Now you can create your own Dynamic services like no-IP but with your own domain and no need to depend on any service provider. How and why to have your own dynamic DNS?
I am hosting some parts of our Linux SME portal from my by broadband, now you may be surprised why the hell I am doing that? I got a stable net and why I can’t use it?. the only issue is My ISP provides Dynamic IP. I don’t use any dynamic service providers.
one of the excellent coders provided free option to implement Dynamic DNS on my domain. YOu can get more details from below video
At present, it works with Godaddy but it works with any DNS provider who enables API based remote zone management.
How it works?
1.Shell script which connects to Godaddy and updates subdomains related linuxsme.com whenever my broadband ip changes.
2.YOu can see exactly how to implement and download the script from the above video.
Virtualization enabled every laptop to act as a Super Computer. Very efficient but what about overheat problem due to less efficient cooling system of the laptop. Low-cost cooling pads can work for 5-6 Degrees only. More than that need costly ones.
If you have purifier like Mi Air purifier you can use it as an excellent external cooling system for your laptop.
How to use Mi Air Purifier as an external cooling system to reduce 20 C temperature?
My Dell 7490 holding Vmware, Virtualbox with 32 GB RAM and cheap cooling pad unable to reduce as expected. So on weekend, I tried using Air Purifier as a cooling fan for my laptop.
So now result of using Air purifier as external cooling system
Above result achieved by keeping mode 3 of purifier which is noisy. If you keep Auto mode, you can reduce 15-20 degree C without any noise.
In this way, we can use Air purifier as an external cooling system for laptops which are overloaded with Virtualization tools.
The result is good but I am not aware of side effects on the laptop board with this air blow. Please leave your comment.
Rundeck I tried as a weekend project but it went more than what I expected. RunDeck is an automation tool. You can get more about on their website. Open Source version also available.
My attempt was to configure RunDeck and use to create or provision of VM on OCI. I know it is blind shot as I don’t have any knowledge of this tool and integration with Terraform.
YOu cann our Raw cut video of Rundeck on Ubuntu. Please note it is not plosihed video.
2 GB, 2 CPU Ubuntu vm used as RunDeck installation. It was fine.
No Problem part. http://localhost:4441 is the URL fro admin it. So I used my VM IP and called it as 192.168.1.100:4441. Nice! it responded well and given login box. all went well that’s it RunDeck Hung after entering initial login which is admin/admin. I keep on watching more than 10 mins, suspecting my low memory.
Then tried different browsers no use! I saw an old thread on the Internet that caused me to think about it. Bug or Feature. Post-install, you need to change URL in config.properties file. Someone says it is a feature to customize it. Some say it is Bug.
May be too early to comment as I didn’t read complete documentation but I am not alone as per Google facing this issue. It’s a great tool so we can ignore this glitch!
Solution to fix RunDeck initial login is :
# change hostname here
Bingo! then ti worked.
Now the major part is how to call Terraform from RunDeck. I will update next Weekend If I am successful in integrating Terraform and Rundeck
Excellent question! While posting my story of Linuxsme on YouTube channel, my friend this question.
In fact, I am hosting this web site using Oracle Cloud – OCI – free tier compute node only. Ocpus are much powerful than other Cloud providers? we will see you soon. I am using OCI + SPark from adobe along with YouTube.
Non-APACHE based stack makes a lot of difference for limited resources VMS or Computenodes. Now, Http/2 seems to make some improvements to SSL based sites. Our site also SSL that too from “letsencrypt” for $0.
I am new to social media – can you believe – I don’t have Facebook Page!
Everything I installed by my own not Docker-based or any ready to use the stuff! Linux SRE needs to build such ready to use stuff. To build Stuff, first, you need to know how internals.
So LNMP + Adobe Spark + YouTube + OCI + MailChimo + WordPress = LinuxSME.com. Soon I going to present Linux and SRE related stuff.
Now System Admin job marked as Legacy and no more required by the IT industry. Its pain in the heart by seeing System admin jobs section removing from Organization job list. Now everyone wants SRE. It’s not a title change its complete change of mindset from System Admin.
What a respect SAs used to get in the organization!.Now SRE. Google started this concept of SRE in 2003 I think. But after Devops got good demand since 2011. now SRE came to picture. Although DevOps and ARE not same but interrelated now.
SRE means Site Reliability Engineer. A person with SA and Development skill set. 50:50 role. A developer can become System Admin but its hard for SA to become Developer. I am also now in the same boat. I will start my SRE journey on this blog. One thing is sure, a lot of learning curve ahead. You need to know the basics of DevOps tools and one language ( Python is the best choice). Just writing crude Bash scripts no more works!. Welcome to how to become SRE from SA role series.
how to become a site reliability engineer? how to become an sre?
how to become site reliability engineer?
All of the above questions are same as well answer also as mentioned above.
It’s everywhere Ansible now. So I am also stepping in the world of YAML world of double space Indent. Today spent some money Ansible courses, hope my investment will give much more returns than what I expect. Oh! I am greedy !. I will try to share here, my learnings. Whoever wants to learn Ansible, instead of jumping directly on the product, first learn YAML. So will start YAML today onwards.
K I, S.S this is best suits for Kapow software. Some times tiny software utilities help than complex paid software. How do you know the total time you spend on Laptop or Desktop task vice? you will say some Cloud-based app or some paid stuff. no need you can enjoy with Kapow utility which helps. It won’t require even the internet.
