对于运维人员来说，如果没有特别的需求，用源安装无疑是大家最愿意的选择。

常见的vps都是ubuntu10.04，其源中没有php5-fpm，安装的时候会提示：

Reading state information... Done
E: Couldn't find package php5-fpm

解决办法

1. 添加非官方的源到 /etc/apt/sources.list 

echo "deb http://ppa.launchpad.net/brianmercer/php/ubuntu lucid main" >> /etc/apt/sources.list 
echo "deb-src http://ppa.launchpad.net/brianmercer/php/ubuntu lucid main" >> /etc/apt/sources.list 

2. 安装php5-fpm 

sudo apt-get update && sudo apt-get install php5-fpm

3. 安装php扩展组件

sudo apt-get install php-apc php5-curl php5-gd php5-imagick php5-mysql\
 php5-memcache php5-memcached php5-mcrypt

4. 启动php-fpm

sudo  /etc/init.d/php5-fpm start

php.in位于/etc/php5/fpm/php.ini

php-fpm.ini位于/etc/php5/fpm/php5-fpm.conf

------------------------------------------
php-fpm启动时报错

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20060613+lfs/gd.so' - 
/usr/lib/php5/20060613+lfs/gd.so: undefined symbol: gdImageCreateFromJpeg in Unknown on line 0

locate libgd 查看gd的动态库位置,如果/usr/local/lib/目录里有则

rm /usr/local/lib/libgd*

重启php-fpm即可

去掉php-fpm启动时警告提示信息

PHP Deprecated:  Comments starting with '#' are deprecated in 
/etc/php5/fpm/conf.d/imagick.ini on line 1 in Unknown on line 0

把#变成;即可去掉该提示
