Deploy social networking site 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 the LNMP platform, with Nginx at the front and access to the backend's PHP server via the FASTCGI protocol. In order to ensure data security, MySQL database is required to build a master-slave cluster.

Social networking sites include users ' photo albums, allow users to upload photos, and upload photos that need to be stored using shared storage. The company decided to use the MFS Distributed file system and to mount the MFS to the relevant directory of the PHP server.

Case Environment

Case Environment requirements See table below

Host Operating System IP Address main software
Nginx CentOS 7 x86_64 Nginx
Php CentOS 7 x86_64 Php
MySQL Master CentOS 7 x86_64 mysql-5.5.24
MySQL Slave CentOS 7 x86_64 mysql-5.5.24
Svn CentOS 7 x86_64 Subversion
Build LNMP server to deploy Nginx server

First install the environment package, the dependency package.

  [[email protected] opt]# yum-y install pcre-devel zlib-devel[[email protected] opt]# useradd-m-S /sbin/nologin nginx #添加管理nginx的用户和组 [[email protected] mnt]# tar xf nginx-1.6.0.tar.gz-c/opt/#将软件包解压到指定目录 [[EMA               Il protected] opt]# cd nginx-1.6.0/#到解压目录中 [[email protected] nginx-1.6.0]#./configure \                                           #开始配置 >--prefix=/usr/local/nginx \ #指定安装目录 >--user=nginx \ #指定管理用户 >--group=nginx \ #指定管理组 >--with-http_st Ub_status_module #开启stub_status状态统计模块 [[email protected] nginx-1.6.0]# make && make Install #开始编译和安装 [[email protected] nginx-1.6.0]# ln-s/USR/LOCAL/NGINX/SBIN/NGINX/USR/LOCAL/SBIN/[[EMAIL&NB Sp;protected] nginx-1.6.0]# Nginx #开启nginx服务 # Establish a soft link to enable the system to identify the Nginx command  

Visit on the host to see if the access was successful.

Modify Nginx Configuration

The fastcgi access interface in the Nginx configuration file needs to be modified in order to access the PHP page.

[[email protected] nginx-1.6.0]# vim /usr/local/nginx/conf/nginx.conf        location ~ \.php$ {            root           /var/www/html/webphp;   #指定PHP服务器站点家目录            fastcgi_pass;    #指定PHP服务器地址及端口            fastcgi_index  index.php;            include        fastcgi.conf;        }

Restart Nginx Service

Deploying a PHP Server

Install PHP and accept nginx requests by configuring the PHP-FPM process to listen on port 9000. Install the environment pack and the dependent packages first.

[[email protected] ~]# yum -y install > gd > libxml2-devel > libjpeg-devel > libpng-devel > zlib-devel > fontconfig-devel > openssl-devel > bzip2-devel

Add PHP Admin Process user

useradd -M -s /sbin/nologin php

Extract the php-5.4.5 package to the specified directory.

[[email protected] mnt]# tar xf php-5.4.5.tar.bz2 -C /opt/

Switch to the php-5.4.5 unpacking directory and configure it.

[[email protected] mnt]# cd /opt/php-5.4.5./configure --prefix=/usr/local/php5 \                    #指定安装路径--with-gd #打开gd库的支持--with-zlib #开启zlib库的支持--with-config-file-path=/usr/local/php5 #指定php配置文件所在路径--enable-mbstring #多字节,字符串的支持--with-jpeg-dir #开启对jpeg图片的支持--with-openssl #openssl的支持,加密传输会用到--disable-ipv6 #关闭ipv6功能--with-mysql #最后几项都是让php支持mysql模块--with-mysqli --with-pdo-mysq --enable-fpm#启用fpm进程[[email protected] php-5.4.5]# make      #进行编译

However, an error occurred during the compilation process, such as finding a solution after the study.

/opt/php-5.4.5/ext/dom/node.c: 在函数‘dom_canonicalization’中:/opt/php-5.4.5/ext/dom/node.c:1898:21: 错误:提领指向不完全类型的指针

Here's the workaround, you need to hit a patch package.

[[email protected] opt]# curl -o php-5.2.17.patch下载patch包[[email protected] opt]# lsphp-5.2.17.patch  php-5.4.5  rh[[email protected] opt]# cd php-5.4.5/[[email protected] php-5.4.5]# patch -p0 -b <../php-5.2.17.patch  #将patch导入到php软件包中。patching file ext/dom/node.cpatching file ext/dom/documenttype.cpatching file ext/simplexml/simplexml.c#显示导入成功[[email protected] php-5.4.5]# make && make install #重新编译和安装

After the compilation installation is successful, start modifying the configuration file and making some optimizations.

[[email protected] php-5.4.5]# cp php.ini-development /usr/local/php5/php.ini#将配置文件模版复制出来[[email protected] php-5.4.5]# ln -s /usr/local/php5/bin/* /usr/local/bin/[[email protected] php-5.4.5]# ln -s /usr/local/php5/sbin/* /usr/local/sbin/#以上两项都是让系统能够识别php相关命令

Install the Accelerator for PHP.

Configure the PHP recognition accelerator.

[[email protected] php-5.3.x]# vim /usr/local/php5/php.ini[Zend Guard Loader]zend_extension=/usr/local/php5/lib/php/ZendGuardLoader.sozend_loader.enable=1#将这段话加入到php.ini配置文件中

Open Nginx's php-fpm support.

[[email protected] php-5.3.x]# cd /usr/local/php5/etc/[[email protected] etc]# cp  php-fpm.conf.default php-fpm.conf[[email protected] etc]# vim php-fpm.conf  #修改配置文件的相关参数pid = run/php-fpm.piduser = phpgroup = phppm.max_children=50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35listen =监听端口修改下,监听所有ip,如果只是127.0.0.1,那么php服务器无法监听到nginx服务器

Start the PHP-FPM process and see Port 9000 open.

[[email protected] etc]# /usr/local/sbin/php-fpm[[email protected] etc]# netstat -ntap | grep 9000    #9000端口已经开启tcp        0      0  *               LISTEN      

Just now in the Nginx configuration file, we configure the PHP server site, we need to create a site directory that is index.php.

[[email protected] etc]# mkdir -p /var/www/html/webphp#创建站点目录[[email protected] etc]# cd /var/www/html/webphp/[[email protected] webphp]# echo "123">index.php#创建站点首页

Test, Access, you can see the PHP site home page.

Deploying a MySQL Server

Install MySQL dependency packages and environment packs.

[[email protected] ~]# yum -y install ncurses-devel cmake#ncurses是字符终端下屏幕控制的基本库

Unzip the package to the specified directory and configure

[[email protected] ~]# cd /mnt/[[email protected] mnt]# tar xf mysql-5.5.24.tar.gz -C /opt/[[email protected] mnt]# cd /opt/mysql-5.5.24/[[email protected] mysql-5.5.24]# cmake  > -DCMAKE_INSTALL_PREFIX=/usr/local/mysql > -DDEFAULT_CHARSET=utf8 > -DDEFAULT_COLLATION=utf8_general_ci > -DWITH_EXTRA_CHARSETS=all > -DSYSCONFDIR=/etc > -DMYSQL_DATADIR=/home/mysql/ > -DMYSQL_UNIX_ADDR=/home/mysql/mysql.sock > -DWITH_MYISAM_STORAGE_ENGINE=1 > -DWITH_INNOBASE_STORAGE_ENGINE=1 > -DWITH_ARCHIVE_STORAGE_ENGINE=1 > -DWITH_BLACKHOLE_STORAGE_ENGINE=1 > -DENABLED_LOCAL_INFILE=1 > -DWITH_SSL=system > -DMYSQL_TCP_PORT=3306 > -DENABLE_DOWNLOADS=1 > -DWITH_SSL=bundled[[email protected] mysql-5.5.24]# make && make install#编译后安装

After the compilation is installed, the optimization is done.

[[email protected] mysql-5.5.24]# cp support-files/my-medium.cnf /etc/my.cnf#复制配置文件到/etc中cp:是否覆盖"/etc/my.cnf"? y[[email protected] mysql-5.5.24]# cp support-files/mysql.server /etc/init.d/mysqld#方便mysqld被service服务管理[[email protected] mysql-5.5.24]# echo "PATH=$PATH:/usr/local/mysql/bin/" >> /etc/profile#更改环境变量[[email protected] mysql-5.5.24]# source /etc/profile#使环境变量文件刷新生效[[email protected] mysql-5.5.24]# useradd -s /sbin/nologin mysql#添加mysql服务用户[[email protected] mysql-5.5.24]# chown -R mysql.mysql /usr/local/mysql#更改主文件夹的属主和属组

Initialize MySQL.

To create a soft link to a Mysql.sock file

[[email protected] mysql-5.5.24]# ln -s /var/lib/mysql/mysql.sock  /home/mysql/mysql.sock

Modify the MySQL startup script file.

[[email protected] mysql-5.5.24]# vim /etc/init.d/mysqldbasedir=/usr/local/mysqldatadir=/home/mysql[[email protected] mysql-5.5.24]# chmod +x /etc/init.d/mysqld [[email protected] mysql-5.5.24]# service mysqld startStarting MySQL..

Create the root user for MySQL.

Deploy MySQL master-slave database

Modify the MySQL master server ( configuration file.

[[email protected] mysql-5.5.24]# Vim/etc/my.cnfserver-id = 11#server-id master server cannot be the same log-bin=master-bin #主服务器日志文件log-slave-updates=true #从服务器更新二进制日志 [[email protected] mysql-5.5.24]# Servi Ce mysqld restartshutting down MySQL. success!

Modify MySQL from server configuration file

[[email protected] ~]# vim /etc/my.cnfserver-id = 12relay-log=relay-log-binrelay-log-index=slave-relay-bin.index[[email protected] ~]# service mysqld restart ERROR!

You can see the master-slave synchronization is successful, do a validation on the primary database to create a friend database, and also automatically generated from the database.
