Centos Virtual hosting | Centos enabling multi apache hosting through 1 IP

OK, so now you decided to have one VPS, one IP, and many sites?
Cool, its very easy
First in the root folder, create your website folders, like you have 2 websites, so name them as site1.com and site2.com
So now you'll be having two website folders site1.com and site2.com in your root directory.

Now navigate to /etc/httpd/conf/ and start editing httpd.conf file,
At the end of the page, you will find a line, just like below
#NameVirtualHost *:80
Just uncomment that by removing # from it, So that it becomes like the below one:-

NameVirtualHost *:80

Then below their will be more lines which will be commented so uncomment them also, and make them look something like this


<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot /var/www/html/site1.com
    ServerName site1.com
    ErrorLog logs/site1-error_log
    CustomLog logs/site1-access_log common
</VirtualHost>
<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot /var/www/html/site2.com
    ServerName site2.com
    ErrorLog logs/site2-error_log
    CustomLog logs/site2-access_log common
</VirtualHost>

Thats it, after this just restart your apacheby the following command

service httpd restart

Done,
You have successfully enabled multi-site or virtual hosting on apache Centos.

How to enable mod_rewrite in centos via SSH


This is a very simple question, but for beginners it is little bit difficult,
Now assuming that everything is installed, open the httpd conf file and start editing it,

You can find this file in
/etc/httpd/conf/httpd.conf

or directly edit it
vi /etc/httpd/conf/httpd.conf

 in this file search for Directory "/var/www/html" this can be on line 290-320
You will find a line of code, just like below
AllowOveride None

Just change it to
AllowOverideAll

Save it, and exit, mod_rewrite is enabled on your server
