（转）Windows下面安装和配置MySQL(5.6.20)

原文地址：http://www.cnblogs.com/qiyebao/p/3887055.html

1.首先到http://dev.mysql.com/ 上下载windows版mysql5.6免安装zip包。然后将zip包解压到D:\mysql-5.6.20-winx64下。

2.复制mysql下的my-default.ini, 在同目录下创建my.ini. my.ini为mysql的配置。最简单的配置：

basedir=D:/mysql-5.6.20-winx64
datadir=D:/mysql-5.6.20-winx64/data

我的配置为：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/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]
character-set-server=utf8
# 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=D:/mysql-5.6.20-winx64
datadir=D:/mysql-5.6.20-winx64/data
port=13306
character-set-server=utf8
default-storage-engine=INNODB
innodb_data_home_dir=D:/mysql-5.6.20-winx64/data
innodb_data_file_path=ibdata1:12M:autoextend
innodb_log_group_home_dir=D:/mysql-5.6.20-winx64/data
innodb_buffer_pool_size=10240M
innodb_log_file_size=4G
# 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

3.设置环境变量PATH。将D:\mysql-5.6.20-winx64\bin加入path中。

4.CMD下面尝试启动mysqld --console,并将后台log输出在屏幕。

5.注册mysql为windows service. 以后可以使用windows service来安装mysqld和卸载mysqld的服务.

安装MySQL服务,进入D:\mysql-5.6.20-winx64\bin目录执行安装

mysqld install

卸载MySQL服务

mysqld remove

6.进入服务管理器

7.启动MySQL服务

8.net start mysql 启动mysql服务,net stop mysql 停止mysql服务

9.也可以使用mysqladmin命令关闭mysql服务。

10.使用root用户登录mysql数据库（密码回车就好）

如果MySQL的连接端口不是默认的3306，可以使用下面的命令

mysql -P13306 -u root -p

指定MySQL连接端口13306

如果MySQL的连接服务器IP不是本机或者用户名不支持本机登陆，可以使用下面的命令

mysql -h机器名或IP地址 -P13306 -u root -p

11.显示所有数据库

show databases;

12.修改root帐户的登陆密码1234：

GRANT ALL ON *.* TO 'root'@'localhost' IDENTIFIED BY '1234';

13.创建数据库需要指定中文编码方式

14.查看MySQL存储引擎

show engines;

15.创建mysql远程连接用户，设置最大权限和登陆密码。

GRANT ALL ON *.* TO 'sa'@'%' IDENTIFIED BY '1234' WITH GRANT OPTION;

还有一些测试mysql安装的命令：

最后设置打开死锁开关的命令:

set global innodb_print_all_deadlocks=on

查看开关是否已经打开的命令：

show variables like 'innodb_print_all_deadlocks'
