1、下载mysql安装包

访问官方下载页面下载bundle安装包
https://downloads.mysql.com/archives/community/

下载文件 然后解压

mkdir -p  /root/package/mysql/mysql-server_5.7.41-1debian10_amd64.deb-bundle

cd /root/package/mysql/

tar -xvf mysql-server_5.7.41-1debian10_amd64.deb-bundle.tar -C mysql-server_5.7.41-1debian10_amd64.deb-bundle/

解压后的文件如图

root@debian:~/package/mysql# tar -xvf mysql-server_5.7.41-1debian10_amd64.deb-bundle.tar -C mysql-server_5.7.41-1debian10_amd64.deb-bundle/

root@debian:~/package/mysql#

2、安装文档

https://dev.mysql.com/doc/mysql-installation-excerpt/5.7/en/linux-installation-debian.html

2.1、安装依赖包

apt-get install libaio1

2.2、安装MySQL包

2.2.1、预设置数据库参数

cd /root/package/mysql/mysql-server_5.7.41-1debian10_amd64.deb-bundle/

dpkg-preconfigure mysql-community-server_*.deb

此步骤会进行设定mysql的root账户密码
输入root账户密码

再次输入密码

按tab键 选中ok 回车

包文件如图所示

2.2.2、安装MySQL包

安装MySQL包
本次安装失败 是因为依赖关系缺少的依赖包未安装导致导致安装失败

此次安装是mysql数据库基本安装方式，只安装了这些包。没有安装开发包。

至此安装MySQL 5.7.41成功，查看MySQL服务状态，在安装时已经设置了开机自启动，不需要可以禁用。

systemctl status mysql.service

2.3、文件安装位置

Here are where the files are installed on the system:

• All configuration files (like my.cnf) are under /etc/mysql
• All binaries, libraries, headers, etc., are under /usr/bin and /usr/sbin
• The data directory is /var/lib/mysql

3、使用mysql 5.7.41 数据库

3.1、命令行登录MySQL 5.7.41 数据库

登录数据库root账户 密码是安装MySQL时设置的root账户密码

mysql -uroot -p

root@debian:~/package/mysql# mysql -uroot -p
Enter password:

3.2、navicat连接mysql 5.7.41 数据库

新建连接 选择mysql

点击 连接测试

报错

需修改以下2点配置解决

3.2.1、修改mysql配置文件允许监听所有网卡地址

原因是默认安装完mysql后 只允许在mysql服务器本机发起数据库连接

ss -anlp|grep 3306

本机可以通3306

外部机器不可以通3306

修改MySQL配置文件 使得MySQL监听在所有网卡上，也就是允许所有IP地址发起数据库连接

cp /etc/mysql/mysql.conf.d/mysqld.cnf /etc/mysql/mysql.conf.d/mysqld.cnf.bak

/etc/mysql/mysql.conf.d/mysqld.cnf

编辑MySQL配置文件

vi /etc/mysql/mysql.conf.d/mysqld.cnf

修改bind-address = 127.0.0.1

修改为：bind-address = 0.0.0.0

重启MySQL服务

systemctl restart mysql.service

再次查看监听配置

ss -anlp|grep 3306

navicat测试连接数据库 仍然报错

Windows机器telnet 数据库IP 3306 测试

3.2.2、修改配置允许使用mysql root用户连接数据库

修改配置允许使用mysql root用户连接数据库
登录MySQL数据库

mysql -uroot -p

修改修改配置使得可以允许外部所有IP地址发起数据库连接，用户是root 密码是password(安装时设置的MySQL的root账户密码) ，拥有所有库和表的访问权限。

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> commit;
Query OK, 0 rows affected (0.00 sec)

mysql>

navicat再次测试连接 连接成功

新建查询

3.3、mysql数据库常用命令<5.7.41版本>

3.3.1、初始化默认数据库

初始化默认数据库

mysqld --initialize --console

mysqld命令帮助查看：

mysqld --verbose --help|less
