上回说道本地的mysql安装修改密码，连接本地的navicat 可能 还有些细节 或者不清楚的地方。今天抽空重新讲解下。
1.下载?mysql-5.6.17-winx64的zip. 放在目录里面，下面给出zip
2.解压当前的文件。
3.解压一堆文件之后，有bin 和 ?my-default.ini文件
我吧 修改后的my-default.ini 文件放在下面，先别忙着复制。里面有mysql的安装路劲。请参照你自己的安装路劲修改，不然启动不了。

[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%.

# 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.

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES?
?
在 bin 下启动doc窗口
?
输入：mysqld -install
显示： server successful..
?
启动mysql服务
net start mysql
?
注意：第一登陆进去是没有密码的。在mysql控制台下以root用户登录，默认root用户是没有密码的，直接按回车
命令：mysql -u root -p
?
修改密码?
使用mysqladmin命令，这里说明1234是你新设置的密码，可以根据需要设置自己的密码
mysqladmin -u root -p password 1234
按回车，然后输入你原先的密码，如果原来的密码为空，直接按回车就可以。
你的密码就设置成功。

退出 mysql ? : net stop mysql
