Install and configure free secure SSL certificate in NGINX web server in Oracle Linux cloud

SSL certificates are used to secure our website and encrypt the details sent to the server. We will use a free self-signed SSL certificate and configure the SSL certificate using the NGINX web server. We need the oracle Linux cloud instance and NGINX server up and running. This step is prerequisite for this tutorial. Please refer to below link to install the oracle Linux and NGINX server. https://www.tech4learners.com/2022/01/how-to-create-linux-instance-with-24-gb.html https://www.tech4learners.net/2022/01/install-nginx-web-server-in-linux-cloud.html Once your compute instance and NGINX are up and running, proceed with the following steps. First step is to create PRIVATE / PUBLIC keys using the openssl command. We are using the RSA algorithm as an encryption method.  Replace the <IP_ADDRESS> with your Linux instance IP ADDRESS. sudo openssl req -new -x509 -days 30 -nodes -newkey rsa:2048 -keyout private.key \-out public.crt -subj '/C=US/ST=Ca/L=Sunnydale/CN=<IP_ADDRESS...

Enter the command  'sudo yum install nginx' again. Wait until the installation is complete. Step 3: We need to start the NGINX server once the installation is complete. Also, we need to make NGINX startup as a service.So that we don't need to start the NGINX server manually after reboot. Command to make the NGINX as a service is as follows. > sudo systemctl enable --now nginx.service Step 4: Verify the NGINX server status using the following command. > sudo systemctl status nginx Step 5: Add the HTTP firewall for port 80 using the ...

How to create Linux instance with 24 GB RAM 4 CPU using Oracle cloud server?

This tutorial will see how to create an oracle cloud Linux compute instance with 24 GB RAM and 4 CPUs. We will not use Putty keys to create and connect the Linux instance in this method. We will be using a public key /Private key generated by Oracle. Step 1.  Log in to your Oracle Cloud account and navigate to compute instance menu. Step 2. Click the Edit option in the Image and Shape section. Step 3. You can see 'AMD' shape is preselected. Click on Change Shape. Select 'AMPERE ARM-Based processor.' Click on the Shape name and choose the required CPU and memory. After finishing, click the 'select shape' button. Step 4: In the Add SSH keys part, select the 'Generate a key pair for me' option. Save private and public keys. Click the create button once keys are saved in the drive. Wait for a few seconds until the instance status shows as RUNNING. Verify the memory and CPU count in Shape configuration. Step 5: Download and install Mobaxterm SSH client from b...

How to access oracle Linux GUI through TigerVNC/TightVNC viewer

In this tutorial, We will see how to access the Oracle cloud Linux GUI through TightVNC Server. We have a private key(.ppk) created during the Putty key generation process. We need to make an SSH connection between our local PC and remote Linux server. To create an SSH connection, we need to convert the .ppk key to the OpenSSH key. If we use the private key directly, we will get the 'Invalid format' error. Follow the below steps to convert the PPK to the OpenSSH key. Open the PUTTY Key generator and load the private key. Enter the passphrase. Go to conversions and click 'Export OpenSSH key.' Save the key in the drive. I have kept the key in D: Drive. If we keep the key in D: drive, we will get the "Permissions for the key is too open" error. That's because D: drive is accessible to everyone. So, we are getting this error. So, copy the file to C:/users/<our user name> folder. Now Open the command prompt and enter the following command. > C:\Users\...
