### 1.下载MySQLzip包，并解压到你要安装的地方。
mysql下载地址[https://dev.mysql.com/downloads/mysql/](https://dev.mysql.com/downloads/mysql/)
注意：data目录是我创建的
### 2.在这个目录下创建my.ini文件，并输入以下内容
```properties
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
[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
```
注意：里面的 basedir 是我本地的安装目录，datadir 是我数据库数据文件要存放的位置，各项配置需要根据自己的环境进行配置。
查看所有的配置项，可参考：[https://dev.mysql.com/doc/refman/8.0/en/mysqld-option-tables.html](https://dev.mysql.com/doc/refman/8.0/en/mysqld-option-tables.html)
### 3.初始化数据库
输入cmd，以管理员身份运行控制台，进入MySQL路径（D:\\soft\mysql\mysql-5.7.29\bin）下，运行`mysqld --initialize --console`命令。进行初始化，如下：
