mysql 5.7.11 zip安装配置方法图文教程_Mysql

一、下载mysql 5.7.11 zip 安装包

本机以win7 64位系统为例，如果是32位系统，请下载32位的安装包

http://dev.mysql.com/downloads/mysql/

选择 Windows (x86, 64-bit), ZIP Archive 下载包

二、解压安装包 ｜ Extracting the Install Archive

1	`D:\victor.min\software\mysql-5.7.11-winx64 #我的解压目录`

三、创建一个空文件夹，命名为data， 也可以随便命名，用来存放数据

1 2	`# 本机创建在 D:\victor.min\software\mysql-5.7.11-winx64 目录下，所以最后会看到` `D:\victor.min\software\mysql-5.7.11-winx64\data` `#此文件夹后面会有用到`

四、配置一个自己的启动配置文件 ｜ Creating an Option File

如果自己用没什么特别的，就把 D:\victor.min\software\mysql-5.7.11-winx64\my-default.ini 文件copy一份，重新命名为 my.ini ，修改里面的几个参数就好了｜｜配置文件如下

									# 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.

									[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 = .....

									#########################

									# basedir 为安装文件解压后的目录 ｜ basedir和datadir 可以使用相对路径

									# basedir=./..

									basedir=D:\\victor.min\\software\\mysql-5.7.11-winx64

									# datadir 为用来存放数据的目录

									# datadir=./../data

									datadir=D:\\victor.min\\software\\mysql-5.7.11-winx64\\data

									# port 为端口号

									port=3306

									# mar_connections为最大连接数

									max_connections=20

									character_set_server=utf8

									# 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 

									explicit_defaults_for_timestamp=true

									sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

五、初始化数据目录 Initializing the Data Directory

当然，按照mysql官方文档给出的步骤还有一步 Selecting a MySQL Server Type，就是选择用 mysqld 还是 mysqld-debug ｜命令如下

1	`mysqld --defaults-file="D:\victor.min\software\mysql-5.7.11-winx64\my.ini"` `--initialize-insecure`

注：

1、这个命令很重要，它会初始化 data 目录，在执行此命令前请先把data目录下的所有文件先删除，否则会失败

2、可以选择用 --initialize-insecure 或者 --initialize 来初始化，--initialize-insecure 初始化root密码为空，如果用 --initialize来初始化，会产生一个随机密码

执行成功后你会在data目录下看到 mysql，perofrmance_schema，sys目录，同时还会有一些文件

六、安装 mysql 服务

1	`mysqld -install`

七、启动 mysql 服务

1	`net start mysql`

到这里，mysql服务就启动好，我们就可以用root进入 mysql

1	`mysql -u root -p`

为了方便，最好将mysql配置到环境变量中去

后记：

如果中途有什么步骤失败，一定要执行 mysql 移除命令，然后删除 data 目录下的所有文件

1	`mysqld -remove`

特别提醒：5.7 和 5.6 不太相同，要自己初始化数据 data 目录，不然启动不会成功

mysql 安装完后可能会用到的语句

									alter user 'root'@'localhost' identified by '123';

									create database victor;

									create user 'victor'@'localhost' identified by 'victor@123';

									flush privileges;

									creaet user 'victorremote'@'%' identified by 'victorremote@123';

									flush privileges;

									grant all on victor.* to 'victor'@'localhost' identified by 'victor@123';

									flush privileges;

									grant all on victor.* to 'victorremote'@'%' identified by 'victorremote@123';

									flush privileges;
