mysql安装教程保姆级

1.下载MySQL

①地址：https://downloads.mysql.com/archives/community/
②解压

2.创建install.bat

放在mysql>bin同目录下

@echo off
:: 获取绝对路径
set localpath=%~dp0
:: my.ini路径
set myinipath=%localpath%mysql\my.ini
:: 初始化my.ini
echo Initialize my.ini
echo [mysql] >>%myinipath%
:: # 设置mysql客户端默认字符集
echo default-character-set=utf8 >>%myinipath%
echo [client] >>%myinipath%
:: # 设置mysql客户端连接服务端时默认使用的端口
echo port=3306 >>%myinipath%
echo default-character-set=utf8 >>%myinipath%
echo [mysqld] >>%myinipath%
:: # 设置3306端口
echo port=3306 >>%myinipath%
:: # 设置mysql的安装目录
echo basedir=C:\\for_me\\mianAnZhuang\\mysql >>%myinipath%
:: # 设置mysql数据库的数据的存放目录
echo datadir=C:\\for_me\\mianAnZhuang\\mysql\\data >>%myinipath%
:: # 允许最大连接数
echo max_connections=200 >>%myinipath%\
:: # 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
echo max_connect_errors=10 >>%myinipath%
:: # 服务端使用的字符集默认为UTF8
echo character-set-server=utf8 >>%myinipath%
:: # 创建新表时将使用的默认存储引擎
echo default-storage-engine=INNODB >>%myinipath%
:: #设置用户密码过期时间
echo default_password_lifetime=0 >>%myinipath%

echo The installation path is added to the system variable PATH
setx path "C:\for_me\mianAnZhuang\mysql\bin;%path%" /m
echo Start the my.ini configuration
%localpath%mysql\bin\mysqld -install
C:
cd C:\for_me\mianAnZhuang\mysql\bin
mysqld --initialize
echo skip-grant-tables >>%myinipath%
echo Start the MySQL service
net start MySQL
echo Initializes MySQL users and permissions
:: 用户密码、权限初始化sql
mysql -u root < C:\mysql\init.sql
pause

3.init.sql 初始创建

放在mysql>bin同目录下 root密码初始化

flush privileges;
set password for root@localhost = password('root');
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
flush privileges;

4.环境变量配置

C:mysql\bin

5.运行 install.bat 管理员权限运行

6.连接成功

遇到的问题

Table ‘performance_schema.session_variables’ doesn’t exist以及后续升级mysql遇到的cannot select database 问题

解决方法：在my.ini中[mysqld]配置加上

show_compatibility_56 = ON
performance_schema

重新启动服务，即可。！！！
