nginx 从 www 重写为非 www

Question

我的 nginx 文件没有文件失败，我不确定如何。我已经成功地从 http 重定向到 https 很好。但我无法让 www 重定向到非 www 版本。我究竟做错了什么？

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。我想也许我应该改变它来监听 443，但不确定这会如何影响 ssl 服务器块和 default_server 指令？

Answer 1

该$server_name是指你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;块和证书值。

所以，这应该是你的第三个块：

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;
    ...
}
