单台服务器中利用Apache的VirtualHost如何搭建多个Web站点详解

前言

本文将详细记录一下如何在单台服务器上，利用apache的virtualhost(虚拟主机)来搭建多个不同的web站点，并且每个站点独立管理自己的session，下面话不多说了，来一起看看详细的介绍吧。

开发环境

先说下我各项开发环境参数：

修改Apache配置

apache2.2 的配置文件路径在 /etc/httpd/conf/httpd.conf

我们用下面的命令修改apache的配置文件：

$ vim /etc/httpd/conf/httpd.conf

添加监听端口

找到如下的部分，

## Listen: Allows you to bind Apache to specific IP addresses and/or# ports, in addition to the default. See also the <VirtualHost># directive.## Change this to Listen on specific IP addresses as shown below to# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)##Listen 12.34.56.78:80Listen 80

默认的话，应该只会监听80端口，这里我们在后面加上用于另外站点的端口号。例如我们A站点是默认的80端口，B站点计划搭建在8080端口上，最终的配置文件修改成

...#Listen 12.34.56.78:80Listen 80Listen 8080

启动并添加VirtualHost

接着在配置文件中找到下面的章节：

### Section 3: Virtual Hosts## VirtualHost: If you want to maintain multiple domains/hostnames on your# machine you can setup VirtualHost containers for them. Most configurations# use only name-based virtual hosts so the server doesn't need to worry about# IP addresses. This is indicated by the asterisks in the directives below.## Please see the documentation at# <URL:http://httpd.apache.org/docs/2.2/vhosts/># for further details before you try to setup virtual hosts.## You may use the command line option '-S' to verify your virtual host# configuration.## Use name-based virtual hosting.# NameVirtualHost *:80 NameVirtualHost *:8080

上面的代码是我已经修改好的，默认的话，最后两行NameVirtualHost应该也是被注释掉了。 因为我们要启用虚拟主机，所以这里就把我们之前监听的两个端口都设置好。

同时，将之后的配置文件修改成如下的样子，我们先来设置默认的80端口的站点A

## VirtualHost example:# Almost any Apache directive may go into a VirtualHost container.# The first VirtualHost section is used for requests without a known# server name.#<VirtualHost *:80># ServerAdmin webmaster@dummy-host.example.com DocumentRoot /var/www/webA ServerName webA# ErrorLog logs/dummy-host.example.com-error_log# CustomLog logs/dummy-host.example.com-access_log common</VirtualHost>
