Windows系统下MySQL的安装配置以及遇到的问题

1：在官网下载mysql软件包

https://dev.mysql.com/downloads/mysql/

下载window版本的软件包

2；配置mysqlini,其中basedir，和datadir需要按照自己的安装路径进行修改

[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
# 设置3306端口
port = 3306
# 设置mysql的安装目录
basedir=D:\\soft\mysql-5.7.23-winx64
# 设置mysql数据库的数据的存放目录
datadir=D:\\soft\mysql-5.7.23-winx64\data
# 允许最大连接数
max_connections=20
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB

3：初始化Mysql

mysqld --initialize --console

界面显示如下所示则表示初始化成功，如果出现错误，就把上面配置的datadir目录删掉重新初始化

4：安装mysql服务

D:\soft\mysql-5.7.23-winx64\bin>mysqld install mysql5.7.32
Service successfully installed.

如果显示已经安装了，就把mysql换成mysql***

5:启动刚刚安装的服务，注意这里的服务名称要和安装的一样，否则会报错

D:\soft\mysql-5.7.23-winx64\bin>net start mysql5.7.32
mysql5.7.32 服务正在启动 .
mysql5.7.32 服务已经启动成功。

6：首次登陆mysql服务，这里的密码是初始化的时候，console展示的密码==>h+YXvjpgH5*j

D:\soft\mysql-5.7.23-winx64\bin>mysql -u root -p
Enter password: ************
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.7.23
