Docker Installation of Symfony: One-Click Deployment Guide
Introduction:
Symfony is a popular PHP framework that provides powerful tools and functions for convenience Developers build high-performance, scalable web applications. Docker is an open source containerization platform that can package applications and their running environments into an independent, portable container, making application deployment and management easier. This article will introduce how to use Docker to quickly and easily deploy Symfony.
Part One: Preparation
Before we start deploying Symfony, we need to ensure that Docker and Docker Compose have been installed in our development environment. You can find the corresponding installation tutorial on the Docker official website.
Part 2: Create a Symfony application
First, we need to create a Symfony application. Open a terminal and enter a directory used to store applications, and execute the following command:
$ docker run --rm -v $(pwd):/app composer create-project symfony/website-skeleton my_app
This command will create a Symfony application named my_app in the current directory.
Part 3: Configure the Docker Compose file
Create a file named docker-compose.yml in the project root directory and write the following content:
version: '3' services: php: build: context: . dockerfile: docker/php/Dockerfile volumes: - .:/var/www/html nginx: image: nginx:latest ports: - 80:80 volumes: - .:/var/www/html - ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf mysql: image: mysql:latest environment: MYSQL_ROOT_PASSWORD: root volumes: - db_data:/var/lib/mysql volumes: db_data:
This configuration file Three services are defined: php, nginx and mysql. The php service is built using a Dockerfile. We need to create a directory named docker/php in the project root directory, create a Dockerfile file in this directory, and write the following content:
FROM php:7.4-fpm-alpine RUN docker-php-ext-install pdo_mysql WORKDIR /var/www/html
This The Dockerfile defines a Docker container based on the php:7.4-fpm-alpine image, installs the pdo_mysql extension, and sets the working directory to /var/www/html.
Create a file named default.conf in the docker/nginx directory and write the following content:
server { listen 80; server_name localhost; root /var/www/html/public; location / { try_files $uri /index.php$is_args$args; } location ~ ^/index.php(/|$) { fastcgi_pass php:9000; fastcgi_split_path_info ^(.+.php)(/.*)$; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_path_info; } }
This configuration file defines the Nginx virtual host and forwards the request to the PHP service .
Part 4: Start the application
Execute the following command in the project root directory to start the application:
$ docker-compose up -d
This command will start three containers: php, nginx and mysql, and Runs in the background.
Part 5: Access the application
Access http://localhost in the browser to see the welcome page of the Symfony application.
Conclusion:
By using Docker, we can deploy Symfony applications quickly and easily. With just a few simple steps, you can easily set up a Symfony development environment. Docker's containerization technology makes application deployment and management simpler and more reliable, greatly improving development efficiency and application scalability. I hope this article is helpful to everyone, and I wish you a happy Symfony development journey!

The basic structure of Linux includes the kernel, file system, and shell. 1) Kernel management hardware resources and use uname-r to view the version. 2) The EXT4 file system supports large files and logs and is created using mkfs.ext4. 3) Shell provides command line interaction such as Bash, and lists files using ls-l.

The key steps in Linux system management and maintenance include: 1) Master the basic knowledge, such as file system structure and user management; 2) Carry out system monitoring and resource management, use top, htop and other tools; 3) Use system logs to troubleshoot, use journalctl and other tools; 4) Write automated scripts and task scheduling, use cron tools; 5) implement security management and protection, configure firewalls through iptables; 6) Carry out performance optimization and best practices, adjust kernel parameters and develop good habits.

Linux maintenance mode is entered by adding init=/bin/bash or single parameters at startup. 1. Enter maintenance mode: Edit the GRUB menu and add startup parameters. 2. Remount the file system to read and write mode: mount-oremount,rw/. 3. Repair the file system: Use the fsck command, such as fsck/dev/sda1. 4. Back up the data and operate with caution to avoid data loss.

This article discusses how to improve Hadoop data processing efficiency on Debian systems. Optimization strategies cover hardware upgrades, operating system parameter adjustments, Hadoop configuration modifications, and the use of efficient algorithms and tools. 1. Hardware resource strengthening ensures that all nodes have consistent hardware configurations, especially paying attention to CPU, memory and network equipment performance. Choosing high-performance hardware components is essential to improve overall processing speed. 2. Operating system tunes file descriptors and network connections: Modify the /etc/security/limits.conf file to increase the upper limit of file descriptors and network connections allowed to be opened at the same time by the system. JVM parameter adjustment: Adjust in hadoop-env.sh file

This guide will guide you to learn how to use Syslog in Debian systems. Syslog is a key service in Linux systems for logging system and application log messages. It helps administrators monitor and analyze system activity to quickly identify and resolve problems. 1. Basic knowledge of Syslog The core functions of Syslog include: centrally collecting and managing log messages; supporting multiple log output formats and target locations (such as files or networks); providing real-time log viewing and filtering functions. 2. Install and configure Syslog (using Rsyslog) The Debian system uses Rsyslog by default. You can install it with the following command: sudoaptupdatesud

When choosing a Hadoop version suitable for Debian system, the following key factors need to be considered: 1. Stability and long-term support: For users who pursue stability and security, it is recommended to choose a Debian stable version, such as Debian11 (Bullseye). This version has been fully tested and has a support cycle of up to five years, which can ensure the stable operation of the system. 2. Package update speed: If you need to use the latest Hadoop features and features, you can consider Debian's unstable version (Sid). However, it should be noted that unstable versions may have compatibility issues and stability risks. 3. Community support and resources: Debian has huge community support, which can provide rich documentation and

This article describes how to use TigerVNC to share files on Debian systems. You need to install the TigerVNC server first and then configure it. 1. Install the TigerVNC server and open the terminal. Update the software package list: sudoaptupdate to install TigerVNC server: sudoaptinstalltigervnc-standalone-servertigervnc-common 2. Configure TigerVNC server to set VNC server password: vncpasswd Start VNC server: vncserver:1-localhostno

Configuring a Debian mail server's firewall is an important step in ensuring server security. The following are several commonly used firewall configuration methods, including the use of iptables and firewalld. Use iptables to configure firewall to install iptables (if not already installed): sudoapt-getupdatesudoapt-getinstalliptablesView current iptables rules: sudoiptables-L configuration
