我在惠普服务器上安装了centos+nginx+mysql+php,跑的是康盛的DZX网站程序,从前两个月开始网站访问频繁出现断网情况,我的站是个小小的站,刚开始做,没什么访问量,服务器的负载很小,联通的15M带宽。

出现断网的情况后,服务器时候查看显示还在工作,但是当时远程不了,无法访问,只能请IDC机房重启服务器,重启服务器之后,问题消失。

请各位高手帮忙啊。谢谢!!!

没看出来什么地方有问题.
断网的时候,楼主把ifconfig网卡信息保存下,分析下.
另外,如果ipv6没用的话,先把v6禁用下

    谢谢老大费心查看!

可是如果断网了,我使用ssh远程登录不上啊

也没法保留ifconfig的数据呀

只是网站不能访问么?SSH可以连接么?整个机器死掉还是只有web服务挂掉?
建议检查下nginx日志,以及你其他开放服务的日志
不过根据你的描述,也有可能是网卡驱动问题。

是的,只是网站不能访问,但是SSH不能连接,服务器没有死掉,只有web服务挂掉

好的,我这就去查nginx日志
