Prerequisite packages are:
- PHP >= 5.3 development resources
- GCC compiler (Linux/Solaris)
- Git (if not already installed in your system - unless you download the package from GitHub and upload it on your server via FTP/SFTP)
Specific packages for common platforms:
#Ubuntu
sudo apt-get install php5-dev libpcre3-dev gcc make php5-mysql
# Suse
sudo yast -i gcc make autoconf2.13 php5-devel php5-pear php5-mysql
# CentOS/RedHat/Fedora
sudo yum install php-devel pcre-devel gcc make
# Solaris
pkg install gcc-45 php-53 apache-php53
Creating the extension:
git clone --depth=1 git://github.com/phalcon/cphalcon.git
cd cphalcon/build
sudo ./install
Add extension to your php configuration:
# Suse: Add this line in your php.ini
extension=phalcon.so
# Centos/RedHat/Fedora: Add a file called phalcon.ini in /etc/php.d/ with this content:
extension=phalcon.so
# Ubuntu/Debian: Add a file called 30-phalcon.ini in /etc/php5/conf.d/ with this content:
extension=phalcon.so
# Debian with php5-fpm: Add a file called 30-phalcon.ini in /etc/php5/fpm/conf.d/30-phalcon.ini with this content:
extension=phalcon.so
安装phalcon之前必须安装php5-dev、libpcre3-dev、gcc、make、php5-mysql这几个库，用于编译phalcon以及phalcon的扩展依赖。
然后，从github上clone代码到本地，进入编译目录bulid，然后开始安装phalcon的扩展。下面就是安装的细节。

----------------------------------------------------------------------
Libraries have been installed in:
/var/www/phalcon/build/32bits/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.
Installing shared extensions: /usr/lib/php5/20121212+lfs/
Installing header files: /usr/include/php5/
Thanks for compiling Phalcon!
Build succeed: Please restart your web server to complete the installation
从上面我们可以得知上那个信息：
1、安装目录以及安装的是多少位的：
Libraries have been installed in:
/var/www/phalcon/build/32bits/modules
本次安装在 /var/www/phalcon/下面了，是32位。
2、扩展文件在哪里：
Installing shared extensions: /usr/lib/php5/20121212+lfs/
这个路径下放着php所有的扩展包文件（.so）
3、header文件在哪里：
Installing header files: /usr/include/php5/
该路径下放着ext 、include、 main 、 sapi 、TSRM、 Zend等接口。
最后，根据上面的信息，我们还必须将这个扩展文件配置到php的环境中，如果你希望配置到php.ini文件，就打开 /etc/php5/fpm/php.ini文件，将
extension=phalcon.so添加到该文件即可，重启php5-fpm.
这里我不推荐直接编辑到php.ini文件，可以在/etc/php5/mods-available下面城建一个phalcon.ini文件，内容为extension=phalcon.so，然后建立软链接。
:/etc/php5/cli/conf.d# ln -s ../../mods-available/phalcon.ini 20-phalcon.ini
:/etc/php5/fpm/conf.d# ln -s ../../mods-available/phalcon.ini 20-phalcon.ini
注意，路径已经在php5的安装路径下了。
