接下來一行一行的看

 首先訪問地址是：http://IP:端口/server-status，這是基本格式，若是你要啓用本頁面的自動刷新功能，能夠這樣http://IP:端口/server-status?refresh=10，表示每10秒鐘自動刷新本頁面。

接下來的3行

Apache Server Status for 
Server Version: Apache/2.2.9 (Debian) PHP/5.2.6-1+lenny8 with Suhosin-Patch 
Server Built: Apr 19 2010 19:57:58

表示服務的配置地址，版本，安裝日期等，不是重點略看一下。

接下來的是重點了

Current Time: Monday, 19-Jul-2010 05:58:58 MSD //表示blogguy.cn的服務器上的時間
Restart Time: Monday, 19-Jul-2010 05:49:34 MSD //上次重啓時間
Parent Server Generation: 0 //大概是這樣一個東西，apache在正常運行後，apache的父進程會重讀配置文件，若是配置文件有改動那麼就強制全部apache的子進程重啓，Parent Server Generation就是記錄這個重啓次數的。
Server uptime: 9 minutes 24 seconds //apache的持續運行時間，blogguy.cn剛重啓哈，才被卡死
5 requests currently being processed, 4 idle workers //當前任務運行情況，正在處理的請求是5個，空閒的活動是4個

 _K_W._W_KK......................................................

的含義是：

     _：等待連結中。
     S：啓動中。
     R： 正在讀取要求。
    W：正在送出迴應。
    K：處於保持聯機的狀態。
    D：正在查找 DNS。
    C：正在關閉連結。
    L：正在寫入記錄文件。
    G：進入正常結束程序中。
    I：處理閒置。
    .：尚無此程序。

 

PID Key:

24279 in state: _ ,   20020 in state: K ,   29820 in state: _ 
   29821 in state: W ,   7553 in state: _ ,   29830 in state: W 
   7560 in state: _ ,   20286 in state: K ,   20255 in state: K

描述的是每一個活動的狀態信息，前面的數字表明進程號

To obtain a full report with current status information you need to use the ExtendedStatus On directive.//若是你須要看到更加詳細的服務器狀態報告，你須要把相應的選項打開。意思是說，原本server-status還能夠提供一些選項給你看的，惋惜你沒有打開，若是你打開你能夠看到流量信息，cpu信息等。可是官方文檔說這樣會致使安全隱患。

vi /etc/apache2/apache2.conf

在文件中添加一句：ExtendedStatus On

/etc/init.d/apache2 restart 

重啓而後再訪問http://IP:端口/server-status，看看效果：
