What does "yum install httpd -y ami" do?

The command yum install httpd -y ami is used in Linux-based systems, particularly those using the YUM (Yellowdog Updater, Modified) package manager, to install the Apache HTTP Server. Let's break down each part:

1. yum:

- yum is the package manager used in many Red Hat-based Linux distributions like CentOS, Fedora, and Amazon Linux. It's used to install, update, and remove software packages.

2. install:

- This is a yum command that instructs the package manager to install one or more software packages.

3. httpd:

- httpd is the name of the package for the Apache HTTP Server. This is the software that allows a computer to host websites by serving web pages to requesting clients (browsers).

4. -y:

- The -y flag is used to automatically answer "yes" to any prompts that yum might present during the installation process. This means the user does not need to confirm the installation and any associated actions.

5. ami:

- The `ami` part of the command is likely incorrect or a typo, as `ami` is not a standard option or argument for the `yum install` command. It is most probably a mistake. If you run yum install httpd -y ami, it's likely the command will not work as expected and may throw an error because ami is not a valid package to be installed alongside httpd.

The Correct Command:

- The usual command to install the Apache HTTP server with automated confirmation using yum would be: yum install httpd -y

In Summary:

- The command yum install httpd -y will install the Apache HTTP server package on your system, and automatically confirm all installation prompts. However, the command yum install httpd -y ami is incorrect and will probably fail because ami is not a valid package name in this context.

Important Notes:

- After installing httpd, you will typically need to start the service to begin using it, this is commonly done by running sudo systemctl start httpd. You can also check its status by running sudo systemctl status httpd and also configure it to start on boot with sudo systemctl enable httpd.

- It's important to ensure that your system is updated (using yum update -y) before installing new packages to avoid compatibility issues.
