nginx配置文件的编写

以下是关于nginx配置文件编写的示例：

1. 配置监听端口和服务器名称

server {
    listen 80;
    server_name example.com;
}

2. 配置反向代理

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://localhost:3000;
    }
}

3. 配置负载均衡

upstream backend {
    server backend1.example.com weight=5;
    server backend2.example.com;
}

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://backend;
    }
}

4. 配置SSL

server {
    listen 443 ssl;
    server_name example.com;

    ssl_certificate /etc/nginx/ssl/example.com.crt;
    ssl_certificate_key /etc/nginx/ssl/example.com.key;

    location / {
        proxy_pass http://localhost:3000;
    }
}
