In this tutorial we will learn how to create VirtualHost in Apache Webserver.
I believe you have already installed the apache web server in CentOS or Red Hat.(How to install apache web server)
With the help of VirtualHost we can host many domains or website from single Web Server.
This is a simple example to start with your first VirtualHost configuration in Apache Webserver.
I have used a few terms which is required for setting up the basic VirtualHost configuration.
DocumentRoot : This is used to define the Data path of website.In this example it is at /var/www/html/example.com. You can give other data path also
ServerAdmin : The contact person email id, Here I have given [email protected] You can also give [email protected] or your own email id. Customize as per your requirement
ServerName : Fully Qualified domain Name of server ,use
hostname -f command to get FQDN of webserver. My server has FQDN as webserver.example.com
DirectoryIndex : This is webserver main page or index page. It can be any with suffix index and applicable file format like index.html,index.php etc
ErrorLog As the name suggest it is for keeping log of web server.Here we have give the path /var/log/httpd/error_log which is already bydefault present there. You can customize this path as per your requirement
CustomLog: Here we have customize our webserver logging and all output will be log in file called /var/log/httpd/access_log . You can see common logformat has been used.
