前几天
公司一台FreeBSD的机器当了，起不来
由于上面有数据
就把硬盘拔下来
插到一台linux的机器上
希望在linux上mount之
然后把数据备出来
看了看manual
mount -t ufs -o ufstype=44bsd /dev/ida/c0d1p1 /mnt
结果老出错
后来
mount -t ufs -o ufstype=44bsd,ro /dev/ida/c0d1p1 /mnt
OK
原来仅支持readonly
//faint
后来又看文档
发现大概可以用
mount -t u2fs
不过也没测过
在工作中
经常碰到要装php的情况
这种情况又不是单装php，而是跟很多其他程序联系在一起的
比如说mysql、apache
下载、解开php的源代码程序包
tar xzvf php-4.3.11.tar.gz
cd php-4.3.11
./configure –with-gd=/usr –enable-track-vars –with-apxs=/usr/local/apache/bin/apxs –with-jpeg-dir=/usr/lib –with-png-dir=/usr/lib –with-zlib-dir=/usr/lib –with-mysql
make
make install
这里如果是在linux(redhat)下的话
可能再装之前先装上一些必要的rpm包
比如gd、gd-devel、libjpeg、libjpeg-devel、libpng、libpng-devel、zlib、zlib-devel等等，如果用apt-get来装，会快很多
装完之后
修改apache配置文件/usr/local/apache/conf/httpd.conf
添加一句：
AddType application/x-httpd-php .php
重起apache
就OK了
首先，把便签文件同步到pc上，一般扩展名会叫pwi
然后，打开此便签文件(pwi)，缺省会用word打开
再接着，右击打开的文档上的小喇叭，在弹出的菜单里选“录音机文档 对象”–〉“编辑”，这样会弹出一个录音机窗口
再接着，再弹出的录音机窗口点击“编辑”菜单，选择“复制”，然后关闭此录音机窗口
再然后，“开始”–〉“程序”–〉“附件”–〉“娱乐”–〉“录音机”，打开一个录音机窗口
再选择录音机“编辑”菜单，选择“粘贴插入”
最后，再选菜单“文件”–〉“另存为”，保存成wav文件即可
有些开源的软件
在gcc2.96下能正确编译
但在gcc3下却不能编译通过
原因是gcc3和gcc2.96在分析程序文件的格式的时候不兼容（gcc3认为有些在gcc2.96下能正确编译的程序格式不对）
有什么方法解决这个问题呢
难道一定需要在操作系统上装上gcc2.96吗？
有没有什么工具能把gcc3认为不正确gcc2.96认为正确的软件的格式改成gcc3也能正确认识的工具吗
不懂
俺的机器web server是apache
前面用squid做了本地加速
本来跑得好好的
但当我用一套drupal4.6.1的代码跑多(2)个drupal站点的时候
却发生问题了
第二个站点的url(http://www.example2.com)老是显示第一个站点(http://www.example1.com)的内容
但是只要把squid停掉
把apache直接摆到前台
又没有问题
不知道为什么
郁闷

以后每次启动iptables就会自动读取配置文件(/etc/sysconfig/iptables)

或者是/etc/rc.d/init.d/iptables start手工启动
/etc/rc.d/init.d/iptables stop手工停止
今天晚上偶尔用drupal自带的搜索搜了一把
发现搜中文什么都出不来！！
有点慌了神
google了一把
发现大家都在说drupal的中文搜索不能用
还有的在说在中文字符串前后添加"*"就会好
但也有提到系统crontab任务的问题
于是我"管理"–>"设置"–>"搜索"一看
index果然还是0%
于是我照安装文档上讲的在系统的crontab表里加一条：
0 * * * * wget -O - -q http://www.techtips.cn/cron.php
并手工执行了几遍
wget -O - -q http://www.techtips.cn/cron.php
再看"管理"–>"设置"–>"搜索"
index到了100%
这会儿再在页面上搜索中文
一点问题都没有了
并不需要在中文字符串的前后添加"*"
公司在idc的机器很多都是用ilo来做远程管理的
但很多的机器的ilo都是没有注册过的(没输入过注册码)
因而不能显示图形
而目前的grub缺省都是显示图形的
当我们需要在grub中选择用单用户进系统的时候
grub是图形的
我们的ilo没输过license
不能显示图形
所以也不能进单用户
这样很麻烦
其实只需要改/etc/grub.conf文件
把其中"splashimage=(hd0,0)/boot/grub/splash.xpm.gz"(类似于这一行，以"splashimage="开头，splash.xpm.gz结尾)的这一行注释掉(注意：注释是在最前面加"#")
以root 登录，输入”grub”命令以后，就会看到如下的画面：
GRUB version 0.5.96.1 (640K lower / 3072K upper memory)
[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ]
grub>
以上看到的就是 grub 提示符，我们要在这个提示符下面安装GRUB。
grub> install (hd0,1)/boot/grub/stage1 d (hd0) (hd0,1)/boot/grub/stage2 p (hd0,1)/boot/grub/menu.lst
GRUB 分为两个主要的步骤， stage1 和 stage2。Stage1 是一段嵌入MBR 的迷你代码。Stage2 是主要部分，在 stage1 把控制权传递给它后，就由它来接管所有事情。
install 后面指定stage1 的位置，我们不仅说明了其分区
位置：(hd0,1)，因为 GRUB 能读取文件系统，所以还说
明了分区上目录位置：/boot/grub/stage1，d 参数表示 stage1 将寻找 stage2 所在的磁盘。接着就是 GRUB 的安装位置：(hd0) ，这里就是指安装在MBR。后面的参数指定 stage2 的位置：(hd0,1)，和 stage1 的定义一样。p 参数指定 menu.lst 文件的位置。
对于 /boot 作为单独的分区的例子，需要采用下面的命令行：
grub> install (hd0,1)/grub/stage1 d (hd0) (hd0,1)/boot/grub/stage2 p (hd0,1)/grub/menu.lst
以上例子假设 /boot 位于 (hd0,1) (也就是hda2)，而 / 位于(hd0,2) (也就是 hda3) ，我们不能用 ‘(hd0,2)/boot/grub/stage1′ ，因为GRUB 不知道 (hd0,1) 是 /boot ，所以必须首先指向挂接为 /boot 的分区，然后把目录指向那里。
