紧急~为什么apache服务器运行速度奇慢？

afaf

我今天在公司服务器上安装了 Redhat linux AS3,并安装了mysql 3.2
开始还正常，不过过几分钟后访问速度奇慢，把httpd服务器重启动一下又好了，但过几分钟后还是奇慢。。。。下面是比较可疑的错误日记   error_log:

把HTTPD.CONF这个文件贴出来！是你的配置错误

shinesoft

netstat -al|grep SYN
看看,是不是有大量的SYN連接,如果是則極有可能是中了DDOS或DOS攻擊,去裝個APACHE的防DDOS模塊吧,moduls.apache.org上可以搜到dosevasive,安裝配置方法看里面自帶的說明文件吧.
