回答1:

You want to look at the 'account' level limitations:

http://dev.mysql.com/doc/refman/5.0/en/user-resources.html

You should already have a user for that database, and you can then set

MAX_QUERIES_PER_HOUR <number>
MAX_UPDATES_PER_HOUR <number>
MAX_CONNECTIONS_PER_HOUR <number>
MAX_USER_CONNECTIONS <number>

from a GRANT statement. (You dont need all of them, maybe just MAX_USER_CONNECTIONS)

回答2:

log in to your server as root user go to phpmyadmin in variables section you can change

MAX_USER_CONNECTIONS 

to a bigger number
