我正在尝试将www重定向到非www，但是它不起作用。我已经尝试过类似问题的各种答案，但都没有用。
我有使用certbot的3个域的SSL证书example.com，www.example.com并且admin.example.com。
这是我当前的配置，适用于非www和admin，但是www.example.com不起作用。
# HTTP - redirect all requests to HTTPS
server {
listen 80;
listen [::]:80;
return 301 https://$host$request_uri;
}
# Redirect to non-www
server {
server_name www.example.com;
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.se/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.se/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
return 301 https://example.com$request_uri;
}
# non-www
server {
server_name example.com;
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.se/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.se/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
# CMS
server {
server_name admin.example.com;
location / {
proxy_pass http://localhost:1337;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.se/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.se/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
我使用DigitalOcean，其中admin和非www都指向我的Droplet，而www.example.com的CNAME记录指向example.com（非www）。
首先，www.example.com和example.com应该在一个服务器块中。
其次，您需要在#non-www服务器配置博客中添加它
if ($host = 'www.example.com') {
return 301 https://example.com$request_uri;
}
第三，要将所有请求重定向到HTTPS，server_name必须在您的# HTTP - redirect all requests to HTTPS块中添加。
最后，您的NGINX配置文件将如下所示
# HTTP - redirect all requests to HTTPS
server {
server_name example.com www.example.com admin.example.com;
listen 80;
listen [::]:80;
return 301 https://$host$request_uri;
}
# non-www
server {
server_name example.com www.example.com;
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
if ($host = 'www.example.com') {
return 301 https://example.com$request_uri;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.se/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.se/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
# CMS
server {
server_name admin.example.com;
location / {
proxy_pass http://localhost:1337;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.se/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.se/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
更新NGINX配置文件后，重新启动NGINX：
$ sudo systemctl restart nginx
