If you plan on hosting multiple domains on your server, you will need to configure virtual hosts on your Apache web server. When using the Apache web server, you can use virtual hosts similar to server blocks in Nginx to encapsulate configuration details and host more than one domain from a single server. While this works well for a single site, it can become unwieldy if you are hosting multiple sites.
Next, create a sample index. With your site directory and sample index file in place, you are almost ready to create the virtual host files. Virtual host files specify the configuration of your separate sites and tell the Apache web server how to respond to various domain requests. Before you create your virtual hosts, you will need to create a sites-available directory to store them in.
You will also create the sites-enabled directory that tells Apache that a virtual host is ready to serve to visitors. The sites-enabled directory will hold symbolic links to virtual hosts that we want to publish. Create both directories with the following command:. Next, you will tell Apache to look for virtual hosts in the sites-enabled directory. Save and close the file when you are done adding that line. Now that you have your virtual host directories in place, you will create your virtual host file.
This will tell Apache where to find the root directly that holds the publicly accessible web documents. It also tells Apache where to store error and request logs for this particular site. Now that you have created the virtual host files, you will enable them so that Apache knows to serve them to visitors.
To do this, create a symbolic link for each virtual host in the sites-enabled directory:. Your virtual host is now configured and ready to serve content.
SELinux is configured to work with the default Apache configuration. Since you set up a custom log directory in the virtual hosts configuration file, you will receive an error if you attempt to start the Apache service. To resolve this, you need to update the SELinux policies to allow Apache to write to the necessary files. SELinux brings heightened security to your CentOS 7 environment, therefore it is not recommended to completely disable the kernel module.
This step will cover two methods of adjusting Apache policies: universally and on a specific directory. Adjusting policies on directories is more secure, and is therefore the recommended approach.
While this approach is more convenient, it will not give you the same level of control as an approach that focuses on a file or directory policy. The setsebool command changes SELinux boolean values. The -P flag will update the boot-time value, making this change persist across reboots.
Since this option is not universally setting policies, you will need to manually set the context type for any new log directories specified in your virtual host configurations. Create the html directory for example. Next, create a sample index. With your site directory and sample index file in place, you are almost ready to create the virtual host files. Virtual host files specify the configuration of your separate sites and tell the Apache web server how to respond to various domain requests.
Before you create your virtual hosts, you will need to create a sites-available directory to store them in. You will also create the sites-enabled directory that tells Apache that a virtual host is ready to serve to visitors. The sites-enabled directory will hold symbolic links to virtual hosts that we want to publish.
Create both directories with the following command:. Next, you will tell Apache to look for virtual hosts in the sites-enabled directory. Press capital G to navigate towards the end of the file. Save and close the file when you are done adding that line.
Now that you have your virtual host directories in place, you will create your virtual host file. Add in the following configuration block, and change the example. This will tell Apache where to find the root directly that holds the publicly accessible web documents. It also tells Apache where to store error and request logs for this particular site.
Now that you have created the virtual host files, you will enable them so that Apache knows to serve them to visitors. To do this, create a symbolic link for each virtual host in the sites-enabled directory:. Your virtual host is now configured and ready to serve content. SELinux is a Linux kernel security module that brings heightened security for Linux systems. Since you changed the default configuration by setting up a custom log directory in the virtual hosts configuration file, you will receive an error if you attempt to start the Apache service.
To resolve this, you need to update the SELinux policies to allow Apache to write to the necessary files. This step will cover two methods of adjusting Apache policies: universally and on a specific directory. Adjusting policies on directories is more secure, and is therefore the recommended approach.

The -P flag will update the boot-time value, making this change persist across reboots. Since this option is not universally setting policies, you will need to manually set the context type for any new log directories specified in your virtual host configurations. This command lists and prints the SELinux context of the directory. You will receive output similar to the following:.
You can install previews and release candidates of. NET in one of the following ways:. When using a package manager to manage your installation of. NET, you may run into a conflict if you've previously installed a preview release.
The package manager may interpret the non-preview release as an earlier version of. To install the non-preview release, first uninstall the preview versions.
For more information about uninstalling. NET, see How to remove the. Before you install. NET, run the following commands to add the Microsoft package signing key to your list of trusted keys and add the Microsoft package repository.
Open a terminal and run the following commands:. If you install the. To install the. The ASP. NET Core Runtime allows you to run apps that were made with. NET that didn't provide the runtime. The following command installs the ASP. NET Core Runtime, which is the most compatible runtime for.
In your terminal, run the following command:. As an alternative to the ASP. NET Core Runtime, you can install the. NET Core support: replace aspnetcore-runtime The following command install the ASP. All versions of. You can try and use the package manager to install a different version of. However, the requested version may not be available.
This article will always give the instructions for the latest supported version. Valid options are any released version, such as:. For a list of supported distributions, see Install.
