mysql 安装改变数据库路径出现的问题解决方法

在windows上安装MySQL时,刚装后一切正常,但出于数据安全考虑,想把数据库目录放在D:\mysql\data下,于是对my.ini进行修改,将datadir="C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\data"改为datadir="D:/mysql/data"。
修改后不能重启mysql服务。
查看错误记录中有提示:
[ERROR] Event Scheduler: Failed to open table mysql.event
经过查找资料,按以下步骤可以得到解决:
鼠标右键单击mysql服务(有的是MySQL55等)——》点击“属性”——》“登录”选项卡——》选择“本地系统帐户”单选按钮——》“应用”。

一般多出现与mysq低权限运行问题中,不建议使用本地系统账户运行mysql。

首先要保证你的my.ini配置文件没什么问题

下面小编给出两个方法:


Now we have at least 2 choices:
1. change the service user to: "local system" (as david trillo did)
or

用本地系统账户运行mysql,不要用低权限运行,这个肯定不好。



2. add to the data dir security properties the user: "network service",
with all rights.

意思就是给data目录权限,一般情况下我们的权限都是继承的,但如果先做了安全就会出现问题。

其实把mysql data目录给低权限用户加上 全部权限就可以了。

小编就是因为这个原因,以前都是什么都配置好才做安全。所以以后还是逐步做好。
