如何无需指定端口在Nginx上运行Symfony PHP项目？

问题描述 #

我使用Docker部署基于Symfony框架的PHP项目，包含Nginx、PHP和PostgreSQL服务。该项目之前在其他电脑上可无需指定端口通过http://bp.project访问，但当前电脑仅能通过http://bp.project:82访问，直接访问http://bp.project则失败。

当前配置 #

Nginx配置（nginx.conf） #

server {

    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    server_name bp.project;
    root /var/www/html/public/;
    index index.php;

    location / {
         try_files $uri $uri/ /index.php$is_args$args;
    }

    location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_pass php-upstream;
        fastcgi_index index.php;

        fastcgi_read_timeout 600;
        include fastcgi_params;

解决方案 #

• 修改Docker Compose端口映射：将Nginx服务的ports配置从"82:80"改为"80:80"。浏览器访问HTTP协议时默认使用80端口，不指定端口会自动请求80端口，将容器80端口映射到主机80端口后，即可直接通过http://bp.project访问。

  ports:
    - "80:80"
  

• 检查并释放80端口占用：如果主机80端口被本地Nginx、Apache、IIS等服务占用，需先停止这些服务。
  • Windows：打开命令提示符执行netstat -ano | findstr ":80"找到进程ID，再用taskkill /PID <进程ID> /F终止进程。
  • Linux/macOS：执行sudo lsof -i :80找到进程，再用sudo kill -9 <进程ID>终止进程。
• 确认本地hosts文件配置：确保bp.project已映射到127.0.0.1。
  • Windows：编辑C:\Windows\System32\drivers\etc\hosts，添加一行127.0.0.1 bp.project。
  • Linux/macOS：编辑/etc/hosts，添加一行127.0.0.1 bp.project。
• 重启Docker服务：修改配置后，执行docker-compose down && docker-compose up -d重启所有服务，使配置生效。
