我的docker随笔14:MySQL操作实例

2020-02-06 10:40 609 查看

本文使用docker运行MySQL,并进行简单的操作。

本文使用的MySQL为官方镜像,版本为5.7。下载镜像命令:

docker pull mysql:5.7

使用下面的命令运行容器,并设置root密码为123456。

run --name hi-mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql

进入容器:

docker exec -it hi-mysql bash

在容器中进入mysql命令行:

mysql -uroot -p123456

如成功会提示:

mysql: [Warning] Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 11

mysql>
后即可输入sql语句。sql语句使用分号“;”作为结束符号。

查看数据库:

mysql> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+
4 rows in set (0.00 sec)

创建数据库,名称为mydb:

mysql> CREATE DATABASE mydb;

选择mydb数据库:

mysql> USE mydb;

创建数据表user:

mysql> CREATE TABLE `user` (
`id` bigint(20) NOT NULL,
`email` varchar(255) DEFAULT NULL,
`first_name` varchar(255) DEFAULT NULL,
`last_name` varchar(255) DEFAULT NULL,
`username` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

查看user数据表字段内容:

mysql> DESC user;
+------------+--------------+------+-----+---------+-------+
| Field      | Type         | Null | Key | Default | Extra |
+------------+--------------+------+-----+---------+-------+
| id         | bigint(20)   | NO   | PRI | NULL    |       |
| email      | varchar(255) | YES  |     | NULL    |       |
| first_name | varchar(255) | YES  |     | NULL    |       |
| last_name  | varchar(255) | YES  |     | NULL    |       |
| username   | varchar(255) | YES  |     | NULL    |       |
+------------+--------------+------+-----+---------+-------+
5 rows in set (0.02 sec)

往user表插入数据:

mysql> INSERT INTO `user` (`id`, `email`, `first_name`, `last_name`, `username`)
VALUES(0,'li@latelee.org','Late','Lee','latelee');

查看已经插入了的数据:

mysql>  SELECT * FROM user;
+----+----------------+------------+-----------+----------+
| id | email          | first_name | last_name | username |
+----+----------------+------------+-----------+----------+
|  0 | li@latelee.org | Late       | Lee       | latelee  |
+----+----------------+------------+-----------+----------+
1 row in set (0.00 sec)

删除user表所有数据:

mysql> DELETE FROM user;

删除user数据表:

mysql> DROP TABLE user;

删除数据库mydb:

mysql> DROP DATABASE mydb;

退出mysql命令行:

exit

退出容器:

exit
