## 服务器 ##

天翼云：8核16g 40g 3M  
华为云：2核4g 40g 1M

## 步骤 ##

1.  查看公网  
    `curl ifconfig.me`
2.  查看内存  
    `free -m`
3.  防火墙  
    查看防火墙状态

systemctl status firewalld

永久关闭防火墙

systemctl disable firewalld

1.  查看时间

> date

1.  配置名称  
    配置本机名称

> echo node04 > /etc/hostname  
> vim /etc/sysconfig/network 注释掉第一行  
> HOSTNAME=node02 重启

6.配置hosts

vim /etc/hosts
    27.155.84.54 node01
    60.204.152.64 node02

1.  安装yum

cd /opt/app/yum
    wget http://yum.baseurl.org/download/3.2/yum-3.2.28.tar.gz
    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
    select @@validate_password_policy;
    SHOW VARIABLES LIKE 'validate_password%';
    set global validate_password_policy=0;
    set global validate_password_length=1;
    ALTER USER 'root'@'%' IDENTIFIED BY '123456';
    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;

1.  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
