目标：

  1. 建立DNS服务器，同时为linux.com, php.net, apache.org三个域提供解析；要求，每个域内的www主机均指向本机唯一的IP；
  2. 建立httpd服务器，分别为www.linux.com, www.php.net, www.apache.org 各提供一个虚拟主机，位置分别为/www/linux,/www/php,/www/apache；
  3. 每个虚拟主机的要使用各自的错误日志和访问日志，日志文件名称以虚拟主机名称打头；三个虚拟主机的日志文件都位于/www/logs目录中；
  4. www.linux.com虚拟主机仅允许来自172.16.0.0/16（除了172.16.100.0/24）的主机访问，且支持基于SSL的访问；
  5. www.php.net虚拟主机仅允许提供了帐号和密码的请求者访问；
  6. 通过http://www.apache/mail可以访问/web/mail目录中的网页，而且此目录允许执行CGI脚本(请测试通过)

我们开始吧！我的环境是redhat 5.8，已安装自带的bind97,bind97_lib,bind97_utils,httpd2.2.3，

1.建立DNS服务器。建立/etc/named.conf,并为之建立各自区域文件,启动named服务,测试，并把测试机（我用的是我的xp）的DNS改为刚建立的DNS的地址

   1:  /etc/named.conf :
   2:   
   3:  options {
   4:          directory "/var/named";
   5:  };
   6:  zone "linux.com" IN {
   7:          type master;
   8:          file "linux.php.apache";
   9:  };
  10:  zone "php.net" IN {
  11:          type master;
  12:          file "linux.php.apache";
  13:  };
  14:  zone "apache.org" IN {
  15:          type master;
  16:          file "linux.php.apache";
  17:  };
  18:   
  19:  /var/named/linux.php.apache
  20:   
  21:   
  22:  $TTL 86400
  23:  @               IN      SOA     ns      admin   (   
  24:                                          001 
  25:                                          2H  
  26:                                          5M  
  27:                                          7D  
  28:                                          2H )
  29:                  IN      NS      ns  
  30:  ns              IN      A       172.16.1.1
  31:  www             IN      A       172.16.1.1
 
 

2.修改/etc/httpd/conf/httpd.conf,注释主服务器区域的文档目录栏，取消基于域名的虚拟主机选项，然后建立虚拟机主机.新建几个目录，与日志文件，更改权限

   1:  #DocumentRoot "/var/www/html"　　　　　 ##282行左右
   2:  NameVirtualHost *:80　　　　　　　　　　##973行左右取消注释
   3:  ##在最后建立三个虚拟主机
   4:  <VirtualHost *:80>
   5:          ServerName "www.linux.com"
   6:          DocumentRoot /www/linux
   7:          ErrorLog /www/logs/linux-error_log
   8:          CustomLog /www/logs/linux-access_log common
   9:  </VirtualHost>
  10:  <VirtualHost *:80>
  11:          ServerName "www.php.net"
  12:          DocumentRoot /www/php
  13:          ErrorLog /www/logs/php-error_log
  14:          CustomLog /www/logs/php-access_log common
  15:  </VirtualHost>
  16:  <VirtualHost *:80>
  17:          ServerName "www.apache.org"
  18:          DocumentRoot /www/apache
  19:          ErrorLog /www/logs/apache-error_log
  20:          CustomLog /www/logs/apache-access_log common
  21:  </VirtualHost>
  22:   
  23:  mkdir /www/{linux,php,apache/logs}; ##建立目录
  24:  touch /www/logs/{linux-error_log,linux-access_log,php-error_log,php-access_log,apache-access_log,apache-error_log};
  25:  echo "I am linux " >/www/linux/index.html;
  26:  echo "I am php " >/www/php/index.html;
  27:  echo "I am linux " >/www/apache/index.html;
  28:  chown apache:apache -R /www

 

3.修改名字为www.linux.com虚拟主机的访问权限

   1:  <VirtualHost *:80>
   2:          ServerName "www.linux.com"
   3:          DocumentRoot /www/linux
   4:          ErrorLog /www/logs/linux-error_log
   5:          CustomLog /www/logs/linux-access_log common
   6:          <Directory "/www/linux">
   7:                  Order Allow,Deny
   8:                  Allow From 172.16.0.0/16
   9:                  Deny From 172.16.100.0/24
  10:          </Directory>
  11:  </VirtualHost>
4.为www.linux.com建立证书，方法见http://laoguang.blog.51cto.com/6013350/1035608
5.安装mod_ssl这个模块，基于ssl访问的https由它提供，修改它的配置文件/etc/httpd/conf.d/ssl.conf
   1:  yum -y install mod_ssl         ##已配好yum，自动安装
   2:   
   3:  /etc/httpd/conf.d/ssl.conf
   4:   
   5:  DocumentRoot "/www/linux"      　##86行加入这两行   
   6:  ServerName www.linux.com   
   7:  SSLCertificateFile /etc/httpd/conf.d/linux.crt        ##113行左右修改为SSL的证书的位置  (这是我建立证书的位置）   
   8:  SSLCertificateKeyFile /etc/httpd/conf.d/linux.key     ##120行左右修改为SSL的私钥的位置
6.为www.php.net 设定访问权限
   1:  <VirtualHost *:80>
   2:            ServerName "www.php.net"
   3:            DocumentRoot /www/php
   4:            ErrorLog /www/logs/php-error_log
   5:            CustomLog /www/logs/php-access_log common
   6:          <Directory /www/php>
   7:                  AllowOverride Authconfig
   8:                  options none
   9:                  Authtype basic
  10:                  Authname "Hi,I'm secreat"
  11:                  AuthUserFile /etc/httpd/conf.d/htpasswd
  12:                  Require valid-user
  13:          </Directory>
  14:    </VirtualHost>
 
7.生成密码文件
   1:  htpasswd -c -m /etc/httpd/conf.d/htpasswd laoguang
   2:  New password: 
   3:  Re-type new password: 
 
8.测试访问http://www.php.net 
9.修改虚拟主机www.apache.org的配置文件
   1:  <VirtualHost *:80>
   2:            ServerName "www.apache.org"
   3:            DocumentRoot /www/apache  
   4:            ErrorLog /www/logs/apache-error_log  
   5:            CustomLog /www/logs/apache-access_log common
   6:            alias /mail "/web/mail"
   7:            AddHandler cgi-script .cgi
   8:            <Directory /web/mail>
   9:                  Options execCGI
  10:            </Directory>
  11:    </VirtualHost>  
10.建立一个cgi文件测试
 
   1:  vim /www/apache/test.cgi
   2:   
   3:  #!/bin/bash
   4:  cat <<EOF
   5:  Content-Type: text/html
   6:   
   7:  <pre>
   8:  $(/bin/date)
   9:  my name is `id -nu`
  10:  my hostname $HOSTNAME
  11:  `/bin/date`
  12:  `echo $PATH`
  13:  </pre>
  14:  EOF
  15:   
  16:   
  17:  ##浏览器访问 www.apache.org/mail/test.cgi看是否能正常执行
 
OK到此，基本结束了，如果有不了解的欢迎留言。。。
