進階使用PHP安裝PEAR

安裝之前要確定你有lynx和php-cli兩套件。
# apt-get install lynx
# apt-get install php-cli

好了，有lynx和php-cli兩套件後，開始安裝PEAR。
# lynx -source http://go-pear.org | php
Welcome to go-pear!

Go-pear will install the 'pear' command and all the files needed by
it. This command is your tool for PEAR installation and maintenance.

Go-pear also lets you download and install the PEAR packages bundled
with PHP: MDB2.

The 'pear' command is now at your service at /usr/share/php/bin/pear

** The 'pear' command is not currently in your PATH, so you need to
** use '/usr/share/php/bin/pear' until you have added
** '/usr/share/php/bin' to your PATH environment variable.

Run it without parameters to see the available actions, try 'pear list'
to see what packages are installed, or 'pear help' for help.

Thanks for using go-pear!

最後別忘了把剛剛改的/usr/share/php加到php.ini的inculde_path裡！very very important!

ubuntu 加裝可創造橋接式網路的套件

這個月我在UBUNTU的使用上有了重大的突破，
那就是設定橋接式網路成功了！
前幾篇的文章一直在談使用VirtualBox，創造出一個虚擬的作業系統出來，
但是安裝好了VirtualBox之後，在要設定橋接式網路之前，
有幾個套件要先裝好。分別是：uml-utilities 、 bridge-utils
裝好之後才可以使用 tunctl 和 brctl 這兩個指令

$sudo apt-get install uml-utilities bridge-utils

以下指令請以root身份執行！
1. 創造一個TAP接口，叫tap0
#tunctl -t tap0 -u username
username 要置換成你自己的帳號！

2. 創造出bridge，叫br0
#brctl addbr br0

3. 把真實網卡設成promiscuous模式，使得它能够接收及發送别的MAC
#ifconfig eth0 0.0.0.0 promisc

這個指令下完，你之前的網卡配置就消失了！
也就是說，此時你的網路會斷線。

4. 接下來mwv 要恢復你的網路連線，把你的真實網卡橋接到bridge br0
#brctl addif br0 eth0

5. 再把真實網卡的配置改到br0上，舉例來說，
若你的eth0的配置是IP：192.168.1.100 netmask：255.255.255.0 ，
而你的gateway：192.168.1.254

#ifconfig br0 192.168.1.100 netmask 255.255.255.0 up
#route add default gateway 192.168.1.254

若是網路是由DHCP配置,則執行
#dhclient br0

6. 最後把TAP接口加進 bridge ，啓動它。
#brctl addif br0 tap0
#ifconfig tap1 up

7. 記得ml更改/dev/net/tun的權限
#chmod 0666 /dev/net/tun

好了，相信你也己經迫不期待想裝個windows玩玩了吧！
有個小技巧分享，我發現在灌xp時，先把橋接式網路設上去，
會造成這個xp網路連線失敗，原因不明！
但我重新以的方式安裝好xp後，再來設定bridge方式上網，
奇也怪哉！就成功了！

參考看看吧！
