Apache基于域名、端口、IP的虚拟主机配置（Centos 6.5）

虚拟主机：部署多个站点，每个站点，希望用不同的域名和站点目录，或者是不同的端口，不同的ip，需要虚拟主机功能。一句话，一个http服务要配置多个站点，就需要虚拟主机。

虚拟主机分类：基于域名、基于端口、基于ip；所谓的基于**，就是靠**来区分不同的站点，支持各种混合，N多个虚拟主机。

基于域名的虚拟主机配置如下：

_{创建环境：}

站点目录	域名
/var/html/blog	blog.bqh123.com
/var/html/bbs	bbs.bqh123.com

[root@bqh- extra]# mkdir /var/html/{blog,bbs} -p
[root@bqh- extra]# touch /var/html/{blog,bbs}/index.html
[root@bqh- extra]# tree /var/html/
/var/html/
├── bbs
│   └── index.html
└── blog
    └── index.html

 directories,  files
[root@bqh- extra]# for name in blog bbs;do echo "http://$name.bqh123.com" >/var/html/$name/index.html;done
[root@bqh- extra]# for name in blog bbs;do  cat /var/html/$name/index.html;done
http://blog.bqh123.com
http://bbs.bqh123.com

配置虚拟主机配置文件：httpd-vhosts.conf

[root@bqh- extra]# vim httpd-vhosts.conf

   #
   # Virtual Hosts
   #
   # 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 *:

  #
  # VirtualHost example:
  # Almost any Apache directive may go into a VirtualHost container.
  # The first VirtualHost section is used for all requests that do not
  # match a ServerName or ServerAlias in any <VirtualHost> block.
  #
  <VirtualHost *:>
      ServerAdmin @qq.com
      DocumentRoot "/var/html/blog"
      ServerName blog.bqh123.com
      ServerAlias bg.bqh123.com
      ErrorLog "logs/blog-error_log"
      CustomLog "logs/blog-access_log" common
  </VirtualHost>

  <VirtualHost *:>
      ServerAdmin @qq.com
      DocumentRoot "/var/html/bbs"
      ServerName bbs.bqh123.com
      ServerAlias bs.bqh123.com
      ErrorLog "logs/bbs-error_log"
      CustomLog "logs/bbs-access_log" common
  /VirtualHost>

 在主配置文件（httpd.conf）里激活生效：

• Include conf/extra/httpd-vhosts.conf
• Include conf/extra/httpd-mpm.conf

检测配置文件语法错误并刷新配置：

[root@bqh- extra]# ../../bin/apachectl -t
httpd: apr_sockaddr_info_get() failed for bqh-
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
Syntax OK
[root@bqh- extra]# ../../bin/apachectl graceful
httpd: apr_sockaddr_info_get() failed for bqh-
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

配置一下hosts解析：

[root@bqh- extra]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.0.119 blog.bqh123.com bbs.bqh123.com

windows系统，在“C:\Windows\System32\drivers\etc”下的hosts中配置一下域名解析:

----------------------------------------------------------------------------------

用cur或客户端浏览器测试一下：

解决方法：

在主配置文件（httpd.conf）追加一下内容：

  <Directory "/var/html">
      Options  FollowSymLinks
      AllowOverride None
      Order allow,deny
      Allow from all
  </Directory>

检测配置文件语法错误，刷新配置，从新启动：

[root@bqh- conf]# vim httpd.conf
[root@bqh- conf]# ../bin/apachectl -t
httpd: apr_sockaddr_info_get() failed for bqh-
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
Syntax OK
[root@bqh- conf]# ../bin/apachectl graceful
httpd: apr_sockaddr_info_get() failed for bqh-
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

用cur或客户端浏览器测试一下：

ok，Apache基于域名的虚拟主机配置及测试完成。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

基于端口的虚拟主机配置如下：

①在主配置文件httpd.conf里配置监听新增端口：

②在虚拟机配置文件httpd-vhosts.conf修改如下：

③检测配置文件语法错误，刷新配置，从新启动：

[root@bqh- conf]# ../bin/apachectl -t
httpd: apr_sockaddr_info_get() failed for bqh-
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
Syntax OK
[root@bqh- conf]# ../bin/apachectl graceful
httpd: apr_sockaddr_info_get() failed for bqh-
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[root@bqh- conf]# netstat -lntup|egrep "80|90"
tcp               :::                       :::*                        LISTEN      /httpd
tcp               :::                       :::*                        LISTEN      /httpd 

④用cur或客户端浏览器测试一下：

注：如果不加端口访问，默认以ip的形式解析访问。

基于IP的虚拟主机配置如下：

①添加别名IP

②在虚拟机配置文件httpd-vhosts.conf修改如下：

③检测配置文件语法错误，刷新配置，从新启动：
