windows 安装mysql

首先去下载Mysql文件

我下载的是zip版本的

 2.解压文件

3.在解压的文件主目录下创建一个my.ini文件

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# 设置mysql的安装目录
basedir = D:\\soft\mysql\mysql-5.7.29
# 设置mysql数据库的数据的存放目录
datadir = D:\\soft\mysql\mysql-5.7.29\data
# 设置3306端口
port = 3306
# server_id = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

# 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 = utf8mb4
# 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
[mysql]
# 设置mysql客户端默认字符集
default-character-set = utf8mb4
[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 = utf8mb4

　　使用cmd进入解压出来的bin目录

cd C:\MySQL\mysql-8.1.0-winx64\Install\bin

　　初始话数据库

mysqld --initialize --console

　　这里会有一段话@localhost:xxxxx

　　这个xxxxx就是默认的初始密码，记得保存下来。

　　运行安装服务 

mysqld.exe -install

C:\MySQL\mysql-8.1.0-winx64\Install\bin>mysqld.exe -install

　　提示

Service successfully installed.

　说明服务安装成功

    再运行

net start mysql

C:\MySQL\mysql-8.1.0-winx64\Install\bin>net start mysql

 服务启动成功，

 到目前为止都安装完了

但是目前只能通过localhost也就是本机登录

继续cmd管理员模式进入安装目录的bin文件下

登录mysql

mysql -u root -p

输入刚刚保存的密码（这里只能手打不能粘贴）

选择“mysql”数据库

use mysql;

更新“user”表中root账号的host项

update user set host='%' where user='root';

刷新权限

flush privileges;

查看是否修改成功

select host,user from user where user='root';

完成！

修改登录密码（需要先登录）

alter user'root'@'localhost' identified with mysql_native_password by '你的密码';
