This time I will bring you a detailed explanation of the containerization and deployment of PHP applications. What are the precautions for containerization and deployment of PHP applications? The following is a practical case, let's take a look.
PHP is the best language in the world.
The classic LNMP (linux nginx php mysql) environment has many ready-made deployment scripts, but today when Docker is popular, many students still have some problems on how to deploy, so this article is simple Introduce how to use Docker and docker-compose to deploy php applications on the server. First of all, let’s review the past php configuration in nginx:location ~ \.php$ { try_files $uri =404; include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; }All php files are parsed using the php engine, and php runs on the local port 9000 (accessible through ip/unix domain sockets) , since it can be local, of course it can also be parsed through remote services. So our nginx service is configured as follows:
server { listen 80; charset utf-8; # access_log /var/log/nginx/nginx.access.log main; # error_log /var/log/nginx/error.log; root /var/www/html; index index.php index.html; add_header X-Cache $upstream_cache_status; location ~ \.php$ { try_files $uri =404; include fastcgi_params; fastcgi_pass php-fpm:9000; fastcgi_index index.php; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; } }At the same time, a more difficult problem is that the php code needs to exist in both nginx and php engines, otherwise it cannot be parsed, but this It’s not a problem, docker’s volume naturally supports it! Look directly at the docker-compose.yml configuration below:
version: '2' services: nginx: image: nginx:stable-alpine ports: - 80:80 volumes: - ./conf/nginx/conf.d:/etc/nginx/conf.d volumes_from: - php-fpm restart: always php-fpm: image: php:7.1-fpm-alpine volumes: - ./code:/var/www/html restart: alwaysNote: php-fpm mounts the local directory code to /var/www/html
nginx conf uses service_name to access php-fpm
nginx shares php-fpm's /var/www/html through the volumes_from directive
Write this in index.php in the code directory:
<?php echo phpinfo();Then run:
# bash docker-compose upOpen the browser and you can see the familiar phpinfo:
FROM php:7.1-fpm-alpine RUN docker-php-install pdo pdo-mysql COPY src /var/www/htmlTo build, you can choose the Alibaba Cloud Image Service build function or the automatic build provided by Docker, and then update the previous docker-compose.yml That’s it:
version: '2' services: nginx: image: nginx:stable-alpine ports: - 8000:80 volumes: - ./conf/nginx/conf.d:/etc/nginx/conf.d volumes_from: - php-fpm restart: always php-fpm: image: {YOUR_PHP_IMAGE_NAME}:{TAG} restart: alwaysI believe you have mastered the method after reading the case in this article.

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.

To destroy a PHP session, you need to start the session first, then clear the data and destroy the session file. 1. Use session_start() to start the session. 2. Use session_unset() to clear the session data. 3. Finally, use session_destroy() to destroy the session file to ensure data security and resource release.

How to change the default session saving path of PHP? It can be achieved through the following steps: use session_save_path('/var/www/sessions');session_start(); in PHP scripts to set the session saving path. Set session.save_path="/var/www/sessions" in the php.ini file to change the session saving path globally. Use Memcached or Redis to store session data, such as ini_set('session.save_handler','memcached'); ini_set(

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.
