Windows环境

MySQL8.0 zip安装方式

下载并解压

初始化配置文件

官方教程 (opens new window)

​ 1.bin同级目录新建my.ini文件,复制配置内容

[mysqld]
# 设置时区为东八区
default-time-zone='+08:00'
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=D:\mysql-8.0.27-winx64 
# 设置mysql数据库的数据的存放目录
datadir=D:\mysql-8.0.27-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
# 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=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

​ 2.修改basedir

​ 3.修改datadir

初始化数据库

​ 1.管理员打卡cmd，进入bin目录

​ 2.生成随机密码方式

mysqld   --initialize   --console

会得到一串临时密码，要保存！！！

3.不生成密码

mysqld   --initialize--insecure

安装mysql服务

1.输入命令

mysqld  --install  [MySQL3307]

默认名称是MySQL,

2.启动服务器

net  start  MySQL3307

3.关闭服务器

net stop MySQL3307

4.删除服务

SC DELETE MySQL3307

或者

mysqld --remove

进入mysql并修改密码

进入mysql

 mysql -u root -p

修改密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码'; 

MySQL5.7 zip安装

[mysql]
# 设置mysql客户端默认字符集
default-character-set = utf8

[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:\path-to-mysql
# 设置mysql数据库的数据的存放目录
datadir = D:\path-to-mysql\data
#设置3306端口
port = 3306
# server_id = .....

# 允许最大连接数
max_connections = 200
# 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

# 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 
# wait_timeout = 28800

需要保存为ANSI格式，其他操作步骤一样
