LNMP運行過程和解析原理

原理白話
用戶訪問NginxWeb服務器-Ngixn負責解析靜態數據（jpg,gif,css,js,avi,html）也接受動態數據(.php)動態數據通過FastCGI接口後拋（fastcgi_pass監聽 http://x.x.x.x:9000）給PHP服務器(php-fpm多個進程監聽9000端口)[進程配置文件php-fpm.conf設置進程數量]監聽到請求就會調用wrapper程序，wrapper會再啟多個線程調用PHP解析器（引擎）進行解析，如要連數據庫則向後數據庫（dbip，root.pass.port3306）進行請求.數據庫再將數據通過FastCGI將數據發給Nginx服務器後，Nginx再給用戶

確定nginx與數據庫是啟動的

[root@web01 ~]# netstat -tunlp|egrep "3306|80"
tcp        0      0 0.0.0.0:3306                0.0.0.0:*                   LISTEN      1657/mysqld         
tcp        0      0 0.0.0.0:80

檢查php所需的；lib庫

[root@web01 ~]# rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel 
libjpeg-turbo-devel-1.2.1-3.el6_5.x86_64
libpng-devel-1.2.49-2.el6_7.x86_64
freetype-devel-2.3.11-17.el6.x86_64
gd-devel-2.0.35-11.el6.x86_64
libcurl-devel-7.19.7-53.el6_9.x86_64
zlib-devel-1.2.3-29.el6.x86_64
libxml2-devel-2.7.6-21.el6_8.1.x86_64
 

更新bash源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
更新epel源
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

yum安裝lib庫及哈希程序

yum install -y  zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libmcrypt-devel 
yum install -y  mcrypt mhash
 

cd /home/oldboy/tools/
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar zxf libiconv-1.14.tar.gz
cd libiconv-1.14
./configure --prefix=/usr/local/libiconv

Centos7 下需要先操作如下

 cd  srclib/
sed -i -e ‘/gets is a security/d‘ ./stdio.in.h
|
make &&make install

再次確認基礎庫和擴展庫程序是否安裝齊全

[root@web01 tools]# rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libmcrypt-devel  mcrypt  mhash
libxslt-devel-1.1.26-2.el6_3.1.x86_64
mhash-0.9.9.9-3.el6.x86_64
libjpeg-turbo-devel-1.2.1-3.el6_5.x86_64
libmcrypt-devel-2.5.8-9.el6.x86_64
libpng-devel-1.2.49-2.el6_7.x86_64
freetype-devel-2.3.11-17.el6.x86_64
gd-devel-2.0.35-11.el6.x86_64
libcurl-devel-7.19.7-53.el6_9.x86_64
zlib-devel-1.2.3-29.el6.x86_64
libxml2-devel-2.7.6-21.el6_8.1.x86_64
mcrypt-2.6.8-10.el6.x86_64
