mysql 5.7.11 zip安装配置方法图文教程

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

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

# 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

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

mysqld -install

七、启动 mysql 服务

net start mysql 

到这里，mysql服务就启动好，我们就可以用root进入 mysql

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

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;
