在Debian10.0上部署mysql步骤

1、使用wget命令下载你所需要的mysql版本,这里用0.8.13-1_all为演示:wget http://repo.mysql.com/mysql-apt-config_0.8.15-1_all.deb。

2、下载完成后,用具有sudo权限的w用户安装mysql发行包:

sudo apt install ./mysql-apt-config_0.8.15-1_all.deb

系统将显示配置菜单,从中可以选择要安装的MySQL版本。

已预先选择MySQL 8.0,如果要安装MySQL 5.7,请选择MySQL Server & Cluster (Currently selected: mysql-8.0),然后选择首选的 MySQL版本

我们将安装MySQL 8.0版。按Tab选择OK,然后按Enter(如上图所示)。

如果不确定要选择哪个版本,请查阅要在服务器上部署的应用程序的文档。

3、使用以下命令更新软件包列表并安装MySQL服务器软件包:

sudo apt update
sudo apt install mysql-server

安装程序将要求您设置MySQL root密码。现在不要设置密码(将其保留为空白),我们将在下一部分中进行设置。

接下来,您将看到一条消息,通知您有关新的MySQL 8身份验证的信息。在选择默认的MySQL 8身份验证插件之前,请确保您的应用程序支持它。

安装完成后,MySQL服务将自动启动,您可以通过输入以下内容进行验证:

sudo systemctl status mysql

随后会出现如下内容:

● mysql.service - MySQL Community Server
   Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: en
   Active: active (running) since Fri 2019-07-26 13:23:25 PDT; 37s ago
   ...

运行mysql_secure_installation命令来设置root密码并提高MySQL安装的安全性:

sudo mysql_secure_installation

随后会出现如下内容:

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?

Press y|Y for Yes, any other key for No:

将要求您配置 VALIDATE PASSWORD PLUGIN ,该工具用于测试MySQL用户密码的强度。密码验证策略分为三个级别:低,中和强。如果您不想设置验证密码插件,请按ENTER

随后会出现如下内容:

Please set the password for root here.

New password:

Re-enter new password:

在下一个提示符下,将要求您为MySQL根用户(即为root)设置密码。

按如下操作,全都输入y

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.


Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.


Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.

All done!

要通过终端与MySQL交互,请使用mysql客户端,该客户端作为MySQL服务器软件包的依赖项安装。

如果您选择默认身份验证方法作为root用户类型登录MySQL服务器:

sudo mysql

否则,如果您选择传统身份验证方法登录,请输入:

mysql -u root -p

运行mysql_secure_installation脚本时,系统将提示您输入先前设置的root密码。输入密码后,将显示MySQL外壳,如下所示:

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 10
Server version: 8.0.17 MySQL Community Server - GPL
