tar xvf yum-3.2.28.tar.gz
yum

9.安装jdk

 yum  install  -y  java-1.8.0-openjdk.x86_64
 java -version

10.安装mysql

rpm -qa|grep mysql
rpm -qa|grep mariadb
rpm -e --nodeps mysql-libs-5.1.73-1.el6.x86_64
rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64
chmod -R 777 /tmp
rpm -qa|grep libaio
rpm -qa|grep net-tools
yum -y install libaio net-tools
mkdir /opt/app/mysql
cd /opt/app/mysql
wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar
tar -xvf mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar
rpm -ivh mysql-community-common-5.7.16-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-5.7.16-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.16-1.el7.x86_64.rpm 
rpm -ivh mysql-community-server-5.7.16-1.el7.x86_64.rpm
验证：mysqladmin –version 
mysqld --initialize --user=mysql
cat /var/log/mysqld.log | tail -n 10
查看密码，如果有特殊字符，使用转移字符”\“
systemctl start mysqld.service
systemctl status mysqld
systemctl list-unit-files|grep mysqld.service
systemctl enable mysqld.sercice
mysql操作
ALTER USER 'root'@'%' IDENTIFIED BY '123456';
select @@validate_password_policy;
SHOW VARIABLES LIKE 'validate_password%';
set global validate_password_policy=LOW; 
set global validate_password_length=6;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'27.155.84.54' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;

10. 搭建CDH
    参考wps

问题一：cdh安装hue测试失败
rpm -ivh mysql-community-libs-compat-5.7.16-1.el7.x86_64.rpm
