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。
基于端口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 |
[[email protected]119 extra]# mkdir /var/html/{blog,bbs} -p
[[email protected]-119 extra]# touch /var/html/{blog,bbs}/index.html
[[email protected]-119 extra]# tree /var/html/
/var/html/
├── bbs
│ └── index.html
└── blog
└── index.html
2 directories, 2 files
[[email protected]-119 extra]# for name in blog bbs;do echo "http://$name.bqh123.com" >/var/html/$name/index.html;done
[[email protected]-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
[[email protected]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：
[[email protected]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 [[email protected]-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：
[[email protected]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：
[[email protected]119 conf]# vim httpd.conf [[email protected]-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 [[email protected]-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：
[[email protected]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 [[email protected]-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 [[email protected]119 conf]# netstat -lntup|egrep "80|90" tcp 0 0 :::80 :::* LISTEN 1343/httpd tcp 0 0 :::90 :::* LISTEN 1343/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。
ok，Apache基于端口的虚拟主机配置及测试完成。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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：
④用cur或客户端浏览器测试一下：
ok，Apache基于IP的虚拟主机配置及测试完成
