Linux Kernel Problem (系統時間的問題) (不斷重開機的問題acpi)
作者:洛離 日期:2008-08-09 02:59
今天遇到了幾個討厭的問題
1. 硬體時間跟系統時間
系統時間老是比硬體時間過的要快,找了幾篇文章後發現,原因在於CentOS把bios 時間當成UTC,再依據你的時區來加減時間。
所以我們要修改設定讓他不要再把bios 的時間當成UTC了。
ZONE="Asia/Taipei"
UTC=false
ARC=false
把UTC=true => 改成 UTC=false
2. 詭異的acpi (全稱應該是Advanced Configuration and Power Interface)
不知道為什麼當我這新裝好的Server 跑到
SMP alternatives: switching to SMP code
Booting processor 1/2 APIC 0x1
就會稍微停頓一下然後就重開了,整個拿他沒辦法。
再來拜了一下Google 大神,終於找到解決方法了。
那就是在kernel option 加上一個 acpi=off,關掉這詭異的acpi。
結果真的順暢的開機了,但是原因我仍然是不清楚...或許只是個bug吧,也不知道是主機板的bug還是os的bug = =
最後發上兩個仙丹,以備不時之需。
如果Linux 順利無法開機進入系統的話 (非硬體問題),不妨先使用一下小萬靈丹acpi=off noapic,兩個選項一起用。
如果小萬靈丹用了還是無解的話,不妨再使用一下大萬靈丹 vga=normal ide=nodma apm=off acpi=off noresume nosmp noapic maxcpus=0 edd=off single
如果還是不行的話...另求高明吧...哈哈哈

1. 取消無用的服務
chkconfig mcstrans off
chkconfig netfs off
chkconfig ip6tables off
chkconfig haldaemon off
chkconfig messagebus off
chkconfig lvm2-monitor off
haldaemon 及 messagebus 如果有要使用 plug & play device,記得要打開。
vi /etc/inittab
# Run gettys in standard runlevels
1:2345:respawn:/sbin/mingetty tty1
2:2345:respawn:/sbin/mingetty tty2
#3:2345:respawn:/sbin/mingetty tty3
#4:2345:respawn:/sbin/mingetty tty4
#5:2345:respawn:/sbin/mingetty tty5
#6:2345:respawn:/sbin/mingetty tty6
不需要那麼多個終端。
2. 更新系統
yum update
如果有舊的kernel則移除舊的kernel
cd /boot
看套件有沒有把舊核心映像檔移除,沒有的話可手動移除
vi /grub/menu.lst
看grub 的設定有沒有問題。
搞定!

轉貼 http://www.albertsong.com/read-16.html
當點擊分類或者標籤時,F2Blog會列出該分類或標籤下的所有文章,但是大家抬頭看一看,會發現標題中並沒有該分類的名稱或標籤的名稱,這對搜索引擎評價網站內容有不利的影響。可以通過下面的方法修改。
打開includeloadbar.inc.php
在
//留言本和评论时装载cache.php
這句前面添加如下內容:
//生成分類,標籤標題
$job=(empty($_REQUEST['job']))?"":$_REQUEST['job'];
$_POST['seekname']=(empty($_POST['seekname']))?"":$_POST['seekname'];
$_GET['seekname']=(empty($_GET['seekname']))?"":$_GET['seekname'];
$seekname=($_POST['seekname']!="")?$_POST['seekname']:$_GET['seekname'];
switch ($job){
case "category":
$sql="select name from ".$DBPrefix."categories where id='$seekname'";
if ($arr_array=$DMC->fetchArray($DMC->query($sql))){
$borwseTitle=$arr_array['name'];
}
break;
case "tags":
$borwseTitle=$seekname;
break;
default:
break;
}

可以看出,F2Blog對SEO的支持還不夠,希望1.3版能有改善。

一、目標
一條獵狗將兔子趕出了窩,一直追趕它,追了很久仍沒有捉到。
牧羊犬看到此種情景,譏笑獵狗說:「那隻兔子身材比你小卻跑的比你快。」
獵狗回答說:「你不知道我們兩個跑的目的是完全不同的 !我僅僅為了一頓飯而跑,他卻是為了性命而跑呀!」
