LNMP源码编译安装之PHP

q528

　　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 ~]# 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
　　检查php所需的；lib库

[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
　　再次确认基础库和扩展库程序是否安装齐全

[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
　　要一步一检查

• php安装*
  http://mirrors.sohu.com/php/
  
• php安装参数*

　　[root@web01 php-5.5.32]# ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/
[root@web01 php-5.5.32]# touch ext/phar/phar.phar
编译
[root@web01 php-5.5.32]#make && make install

　　[root@web01 php-5.5.32]# ln -s /application/php5.5.32/ /application/php
