mysql8.0中zip的安装方法

测试环境：

Windows10专业版
MySQL版本：mysql-8.0.21-winx64（MySQL下载地址）

步骤

1.解压

MySQL下载后是一个压缩包，我解压到了D盘，大家注意盘符问题，看好自己的。

2.配置文件

在这里边新建一个，my.ini文件，复制下边内容。

[mysqld]
default_authentication_plugin=mysql_native_password
# 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.
basedir=D:\mysql-8.0.21-winx64
datadir=D:\mysql-8.0.21-winx64\data(会自动生成data文件,主要修改这两行内容，复制后，记得将括号里的文字删除！！！）
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 
 
character-set-server = utf8mb4
 
performance_schema_max_table_instances = 600
table_definition_cache = 400
table_open_cache = 256
 
[mysql]
default-character-set = utf8mb4
 
[client]
default-character-set = utf8mb4

3.初始化mysql数据库

在MySQL安装目录的 bin 目录下执行此命令：

.\mysqld --initialize --console

初始化结束后，会出现root的初始密码，记住，随后需要用这个密码进行登录。

4.安装mysql服务

在MySQL安装目录的 bin 目录下执行此命令：

.\mysqld --install mysql

PS：安装完成后，切记不要忘了启动服务：
net start mysql
PS：注意！！若是出现了Install/Remove of the Service Denied!问题，将cmd.exe用管理员身份来进行登录，即可解决

5.登录修改密码

.\mysql -uroot -p

输入之前记录的初始密码

修改：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';（password是你设置的密码）

FLUSH PRIVILEGES;
