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>
默认的Apache是没有开启VirtualHost的,所以这些代码都是被注释掉了的,我们这里只需要把DocumentRoot和ServerName所在的行去掉注释并且编辑下就好了。
DocumentRoot指的的是我们A站点的网站根目录位置
接下来再补充上8080端口的B站点信息就好了。
<VirtualHost *:8080> DocumentRoot /var/www/webB ServerName webB</VirtualHost>
