Most users should read about name based virtual hosts and IP based virtual hosts to decide which type they want to use, then learn more about name based or IP based virtual hosts, and then browse and order virtual hosting.

The newly created virtual host will have a default set of exchanges, but without other entities and user rights. For a user to connect and use the virtual host, permissions on it must be granted to every user who will be using the virtual host, for example using rabbitmqctl set_permissions.

To set up IP based virtual hosting, your server needs to be assigned multiple IP addresses. Configuring multiple IP addresses on a single network interface is called an IP alias. This is very useful, especially if your server has only one NIC, the NIC.

Now, when a request comes in, the server first checks to see if it is using the IP address that matches the NameVirtualHost. If so, it will look at each section with an IP address and try to find the one where the ServerName or ServerAlias ​​matches the requested hostname. If it finds it, it uses the configuration for the server. If no matching virtual host is found, then the first virtual host in the list corresponding to the IP address will be used.

If you need improved security features, more monitoring capabilities, more backup space, increased site reliability, or are planning to use any form of online payment, then you might want to consider using a VPS. With a VPS, you get reliable resources and count on top-notch security features.

Hardware and OS requirements for virtual hosting

Next, you need a host computer with specific hardware requirements. Specifications depend on the number of computers that you will run on that computer. As a general rule, it is recommended not to run more than 4 virtual machines on one computer to prevent slow performance. You may have IT support providers who provide virtualization services.

We recommend using different guest operating systems as each virtual machine requires its own unique software installation. For example, you might have one OS for Linux and another OS for Windows. This will be a useful approach for different clients who need to run different applications. In case their application does not support one specific OS, they can use another.

These instructions assume you are using the default CentOS location for the nginx virtual host, for example: /etc/nginx/conf.d and default docroot. For example: / usr / share / nginx / html, however you can change their locations to suit your environment.

For example, resource permissions in RabbitMQ are bound to a virtual host. The user has no global permissions, only permissions on one or more virtual hosts. Custom tags can be thought of as global permissions, but they are the exception to the rule.

Server availability under different names

Many servers want to be available under multiple names. This is possible with the ServerAlias ​​directive placed inside the section.

For example, in block 1, the ServerAlias ​​directive specifies that the names listed are other names that people can use to view the same site.

Virtual hosting based on name and IP address

Shared hosting based on names and IP addresses can be combined: a server can have multiple addresses and serve multiple names for some or all of the addresses. This method can be useful when using SSL and TLS with wildcard certificates.

For example, if the server operator had 2 certificates, one for * and one for *, the operator could serve and from the same IP, but for this would require a separate IP address for

Virtual hosting using Benefits. What is virtualization and why is it needed

The word private means exactly what it implies. Your virtual server is reserved for you, so you do not have to share RAM, CPU or data with other users.

With virtualization, you do not need to purchase a software license for each device separately. Instead, virtual licensing packages are available that are specifically designed for shared hosting servers. This results in competitive price reductions, which will have a significant impact on overall costs.

While it is true that a dedicated hosting package can solve many of the problems on this list. Keep in mind that a dedicated plan is the more expensive option. If you need to improve bandwidth, increase security or get more memory - the most affordable option is choosing a VPS hosting.

Before configuring shared hosting with Apache, the Apache Web software must be installed on the system. Otherwise, install using the default package installer called yum.

Since the VPS separates files from other users at the OS level, it is truly a private server. This means that your site is in a secure container with guaranteed server resources: memory, disk space, CPU cores, etc. You do not need to share this with others.

Now, suppose I have a server with a public IP address, a.a.a.a. I have registered 2 domain names: and Both of these two domain names point to the same IP address, i.e. This way, when a user types or in their web browser, the DNS server will point them to the IP address a.a.a.a.

The next step is to create a block for each individual host that you want to serve. The argument to the directive must be the same as the argument to the NameVirtualHost directive, that is, the IP address or * for all addresses. Within each block, you will need at least a ServerName directive to specify which host is being served and a DocumentRoot directive. This is to show you where the contents of the host are on the filesystem.

Comparison of shared and shared hosting. What are the benefits?

Shared hosting is the most common form of web hosting that works well for many new website owners. When you buy a shared hosting plan, you are sharing key resources: CPU, RAM, hard drive space with other site owners using that server.

When you upgrade to a virtual computer, it means you no longer need to spend money on physical devices. Up to four virtual servers can be connected to one physical server, which means that the total number of physical servers will be dramatically reduced. As a result, this will significantly reduce your costs, which you can use in other important areas of your business. In addition, the need for maintenance and costs also disappear when you have few physical servers at all.

All hosting provider plans are fully managed. This means you can stop worrying about the smallest technical details and focus on what really matters: creating great content for your website. However, if you need root access, consider choosing a shared hosting. Shared hosting is not intended for sites that use a lot of RAM. As your site grows and you add more and more content, you will begin to notice a decrease in your load time website. Once this happens, it is a sign that you have reached your limits. Upgrading to a VPS will allow you to scale your site without worrying about slow loading.

If you are running on a shared server, you will only be frustrated when you find out that advanced actions are not allowed or that applications do not have the support they need to work properly. Instead of tackling a potential problem, go for a VPS hosting and have more control over your actions!
