nginx 从 www 重写为非 www

nginx 从 www 重写为非 www

我的 nginx 文件无法归档，我不知道是怎么回事。我已成功从 http 重定向到 https。但我无法将 www 重定向到非 www 版本。我做错了什么？

server {
listen 80;
server_name example.com;
return 301 https://$server_name$request_uri;

location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
    root /home/sammy/myproject;
}

location / {
    include proxy_params;
    proxy_pass http://unix:/home/sammy/myproject/myproject.sock;
}
# added for let's encrypt
location /.well-known/ {
   root /home/sammy/myproject;
   allow all;
}
}
server {
# SSL configuration

listen 443 ssl http2 default_server;
listen [::]:443 ssl http2 default_server;
include snippets/ssl-example.com.conf;
include snippets/ssl-params.conf;

    location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
    root /home/myproject/myproject;
}

location / {
    include proxy_params;
    proxy_pass http://unix:/home/sammy/myproject/myproject.sock;
}
# added for let's encrypt
location /.well-known/ {
   root /home/sammy/myproject;
   allow all;
}
}

我尝试了这个额外的块：

server {
listen 80;
server_name www.example.com;
return 301 https://$server_name$request_uri;
...
}

但这似乎不起作用。我想也许我应该将其更改为监听 443，但不确定这会如何影响 ssl 服务器块和 default_server 指令？

答案1

指$server_name的是您在虚拟主机块中定义的服务器名称。因此，您的附加块会导致重定向循环重定向回其自身。

您必须在那里使用文字域名而不是变量。

对于带有的 SSL 域www，您必须添加listen 443 ssl;到块和证书值。

因此，这应该是你的第三个区块：

server {
    listen 80;
    listen 443 ssl;
    server_name www.example.com;
    return 301 https://example.com$request_uri;
    include snippets/ssl-example.com.conf;
    include snippets/ssl-params.conf;
    ...
}

以下是我从 http 到 https 的转发方法。关键部分是底部的三个服务器块。

server {
  server_name www.example.com;

  listen 443 ssl http2;

  ssl_certificate /var/lib/acme/certs/***CERT_DIRECTORY/fullchain;
  ssl_certificate_key /var/lib/acme/certs/***CERT_DIRECTORY/privkey;

  # Set up preferred protocols and ciphers. TLS1.2 is required for HTTP/2
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;
  ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:!ADH:!AECDH:!MD5;

  # This is a cache for SSL connections
  ssl_session_cache shared:SSL:2m;
  ssl_session_timeout 60m;

  root     /var/www/***rootdir;

  # First line is a cached access log, second logs immediately
  access_log  /var/log/nginx/mrwild.access.log main buffer=32k flush=1m if=$log_ua;
  # access_log  /var/log/nginx/mrwild.access.log main;

  # Default location to serve
  location / {
    log_not_found off;

    # This is a static site, so set the cache control headers to allow caching
    # for a day  
    add_header Cache-Control "public";
    expires 1d;

    valid_referers none blocked server_names ~($host) ~(googleusercontent|google|bing|yahoo);
    if ($invalid_referer) {
      rewrite (.*) /stop-stealing-images.png redirect;
    }
  }
  # Let the hotlink detection image be hotlinked
  # *** Find yourself a suitable graphic
  location = /stop-stealing-images.png { 
    add_header Cache-Control "public"; expires 4h;
  }

  # Don't log robots errors but log access
  location = /robots.txt {
    allow all; log_not_found off; 
  }

  location ~ /favicon.ico {
    access_log off; log_not_found off;
  }

  # This is for issuing certificates
  location /.well-known/acme-challenge/ {
    root /var/www/acme-challenge/;
  }

}

# This server simply redirects the requested to the https version of the page
server {
  listen 80;
  server_name example.com;
  return 301 https://www.example.com$request_uri;
}

server {
  listen 80;
  server_name www.example.com;
  return 301 https://www.example.com$request_uri;
}

server {
  listen 443 ssl http2;
  server_name example.com;

  ssl_certificate /var/lib/acme/certs/***CERT_DIRECTORY/fullchain;
  ssl_certificate_key /var/lib/acme/certs/***CERT_DIRECTORY/privkey;

  # Set up preferred protocols and ciphers. TLS1.2 is required for HTTP/2
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;
  ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:!ADH:!AECDH:!MD5;

  access_log  /var/log/nginx/mrwild.access.log main buffer=32k flush=1m if=$log_ua;

  return 301 https://www.example.com$request_uri;
}
