從nginx的官方文檔 documentation, 正確的nginx https 301跳轉(zhuǎn)到帶www域名方法的方法如下：
HTTP 301跳轉(zhuǎn)到帶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跳轉(zhuǎn)到帶www域名方法
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 命令檢查你所說使用的nginx的版本. 下面是對于舊版本的nginx301跳轉(zhuǎn)到帶www域名方法從www.ksharpdabu.info 跳轉(zhuǎn)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#
}
所以需要兩個server段。
從ksharpdabu.info 跳轉(zhuǎn)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#
}
按上面設(shè)置后，用rewrite的方法跳轉(zhuǎn)到指定的域名下，利于SEO
下面是我舉例，從www.google.com 跳轉(zhuǎn)到 google.com的部分nginx配置內(nèi)容:
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;
}
}
網(wǎng)上還有一種不用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...
}
因為return可以用于所有的版本，而rewrite可能因為版本的不同，導(dǎo)致301出錯。而且可以直接停止執(zhí)行匹配和搜索。
下面包含了http和https的。同一個服務(wù)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...
}
$scheme 變量只會包含http 如果你的服務(wù)器只監(jiān)聽80端口(默認(rèn)是80端口)同時監(jiān)聽的選項中不含ssl關(guān)鍵字 . 不適用這個變量，就不能獲得你所想的要的跳轉(zhuǎn)結(jié)果。
將所有http強制跳到https， SSL (personal config on UNIX with IPv4, IPv6, SPDY, ...):
#
# Redirect all www to non-www
#
server {
server_name www.example.com;
ssl_certificate ssl/example.com/crt;
ssl_certificate_key ssl/example.com/key;
listen *:80;
listen *:443 ssl spdy;
listen [::]:80 ipv6only=on;
listen [::]:443 ssl spdy ipv6only=on;
return 301 https://example.com$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...
}
