为源码编译安装的httpd构建虚拟主机

1.  编辑/etc/httpd/httpd.conf文件
a.  注释掉默认的DocumentRoot "/usr/local/apache/htdocs"表示使用虚拟主机;
b.  启用Include /etc/httpd/extra/httpd-vhosts.conf虚拟主机选项;

2.  编辑/etc/httpd/extra/httpd-vhosts.conf文件
[root@www apache]# cd /etc/httpd/
[root@www httpd]# ll | grep extra
drwxr-xr-x  2 root root  4096 Aug 18 03:54 extra
Required modules: mod_log_config选项，此项要求使用mod_lod_config模块，那么需要编辑/etc/httpd/httpd.conf文件保证其中的
LoadModule log_config_module modules/mod_log_config.so是启用的;
虚拟主机信息为：
<VirtualHost *:80>
    ServerName />     DocumentRoot "/var/www/a" #默认是/usr/local/apache/docs下，我改为/var/www/
<Directory /var/www/a> #此配置段要加上，如果不加，就表示进制访问
        Options none
        AllowOverride none
        Require all granted     #允许所有人访问，此时不在是 Order  allow deny 
    </Directory>  allow from all
    ErrorLog "/var/log/httpd/a.error_log"
    CustomLog "/var/log/httpd/a.custom_log" common
</VirtualHost>
<VirtualHost *:80>
    ServerName />     DocumentRoot "/var/www/b"
<Directory /var/www/b>
        Options none
        AllowOverride none
        Require all granted
    </Directory>
    ErrorLog "/var/log/httpd/b.error_log" #错误日志和访问日志我改目录了，如果不改就是保存在/usr/local/apache/logs中
    CustomLog "/var/log/httpd/b.custom_log" common
然后创建各自的根目录
[root@www httpd]# mkdir /var/www/a
[root@www httpd]# mkdir /var/www/b
测试语法后重启服务
[root@www httpd]# httpd -t
Syntax OK
[root@www httpd]# service httpd restart
Stopping httpd: [  OK  ]
Starting httpd: [  OK  ]
为虚拟主机提供主页面
a.[root@www httpd]# vim /var/www/a/index.html
<h1>  works</h1>
b.[root@www httpd]# vim /var/www/b/index.html
<h1>  works</h1>
测试
[root@www extra]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.85.128   /> 192.168.85.128   /> [root@www httpd]# elinks --dump />                                 works
[root@www extra]# elinks --dump />                                 works
