Virtual Host configuration process

So our path in this example is going to look like this
DocumentRoot: / home/jb51 / sites/demo ofstack. com
ServerName: demo. ofstack. com

1. Enter the apache virtual host setup directory 


cd /etc/apache2/sites-available

2. Create the file demo.ofstack.com 


<VirtualHost *:80> 
    ServerAdmin webmaster@localhost 
    DirectoryIndex index.html index.php 
    DocumentRoot /home/jb51 /sites/demo.ofstack.com 
    ServerName demo.ofstack.com 
    ServerAlias demo.ofstack.com 
    <Directory "/home/jb51 /sites/demo.ofstack.com"> 
        allow from all Options + Indexes 
    </Directory> 
</VirtualHost>


3. Activate the virtual host configuration 


sudo a2ensite demo.ofstack.com


4. Enter /etc/apache2/ sites-enabled/directory to view all the active virtual hosts. You can log off with sudo a2dissite demo.ofstack.com 


cd /etc/apache2/sites-enabled 
ls -lt

According to 



lrwxrwxrwx 1 root root 36 2013-04-05 17:29 demo.ofstack.com -> ../sites-available/demo.ofstack.com 


5. Restart the apache service 


sudo /etc/init.d/apache2 restart


6. host ubuntu Settings 


vim /etc/hosts 



127.0.0.1 demo.ofstack.com


7. < Directory > Set to enable.htaccess with display directory structure list 


<Directory "/home/jb51 /demo.ofstack.com"> 
AllowOverride none 
AllowOverride all 
Options -Indexes FollowSymLinks 
</Directory>

AllowOverride none means close.htaccess, if you want to open it, you can set AllowOverride all
Options-Indexes means close the directory structure display. If you want to turn it on, you can set it to Options Indexes
Options FollowSymLinks means support for symbol link (soft connection), which can be set to Options-FollowSymLinks if you want to close it
