1. MySQ安裝

1. 下載MySQL，前言鏈接有：

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

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


# 依次安裝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博主安裝失敗了, 可以繼續安裝後面的
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

# 啓動，設置開機啓動
systemctl start mysqld.service
systemctl enable mysqld.service

2. 查看數據庫密碼：
   
3. 登錄MySQL：
   
4. 重新修改密碼：

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

設置其他用戶或遠程可登錄：

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

不需要創建數據庫可忽略

5. 創建Hive元數據庫

CREATE DATABASE hive DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

6. 創建cdh 元數據庫

CREATE DATABASE amon DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

7. Windows下使用Navicat測試：（填寫IP，登陸密碼）
   

2. 相關文章推薦

1. 安裝Docker，腳本安裝MySQL並啓動
2. Docker安裝、常用命令
3. Docker安裝MySQL、Redis、RabbitMQ、ElasticSearch、Zookeeper

完！
