Host Apache Web Server

This article tells you how to download, install and configure Apache webserver on your Windows based computer to host a webpage. Go to www.apache.org and download the latest version of Apache's webserver. Apache was one of the first servers to support IP-based virtual hosts right out of the box. Versions 1.1 and later of Apache support both IP-based and name-based virtual hosts (vhosts). The latter variant of virtual hosts is sometimes also called host-based or non-IP virtual hosts. In general, it’s good to use the web server software that your web host uses. Unless you’re creating ASP.NET applications on Microsoft IIS, your host is likely to use Apache — the most widespread. The Apache HTTP Server, httpd, is an open source web server developed by the Apache Software Foundation. If you are upgrading from a previous release of Red Hat Enterprise Linux, you will need to update the httpd service configuration accordingly. This section reviews some of the newly added features, and guides you through the update of prior. By default Apache listens for incoming connections on port 80. For port-based virtual hosting, you need to tell Apache to listen for IP address 192.168.1.42 on port 80 and for IP address 192.168.1.43 on port 8080. To set up multiple ports, you need to edit the httpd.conf file.

Introduction

Virtual hosting is a method for hosting multiple websites on a single machine. There are two types of virtual hosting: Name-based virtual hosting and IP-based virtual hosting.IP-based virtual hosting is a technique to apply different directives based on the IP address and port a request is received on. You can assign a separate IP for each website on a single server using IP-based virtual hosting. This is mainly used to host different websites on different ports or IP addresses.

Requirements

A server running CentOS v. 7 with Apache installed
A desktop machine running Linux
A static IP address for each site you want to host.

Set up multiple IP addresses on a single network interface

To set up IP-based virtual hosting, you need to have more than one IP address assigned to your server. Setting up multiple IP addresses on a single network interface is called 'IP aliasing.' It is very useful, particularly if your server only has one network interface card (NIC).

To set up multiple IPs, you need to edit the ifcfg-eth0 file:

Add/edit the following lines:

Save and close the file when you are finished. Then restart the network service to make these changes take effect.

Set up multiple instances of Apache

By default Apache listens for incoming connections on port 80. For port-based virtual hosting, you need to tell Apache to listen for IP address 192.168.1.42 on port 80 and for IP address 192.168.1.43 on port 8080.

To set up multiple ports, you need to edit the httpd.conf file:

Add/edit the following lines:

Save and close the file, then restart Apache to make these changes take effect.

Create the directory structure

First, you need to make a directory structure which will hold the web pages. This directory is known as 'document root' for the domain.

In CentOS 7 the default Apache document root directory is /var/www/html/.

Now, create two directory for websites www.ip-vhost.com and www.port-vhost.com in the default Apache document root directory:

Create test web pages for each virtual host

Now, you need to create an index.html file for each website which will identify that specific domain.

Let's create an index.html file for the www.ip-vhost.com Nik collection 3 crack mac. ip virtual host.

Add the following content.

Save and close the file when you are finished.

Similarly, create an index.html file for the www.port-vhost.com virtual host.

Add the following content.

Save and close this file as well. Now, you have the pages to test the virtual host configuration.

Set up ownership and permissions

In CentOS 7 by default the Apache service runs as the user apache. You must change the ownership of these two virtual directories to apache, so that Apache can read and write data.

You should also make the Apache document root /var/www/html directory world readable, so that everyone can read files from that directory.

Now your web server has the permissions it needs to serve content.

Create virtual host files

The next step is to create a virtual host configuration file for each website. The name of each configuration file must end with .conf.

Let's create a virtual host file for website www.ip-vhost.com.

Add the following content.

Save and close the file when you are finished.

Similarly, create a virtual host file for website www.port-vhost.com.

Add the following content.

When you are finished, it is a good idea to check the syntax of the configuration. You can check the syntax of files with the following command:

After the syntax check is done, restart Apache to make these changes take effect.

Allow Apache through the firewall

Now, you need to allow the Apache port 80 and 8080 using FirewallD.

You can do this by running following commands:

Now, reload the firewall service for the changes to take effect.

Test the virtual hosts

Now on the desktop Linux computer, open your web browser and go to the URLs http://192.168.1.42:80 and http://192.168.1.43:8080.You should see sample pages that look like this:
