nginx https下不带www跳转www设置

Question

nginx版本

nginx version: nginx/1.10.2

已经实现了http://(www).airknow.com 跳转到 https://www.airknow.com，但是无法实现https://airknow.com 跳转到https://www.airknow.com 该怎么修改配置

以下是我配置

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

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

server {
    listen  443;
    server_name  www.airknow.com;
    ssl on;
    #...
}    

Answer 1

在写一个443端口 我是这样解决的 两个80端口可以合并成一个 server_name www.xxx.com xxx.com

Answer 2

我尝试过在上面第二个server和第三个server之间新加一个server

server {
    listen 443;
    server_name airknow.com
    return 301 https://www.airknow.com$request_uri;
}    

重启后https://airknow.com网站都访问不了。

Answer 3

跟你一样的问题，找到了答案

server {
    listen 443;
    server_name airknow.com
    return 301 https://www.airknow.com$request_uri;
}    

server {
    listen  443  default_server ssl;
    server_name  www.airknow.com;
   
}   

像上面这样，在第三个server的443后面加上default_server ssl，不知道会不会有什么负面影响
