MySQL数据库如何使用Shell进行连接

目录

• 一、下载MySQL Shell
• 二、配置运行环境
• 三、连接MySQL数据库

在有些情况下我们需要使用命令行方式连接MySQL数据库，这时可以使用MySQL官方提供的命令行工具MySQL Shell。

一、下载MySQL Shell

下载地址：https://dev.mysql.com/downloads/shell/

注意下载地址为下面的Other Downloads，上面的Recommended Download是MySQL数据库的下载地址。

二、配置运行环境

下载后得到一个名为mysql-shell-8.0.19-windows-x86-64bit.zip的压缩包，将该压缩包解压后执行其bin目录下的mysqlsh.exe程序即可，为了方便也可以直接将程序路径添加到环境变量Path中，如下图所示。

打开Windows PowerShell或CMD窗口，输入mysqlsh --version，如果出现版本提示则表明环境变量配置成功。

PS C:Userszhbao> mysqlsh --version
D:Program FilesMySQLmysql-shell-8.0.19-windows-x86-64bitinmysqlsh.exe   Ver 8.0.19 for Win64 on 
x86_64 - for MySQL 8.0.19 (MySQL Community Server (GPL))

三、连接MySQL数据库

连接数据库的方法有两种，第一种是直接在命令行中输入mysqlsh命令和数据库地址等信息，然后根据提示输入密码即可。

PS C:Userszhbao> mysqlsh admin48@10.53.122.98:3360
Please provide the password for 'admin48@10.53.122.98:3360': ******
Save password for 'admin48@10.53.122.98:3360'? [Y]es/[N]o/Ne[v]er (default No): n

另一种方法是先输入mysqlsh启动程序，然后再通过connect命令连接数据库。

MySQL Shell默认是JS语言交互模式，可以通过sql命令切换到SQL语言交互模式。

MySQL  10.53.122.98:3360  JS > sql
Switching to SQL mode... Commands end with ;
 MySQL  10.53.122.98:3360  SQL >

接下来就可以通过SQL语言执行数据库命令了。
