How to Use the Screen Command in Linux

Screen is a terminal program in Linux which allows us to use a virtual (VT100 terminal) as full-screen window manager which multiplexes an open physical terminal between multiple processes, which are typically, interactive shells. It allows us to access multiple terminal sessions within a single terminal or a remote terminal session. It is most useful when addressing multiple Linux shell commands on the command line, as well as separating commands from the shell that started the commands.

Screen also allows a user to initiate a command from one terminal, disconnect from that terminal, and then reconnect from a different location to that same terminal, while using a different terminal without having to restart the command. This simply lets a user better control multiple and separate command windows.

Screen also lets multiple remote computers connect to the same screen session at once. This allows multiple users to connect to the same screen session allowing a second user to follow along with another administrator working on a server.

Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress.

Configuring SQL Server Always On Availability Groups on AWS EC2

In this article, we will review how to set up multi-subnet Always On Availability groups using AWS EC2 instances and AWS FSx as file share witness.

The following are the steps involved in creating a multi-subnet Always On Availability groups in AWS EC2 instances:

  • Prepare EC2 instances
  • Create AWS FSx for file share witness
  • Create Windows Server Failover cluster
  • Create Always On Availability Groups

Let’s go over these steps one by one.

Preparing EC2 instances

Log in to the AWS management console, click on Services, and navigate to the EC2 console.

EC2 Console

Click on the **Launch Instance **button and choose the instance of your choice. For demo purposes, I used Windows Server 2019 with SQL Server 2017 Enterprise edition image. You can also launch windows server image and install SQL Server by bringing your own license method (BYOL).

Instance for Always On Availability groups

Choose the instance type of your choice and configure the instance details like virtual private cloud network (VPC), subnet, etc. In this case, I am launching node 1 in the us-east-1a availability zone.

EC2 instance details

Add the storage and tag the instances. Configure the security group and launch the instance. Similarly, launch node 2 in the same virtual private cloud network (VPC) but a different availability zone i.e., us-east-1b. So, we have both the nodes up and running in the respective availability zones.

Ec2 instances in different zones

Add two secondary IPs for each node. One is used for Windows Server Failover Clustering, and the other will be used for Always On Availability group listener.

To add the secondary IPs, select the node, and click on Actions (1). Click on Networking (2) and finally select Manage IP Addresses (3).

Secondary IP address for EC2 instances

In Manage IP Addresses pop up, Click on Assign new IP two times and then click on Yes, Update as shown in the below image. You can input the custom IP addresses that are available or use the auto-assign option, which assigns a random IP address automatically.
