记一次win10 下安装 mysql8

 

社区版 https://dev.mysql.com/downloads/mysql/，选择 8.0版本。下载64位 zip 压缩包。

 

 

 

解压，新建my.ini文件。

[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=C:\mysql-8.0.28-winx64
# 设置mysql数据库的数据的存放目录
datadir=C:\mysql-8.0.28-winx64\data
# 允许最大连接数
max_connections=200
# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
max_connect_errors=10
# 服务端使用的字符集默认为UTF8
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[client]
# 设置mysql客户端连接服务端时默认使用的端口
port=3306
default-character-set=utf8

 

 

使用管理员权限启动cmd命令行窗口，cd目录到解压缩的路径下。

接下来执行初始化和安装为windows服务。红色标志的root的初始密码，要做记录。

测试连接

 

竟然报错。

继续使用管理员权限，执行cmd命令。

mysql> use mysql;
Database changed
mysql> alter user 'root'@'%' identified with mysql_native_password by '123456';
Query OK, 0 rows affected (0.00 sec)
 
 
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
 
 
mysql> quit
Bye

 

至此终于连接成功。
