Thank you All! I've a surprise for you :)

Many thanks to all of my followers and those who have commented on my posts, and/or replied to my comments. It means a lot. Everyone is so kind, helpful and welcoming, making this blogging journey even more amazing! It's so awesome to see my hobby grow into something even more amazing, Thank you so so much! hope this blog continues to grow! ❤️

I received so many request to start writing on Linux from basic so that they can learn Linux. The topics I covered in previous posts were only helpful for more than a years experienced Linux Administrator but not for the those who are new on Linux and planning to learn Linux.

So on demand I am starting a series of posts and writing on Linux Administration but won't be able to give very much time on it due to some other priorities. I will try to post at least two posts in a week, requesting you to please practice and let me know if there are any issues/concerns.

If you do so I guarantee that at the end of series you will be very much comfortable on Linux like Windows and will be able to work on Linux based production servers.

For practice, I am planning to prepare a video and explain how to setup lab environment, so that you can practice easily on your current System only.

There are so many flavors of Linux available in Market but I'll use Red Hat Linux, which is also known as RHEL(Red Hat Enterprise Linux). We will use latest stable version RHEL7 which is 7.3. Why will I prefer RHEL? because-
1. Very much use in corporate
2. Global certification
If you want at the completion of series you can give Red Hat global certification exam and grab two certificates RHCSA and RHCE, and add the same in your CV that actually impress recruiters.

Thank you again..........

Failed to get D-Bus connection: Operation not permitted

" Failed to get D-Bus connection: Operation not permitted " - systemctl command is not working in Docker container. If systemctl command is not working in your container and giving subjected error message then simple solution of this error is, create container with -- privileged option and also provide init file full path  /usr/sbin/init [root@server109 ~]# docker container run -dit --privileged --name systemctl_not_working_centos1 centos:7 /usr/sbin/init For detailed explanation and understanding I am writing more about it, please have look below. If we have a daemon based program(httpd, sshd, jenkins, docker etc.) running inside a container and we would like to start/stop or check status of daemon inside docker then it becomes difficult for us to perform such operations , because by default systemctl and service  commands don't work inside docker. Normally we run below commands to check services status in Linux systems. [root@server109 ~]# systemctl status ...

AWS cloud automation using Terraform

In this post I'll create multiple resources in AWS cloud using Terraform . Terraform is an infrastructure as code( IAC ) software which can do lots of things but it is superb in cloud automation. To use Terraform we have write code in a high-level configuration language known as Hashicorp Configuration Language , optionally we can write code in JSON as well. I'll create below service using Terraform- 1. Create the key-pair and security group which allow inbound traffic on port 80 and 22 2. Launch EC2 instance. 3. To create EC2 instance use same key and security group which created in step 1 4. Launch Volume(EBS) and mount this volume into /var/www/html directory 5. Upload index.php file and an image on GitHub repository 6. Clone GitHub repository into /var/www/html 7. Create S3 bucket, copy images from GitHub repo into it and set permission to public readable 8 Create a CloudFront use S3 bucket(which contains images) and use the CloudFront URL to update code in /var/w...
