https方式nginx 代理tomcat访问不带www的域名301重定向跳转到www的域名帮助seo集中权重

比如我要把

http://gucanhui.com

http://www.gucanhui.com

跳转到https://www.gucanhui.com

用F12的network可以看到状态码301,一定不能是302

需要注意的是,只需要nginx开启ssl就行了,tomcat和nginx还是走http就行

所以证书配置,只需要在nginx上配置

配置http不带www的跳转到https带www的

server {
        listen       ;
        server_name  gucanhui.com;
        return        https://www.gucanhui.com$request_uri;
    }

然后http带www的跳转到https带www的

server {
        listen       ;
        server_name  www.gucanhui.com;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {

            return        https://www.gucanhui.com$request_uri;
        }

然后再443端口配置证书和跳转就行了

 # HTTPS server
    #
    server {
        listen        ssl;
        server_name  www.gucanhui.com;

         ssl_certificate     gucanhui.com.crt;
        ssl_certificate_key  gucanhui.com.key;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;

        location / {
            proxy_pass http://127.0.0.1:8080;
        }
    }
