Some commonly used rapid deployment tools and techniques in PHP

With the continuous development of the Internet industry, PHP has become the preferred development language for many companies. Rapid deployment of PHP applications is a skill that must be mastered in the PHP development process. This article will introduce some commonly used rapid deployment tools and techniques, hoping to be helpful to PHP developers.

1. Using Docker

Docker is one of the popular containerization technologies and one of the common tools for quickly deploying PHP applications. Using Docker, we can easily create and deploy PHP applications to avoid configuration conflicts caused by application environment and other issues. The following are the steps to quickly deploy PHP applications using Docker:

1. Installing Docker

First, we need to install Docker in our development environment. You can download the installation package for the corresponding operating system through the official website, and start Docker after the installation is complete.

2. Writing Dockerfile

Dockerfile is the blueprint for Docker to create a container, which contains the required environment, software packages and other information. When writing a Dockerfile, you can start from the officially provided PHP image.

The following is a basic PHP Dockerfile example:

# 基础镜像
FROM php:7.2-apache

# 安装依赖
RUN apt-get update && \
    apt-get install -y git && \
    apt-get install -y curl && \
    apt-get install -y libpng-dev && \
    apt-get install -y libcurl4-openssl-dev

# 安装扩展
RUN docker-php-ext-install pdo_mysql mysqli gd curl

# 启用Apache Rewrite模块
RUN a2enmod rewrite

# 设置Apache网站根目录
ENV APACHE_DOCUMENT_ROOT /var/www/html/public
RUN sed -ri -e 's!/var/www/html!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/sites-available/*.conf
RUN sed -ri -e 's!/var/www/!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/apache2.conf /etc/apache2/conf-available/*.conf

# 维护者信息
LABEL maintainer="yourname@company.com"

# 工作目录
WORKDIR /var/www/html

# 复制代码及资源
COPY . /var/www/html

# 安装Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin/ --filename=composer

# 安装PHP依赖
RUN composer install --no-dev --no-interaction --no-progress --prefer-dist

# 暴露端口
EXPOSE 80

At this point, run the following command in the current directory to build the image in Docker:

$ docker build -t my_php_app .

Among them, "my_php_app" The name of the created image.

3. Run the Docker container

After the build is successful, use the following command to run the container in Docker:

$ docker run -it -p 80:80 my_php_app

In the above command, "-p 80 :80" means mapping port 80 inside Docker to local port 80, and you can access the PHP application by accessing the IP address of the local host through a browser. At this point, we have successfully deployed a PHP application using Docker.

2. Use Web Server

In addition to Docker, you can use common web servers (such as Nginx and Apache) to quickly deploy PHP applications.

1. Configuring the Web Server

First, you need to configure the Web server to support PHP. Taking Nginx as an example, you can configure it according to the following steps:

• Install Nginx and PHP related components

$ sudo apt-get update
$ sudo apt-get install -y nginx php-fpm php-mysql

• Configure Nginx

Open the Nginx configuration file:

$ sudo nano /etc/nginx/sites-available/default

Add the following content to the file:

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/html;
    index index.php;

    server_name _;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    }
}

Run the following command to restart the nginx service:

$ sudo service nginx restart

2. Deploy the application

After completing the relevant configuration, you can place the application file in the root directory of the website (default is /var/www/html) and ensure that it can be accessed by Nginx.

3. Using scripts

In addition to Docker and Web servers, another common way to quickly deploy PHP applications is to use scripts. You can write a deployment script to automatically complete the entire process from code repository pulling, environment configuration to application deployment. The following is a simple deployment script example:

#!/bin/bash

# 部署程序

# 从Git仓库拉取代码
git clone https://github.com/user/my_php_app.git

# 进入代码目录
cd my_php_app

# 安装依赖
composer install

# 配置环境变量
cp .env.example .env

# 自动生成应用密钥
php artisan key:generate

# 运行数据库迁移
php artisan migrate

# 启动服务
php artisan serve

In the deployment script, we can use some common tools and commands, such as Composer, Git, PHP Artisan, etc. It can be adjusted and modified according to actual needs.

Summary

Rapid deployment of PHP applications is one of the skills that must be mastered in the PHP development process. In this article, we introduce some commonly used rapid deployment tools and techniques, including Docker, web servers, and scripts. I hope this content will be helpful to PHP developers and speed up development productivity.
