今天早上發現學校server 執行速度變好慢，使用ssh登入，下個指令要等許久才有回應，初次判斷疑是硬碟滿了，但，下了 "df -h" 指令查了容量，容量尚有空間。接下來就依以下步驟來處理:
一、查尋那個service 占用了資源。
#top
發現是apache service 異常。
二、重新啟用apache.
# /etc/init.d/httpd restart
結果:無法啟用httpd。出現以下錯誤訊息:
正在啟動 httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs解決方法:
#ps -aux |grep httpd
出現「apache 30396 0.0 0.0 2056 784 ? Ss Nov15 0:03 ./httpd」訊息。
#kill -9 30396
強制停止 .httpd程序。
#/etc/init.d/httpd start
三、查詢 log
# vim /var/log/httpd/error_log
部份內容如下:

四、自製favicon.ico檔，並上傳至website 根目錄。
自製favicon.ico 網址，http://www.favicon.cc/
favicon.ico 說明文件:http://blog.miniasp.com/post/2007/12/17/Introduce-faviconico-and-important-concept.aspx
五、處理完成。問題暫時解決，再觀察該server，是否會再有其他問題。
