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
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
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
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
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: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：
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。
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…
}$scheme 变量只会包含http 如果你的服务器只监听80端口(默认是80端口)同时监听的选项中不含ssl关键字 . 不适用这个变量，就不能获得你所想的要的跳转结果。
将所有http强制跳到https， SSL (personal config on UNIX with IPv4, IPv6, SPDY, …):
#
# Redirect all www to non-www
#
server {
server_name www.example.com;
ssl_certificate ssl/example.com/crt;
ssl_certificate_key ssl/example.com/key;
listen *:80;
listen *:443 ssl spdy;
listen [::]:80 ipv6only=on;
listen [::]:443 ssl spdy ipv6only=on;return 301 https://example.com$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…
