LAMP架构实现网站动静分离及流行博客论坛安装实验

静分离能有效提升站点访问效率，此时apache工作在反向代理模式。PHP不在作为apache的模块。而是以独立服务器的方式运行。两者之间通过fcgi机制建立通讯。

一.安装DNS服务实现域名解析

1.安装bind

[root@www ~]# yum install bind

2.配置named主配置文件

[root@www ~]# vim /etc/named.conf

//

// named.conf

//

// Provided by Red Hat bind package toconfigure the ISC BIND named(8) DNS

// server as a caching only nameserver (asa localhost DNS resolver only).

//

// See /usr/share/doc/bind*/sample/ forexample named configuration files.

//

options {

//     listen-on port 53 { 127.0.0.1; };

//     listen-on-v6 port 53 { ::1; };

       directory      "/var/named";

       dump-file      "/var/named/data/cache_dump.db";

       statistics-file "/var/named/data/named_stats.txt";

       memstatistics-file "/var/named/data/named_mem_stats.txt";

//     allow-query    { localhost; };

       recursion yes;

//     dnssec-enable yes;

//     dnssec-validation yes;

//     dnssec-lookaside auto;

       /* Path to ISC DLV key */

       /*bindkeys-file "/etc/named.iscdlv.key";

       managed-keys-directory "/var/named/dynamic";

       */

};

logging {

       channel default_debug {

               file"data/named.run";

                severity dynamic;

       };

};

zone "." IN {

       type hint;

       file "named.ca";

};

include"/etc/named.rfc1912.zones";

include "/etc/named.root.key";

3.配置区域配置文件

4.配置区域解析库文件（正向）

更改权限及属主属组

5.检查语法

6.启动named服务

将本地网络的DNS服务器地址指向172.16.31.20

测试完全区域：

二.源码安装httpd-2.4.10

1.安装apr及apr-util

设置apr及apr-util成为系统环境变量

2.源码安装httpd

编译参数注释

--prefix=        #指定安装到/usr/local/apache路径下

--sysconfdir=    #指定配置文件安装到/etc/httpd24下

--enable=so      #支持动态装卸载模块

--enable-ssl    #支持https加密传输

--enable-rewrite #支持URL重写

--enable-cgi    #支持cgi格式脚本

--with-z         #支持zlib压缩

--with-pcre      #支持扩展正则表达式

--with-apr      #指定apr安装位置

--with-apr-util  #指定apr-util安装位置

--enable-mpms-shared  #把mpm三种模式以共享模块的方式编译进去

--enable-mpm    #httpd启动是默认是开启event模式

--enable-rewrite #支持反向代理

安装：

3.创建httpd服务脚本（因为系统已安装httpd，我们需要安装到其他路径，服务脚本也一样要更改名称，与原httpd服务区分）

[root@www httpd-2.4.10]# cp /etc/rc.d/init.d/httpd httpd24

[root@www httpd-2.4.10]# vim httpd24

#!/bin/bash

#

# httpd        Startup script for the Apache HTTPServer

#

#              server implementing the currentHTTP standards.

# processname: httpd

# config: /etc/httpd/conf/httpd.conf

# config: /etc/sysconfig/httpd

# pidfile: /var/run/httpd/httpd.pid

       killproc -p ${pidfile} -d ${STOP_TIMEOUT} $httpd

复制脚本到服务脚本存放路径：

[root@www httpd-2.4.10]# cp httpd24  /etc/rc.d/init.d/httpd24

将httpd24服务加入系统启动：

4.启动httpd24服务

查看服务监听端口：

测试：

 httpd-2.4.10安装完毕
