在Linux下安装PHP的PEAR，其实不复杂，怎么搜了一下，网上好多介绍，看起来都是一样的文章，其实很简单的。
1)下载
curl -o go-pear.php http://pear.php.net/go-pear
2)运行go-pear.php
debian:~# php go-pear.php
3)这里按回车继续安装，CTRL+C放弃安装。
If you wish to abort, press Control-C now, or press Enter to continue:
4)有没有代理，没有代理直接回车
HTTP proxy (http://user:password@proxy.myhost.com:port), or Enter for none::
安装路径，默认回车

1. Installation prefix ($prefix) : /root
2. Temporary files directory : $prefix/temp
3. Binaries directory : $prefix/bin
4. PHP code directory ($php_dir) : $prefix/PEAR
5. Documentation base directory : $php_dir/docs
6. Data base directory : $php_dir/data
7. Tests base directory : $php_dir/tests

1-7, ‘all’ or Enter to continue:

按Y
Would you like to install these as well? [Y/n] :
