Nginx http重定向到https

301强制重定向

#注意  是加在 ssl cer 后面  ，加在 前面 可能当作 是 80的 不生效呢 
#4 blog 
    server {
        listen       80;
       # listen [::]:80 ipv6only=on default_server;
        listen 443 default ssl;
       #listen [::]:80;
       #ssl on;
        ssl_certificate /etc/letsencrypt/live/linuxchina.net/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/linuxchina.net/privkey.pem;

       server_name  linuxchina.net www.linuxchina.net;

 #by evan
    if ($scheme = http) {
           return 301 https://$server_name$request_uri;
    } 
 #by evan
    #    server_name  blog.linuxchina.net;
        charset utf-8;
          root /data/www/evan;
        index index.php index.html index.htm;



#简约格式 

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

server {
    listen 443;
    ...
}

my eg

server  {
	listen 80;
	listen [::]:80;
	#listen 443 ssl http2;
	#listen [::]:443 ssl http2;    
 
    server_name www.cai.net cai.net;

#     return 301 https://www.cai.net$request_uri;
    rewrite ^(.*)$ https://$host$1 permanent;
}

server {
	listen 443 ssl http2;
	listen [::]:443 ssl http2;    
#    listen 443 ssl;
    server_name www.cai.net cailu.net;

#    if ( $host = 'www.cai.net'  )  {
#        rewrite ^/(.*)$ https://www.cai.net/$1 permanent;
#    }
#这个是不写多了呢 
    if ( $host = 'cai.net'  )  {
        rewrite ^/(.*)$ https://www.cai.net/$1 permanent;
    }

不同域名之间跳转

server
{
    listen 80;
    listen 443 ssl;
    server_name               m.cailuw.com;
尽量加在 证书后面 尽量前
    return                    301 https://m.cailuw.net$request_uri;
}

host.com跳https:

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

www 跳转非 www

if ($host = 'www.xxx.com' ) {
	    rewrite ^/(.*)$ http://xxx.com/$1 permanent;
        }

rewrite方法good 2022

server {
	listen	192.168.1.111:80;
	server_name	test.com;
	
	rewrite ^(.*)$	https://$host$1	permanent;
}

 
 cat traits.d/enable-redirect-https.conf 
    if ($scheme !~ 'https') {
        rewrite ^(/.*)$ https://$host$1 permanent;
    }




    include traits.d/enable-php.conf;
    include traits.d/enable-linux.conf;
    include traits.d/enable-redirect-https.conf;
}
