Ubuntu Linux下apache基于域名的虚拟主机配置

最近在学习linux，今天在linux下配置了下虚拟主机，下面是步骤：
要配置的网站http://www.myweb.cn
虚拟主机文件 myweb
1、首先在 /etc/apache2/sites-available 目录下新建一个空的虚拟主机文件myweb

cd /etc/apache2/sites-available 
touch myweb 

2、退出返回到apache2目录，在sites-enabled下创建myweb的软连接

cd /etc/apache2/sites-enabled 
ln -f -s ../sites-available/myweb myweb 

3、用vi打开myweb,进行配置如下：

<VirtualHost *:80>  
    ServerName www.myweb.cn 
    ServerAlias myweb.cn *.myweb.cn  
    ServerAdmin [e-mail]  
  
    DocumentRoot /var/www/myweb/  
    <Directory />  
        Options FollowSymLinks  
        AllowOverride None  
    </Directory>  
    <Directory /var/www/myweb/>  
        Options Indexes FollowSymLinks MultiViews  
        AllowOverride None  
        Order allow,deny  
        allow from all  
        # This directive allows us to have apache2's default start page  
        # in /apache2-default/, but still have / go to the right place  
        # Commented out for Ubuntu  
        #RedirectMatch ^/$ /apache2-default/  
    </Directory>  
  
    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/  
    <Directory "/usr/lib/cgi-bin">  
        AllowOverride None  
        Options ExecCGI -MultiViews +SymLinksIfOwnerMatch  
        Order allow,deny  
        Allow from all  
    </Directory>  
  
    ErrorLog /var/log/apache2/a.log  
  
    # Possible values include: debug, info, notice, warn, error, crit,  
    # alert, emerg.  
    LogLevel warn  
  
    CustomLog /var/log/apache2/access.log combined  
    ServerSignature On  
  
    Alias /doc/ "/usr/share/doc/"  
    <Directory "/usr/share/doc/">  
        Options Indexes MultiViews FollowSymLinks  
        AllowOverride None  
        Order deny,allow  
        Deny from all  
        Allow from 127.0.0.0/255.0.0.0 ::1/128  
    </Directory>  
</VirtualHost>  

4、执行a2ensite myweb 使虚拟主机生效,若要失效则为 a2dissite myweb

a2ensite myweb 

5、用restart重启或reload重载apache

/etc/init.d/apache2 reload 

6、修改host文件,加入127.0.0.1  http://www.myweb.cn

vi /etc/hosts 

现在网站就指向到/var/www/myweb文件夹中，可以在其中添加项目了
