win7 mysql安装详解及报错解决

mysql准备

• 官网下载对应的zip包，我选择的(mysql-8.0.22-winx64.zip)
• 在mysql-8.0.22-winx64文件夹下面新建一个my.ini文件和一个data文件夹
• my.ini中的内容

my.ini内容：

[mysqld]
[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=E:\\app\\mysql-8.0.22-winx64
# 设置mysql数据库的数据的存放目录
datadir=E:\\app\\mysql-8.0.22-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
[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

• 我的电脑设置环境变量
  • MYSQL_HOME=e:\app\mysql-8.0.22-winx64
  • 在path中添加%MYSQL_HOME%\bin

mysql安装

• 已管理员身份打开cmd,输入mysqld --initialize --user=mysql --console发现弹出没有vcruntime140_1.dll文件
  • 找到对应网站下载此dll
• vcruntime140_1.dll文件放到C:\Windows\System32 和 C:\Windows\SysWOW64下
• 运行下面的bat文件，进行注册

@echo 开始注册
copy vcruntime140_1.dll %windir%\system32\
regsvr32 %windir%\system32\vcruntime140_1.dll /s
@echo system32 vcruntime140_1.dll注册成功

copy vcruntime140_1.dll %windir%\SysWOW64\
regsvr32 %windir%\system32\vcruntime140_1.dll /s
@echo SysWOW64 vcruntime140_1.dll注册成功
@pause

• 初始化数据库

• JoyfjqHL5)SO这个就是得到的数据库密码
• 输入命令安装mysql

E:\>mysqld install
Service successfully installed.

• 启动mysql服务

E:\>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功

• 登陆mysql,粘贴刚刚生成的密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

• 刷新FLUSH PRIVILEGES;
