想了解Nginx服务器中HTTP 301跳转到带www的域名的方法的相关内容吗，在本文为您仔细讲解Nginx中HTTP 301跳转到带www域名的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：Nginx,跳转，下面大家一起来学习吧。

从nginx的官方文档 documentation, 正确的nginx https 301跳转到带www域名方法的方法如下：

HTTP 301跳转到带www域名方法

复制代码代码如下:

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

    server {
        listen       80;
        server_name www.example.org;
        ...
    }

HTTPS 301跳转到带www域名方法

复制代码代码如下:

   server {

            listen 80;

            server_name www.domain.com;

            // $scheme will get the http protocol

            // and 301 is best practice for tablet, phone, desktop and seo

            return 301 $scheme://domain.com$request_uri;

    }

    server {

            listen 80;

            server_name domain.com;

            // here goes the rest of your config file

            // example 

            location / {

                rewrite ^/cp/login?$ /cp/login.php last;

                // etc etc...

            }

    }

要先用 nginx -v 命令检查你所说使用的nginx的版本. 下面是对于旧版本的nginx301跳转到带www域名方法从www.ksharpdabu.info 跳转到 ksharpdabu.info

复制代码代码如下:

server {
        server_name www.domain.com;
        rewrite ^(.*) http://domain.com$1 permanent;
    }

    server {
        server_name domain.com;
        #The rest of your configuration goes here#
    }

所以需要两个server段。

从ksharpdabu.info 跳转到 www.ksharpdabu.info

复制代码代码如下:

server {
        server_name domain.com;
        rewrite ^(.*) http://www.domain.com$1 permanent;
    }

    server {
        server_name www.domain.com;
        #The rest of your configuration goes here#
    }

按上面设置后，用rewrite的方法跳转到指定的域名下，利于SEO
下面是我举例，从www.google.com 跳转到 google.com的部分nginx配置内容:

复制代码代码如下:

server {

        server_name  www.google.com;

        rewrite ^(.*) http://google.com$1 permanent;

    }

    server {

           listen 80;

           server_name google.com;

           index index.php index.html;

           ####

           # now pull the site from one directory #

           root /var/www/www.google.com/web;

           # done #

           location = /favicon.ico {

                    log_not_found off;

                    access_log off;

           }

    }

网上还有一种不用rewirte的方法，如下：

复制代码代码如下:

server {
        #listen 80 is default
        server_name www.example.com;
        return 301 $scheme://example.com$request_uri;
    }

    server {
        #listen 80 is default
        server_name example.com;
        ## here goes the rest of your conf...
    }

因为return可以用于所有的版本，而rewrite可能因为版本的不同，导致301出错。而且可以直接停止执行匹配和搜索。

下面包含了http和https的。同一个服务器。

复制代码代码如下:

server {
        listen 80;
        listen 443 ssl;
        server_name www.example.com;
        return 301 $scheme://example.com$request_uri;
    }

    server {
        listen 80;
        listen 443 ssl;
        server_name example.com;
        # rest goes here...
    }

$scheme 变量只会包含http 如果你的服务器只监听80端口(默认是80端口)同时监听的选项中不含ssl关键字 . 不适用这个变量，就不能获得你所想的要的跳转结果。

将所有http强制跳到https， SSL (personal config on UNIX with IPv4, IPv6, SPDY, ...):

复制代码代码如下:

#
# Redirect all www to non-www
#
server {
    server_name          www.example.com;
    ssl_certificate      ssl/example.com/crt;
    ssl_certificate_key ssl/example.com/key;
    listen               *:80;
    listen               *:443 ssl spdy;
    listen               [::]:80 ipv6only=on;
    listen               [::]:443 ssl spdy ipv6only=on;

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

#
# Redirect all non-encrypted to encrypted
#
server {
    server_name          example.com;
    listen               *:80;
    listen               [::]:80;

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

#
# There we go!
#
server {
    server_name          example.com;
    ssl_certificate      ssl/example.com/crt;
    ssl_certificate_key ssl/example.com/key;
    listen               *:443 ssl spdy;
    listen               [::]:443 ssl spdy;

    # rest goes here...
}

#
# Redirect all www to non-www
#
server {
    server_name          www.example.com;
    ssl_certificate      ssl/example.com/crt;
    ssl_certificate_key ssl/example.com/key;
    listen               *:80;
    listen               *:443 ssl spdy;
    listen               [::]:80 ipv6only=on;
    listen               [::]:443 ssl spdy ipv6only=on;

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

#
# Redirect all non-encrypted to encrypted
#
server {
    server_name          example.com;
    listen               *:80;
    listen               [::]:80;

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

#
# There we go!
#
server {
    server_name          example.com;
    ssl_certificate      ssl/example.com/crt;
    ssl_certificate_key ssl/example.com/key;
    listen               *:443 ssl spdy;
    listen               [::]:443 ssl spdy;

    # rest goes here...
}
