Linux environment Fastdfs Distributed File System and PHP extension library installation and configuration

introduction of Fastdfs

Fastdfs is an open source lightweight Distributed File system developed by HAPPY_FISH100, and she manages the files, including file storage, file synchronization, file access (file upload, file downloading), etc., which solves the problem of large capacity storage and load balancing. Especially suitable for the document as the carrier of online services, such as photo albums, video sites and so on. The FASTDFS server has two roles: Tracker (tracker) and storage node (storage). The tracker mainly does the dispatching work and plays the role of load balancing on the access. The system structure diagram looks like this:

Second, installation and configuration

The FASTDFS structure, including two servers, is described in the topology map for the Linux server cluster scenario--lvs+keepalived (1), based on the VMware Environment:

Tracker server:192.168.195.3 (port:22122)

Storage server:192.168.195.4 (port:23000)

1, install Fastdfs, download Fastdfs source package, Eg:fastdfs_v1.28.tar.gz,tracker server and Storage Server installation way, the process is as follows:

#wget http://fastdfs.googlecode.com/files/FastDFS_v1.28.tar.gz

#tar-ZVXF fastdfs_v1.28.tar.gz

#cd Fastdfs

#./make.sh (if HTTP support is required, remove "# with_httpd=1" in make.sh)

#./make.sh Install

#mkdir/etc/fdfs

#mkdir/home/yuqing/fastdfs

2, Start tracker server

#cp conf/tracker.conf/etc/fdfs/

#/usr/local/bin/fdfs_trackerd/etc/fdfs/tracker.conf

3, Start Storage server

#cp conf/storage.conf/etc/fdfs/

#/usr/local/bin/fdfs_storaged/etc/fdfs/storage.conf

Note: According to the real environment of their own modify tracker.conf and storage.conf, can also refer to the "Fastdfs configuration file detailed", this environment needs to be storage.conf Tracker_server value modified to 192.168.195.3 : 22122.

Installation and configuration of FASTDFS client PHP extension Library

Currently Fastdfs PHP extensions do not support the Windows platform, before installing PHP extensions, you should install the FASTDFS client (the client installation process Ibid.) and PHP, the extension library installation is as follows:

#cd php_client (enter FASTDFS installation package/fastdfs/php_client)

#/opt/php/bin/phpize

#./configure--with-php-config=/opt/php/bin/php-config

#make && make Install

#cp. /conf/client.conf/etc/fdfs/(Modify client.conf, eg:tracker_server=192.168.15.3:22122)

#cat Fastdfs_client.ini >>/opt/php/etc/php.ini

Modify the configuration items for php.ini, such as:

Fastdfs_client.tracker_group_count = 1

Fastdfs_client.tracker_group0 =/etc/fdfs/client.conf

Restart the Web server. Extension function Descriptions and program examples are already available in php_client.
