MySql 5.6.12 安装笔记

MySQL版本：mysql-5.6.11-win32.zip （社区版）

操作系统：Win7 32bit， 和 Windows 2008 Server 32bit

MySql 的这个版本的安装与以往稍有不同，记录以备忘；

1.在Oracle网站上下载MySql，需要注册

2.解压到安装目录，比如这里是：D:\MySql\mysql5611

3.配置环境变量：新建一个系统变量： MYSQL_HOME， 值：D:\MySql\mysql5611

4.修改MySql启动配置文件： 将安装目录下文件：my-default.ini 重命名为 my.ini

5.修改my.ini， 比如这个：

# 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.
[mysql]
default-character-set=utf8

[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:\Mysql\mysql5611
datadir = d:\Mysql\mysql5611\data
default-storage-engine=MYISAM
port=3306
server-id=1
bind-address=0.0.0.0
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 

这里需要额外说明的是：

[mysql]
default-character-set=utf8

[mysqld]
character-set-server=utf8

这两个配置是为了保证中文的正常显示，根据需要修改为你期望的字符编码

[mysqld]
bind-address=0.0.0.0

这个配置是允许通过网络远程访问mysql服务，如果不去要，请删除此配置项，或者将地址改为：127.0.0.1

6.开始安装MySql
  a) 以管理员身份打开cmd，定位到安装目录/bin下
  b) 执行安装： mysqld --install MySql服务名
  c) 启动MySql服务： net start MySql服务名

7. mysql缺省的root密码为空，修改密码的一种方法是：
　　a) mysql -u root -p
   b) use mysql
   c) update mysql.user set password="new password" where User="root"; 
   d) flush privileges;

修改密码正确的SQL： SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');
