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-119 extra]# mkdir /var/html/{blog,bbs} -p
[root@bqh-119 extra]# touch /var/html/{blog,bbs}/index.html
[root@bqh-119 extra]# tree /var/html/
/var/html/
├── bbs
│   └── index.html
└── blog
    └── index.html

2 directories, 2 files
[root@bqh-119 extra]# for name in blog bbs;do echo "http://$name.bqh123.com" >/var/html/$name/index.html;done
[root@bqh-119 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-119 extra]# vim httpd-vhosts.conf

  1 #
  2 # Virtual Hosts
  3 #
  4 # If you want to maintain multiple domains/hostnames on your
  5 # machine you can setup VirtualHost containers for them. Most configurations
  6 # use only name-based virtual hosts so the server doesn't need to worry about
  7 # IP addresses. This is indicated by the asterisks in the directives below.
  8 #
  9 # Please see the documentation at 
 10 # <URL:http://httpd.apache.org/docs/2.2/vhosts/>
 11 # for further details before you try to setup virtual hosts.
 12 #
 13 # You may use the command line option '-S' to verify your virtual host
 14 # configuration.
 15 
 16 #
 17 # Use name-based virtual hosting.
 18 #
 19 NameVirtualHost *:80
 20 
 21 #
 22 # VirtualHost example:
 23 # Almost any Apache directive may go into a VirtualHost container.
 24 # The first VirtualHost section is used for all requests that do not
 25 # match a ServerName or ServerAlias in any <VirtualHost> block.
 26 #
 27 <VirtualHost *:80>
 28     ServerAdmin 1147076062@qq.com
 29     DocumentRoot "/var/html/blog"
 30     ServerName blog.bqh123.com
 31     ServerAlias bg.bqh123.com
 32     ErrorLog "logs/blog-error_log"
 33     CustomLog "logs/blog-access_log" common
 34 </VirtualHost>
 35 
 36 <VirtualHost *:80>
 37     ServerAdmin 1147076062@qq.com
 38     DocumentRoot "/var/html/bbs"
 39     ServerName bbs.bqh123.com
 40     ServerAlias bs.bqh123.com
 41     ErrorLog "logs/bbs-error_log"
 42     CustomLog "logs/bbs-access_log" common
 43 /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-119 extra]# ../../bin/apachectl -t
httpd: apr_sockaddr_info_get() failed for bqh-119
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
Syntax OK
[root@bqh-119 extra]# ../../bin/apachectl graceful
httpd: apr_sockaddr_info_get() failed for bqh-119
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-119 extra]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         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：

 17 <Directory "/var/html">
 18     Options  FollowSymLinks
 19     AllowOverride None
 20     Order allow,deny
 21     Allow from all
 22 </Directory>

检测配置文件语法错误，刷新配置，从新启动：

[root@bqh-119 conf]# vim httpd.conf
[root@bqh-119 conf]# ../bin/apachectl -t
httpd: apr_sockaddr_info_get() failed for bqh-119
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
Syntax OK
[root@bqh-119 conf]# ../bin/apachectl graceful
httpd: apr_sockaddr_info_get() failed for bqh-119
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-119 conf]# ../bin/apachectl -t
httpd: apr_sockaddr_info_get() failed for bqh-119
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
Syntax OK
[root@bqh-119 conf]# ../bin/apachectl graceful

httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[root@bqh-119 conf]# netstat -lntup|egrep "80|90"
