Nginx 配置网址（一个或多个）指南

Nginx 可以通过 server 块配置一个或多个网址（域名）。以下是配置方法：

单个网址配置

nginx
server {
listen 80;
server_name example.com; 你的域名

location / {
root /var/www/example.com; 网站文件目录
index index.html index.htm;
}
}

多个网址配置

方法1：多个 server 块

nginx
server {
listen 80;
server_name example.com;

location / {
root /var/www/example.com;
index index.html index.htm;
}
}

server {
listen 80;
server_name another.com;

location / {
root /var/www/another.com;
index index.html index.htm;
}
}

方法2：一个 server 块多个域名

nginx
server {
listen 80;
server_name example.com another.com third.com;

location / {
root /var/www/shared; 所有域名共享同一目录
index index.html index.htm;
}
}

HTTPS 配置（SSL证书）

nginx
server {
listen 443 ssl;
server_name example.com;

ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/key.pem;

location / {
root /var/www/example.com;
index index.html index.htm;
}
}

常用配置选项

1、重定向 HTTP 到 HTTPS:
nginx
server {
listen 80;
server_name example.com;
return 301 https://$host$request_uri;
}

2、配置子域名:
nginx
server {
listen 80;
server_name sub.example.com;

location / {
root /var/www/sub.example.com;
index index.html index.htm;
}
}

3、配置通配符域名:
nginx
server {
listen 80;
server_name *.example.com;

location / {
root /var/www/wildcard;
index index.html index.htm;
}
}

配置完成后，记得测试并重新加载 Nginx:
bash
sudo nginx t 测试配置
sudo systemctl reload nginx 重新加载配置
