mysql 5.7.21 winx64绿色版安装配置方法图文教程

作者:袖梨 2022-06-29

本文记录了mysql 5.7.21安装配置方法,具体内容如下

1.下载

下载地址

解压到自己喜欢的一个位置即可(目录中不要包含中文)

如:D:Program Files

2.系统环境变量配置

(1)新增系统变量 

         变量名:MYSQL_HOME
         变量值:Mysql解压目录,如D:Program Filesmysql-5.7.21-winx64

(2)追加PATH         

         ;%MYSQL_HOME%bin;

3.配置my.ini文件

在解压根目录新建一个my.ini的文件

# 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.
 basedir = "D:Program Filesmysql-5.7.21-winx64"
 datadir = "D:Program Filesmysql-5.7.21-winx64data"
 port = 3306
 character_set_server = utf8
 
# 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

4.管理员方式启动命令提示窗符

进入mysql解压目录到bin目录下

如:D:Program Filesmysql-5.7.21-winx64bin

分别执行:

(1)初始化:mysqld -initialize-insecure

如果报错failed to set datadir to 则 执行一下  mysqld --initialize --user=mysql --console,再执行(1);

正确之后会在Mysql解压根目录生成data文件夹以及相关文件

(2)mysqld -install

*如提示Install/Remove of the Service Denied,说明不是已管理员的方式进入的命令提示符

(3)启动服务:net start mysql

(4)登陆,改密码 mysql -u root -p

【成功登陆的直接到(5)】

我的出现了

在my.ini中增加

重启服务,成功登陆

(5)执行改密码语句 (正常登陆的使用set password= password(‘新密码'); 

update user set authentication_string = password("新密码") where user='root';

(6)exit;  net stop mysql

(7)登陆成功的忽略这一步

到my.ini中注释掉

重启进入之后set password= password(‘新密码');

到此就可以正常使用了。

(8)测试 show databases;

5.写两个bat文件用于启动和关闭mysql服务

(1)启动mysql服务

@echo off
echo 确定要启动MySQL服务吗?
pause
net start mysql
echo 启动MySQL服务完成,请确认有没有错误发生。
Pause

保存为   mysql服务启动.bat   文件,运行时要以管理员方式运行

(2)关闭mysql服务

@echo off
echo 确定要关闭MySQL服务吗?
pause
net stop mysql
echo 关闭MySQL服务完成,请确认有没有错误发生。
Pause

保存为   mysql服务关闭.bat   文件,运行时要以管理员方式运行

MySql到此安装结束。
