When deploying Laravel applications, you need to pay attention to environment configuration, web server settings, cache optimization and database management. 1. Ensure that the production and development environment PHP version are consistent and the necessary extensions are installed, and the configuration is managed and the keys are generated using .env; 2. The production environment should use Nginx or Apache, correctly configure the request to point to public/index.php and set permissions; 3. Use config:cache, route:cache and view:cache to improve performance and handle queue and timing tasks reasonably; 4. Execute migrate and db:seed carefully during deployment, and combine version control to avoid data corruption.

Deploying a Laravel application may not be difficult, but it still requires some experience and attention to it to run stably and efficiently. Here are some common strategies and precautions in actual operation.

1. Environment configuration and consistency

Laravel relies on the environment more often, especially in PHP extensions and configuration. Before deployment, make sure that the PHP version of the production environment is consistent with the development environment and install necessary extensions, such as:

• OpenSSL
• PDO
• Mbstring
• Tokenizer
• XML
• Ctype
• JSON
• BCMath

In addition, it is recommended to use .env files to manage configurations for different environments, and do not submit sensitive information to the code base. You can use php artisan key:generate to generate the application key.

2. Use the appropriate web server configuration

By default, Laravel comes with a simple development server ( php artisan serve ), but this is not suitable for production environments. Nginx or Apache is recommended in production environments.

Taking Nginx as an example, the key point of the configuration file is to make all requests point to public/index.php , which can ensure that the framework handles routing normally.

Simple configuration example:

 server {
    listen 80;
    server_name yourdomain.com;
    root /path/to/your/laravel/public;

    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
    }
}

Don't forget to set the correct permissions, usually your web directory should belong to the www-data user or similar role.

3. Cache optimization and performance improvement

Laravel provides a variety of caching mechanisms, and rational use can significantly improve performance.

• Configuration cache : Execute php artisan config:cache and php artisan route:cache after the deployment is completed, which will cache configuration and routes as a file, reducing loading time.
• View Cache : If you use the Blade template, you can consider precompiling the view cache and use php artisan view:cache command.
• Queue and Task Scheduling : If there are background tasks, remember to start the queue worker ( php artisan queue:work ) or set the timed task (via schedule:run ).

However, it is important to note that once you modify the configuration or route, remember to clear the cache and regenerate it, otherwise it may cause strange problems.

4. Database migration and seed data

During the deployment process, database structure update problems are often encountered. Laravel's migration system is very useful, but be very careful when operating in production environments.

• After deployment, execute php artisan migrate to update the database structure.
• If there is a new table or field that requires initial data, you can use php artisan db:seed to insert the basic data.
• It is recommended to combine version control to record whether migration needs to be performed every time a new version is released.

Some teams will automatically execute these commands in the online scripts, but make sure to confirm that they will not corrupt existing data.

Basically that's it. Deploying Laravel applications is not complicated, but there are many details. The prone to errors is often not a big problem, but a small negligence. Doing a good job in inspection, testing and automation will save you a lot of trouble.
