1. MySQ安装

1. 下载MySQL，前言链接有：

# 删除原有mariadb
rpm -qa |grep mariadb |xargs yum remove -y

# 解压
tar -xvf mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar


# 依次安装rpm
rpm -ivh mysql-community-common-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-embedded-compat-8.0.18-1.el7.x86_64.rpm
# devel博主安装失败了, 可以继续安装后面的
rpm -ivh mysql-community-devel-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.18-1.el7.x86_64.rpm


# 初始化
chmod -R 777 /var/lib/mysql
mysqld --initialize

# 启动，设置开机启动
systemctl start mysqld.service
systemctl enable mysqld.service

2. 查看数据库密码：
   
3. 登录MySQL：
   
4. 重新修改密码：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

设置其他用户或远程可登录：

create user 'root'@'%' identified with mysql_native_password by '123456';
grant all privileges on *.* to 'root'@'%' with grant option;
flush privileges;

不需要创建数据库可忽略

5. 创建Hive元数据库

CREATE DATABASE hive DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

6. 创建cdh 元数据库

CREATE DATABASE amon DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

7. Windows下使用Navicat测试：（填写IP，登陆密码）
   

2. 相关文章推荐

1. 安装Docker，脚本安装MySQL并启动
2. Docker安装、常用命令
3. Docker安装MySQL、Redis、RabbitMQ、ElasticSearch、Zookeeper

完！
