How many virtual hosts can i have

If you are using actual domains or alternate values, swap out the highlighted text for these. Now we have the directory structure for our files, but they are owned by our root user. If we want our regular user to be able to modify files in our web directories, we can change the ownership by doing this:. We should also modify our permissions to ensure that read access is permitted to the general web directory and all of the files and folders it contains so that pages can be served correctly:.

Your web server should now have the permissions it needs to serve content, and your user should be able to create content within the necessary folders. We can open up an index. Within this file, create an HTML document that indicates the site it is connected to, like the following:. Save and close this file as well. You now have the pages necessary to test the virtual host configuration.

Virtual host files are the files that specify the actual configuration of our virtual hosts and dictate how the Apache web server will respond to various domain requests. Apache comes with a default virtual host file called default.

We are going to copy it over to create a virtual host file for each of our domains. We will start with one domain, configure it, copy it for our second domain, and then make the few further adjustments needed.

The default Ubuntu configuration requires that each virtual host file end in. Within this file, we will customize the items for our first domain and add some additional directives. This virtual host section matches any requests that are made on port 80, the default HTTP port. First, we need to change the ServerAdmin directive to an email that the site administrator can receive emails through.

After this, we need to add two directives. The first, called ServerName , establishes the base domain that should match for this virtual host definition. This will most likely be your domain. The second, called ServerAlias , defines further names that should match as if they were the base name. The server has two IP addresses In each case, we want to run hosts on ports 80 and Any address mentioned in the argument to a virtualhost that never appears in another virtual host is a strictly IP-based virtual host.

The following example allows a front-end machine to proxy a virtual host through to a server running on another machine. In the example, a virtual host of the same name is configured on a machine at The ProxyPreserveHost On directive is used so that the desired hostname is passed through, in case we are proxying multiple hostnames to a single machine. Catching every request to any unspecified IP address and port, i.

Using such a default vhost with a wildcard port effectively prevents any request going to the main server. You can use AliasMatch or RewriteRule to rewrite any request to a single information page or script. The default vhost for port 80 which must appear before any default vhost with a wildcard port catches all requests that were sent to an unspecified IP address. The main server is never used to serve a request.

A request to an unspecified address on port 80 is served from the default vhost. Any other request to an unspecified address and port is served from the main server. The name-based vhost with the hostname www. To avoid problems with name servers or proxies who cached the old IP address for the name-based vhost we want to provide both variants during a migration phase.

Quit and Save with :wq. Repeat this process for your domain2. Out of the box, your server is set to read the default default. But, in our previous step we made a new config file for each domain. So, we will need to disable the default file. We restart the Apache service to register our changes. After either one of these aspects are set, you'll be able to visit your website in a browser to see the index.

I would read over the Virtual Hosts Documentation.

If each virtual host has its own log, the limit is l ikely 64 due to file descriptor limits. However, you can configure Apache to run more using this guide. At our company we have about vhosts on a Plesk VPS.

In a nutshell, we create single product marketing websites for customers, where each website has it's own unique TLD. In itself this never triggered any issue for performance of Apache, but we did run into other challenges. Because we create about a new websites each day, Apache needs to restart very often to enable the newly added vhost files. To cover for this, we implemented a caching layer to prevent timeouts on the website each time the server restarts.
