mysql 5.7.16 winx64安装配置方法图文教程

针对之前安装mysql的笔记进行了总结，分享给大家。

版本：mysql-5.7.16-winx64
平台：windows 7 x64

1、进入mysql主目录（建议将其移到c或d盘的根目录，并改名为mysql)
2、配置path环境变量（如d:\java\mysql）添加到环境变量中。
3、mysql主目录下的my-default.ini文件改名为my.ini，最简单配置如下

# 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 = d:\java\mysql 
datadir = d:\java\mysql\data 
port = 3306 
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 
 
sql_mode=no_engine_substitution,strict_trans_tables 

如下图所示：

上图可见，mysql没有data目录，接下来我们需要初始化data目录
cmd下进入bin目录

4、运行：mysqld --initialize

5、安装mysql   mysqld install mysql --defaults-file="d:\java\mysql\my.ini"

6、启动mysql net start mysql

后记：
在初始化时如果加上 –initial-insecure，则会创建空密码的 root@localhost 账号，否则会创建带密码的 root@localhost 账号
密码保存在：data文件夹下的*.err文件中
：2016-11-25t04:05:29.713660z 1 [note] a temporary password is generated for root@localhost: /lseqhkou0x%
