一、下載mysql 5.7.11 zip 安裝包
本機以win7 64位系統為例，如果是32位系統，請下載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、創建一個空文件夾，命名為data， 也可以隨便命名，用來存放數據
| # 本機創建在 D:/victor.min/software/mysql-5.7.11-winx64 目錄下，所以最后會看到D:/victor.min/software/mysql-5.7.11-winx64/data #此文件夾后面會有用到 |
四、配置一個自己的啟動配置文件 ｜ 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 ，修改里面的幾個參數就好了 ｜｜ 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 可以使用相對路徑# basedir=./..basedir=D://victor.min//software//mysql-5.7.11-winx64# datadir 為用來存放數據的目錄# datadir=./../datadatadir=D://victor.min//software//mysql-5.7.11-winx64//data# port 為端口號port=3306# mar_connections為最大連接數max_connections=20character_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=truesql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES |
五、初始化數據目錄 Initializing the Data Directory
當然，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、這個命令很重要，它會初始化 data 目錄，在執行此命令前請先把data目錄下的所有文件先刪除，否則會失敗
