網站掛了

前幾天我的網站掛了,我一直以為是網路問題,沒特別去理會,到晚上還是連不上,才趕快通知我的系統服務商,創翔資訊,查了之後發現我的負載過高,CentOS 6掛點,趕快來查看我開了哪些服務, postfix 有開,所以立馬把它關掉,剩下的就是下面這些了.

<strong>#chkconfig --list | grep -u 3:on</strong>
<strong>auditd </strong>         0:off   1:off   2:on    3:on    4:on    5:on    6:off

<strong>network</strong>         0:off   1:off   2:on    3:on    4:on    5:on    6:off
<strong>openvpnas</strong>       0:off   1:off   2:off   3:on    4:on    5:on    6:off
<strong>rsyslog</strong>         0:off   1:off   2:on    3:on    4:on    5:on    6:off
<strong>sshd</strong>            0:off   1:off   2:on    3:on    4:on    5:on    6:off
<strong>udev-post</strong>       0:off   1:on    2:on    3:on    4:on    5:on    6:off
<strong>xe-linux-distribution</strong>   0:off   1:off   2:on    3:on    4:on    5:on    6:off

除了 crond(定時排程),httpd(網頁),iptables ip6tables(防火牆),mysqld(資料庫),network(網路),openvpnas(VPN),sshd(遠端登入),其他的我也搞不清楚,要找時間來決定是不是要關閉了.
