☆☆☆☆☆☆☆ 一.Windows7下配置免安装版Mysql5.7.21 ☆☆☆☆☆☆☆

1.下载安装包

F:\mysql-5.7.21-winx64

3.新增mysql环境变量

MYSQL_HOME = F:\mysql-5.7.21-winx64

4.修改Path环境变量

Path变量下,末尾新增 ;%MYSQL_HOME%\bin;

5.手动新建相关文件夹/文件(文件内容为空即可)

F:\mysql-5.7.21-winx64\xudebiao

F:\mysql-5.7.21-winx64\xudebiao\data

F:\mysql-5.7.21-winx64\xudebiao\log

F:\mysql-5.7.21-winx64\xudebiao\log\mysql-error.log

F:\mysql-5.7.21-winx64\xudebiao\tmp

F:\mysql-5.7.21-winx64\xudebiao\tmp\mysql.sock

6.新建my.ini配置文件

# 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]

port=3306

socket=F:\mysql-5.7.21-winx64\xudebiao\tmp\mysql.sock

default-character-set=utf8

[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 = .....

# datadir = .....

# port = .....

# server_id = .....

# socket = .....

user=mysql

basedir=F:\mysql-5.7.21-winx64

datadir=F:\mysql-5.7.21-winx64\xudebiao\data

port=3306

socket=F:\mysql-5.7.21-winx64\xudebiao\tmp\mysql.sock

max_connections=1000

max_connect_errors=1000

table_open_cache=1024

max_allowed_packet=128M

character_set_server=utf8

collation-server=utf8_general_ci

lower_case_table_names=1

log_error=F:\mysql-5.7.21-winx64\xudebiao\log\mysql-error.log

slow_query_log=1

long_query_time=1

slow_query_log_file=F:\mysql-5.7.21-winx64\xudebiao\log\mysql-slow.log

symbolic-links = 0

# 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

7.准备工作做好的截图

8.执行安装命令

管理员身份运行"命令提示符"

进入F:\mysql-5.7.21-winx64\bin

第一步执行初始化操作: mysqld --initialize-insecure

第二步执行安装服务操作: mysqld install

第三步启动mysql服务: net start MySQL

【正常情况下这里会直接提示成功。如果失败了，上面第5步清空data（F:\mysql-5.7.21-winx64\xudebiao\data ）目录，再次执行命令】

9.修改初始密码

mysql -u root -p

第一次登陆没有密码, 输入密码的时候直接回车

set password = password('1990xxxx');

10.登陆测试

11.确认编码格式utf8

show variables like '%character%';

好了, 可以开车上路了~
