Additional Recommended Steps for New CentOS 7 Servers

Introduction

If you've just set up a new CentOS 7 server, there are a few additional steps you can take to ensure optimal security and functionality. In this tutorial, we'll walk you through the recommended steps.

Step 1: Update the System

The first step is to update the system to ensure that all the latest security patches and bug fixes are installed. To do this, simply run the following command:

yum update -y

This command will update all packages and dependencies to the latest versions.

Step 2: Configure Firewall

Next, you'll want to configure the firewall to ensure that your server is protected from unwanted traffic. CentOS 7 comes with the firewalld firewall by default, so you can use that to configure your firewall rules. Here's an example of how to allow incoming HTTP and HTTPS traffic:

				firewall-cmd --zone=public --add-service=http --permanent
				firewall-cmd --zone=public --add-service=https --permanent
				firewall-cmd --reload

This will allow incoming HTTP and HTTPS traffic through the firewall.

Step 3: Install Additional Packages

Depending on your needs, you may want to install additional packages on your CentOS 7 server. Here are a few examples:

  • vim: A text editor that's more powerful than the default nano.
  • git: A version control system that's widely used in software development.
  • htop: A process monitoring tool that's more powerful than the default top.

You can install these packages by running the following command:

yum install vim git htop -y

Conclusion

By following these additional recommended steps, you can ensure that your CentOS 7 server is secure and functional. Remember to keep your system up to date and configure your firewall to protect your server from unwanted traffic.
