FASTDFS Configuration Instructions

Prior to understanding the principle of Fastdfs, then familiar with the installation process, prepared three machines, a simulation client, an analog storage, a simulation tracker. Three machines are debian6, the system for minimal installation, first install the basic compilation environment: Apt-get install build-essential php5-dev libevent-dev download Fastdfs Source package:

wget http://fastdfs.googlecode.com/files/fastdfs_v3.05.tar.gz

To start the installation:

Tar zxvf fastdfs_v3. 05.tar. Gz
CD Fastdfs/
./make. Sh
./make. SH Install

After the installation is complete, the FASTDFS default profile is placed under the/etc/fdfs directory, containing client.conf http.conf mime.types storage.conf Tracker.conf five files, the startup of the FASTDFS process is differentiated by the loaded configuration file. The three configuration files are included in the source package. tracker.conf Configuration File Analysis:

#配置tracker. conf This configuration file is in effect because the configuration file needs to be specified when the FASTDFS server process is started, so the secondary configuration file needs to take effect. False is valid, and true is masked.

Detection status

Netstat -tupln | grep storage
#结果如下:

To test the upload file:

Fdfs_upload_file /etc/Fdfs/client. Conf client. Conf
#返回如下字符串
Group1/M00/xx/xx/cgegflaqafw4henaaaaco8wrbse16. conf

You can see the file in the 00/00 directory under the storage data directory, the file name is cgegflaqafw4henaaaaco8wrbse16.conf
