This README provides a comprehensive guide on using Fabric for deploying code to a server, managing Nginx configuration, and executing commands both locally and remotely. Fabric is a Python library and command-line tool designed to simplify the process of remote administration and deployment tasks.

Fabric is a Python library and command-line tool that simplifies the process of executing commands remotely over SSH. It provides a simple and Pythonic interface for automating tasks such as deployment, system administration, and configuration management.

To deploy code to a server using Fabric, follow these steps:

1. Install Fabric using pip: pip install fabric.
2. Write a Fabric script (usually named fabfile.py) defining deployment tasks.
3. Define tasks for tasks like pulling code from a version control system, copying files to the server, restarting services, etc.
4. Execute the Fabric commands to run the deployment tasks defined in the fabfile.

Example of a simple fabfile.py:

from fabric import task

@task
def deploy(c):
    c.run("git pull origin main")
    c.run("docker-compose down")
    c.run("docker-compose up -d")

To execute the deployment task locally, run:

fab deploy

A tgz archive, also known as a tarball, is a compressed archive format commonly used in Unix-based systems. It combines multiple files into a single archive while compressing them using gzip compression. It's often used for packaging and distributing files or directories.

To execute a Fabric command locally, you can use the local context manager provided by Fabric. Here's an example:

from fabric import task

@task
def local_command(c):
    with c.local.cwd('/path/to/local/directory'):
        c.local('ls -la')

To run this command locally, execute:

fab local_command

To execute a Fabric command remotely, you can use the run function provided by Fabric within your task. Here's an example:

from fabric import task

@task
def remote_command(c):
    c.run('ls -la')

To run this command remotely, execute:

fab -H username@hostname remote_command

Fabric provides a put function to transfer files from the local system to a remote system and a get function to transfer files from the remote system to the local system. Here's an example:

from fabric import task

@task
def transfer_files(c):
    c.put('local_file.txt', '/remote/path/')
    c.get('/remote/path/remote_file.txt', 'local_destination/')

Nginx configuration management involves modifying configuration files typically found in /etc/nginx/conf.d/ or /etc/nginx/sites-available/. You can use Fabric to automate tasks related to Nginx configuration such as editing configuration files, reloading Nginx, etc.

Example task to reload Nginx:

from fabric import task

@task
def reload_nginx(c):
    c.sudo('systemctl reload nginx')

In Nginx configuration, root and alias directives are used to define the document root for requests matching a location block.

• root: Sets the root directory that will be used to search for a file to serve a request. It appends the request URI to the path specified.
• alias: Similar to root, but it replaces the part of the request URI that matches the location path with the specified path.

Example configuration:

server {
    listen 80;
    server_name example.com;

    location /files/ {
        root /var/www/;
    }

    location /images/ {
        alias /var/images/;
    }
}

In this example, requests to http://example.com/files/ will be served from /var/www/files/, while requests to http://example.com/images/ will be served from /var/images/.

• In web_flask directory, you will find a simple web application that connects to a MySQL database. The application uses the Flask framework to create a simple web interface that allows users to view and add data to a MySQL database.
• Templates are used to render HTML pages with dynamic content, and the application uses SQLAlchemy to interact with the MySQL database, using Jinja2.

• First, make sure you have the necessary dependencies installed by running the following command:

$ curl -o 100-dump.sql "https://s3.amazonaws.com/intranet-projects-files/holbertonschool-higher-level_programming+/290/100-hbnb.sql"
$ cat 100-dump.sql | mysql -uroot -p

• The above is to dump the database into your MySQL server. You will need to have MySQL installed on your machine and have the necessary permissions to create databases and tables.

• Flask web app:

$ HBNB_MYSQL_USER=hbnb_dev HBNB_MYSQL_PWD=hbnb_dev_pwd HBNB_MYSQL_HOST=localhost HBNB_MYSQL_DB=hbnb_dev_db HBNB_TYPE_STORAGE=db python3 -m web_flask.100-hbnb

• Run the application using the command above and visit http://localhost:5000 in your web browser to view the application.
• You can change 100-hbnb to any of the other Python files in the web_flask directory to test different parts of the application.
