# 禁止MySQL对外部连接进行DNS解析，使用这一选项可以消除MySQL进行DNS解析的时间。但需要注意，如果开启该选项，
# 则所有远程主机连接授权都要使用IP地址方式，否则MySQL将无法正常处理连接请求
max_connections=800
# MySQL的最大连接数，如果服务器的并发连接请求量比较大，建议调高此值，以增加并行连接数量，当然这建立在机器能支撑的情况下，因为如果连接数越多，介于MySQL会为每个连接提供连接缓冲区，就会开销越多的内存，所以要适当调整该值，不能盲目提高设值。可以过'conn%'通配符查看当前状态的连接数量，以定夺该值的大小。
max_connect_errors=1000
# 对于同一主机，如果有超出该参数值个数的中断错误连接，则该主机将被禁止连接。如需对该主机进行解禁，执行：FLUSH HOST。
