Fedora16的mysql

系统默认安装的mysql怎么的不能启动,查看日志文件/var/log/mysql.log有

/usr/libexec/mysqld: Can't find file: './mysql/plugin.frm' (errno: 13)
120417 21:37:13 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

errno:13,perror 13打印出的错误信息为：OS error code 13: Permission denied。

发现是权限问题,将/var/lib/mysql文件夹递归设用户和用户组为mysql

chown -R mysql:mysql /var/lib/mysql/

问题解决.
