Now modify the /etc/sysctl.conf,but with a backup named /etc/sysctl.bak
Modifing the /etc/sysctl.conf has been succeed.
Now make the changes take effect.....

解决办法

[root@monitoring scirpts]# modprobe bridge
[root@monitoring scirpts]# lsmod|grep bridge
bridge                 85372  0 
stp                     2139  1 bridge
llc                     5560  2 bridge,stp
ipv6                  333206  28 bridge,ip6t_REJECT

再次执行命令

[root@monitoring scirpts]# sysctl -p
