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
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]
