ubuntu 下 apache 服务器虚拟主机的配置

【摘要】在阿里云购买了一个服务器（Linux ubuntu），有两个域名：www.mafuitan.net 和 blog.mafutian.net 这两个，此时先将这两个域名在阿里云服务器中添加域名的解析。然后在服务器的 apache 配置文件下面做一些修改。

需要修改的配置文件是：

1. vi /etc/apache2/sites-available/000-default

原本的内容如下：

1. <VirtualHost *:80>

2.         # The ServerName directive sets the request scheme, hostname and port that

3.         # the server uses to identify itself. This is used when creating

4.         # redirection URLs. In the context of virtual hosts, the ServerName

5.         # specifies what hostname must appear in the request's Host: header to

6.         # match this virtual host. For the default virtual host (this file) this

7.         # value is not decisive as it is used as a last resort host regardless.

8.         # However, you must set it for any further virtual host explicitly.

9.         #ServerName www.example.com

11.         ServerName www.mafutian.net

12.         ServerAlias www.mafutian.net

13.         DocumentRoot /var/www/mafutian

15.         # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,

16.         # error, crit, alert, emerg.

17.         # It is also possible to configure the loglevel for particular

18.         # modules, e.g.

19.         #LogLevel info ssl:warn

21.         ErrorLog ${APACHE_LOG_DIR}/error.log

22.         CustomLog ${APACHE_LOG_DIR}/access.log combined

24.         # For most configuration files from conf-available/, which are

25.         # enabled or disabled at a global level, it is possible to

26.         # include a line for only one particular virtual host. For example the

27.         # following line enables the CGI configuration for this host only

28.         # after it has been globally disabled with "a2disconf".

29.         #Include conf-available/serve-cgi-bin.conf

30. </VirtualHost>

修改为如下：

1. <VirtualHost *:80>

2.         DocumentRoot "/var/www/www"

3.         ServerName www.mafuitan.net

4.         ServerAlias www.mafutian.net

6.         <Directory "/var/www/www">

7.                 Options FollowSymLinks Indexes

8.                 AllowOverride All

9.                 Order deny,allow

10.                 Allow from all

11.                 Require all granted

12.         </Directory>

13. </VirtualHost>

14. <VirtualHost *:80>

15.         DocumentRoot "/var/www/blog"

16.         ServerName blog.mafutian.net

17.         ServerAlias blog.mafutian.net

19.         <Directory "/var/www/blog">

20.                 Options FollowSymLinks Indexes

21.                 AllowOverride All

22.                 Order deny,allow

23.                 Allow from all

24.                 Require all granted

25.         </Directory>

26. </VirtualHost>

重启 Apache 服务器：

1. service apache2 restart

另外可能需要修改目录 /var/www/blog 的权限，将这个目录下面的所有文件及子目录的权限设为 777：

1. chmod -R 777 /var/www/blog

然后访问：http://www.mafutian.net 访问的是服务器的 /var/www/www 这个目录

访问：http://blog.mafutian.net 访问的是服务器的 /var/www/blog 这是目录

（注意：不需要修改 hosts 文件）
