一、安装
1、查看当前系统
uname -a

Linux poksi-test-2019 4.15.0-45-generic #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
2、更新服务器上的包索引
sudo apt-get update
3、安装mysql
sudo apt-get install mysql-server
4、执行安全设置
sudo mysql_secure_installation
显示如下
There are three levels of password validation policy:

按照提示选择密码等级，并设置root密码
二、创建新的数据库、用户并授权
1、登录mysql
mysql -u root -p
按提示输入root密码
root@poksi-test-2019:~# mysql -u root -p
Enter password:
2、创建数据库
create database retail_db character set utf8mb4;
3、创建用户
create user 'retail_u'@'%' identified by 'retail_PWD_123';
4、授权用户
grant all privileges on retail_db.* to 'retail_u'@'%';
flush privileges;
5、查看当前的数据库
show databases;
6、显示当前数据库的表单
show tables;
三、建表
CREATE TABLE user (
`id` char(32) COLLATE utf8mb4_unicode_ci NOT NULL COMMENT 'ID',
`area_code` varchar(20) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '' COMMENT '区号',
`phone` varchar(45) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '' COMMENT '电话',
`password` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '密码',
`real_name` varchar(45) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '真实名称',
`nick_name` varchar(45) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '昵称',
`sex` tinyint(2) DEFAULT '0' COMMENT '性别 (0 未知 1 男 2女)',
`integral` int(11) DEFAULT '0' COMMENT '积分',
`address` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '住址',
`photos` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '头像',
`email` varchar(45) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '邮箱',
`birthday` date DEFAULT NULL COMMENT '生日',
`regist_source` tinyint(2) DEFAULT '0' COMMENT '注册来源（0：adnroid；1：ios；2：web）',
`create_time` datetime DEFAULT NULL COMMENT '创建时间',
`create_user_id` char(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '创建人',
`update_time` datetime DEFAULT NULL COMMENT '修改时间',
`update_user_id` char(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '修改人',
`deleted` tinyint(1) DEFAULT '0' COMMENT '0正常 1删除',
PRIMARY KEY (`id`),
UNIQUE KEY `id_UNIQUE` (`id`),
UNIQUE KEY `phone_UNIQUE` (`phone`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci COMMENT='App用户'
四、检查mysql服务状态
先退出mysql命令行，输入命令
systemctl status mysql.service
显示如下结果说明mysql服务是正常的
