Apache| Server | Advanced III, Virtual Host (VM) settings
As a system administrator, if you have only one IP address, but there are several domain names, but also require access to each domain name to see different content, then how to do? There is no one server for each domain. This will take the virtual host technology, and fortunately Apache supports this functionality. There are two ways to have a virtual host: ip-based (ip-based), name-based (based on domain name). Ip-based refers to a domain name corresponding to an IP address, and name-based refers to multiple domain names corresponding to an IP address.
The setup of the virtual host is not complex, just add the appropriate command to the httpd.conf file.
The following is an example of a name-based (httpd.conf) virtual host (Editor's note: For space reasons, we only give the relevant part, the full text see www.swm.com.cn). IP: 192.168.188.20, two domain names are long.com.cn, short.com.cn respectively.
The Namevirtualhost command specifies on which IP to set the virtual host
Make specific settings for each host in the VirtualHost command.
The serveradmin command is to set the e-mail sent to the browser when the WWW server executes a problem, so that the user can contact the system administrator with the e-mail serveradmin.
The servername command is to set the WWW server's domain name.
Iv. provide personal homepage space, user homepage settings
Often see some websites to provide personal homepage, look very proud, in fact, you can also open the space on your machine to others, which is very simple to achieve. As long as you follow the instructions below to modify your WWW server configuration file.
To open the user's home page space, one is to determine the user's home page directory, the second is the Open User home page directory Read permissions.
Method One
You as root to user Chen open an account, the system will automatically give Chen allocated a space/home/user, and then in the/home/chen directory to build a public_html subdirectory, subdirectory properties to set to other readable and executable.
Then modify the access.conf. At the end of the file, add the following paragraph:
AllowOverride None
Order Allow,deny
Allow from all
Then, rerun httpd, the user can visit Chen's personal homepage via http://www.swm.com.cn/~chen/.
The advantage of this method is convenience, the disadvantage is that the security is too poor.
Method Two
Another option is to build a directory for users Chen in the/home/httpd directory Chen. Modify the Userdir in srm.conf to/home/httpd/*/html, then rerun httpd.
