[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:\\MySQL\\mysql1
# 设置mysql数据库的数据的存放目录
datadir = D:\\MySQL\\mysql1\\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
[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

4.使用cmd管理员模式进入mysql的bin目录下

复制代码

cd D:\MySQL\mysql1\bin

5.执行数据库初始化

复制代码

mysqld --initialize --console

@localhost:密码

这个密码一定要记住

6.运行安装服务

复制代码

mysqld.exe -install

复制代码

如果需要改服务名的话

复制代码

mysqld.exe -install MySQL2

7.运行

复制代码

net start mysql

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

复制代码

mysql -u root -p

输入刚刚保存的密码（这里只能手打不能粘贴）

此时已进入到mysql里面

选择数据库

复制代码

use mysql

更改user表中的host，把localhost改为%

复制代码

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

刷新权限

复制代码

flush privileges;

修改mysql登录密码（需要先登录）

复制代码

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

复制代码

mysql -u root -p
