Linux uses mogilefs Distributed File system and uses Nginx to implement reverse proxy

MogileFS is a set of efficient file automatic backup components, developed by six apart and widely used in web2.0 sites including LiveJournal.
features of the mogilefs:
Work in the application layer, no single point, automatic file copy (the smallest unit of replication is class, not a file), transmission is neutral and is transmitted using NFS or the HTTP protocol.
the structure of the mogilefs consists of:

Tracker: Is the core of MogileFS, is a scheduler, through the database to save meta-information, including daemon,class,host and other information, the main responsibility: monitoring the backend Mogstore node, and instruct the store node to complete the data add, delete, query, And the replication between nodes.
Mogstore: Where the actual data is stored, usually pseudo an HTTP server.
Database: The global information used to hold the node.

1. install MogileFS  
A. Download mogilefs 
mogilefs-server:https://github.com/mogilefs/ mogilefs-server 
mogilefs-utils:https://github.com/mogilefs/mogilefs-utils 
perl-mogilefs-client:https://github.com/mogilefs/perl-mogilefs-client 
B. Install:  
Unzip the file and enter it in the file

[email protected] nginx-1.11.12]# make makefile.pl
[[email protected] nginx-1.11.12]# make && make install
[email protected] nginx-1.11.12]# Yum install perl-io-aio123123

2. configuration file Explanation

Parameter answer: Total dosage 8

3. Start and test

1. Create the/VAR/RUN/MOGILEFSD directory and modify the genus owner
[Email protected] mogilefs]# mkdir-p/VAR/RUN/MOGILEFSD
[Email protected] mogilefs]# chown-r mogilefs.mogilefs/var/run/mogilefsd/
2. Create the/mog/mogdata directory and modify the genus owner
[Email protected] mogilefs]# mkdir-p/mog/mogdata
[Email protected] mogilefs]# chown-r mogilefs.mogilefs/mog/mogdata/
3. Start the MOGILEFSD process and the mogstored process
[[Email protected] mogilefs]# service MOGILEFSD start
Starting MOGILEFSD
[[Email protected] mogilefs]# service mogstored start
Starting mogstored
* * The startup script here is installed with the RPM package and comes with a no service script that is typically installed using make

4. Configuring the Mogstord node host using the Administration tool

* * File Actual access location * *

Such a mogilefs distributed storage is set up, just the MOGILEFSD process and the mogstored process on the unified host.

7.use Nginx, now reverse proxy
using Nginx reverse proxy mogilefs, to use the third-party module in the implementation of the proxy, Nginx does not support the MogileFS agent, download module fast for nginx_mogilefs_module,:http:// Www.grid.net.ru/nginx/download/nginx_mogilefs_module-1.0.4.tar.gz

* * For detailed parameters, please refer to the official documentation: http://www.grid.net.ru/nginx/mogilefs.en.html**

8. Configure two MogileFS hosts
When two hosts are configured, the MOGILEFSD process reads the information of the Mogstord node in the database, which can be configured as described above in the configuration, recommended to be configured on one MOGILEFSD node, and the other node can be read in the database.
