Deploy social networking sites-SVN and LNMP architectures

Case overview

The company's social networking site in the PHP language development, in order to manage the code developed by PHP programmers, the senior leaders asked to build SVN server version control. The first version of the social networking site is deployed on top of the LNMP platform, with an Nginx server and access to the backend's PHP server via the FASTCGI protocol. To keep your data safe,
Request to build MySQL database master-slave cluster.

The social networking site project contains the user's album feature, allows users to upload photos, upload photos need to use the share
Storage to store. There are many open source solutions available for shared storage, such as MFS, Fastdfs, and so on. Public
Implemented using the MFS Distributed File system, and the MFS is mounted in the relevant directory division of the PHP server to determine

Case implementation

According to the company's needs, the implementation process is broadly divided into the following steps

Deploy the SVN server, create an access account for the PHP Programmer's Repo directory, and notify the programmer to
To import the code

Deploy MySQL master-slave server, create database and table according to PHP Programmer's requirements

Deploying Nginx Servers

Use keepalived to make hot spare for Nginx server

Deploying a PHP Server

Deploy MFS to mount the MFS file system in the relevant directory of the front-end PHP server

Notifies the on-line deployer to be released on-line.

Ensure that database services, PHP services, Nginx Services are started sequentially, and notify testers to start testing,
Site maintenance personnel Check Nginx, PHP and database server is working properly.

This article will deploy SVN and LNMP Architecture SVN deployment (IP:192.168.100.101)

The SVN deployment is complete, and PHP programmers can install the client in Windows/linux and then import the code to deploy the LNMP architecture-nginx Server (ip:192.168.100.102)

Test

Browser access to Nginx virtual IP 192.168.100.200/index.php to see the PHP interface

Switch off the master server keepalived service access virtual IP still see the PHP interface
