create index on files which read only

在mysql中，Select之类的都正常，但在网页程序中提示：Table 'cdb_posts' is read only 给数据库目录的所属用户和组改为mysql，并加上777的权限，还是一样提示。 程序中使用root连接，也是一样的提示。 想用myisamchk来检查一下，也提示read only。 最终在这里找到了解决方法：http://www.mysqltalk.org/re-the-table-is-read-only-vt154092.html 引用 I just encountered a similar problem on one of my production servers this morning. (I'm still investigating the cause.) After doing a quick bit of Google-searching, this solved my problem: mysqladmin -u <username> -p flush-tables By the way: All directories in /var/lib/mysql should have 700 permissions (owned my the mysql user) and everything within those directories should be 660 (owned by the mysql user and mysql group). 运行flush-tables后，read only问题解决：） create index index_name on table(field)</username>
