Laravel VPS托管：PHP应用部署完整指南

Laravel需要PHP 8.2+、MySQL/MariaDB和Nginx（或Apache）。在Ubuntu VPS上安装完整LEMP栈：

apt update && apt upgrade -y
apt install -y nginx mysql-server

# 安装PHP 8.2和必要扩展
apt install -y software-properties-common
add-apt-repository ppa:ondrej/php
apt update
apt install -y php8.2-fpm php8.2-cli php8.2-mysql php8.2-xml     php8.2-mbstring php8.2-curl php8.2-zip php8.2-bcmath     php8.2-tokenizer php8.2-gd php8.2-redis

安装Composer（PHP依赖管理器）：

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
chmod +x /usr/local/bin/composer

运行MySQL安全初始化：

mysql_secure_installation

将Laravel项目部署到VPS并配置.env文件：

cd /var/www
git clone https://github.com/youruser/yourproject.git laravel-app
cd laravel-app
composer install --optimize-autoloader --no-dev
cp .env.example .env
php artisan key:generate

配置.env文件中的关键参数：

APP_ENV=production
APP_DEBUG=false
APP_URL=https://yourdomain.com

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_DATABASE=laravel_db
DB_USERNAME=laravel_user
DB_PASSWORD=your_strong_password

执行数据库迁移和优化：

php artisan migrate --force
php artisan config:cache
php artisan route:cache
php artisan view:cache

设置正确的文件权限：

chown -R www-data:www-data /var/www/laravel-app
chmod -R 755 /var/www/laravel-app/storage
chmod -R 755 /var/www/laravel-app/bootstrap/cache

为Laravel应用创建Nginx站点配置：

nano /etc/nginx/sites-available/laravel-app

Laravel官方推荐的Nginx配置：

server {
    listen 80;
    server_name yourdomain.com;
    root /var/www/laravel-app/public;
    index index.php index.html;

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

    location ~ .php$ {
        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ /.(?!well-known).* {
        deny all;
    }
}

ln -s /etc/nginx/sites-available/laravel-app /etc/nginx/sites-enabled/
nginx -t && systemctl reload nginx
certbot --nginx -d yourdomain.com

Laravel的队列系统和缓存层通过Redis可以显著提升应用性能。安装Redis并配置Laravel：

apt install -y redis-server
systemctl enable redis-server
systemctl start redis-server

在.env文件中启用Redis：

CACHE_DRIVER=redis
QUEUE_CONNECTION=redis
SESSION_DRIVER=redis
REDIS_HOST=127.0.0.1
REDIS_PORT=6379

创建Laravel队列worker的systemd服务：

nano /etc/systemd/system/laravel-worker.service

[Unit]
Description=Laravel Queue Worker
After=network.target

[Service]
User=www-data
WorkingDirectory=/var/www/laravel-app
ExecStart=/usr/bin/php artisan queue:work redis --sleep=3 --tries=3
Restart=always

[Install]
WantedBy=multi-user.target

systemctl enable laravel-worker
systemctl start laravel-worker

使用Laravel Scheduler配合crontab实现定时任务自动化，是替代复杂cron规则的优雅方案。
