mysql8.0 windows10 源码安装

my.ini配置：https://www.cnblogs.com/gne-hwz/p/9720519.html

1）mysql官网下载源码 https://dev.mysql.com/downloads/mysql/

 

2）安装与配置文件

在解压后的mysql包中新建 my.ini文件

 

 my.ini文件中需要添加的内容如下：

[client]
port=3306
default-character-set=utf8
 
[mysql]
default-character-set=utf8
 
[mysqld]
#端口
port=3306
# 软件路径
basedir="F:/Program Files/mysql-8.0.15-winx64"
# 数据保存位置
datadir="F:/Program Files/mysql-8.0.15-winx64/Data"
# 允许最大连接数
max_connections=5
# 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=3
# 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
# 默认使用“mysql_native_password”插件认证
default_authentication_plugin=mysql_native_password

3）数据库初始化

以管理员身份运行命令提示符，进入MySQL安装目录的 bin 目录下执行命令：mysqld --initialize --console，不知道怎么进入bin目录，可以去百度，这里就不详细说明

F:\Program Files\mysql-8.0.15-winx64\bin>mysqld --initialize --console
[Server] C:\Program Files\MySQL\bin\mysqld.exe (mysqld 8.0.11) initializing of server in progress as process 4984
[Server] A temporary password is generated for root@localhost: fQaP#D1RFMeF

4）安装和启动数据库服务

PS F:\Program Files\mysql-8.0.15-winx64\bin> mysqld --install
Service successfully installed.
PS F:\Program Files\mysql-8.0.15-winx64\bin> net start mysql
MySQL 服务正在启动 ..
MySQL 服务已经启动成功。

5）登陆和更换密码

在MySQL安装目录的 bin 目录下执行命令：mysql -u root -p，然后输入初始化时的到密码，进入成功之后，在MySQL中执行命令：ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码'；，如下图所示，成功修改密码

PS F:\Program Files\mysql-8.0.15-winx64\bin> mysql -uroot -p
Enter password: ************

可以用 命令查看一下默认安装的数据库：show databases

mysql> show databases
    -> ;

| mysql              |
