windows10安装mysql8

laotu | 2021/04/08, 03:22

一、下载mysql

1、下载mysql

mysql最新版本下载地址:https://dev.mysql.com/downloads/mysql/

mysql存档旧版下载地址:https://downloads.mysql.com/archives/community

2、解压mysql

将下载的mysql-8.0.22-winx64.zip文件解压到指定的目录并重命名,如:D:\wamp\mysql80,即为mysql的安装目录。

二、安装mysql

1、设置PATH环境变量,右键“我的电脑-高级系统设置-环境变量-系统变量-path”,双击编辑将mysql 安装目录D:\wamp\mysql80\bin加入path中。

2、右键点击windows10右下角开始菜单,选择以管理员运行powershell,命令行进入到mysql的安装目录:

> cd d:\wamp\mysql80\bin

3、初始化mysql:

>  .\mysqld --initialize --console

记下运行结果中随机生成的root密码,方便后期修改root密码。root@localhost: W/62jqidawwN

4、安装mysql服务:

> .\mysqld --install

5、启动mysql服务:

>net start mysql

6、登录、修改mysql密码:

>mysql -uroot -p

输入初始化的root密码

mysql>ALTER USER 'root'@'localhost' identified by '123456' PASSWORD EXPIRE NEVER;

mysql>flush privileges;

说明:mysql8.0开始密码认证插件默认为“caching_sha2_password”。但只有php7.1.20、7.1.21、7.1.22、7.2.8、7.2.9、7.2.10及php7.4以上版本才支持。除此,需要将mysql8.0的密码认证插件改为“mysql_native_password”。

mysql>ALTER USER 'root'@'localhost' identified with mysql_native_password by '123456';

mysql>flush privileges;

或者编辑mysql配置文件,更改默认的身份认证插件。在[mysqld]下添加:

default_authentication_plugin=mysql_native_password

7、开启php的mysql扩展,支持php连接mysql:

编辑d:/wamp/php72/php.ini,将extension=mysqli和extension=pdo_mysql前面的分号去掉后,重启apache:

>httpd -k restart

8、mysql8导入sql文件需指定字符编码,否则乱码报错:

>mysql -uroot -p --default-character-set=utf8mb4 testdb -e "source d:\test.sql"

如:mysql 8 ERROR 1064 (42000) at line  ': You have an error in your SQL syntax; check the manual that c

9.创建my.ini配置文件,内容如下:

# For advice on how to change settings please see

http://dev.mysql.com/doc/refman/5.7/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.


[client]

default-character-set = utf8mb4


[mysql]

default-character-set = utf8mb4


[mysqld]

# basedir = d:\wamp\mysql80

# datadir = d:\wamp\mysql80\data

# port = 3306

character-set-client-handshake = FALSE

character-set-server = utf8mb4

collation-server = utf8mb4_bin

init_connect = 'SET NAMES utf8mb4'

innodb_buffer_pool_size = 128M


join_buffer_size = 128M

sort_buffer_size = 16M

read_rnd_buffer_size = 16M


# 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 = .....

# datadir = .....

# port = .....

# 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
