前言

本文將詳細記錄一下如何在單臺服務器上，利用apache的virtualhost(虛擬主機)來搭建多個不同的web站點，并且每個站點獨立管理自己的session，下面話不多說了，來一起看看詳細的介紹吧。

開發環境

先說下我各項開發環境參數：

修改Apache配置

apache2.2 的配置文件路徑在 /etc/httpd/conf/httpd.conf

我們用下面的命令修改apache的配置文件：

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

添加監聽端口

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

默認的話，應該只會監聽80端口，這里我們在后面加上用于另外站點的端口號。例如我們A站點是默認的80端口，B站點計劃搭建在8080端口上，最終的配置文件修改成

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

啟動并添加VirtualHost

接著在配置文件中找到下面的章節：

### 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

上面的代碼是我已經修改好的，默認的話，最后兩行NameVirtualHost應該也是被注釋掉了。 因為我們要啟用虛擬主機，所以這里就把我們之前監聽的兩個端口都設置好。

同時，將之后的配置文件修改成如下的樣子，我們先來設置默認的80端口的站點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>

默認的Apache是沒有開啟VirtualHost的，所以這些代碼都是被注釋掉了的，我們這里只需要把DocumentRoot和ServerName所在的行去掉注釋并且編輯下就好了。

DocumentRoot指的的是我們A站點的網站根目錄位置

接下來再補充上8080端口的B站點信息就好了。

<VirtualHost *:8080> DocumentRoot /var/www/webB ServerName webB</VirtualHost>
