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
