一、下載mysql 5.7.11 zip 安裝包
本機(jī)以win7 64位系統(tǒng)為例，如果是32位系統(tǒng)，請(qǐng)下載32位的安裝包
http://dev.mysql.com/downloads/mysql/
選擇 Windows (x86, 64-bit), ZIP Archive 下載包
二、解壓安裝包 ｜ Extracting the Install Archive
D:\victor.min\software\mysql-5.7.11-winx64 #我的解壓目錄
三、創(chuàng)建一個(gè)空文件夾，命名為data， 也可以隨便命名，用來存放數(shù)據(jù)
# 本機(jī)創(chuàng)建在 D:\victor.min\software\mysql-5.7.11-winx64 目錄下，所以最后會(huì)看到
D:\victor.min\software\mysql-5.7.11-winx64\data #此文件夾后面會(huì)有用到
四、配置一個(gè)自己的啟動(dòng)配置文件 ｜ Creating an Option File
如果自己用沒什么特別的，就把 D:\victor.min\software\mysql-5.7.11-winx64\my-default.ini 文件copy一份，重新命名為 my.ini ，修改里面的幾個(gè)參數(shù)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 為安裝文件解壓后的目錄 ｜ basedir和datadir 可以使用相對(duì)路徑
# basedir=./..
basedir=D:\\victor.min\\software\\mysql-5.7.11-winx64
# datadir 為用來存放數(shù)據(jù)的目錄
# datadir=./../data
datadir=D:\\victor.min\\software\\mysql-5.7.11-winx64\\data
# port 為端口號(hào)
port=3306
# mar_connections為最大連接數(shù)
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、初始化數(shù)據(jù)目錄 Initializing the Data Directory
當(dāng)然，按照mysql官方文檔給出的步驟還有一步 Selecting a MySQL Server Type，就是選擇用 mysqld 還是 mysqld-debug ｜命令如下
mysqld --defaults-file="D:\victor.min\software\mysql-5.7.11-winx64\my.ini" --initialize-insecure
注：
1、這個(gè)命令很重要，它會(huì)初始化 data 目錄，在執(zhí)行此命令前請(qǐng)先把data目錄下的所有文件先刪除，否則會(huì)失敗
2、可以選擇用 --initialize-insecure 或者 --initialize 來初始化，--initialize-insecure 初始化root密碼為空，如果用 --initialize來初始化，會(huì)產(chǎn)生一個(gè)隨機(jī)密碼
執(zhí)行成功后你會(huì)在data目錄 下看到 mysql，perofrmance_schema，sys目錄，同時(shí)還會(huì)有一些文件
六、安裝 mysql 服務(wù)
七、啟動(dòng) mysql 服務(wù)
到這里，mysql服務(wù)就啟動(dòng)好，我們就可以用root進(jìn)入 mysql
為了方便，最好將mysql配置到環(huán)境變量中去
后記：
如果中途有什么步驟失敗，一定要執(zhí)行 mysql 移除命令，然后刪除 data 目錄下的所有文件
特別提醒：5.7 和 5.6 不太相同，要自己初始化數(shù)據(jù) data 目錄，不然啟動(dòng)不會(huì)成功
mysql 安裝完后可能會(huì)用到的語句
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;
