没搞懂咋回事，虽然一直没限制搜索引擎的采集，但一直也没什么流量，今天服务器居然停止响应了，登上机器一查询，300多个连接进程，俺vps根本吃不消，看来配置还有待优化，重启服务后，流量还是洪水般的涌来，懒得限制了，这个月流量还有不少，痛并快乐着！
看看把我机器搞死的“罪魁祸首”，大部分都是微软的蜘蛛，I服了U，你丫能不能少开点进程采啊！
分享一条命令行，查看当前网页端口连接ip以及连接数：
netstat -nt | grep [你的服务器IP] | awk '{print $5}' | awk -F":" '{print $1}'| sort | uniq -c | sort -r -n
我在服务器上执行上面的命令，得到如下结果：
