## 手动安装多PHP版本 ### 1. 安装Nginx和MySQL ```bash # Ubuntu/Debian sudo apt update sudo apt install nginx mysql-server mysql-client # CentOS/RHEL sudo yum install nginx mysql-server mysql ``` ### 2. 安装PHP 7.4和8.2 ```bash # Ubuntu/Debian sudo apt install software-properties-common sudo add-apt-repository ppa:ondrej/php sudo apt update # 安装PHP 7.4 sudo apt install php7.4 php7.4-fpm php7.4-mysql php7.4-cli \ php7.4-curl php7.4-gd php7.4-mbstring \ php7.4-xml php7.4-zip # 安装PHP 8.2 sudo apt install php8.2 php8.2-fpm php8.2-mysql php8.2-cli \ php8.2-curl php8.2-gd php8.2-mbstring \ php8.2-xml php8.2-zip ``` ### 3. 配置PHP-FPM ```bash # 配置PHP 7.4 FPM监听不同端口 sudo nano /etc/php/7.4/fpm/pool.d/www.conf # 修改：listen = 127.0.0.1:9074 # 配置PHP 8.2 FPM sudo nano /etc/php/8.2/fpm/pool.d/www.conf # 修改：listen = 127.0.0.1:9082 # 重启服务 sudo systemctl restart php7.4-fpm php8.2-fpm ``` ### 4. 配置Nginx虚拟主机 ```bash # 创建PHP 7.4站点配置 sudo nano /etc/nginx/sites-available/php74-site ``` ```nginx server { listen 80; server_name php74.yourdomain.com; root /var/www/php74; index index.php index.html; location ~ \.php$ { include snippets/fastcgi-php.conf; fastcgi_pass 127.0.0.1:9074; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } ``` ```bash # 创建PHP 8.2站点配置 sudo nano /etc/nginx/sites-available/php82-site ``` ```nginx server { listen 80; server_name php82.yourdomain.com; root /var/www/php82; index index.php index.html; location ~ \.php$ { include snippets/fastcgi-php.conf; fastcgi_pass 127.0.0.1:9082; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } ``` ### 5. 启用站点并测试 ```bash # 创建网站目录 sudo mkdir -p /var/www/{php74,php82} # 创建测试文件 echo "<?php phpinfo(); ?>" | sudo tee /var/www/php74/index.php echo "<?php phpinfo(); ?>" | sudo tee /var/www/php82/index.php # 启用站点 sudo ln -s /etc/nginx/sites-available/php74-site /etc/nginx/sites-enabled/ sudo ln -s /etc/nginx/sites-available/php82-site /etc/nginx/sites-enabled/ # 测试配置并重启 sudo nginx -t sudo systemctl reload nginx ``` ## 管理脚本示例 ```bash #!/bin/bash # manage-multi-php.sh case $1 in start) sudo systemctl start php7.4-fpm php8.2-fpm nginx mysql ;; stop) sudo systemctl stop php7.4-fpm php8.2-fpm nginx ;; restart) sudo systemctl restart php7.4-fpm php8.2-fpm nginx ;; status) sudo systemctl status php7.4-fpm php8.2-fpm nginx ;; *) echo "Usage: $0 {start|stop|restart|status}" ;; esac ``` ## 测试验证 ```bash # 测试PHP 7.4 curl -H "Host: php74.yourdomain.com" http://localhost/info.php # 测试PHP 8.2 curl -H "Host: php82.yourdomain.com" http://localhost/info.php # 命令行验证 php7.4 -v php8.2 -v ``` ## 推荐建议 1. **开发环境**：使用Docker方案，隔离性好，管理方便 2. **生产环境**：方案二更稳定，资源占用更少
