FastDFS分布式文件客户端安装，以及fastdfsapi

要使php程序利用fastdfs上传文件，要做到以下几点

wget http://fastdfs.googlecode.com/files/fastdfs_client_php_v1.6.tar.gz

一，安装php的fastdfs扩展

cd /home/zhangy/FastDFS/php_client             #/home/zhangy/FastDFS  这个目录是fastdfs服务器源，解压目录
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install

二，配置fastdfs客户端，以及php.ini

vi /home/zhangy/FastDFS/conf/client.conf

network_timeout=60
base_path=/home/zhangy/FastDFS

tracker_server=192.168.1.17:22122

#standard log level as syslog, case insensitive, value list:
### emerg for emergency
### alert
### crit for critical
### error
### warn for warning
### notice
### info
### debug
log_level=info

#HTTP settings
http.tracker_server_port=8080

#use "#include" directive to include HTTP other settiongs
##include http.conf

vi /usr/local/php/lib/php.ini

在文件最后加上以下内容

extension = fastdfs_client.so
fastdfs_client.tracker_group_count = 1
fastdfs_client.tracker_group0 = /home/zhangy/FastDFS/conf/client.conf

重起apache或者nginx或者支持你php的东西

三，php fastdfsapi解压

tar zxvf fastdfs_client_php_v1.6.tar.gz

解压里面的东西，就是php版的api了.代码比较乱，如果在外面在套一层，在封装一下就挺完美的了，纯属个人观点。哈哈。

四，我一个同事又将它封装了 一下，在这儿借花献佛
