一.FastCGI
快速通用网关接口(socket)，为HTTP服务器与其他机器上的程序服务通信交流工具常规web程序都支持。
LNMP运行过程和解析原理
原理白话用户访问NginxWeb服务器-Ngixn负责解析静态数据（jpg,gif,css,js,avi,html）也接受动态数据(.php)动态数据通过FastCGI接口后抛（fastcgi_pass监听 http://x.x.x.x:9000）给PHP服务器(php-fpm多个进程监听9000端口)[进程配置文件php-fpm.conf设置进程数量]监听到请求就会调用wrapper程序，wrapper会再启多个线程调用PHP解析器（引擎）进行解析，如要连数据库则向后数据库（dbip，root.pass.port3306）进行请求.数据库再将数据通过FastCGI将数据发给Nginx服务器后，Nginx再给用户
确定nginx与数据库是启动的

[root@web01 ~]# rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel

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安装lib库及哈希程序
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
