今天，在centos6下把mysql没法启动的数据库文件夹复制到/usr/local/mysql/var下，结果在修改表时，提示”table isreadonly”的错误。 首先想到的是遇到了权限问题，所以就去/usr/local/mysql/var查看了下，果然所有者不是mysql，权限也不正确。经过下面的步骤
把问题解决了：
1、进入mysql数据库目录，使用命令"chown -R mysql " 和 "chgrp -R mysql "将文件夹拥有者和所在组改为mysql
2、使用命令"chmod -R 760 " 改变权限设置
3、使用命令"mysqladmin -uroot -p reload"重新载入表
4、使用命令"mysqladmin -uroot -p flush-tables"执行刷新

提示: mysql数据库文件拥有者和所在组必须是mysql。
