海外TECH	DEV Community	TRUE WAY OF LEARNING TO CODE	https://dev.to/jagannathkrishna/true-way-of-learning-to-code-2c4p	TRUE WAY OF LEARNING TO CODEMany Beginner programmers learn code in the wrong way They learn to code like this Write all the information they learn in a notebook Learn all the syntax Learn some theories Learn all definitions etc You may know some other points if you are like this But after all these if someone told them to code a project the can t They tell so many definition theories etc but they can t code They don t know how to So we can understand this is not the true way of learning code The true way of learning code is is by Googling Yah You read that right Googling is the key If you forget a syntax just google it If you caught an error just google if you forget something else just google So when there is google you don t need to learn all things thoroughly Just understand the concept But the thing is if you forget some syntax you can google But you need to know where to put that in code That is the key No matter you copy amp pasted from stack overflow or from somewhere else you need to know where to paste it So Just understand the concept I hope you understood my message Also Share this message to beginner programmers This might help them Thank You For Reading Have a Nice day And comment is open for you valuable replies	2022-02-12 08:22:13
海外TECH	DEV Community	How to install an SSL certificate on a Bitnami stack hosted on Amazon Lightsail?	https://dev.to/thesameeric/how-to-install-an-ssl-certificate-on-a-bitnami-stack-hosted-on-amazon-lightsail-2jc5	How to install an SSL certificate on a Bitnami stack hosted on Amazon Lightsail In this note I ll be writing about how to install an SSL certificate on a Bitnami stack hosted on Amazon Lightsail For the purpose of this tutorial we ll be using WordPress installation on AWS Lightsail After days of figuring out the installation I finally got a short and quick way of doing it Let us get started Setting up Wordpress on AWS LightsailLog in to your AWS console In the search box inside the header search for Lightsail Click on it to go to the Lightsail console Once you re inside the Lightsail console Click on create instance button In the create instance screen you can choose your preferred instance location Under the instance image for the platform choose Linux Unix and App OS WordPress for Select a blueprint Scroll down to select your instance plan and pick a plan that supports your budget Under identify your instance give the instance a unique and descriptive name Click on create instance You ll wait a while for AWS to perform its magic Once the instance is created we can install the SSL certificate Linking your domain to your Lightsail instanceAfter the setup is complete the next step is to create a static IP address assign it to your new instance and link it to a domain The domain can either be on AWS or on any other domain registry The following steps will guide you through the process In your Lightsail console click on the networking tabClick on create static IP Choose the instance you want to add the static IP to Then give it a unique name to identify it Click on create and it will generate a new static IP and attach it to your instance Add the static IP to your DNS server Installing SSL certificateWe ll need to ssh into the instance to add the SSL certificate We will be using the Lightsail web terminal for this To begin click on the terminal icon on the instance card If it launches successfully you ll see a screen like the one below If you ve reached this point the next thing we ll do is to run the command sudo opt bitnami bncert tool You ll get a prompt that an update for the tool is available Enter Y Yes to update the tool It is best to use the most recent version of the tool The tool will exit and run the update After the update has run successfully run the command sudo opt bitnami bncert tool again This time you will get a prompt to enter the domain names separated by space you then enter your domain name i e somethingfishy com www somethingfishy comNOTE make sure to add only domain names that have been added to your DNS server to avoid an error After entering the domain names hit enter and allow the tool to work After a few seconds another prompt will appear to enable redirection from HTTP to HTTPS enter Y and continue If you added a www domain to your list in the previous step you would also get a prompt to redirect www or t non www domain Yet another prompt will appear a few seconds after you hit enter from the previous step This time it will list about changes it wants to perform on your Binami instance Enter Y and hit enter You ll get another one to accept the LetsEncrypt subscriber s agreement Enter Y and click on continue After this you should get a success message with the directories where the certs are click on continue and close the terminal You can visit your site now Extra to get your Wordpress admin password use the command cat HOME bitnami application passwordPlease Like Share and Subscribe	2022-02-12 08:07:27
