Nginx 配置前端后端服务的实现步骤

server {
    listen 80;
    server_name your_domain.com;  # 替换为域名或IP地址
 
    location / {
        root /var/www/frontend;
        index index.html;
        try_files $uri $uri/ /index.html;  # 确保刷新页面时返回index.html
    }
}

server {
    listen 80;
    server_name your_domain.com;  # 替换为域名或IP地址
 
    location / {
        root /var/www/frontend;
        index index.html;
        try_files $uri $uri/ /index.html;  # 确保刷新页面时返回index.html
    }
 
    location /api/ {  # 假设后端API的路径以/api/开头
        proxy_pass http://localhost:3000/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
