mysql启动：
/usr/bin/mysqld_safe --datadir=/srv/mysql/myDB --log-error=/srv/mysql/logs/mysqld-myDB.log --pid-file=/srv/mysql/pids/mysqld-myDB.pid --user=mysql --socket=/srv/mysql/sockets/mysql-myDB.sock --port=3700
但是当我尝试做某事时：
ERROR 1548 (HY000) at line 1: Cannot load from mysql.proc. The table is probably corrupted
如何解决？
