME=/usr/jdk64/jdk1.8.0_191
16.	export PATH=$JAVA_HOME/bin:$PATH  
17.	# source /etc/profile  
18.	#java –version

安装Mysql

1.	# master  
2.	# yum install  mariadb mariadb-server mysql-connector-java -y 
3.	启动服务  
4.	# systemctl enable mariadb  
5.	# systemctl start mariadb  
6.	配置MySQL  
7.	#mysql_secure_installation  
8.	按enter确认后设置数据库root密码 
9.	如果报错， 请关闭防火墙  
10.	Remove anonymous users? [Y/n] y  
11.	Disallow root login remotely? [Y/n] n  
12.	Remove test database and access to it? [Y/n] y  
13.	Reload privilege tables now? [Y/n] y  
14.	创建ambari数据库  
15.	# mysql -uroot -pbigdata  
16.	MariaDB [(none)]> create database ambari;  
17.	MariaDB [(none)]> grant all privileges on ambari.* to 'ambari'@'localhost' identified by 'bigdata';  
18.	MariaDB [(none)]> grant all privileges on ambari.* to 'ambari'@'%' identified by 'bigdata';  
19.	MariaDB [(none)]> use ambari;  
20.	MariaDB [ambari]> quit

配置本地下载站

配置本地下载站

1.	# master  
2.	# yum -y install httpd  
3.	mkdir /var/www/html/ambari-hdp
4.	mkdir /var/www/html/ambari-hdp/HDP-UTILS
5.	将资源包ambari-2.6.0.0和HDP-2.6.1.0拖入/var/www/html/ambari-hdp目录，将资源包HDP-UTILS-1.1.0.21拖入/var/www/html/ambari-hdp/HDP-UTILS目录
6.	systemctl start httpd

配置Yum本地Repos资源池

由于yum源里面没有yum-plugin-priorities，则在网上下载，放入虚拟机手动安装

1.	rpm -ivh yum-plugin-priorities-1.1.31-519.fc30.noarch.rpm  
2.	vi /etc/yum/pluginconf.d/priorities.conf  
3.	[main]
