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.minsoftwaremysql-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.minsoftwaremysql-5.7.11-winx64 目录下，所以最后会看到 D:victor.minsoftwaremysql-5.7.11-winx64data #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.minsoftwaremysql-5.7.11-winx64my-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.minsoftwaremysql-5.7.11-winx64my.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; ################################
show variables like 'collation_%';
show variables like 'character_set_%';
