From nginx's official documentation document, the correct nginx https 301 jumps to the www domain name method as follows:
HTTP 301 jumps to the domain name method with www
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 jumps to the domain name method with www
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...
}
}Check the version of nginx you are using with the nginx-v command first. Here's how to jump from nginx301 to www with the www.ksharpdabu.info to ksharpdabu.info for the older version
server {
server_name www.domain.com;
rewrite ^(.*) http://domain.com$1 permanent;
}
server {
server_name domain.com;
#The rest of your configuration goes here#
}
So you need two server segments.
Jump from ksharpdabu.info to 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#
}
After the above Settings, jump to the specified domain name with the method of rewrite, which is conducive to SEO
Here is my example of the nginx configuration from www.google.com to google.com:
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;
}
}
There is another way to avoid rewirte online, as follows:
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...
}
Because return can be used in all versions, while rewrite can cause 301 errors depending on the version. And you can simply stop performing matches and searches.
http and https are included below. Same server.
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...
}The $scheme variable will only contain http if your server only listens on port 80 (the default is port 80) and the ssl keyword is not included in the option to listen at the same time. Without this variable, you will not get the jump results you want.
Force all http to jump to https, SSL (personal config on UNIX with IPv4, IPv6, SPDY...) :
#
# Redirect all www to non-www
#
server {
server_name www.example.com;
ssl_certificate ssl/example.com/crt;
ssl_certificate_key ssl/example.com/key;
listen *:80;
listen *:443 ssl spdy;
listen [::]:80 ipv6only=on;
listen [::]:443 ssl spdy ipv6only=on;
return 301 https://example.com$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...
}
