How to Publish Yii on AWS?

To publish Yii on AWS, you need to follow the steps mentioned below:

1. Set up an AWS account: Sign up for an AWS account if you haven't already done so. This will require providing your email address and some additional information.
2. Launch an EC2 instance: EC2 is Amazon's Elastic Compute Cloud service, which provides virtual servers in the cloud. Launch an EC2 instance with the appropriate configuration for your Yii application.
3. Install and configure PHP: Connect to the EC2 instance using SSH and install PHP on the server. Make sure to install the required extensions and dependencies for your Yii framework.
4. Install and configure a web server: You need to install a web server like Apache or Nginx to serve your Yii application. Configure the web server to point to the correct directory where your Yii application resides.
5. Set up a database: Yii applications typically use a database to store and retrieve data. Install the appropriate database server like MySQL or PostgreSQL and configure it to work with your Yii application.
6. Deploy your Yii application: Transfer your Yii application files to the EC2 instance using a secure file transfer protocol like SFTP. Ensure that the files are placed in the correct directory, as specified in the web server configuration.
7. Set up DNS: Configure your domain name to point to the public IP address of your EC2 instance. This can be done by creating a DNS record in your domain registrar's control panel.
8. Test your application: Access your Yii application using the domain name you set up in the previous step. Ensure that everything is working correctly and that your Yii application is accessible.
9. Configure SSL certificate (optional): If you want to secure your Yii application with HTTPS, obtain an SSL certificate and configure the web server to use it.
10. Set up monitoring and backups: Configure monitoring tools and automated backups to ensure the health and availability of your Yii application. AWS provides various services and tools for this purpose, such as CloudWatch and AWS Backup.

By following these steps, you should be able to publish your Yii application on AWS and make it accessible to users over the internet.

How to use CloudFormation for Yii application deployment on AWS?

To use CloudFormation for Yii application deployment on AWS, follow these steps:

1. Define your CloudFormation template: Create a YAML or JSON CloudFormation template that includes the necessary resources for your Yii application deployment. This may include an EC2 instance, RDS database, Elastic Load Balancer, security groups, VPC, etc. Define the necessary parameters and mappings for your template.
2. Include the necessary user data: In the EC2 instance resource section of your CloudFormation template, include user data that installs the necessary software and dependencies for your Yii application. This may include PHP, MySQL, Apache or Nginx, and any other required libraries or modules.
3. Create a CloudFormation stack: Use the AWS Management Console, AWS CLI, or SDKs/APIs to create a CloudFormation stack using your template. Provide the necessary input parameters, such as the instance type, database credentials, etc.
4. Monitor the stack creation: Monitor the status of the CloudFormation stack creation process. You can check the progress and any errors or warnings in the AWS Management Console or using the AWS CLI.
5. Configure application settings: Once the stack creation is complete, configure the necessary application settings, such as database connection details, in your Yii application's configuration files. This may involve editing the main.php or params.php file to set the database credentials, cache settings, and other configurations.
6. Deploy the Yii application code: Upload your Yii application code to the EC2 instance created by your CloudFormation stack. This can be done by copying the code using SCP or SFTP, pulling from a Git repository, or using other deployment methods such as AWS CodeDeploy or Elastic Beanstalk.
7. Test the deployment: Access your deployed Yii application using the public IP or domain name of the EC2 instance. Make sure that the application is functioning correctly and that it can communicate with the RDS database if applicable.

By following these steps, you can use CloudFormation to automate the provisioning and deployment of your Yii application on AWS. This allows for easy replication and scaling of your application infrastructure.

What is AWS Elastic Load Balancer (ELB)?

The AWS Elastic Load Balancer (ELB) is a managed service provided by Amazon Web Services (AWS) that automatically distributes incoming application traffic across multiple Amazon Elastic Compute Cloud (EC2) instances. It helps improve the availability and fault tolerance of applications by distributing traffic across multiple instances, ensuring that no single instance is overloaded. ELB automatically scales up and down based on demand and performs health checks to ensure that only healthy instances receive traffic. There are three types of ELB offered by AWS: Classic Load Balancer, Network Load Balancer, and Application Load Balancer, each with different features and use cases.

What is AWS CloudWatch?

AWS CloudWatch is a monitoring and observability service provided by Amazon Web Services (AWS). It allows users to collect and track metrics, collect and monitor log files, set alarms, and automatically react to changes in AWS resources. CloudWatch provides a comprehensive view of the operational health and performance of an AWS infrastructure, allowing users to gain insights into resource utilization, application performance, and overall operational health. It also provides the ability to visualize logs, create custom dashboards, and generate reports to efficiently monitor and troubleshoot application and system performance.

How to obtain an SSL certificate for Yii on AWS using Certificate Manager?

To obtain an SSL certificate for Yii on AWS using Certificate Manager, follow the steps below:

1. Sign in to the AWS Management Console and go to the Amazon Certificate Manager (ACM) service.
2. Choose "Request a certificate".
3. In the ACM wizard, choose "Request a public certificate" and click "Request a certificate" button.
4. Add the domain names for which you want to obtain the SSL certificate. For Yii, you would typically include your domain (e.g., example.com) and any subdomains (e.g., www.example.com). You can add multiple domain names by typing them in the "Domain name" field, separating them with a comma.
5. Select the validation method for the certificate. AWS Certificate Manager offers different methods for validating domain ownership, including email validation, DNS validation, or validation through an AWS service (Route 53). Choose the method that suits your needs and follow the instructions to complete the validation process.
6. Review the request details and click "Confirm and request" to submit the certificate request.
7. Once the request is submitted, ACM will attempt to validate the domain ownership.
8. After successful validation, your certificate will be issued and ready to use. You can find it under "Certificate Manager" in the AWS console.
9. To use the certificate with your Yii application hosted on AWS, you can either deploy your application on an AWS Elastic Beanstalk environment or set up an Application Load Balancer (ALB) for your application. Both Elastic Beanstalk and ALB offer easy integration with ACM certificates.
10. If using Elastic Beanstalk, you can specify the ACM certificate while creating or updating your environment. Choose the appropriate certificate from the "SSL certificate ID" dropdown menu.
11. If using an ALB, you can bind the ACM certificate to the ALB listener. Open the Amazon EC2 console, navigate to the "Load Balancers" section, select your ALB, go to the "Listeners" tab, and edit the listener configuration. In the "Listener" pane, select your ACM certificate from the "Default SSL certificate" dropdown menu.

By following these steps, you can obtain an SSL certificate for Yii on AWS using Certificate Manager and configure your application to use it, ensuring secure HTTPS communication.
