MYSQL Setup

 

Login to the db vm

$ vagrant ssh db01

 

Verify Hosts entry, if entries missing update the it with IP and hostnames

# cat /etc/hosts

 

 

Update OS with latest patches

# yum update -y

 

Set Repository

# yum install epel-release -y

 

Install Maria DB Package

# yum install git mariadb-server -y

 

Starting & enabling mariadb-server

# systemctl start mariadb

# systemctl enable mariadb

 

RUN mysql secure installation script.

# mysql_secure_installation

NOTE: Set db root password, I will be using admin123 as password

 

Set root password? [Y/n] Y New password:

Re-enter new password:

Password updated successfully! Reloading privilege tables..

... Success!

 

By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation

go a bit smoother. You should remove them before moving into a production environment.

 

Remove anonymous users? [Y/n] Y

... Success!

 

Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n

... skipping.

 

By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.

 

Remove test database and access to it? [Y/n] Y

-  Dropping test database...

... Success!

-  Removing privileges on test database...

... Success!

 

Reloading the privilege tables will ensure that all changes made so far will take effect immediately.

 

Reload privilege tables now? [Y/n] Y

... Success!

 

 

Set DB name and users.

# mysql -u root -padmin123 mysql> create database accounts;

mysql> grant all privileges on accounts.* TO 'admin'@’%’ identified by 'admin123' ; mysql> FLUSH PRIVILEGES;

mysql> exit;

  Deploying Zomato Clone App with DevSecOps CI/CD Hello friends, we will be deploying a React Js Zomato-clone. We will be using Jenkins as a CICD tool and deploying our application on a Docker container. I Hope this detailed blog is useful. CLICK HERE FOR GITHUB REPOSITORY Steps:- Step 1 — Launch an Ubuntu(22.04) T2 Large Instance Step 2 — Install Jenkins, Docker and Trivy. Create a Sonarqube Container using Docker. Step 3 — Install Plugins like JDK, Sonarqube Scanner, Nodejs, and OWASP Dependency Check. Step 4 — Create a Pipeline Project in Jenkins using a Declarative Pipeline Step 5 — Install OWASP Dependency Check Plugins Step 6 — Docker Image Build and Push Step 7 — Deploy the image using Docker Step 8 — Terminate the AWS EC2 Instances. Now, let's get started and dig deeper into each of these steps:- STEP1:Launch an Ubuntu(22.04) T2 Large Instance Launch an AWS T2 Large Instance. Use the image as Ubuntu. You can create a new key pair or use an existing one. Enable HTTP and HTTP...

DevOps Project — CI/CD -3

Image
  In this blog, we are going to build and deploy our application on Docker Container with the help of Ansible. In the previous blog, we discussed the process of making changes on our workstation, followed by committing the changes using Git onto GitHub. Once the latest code is available on the Git repository, Jenkins is capable of fetching the updated code, initiating a build using Maven, creating Docker images, and subsequently deploying these Docker containers onto the Docker host. Link to last blog :  https://medium.com/@ahammed.jabirp/devops-project-ci-cd-2-5726966c20d2 Github :  https://github.com/jabir000/hello-world.git In that case, we used Jenkins as a tool for both building and deploying applications. However, are there any more efficient methods to manage this process? Yes, that is where we can introduce deployment tool. We are going to use Ansible as a deployment tool , so that Jenkins need not to do the administrative kind of activities. Because Jenkins is mo...
