问题：
我在Ubuntu 16.04上尝试使用let's Encrypt保护Nginx。
获取SSL证书之前的mydomain.conf文件
server {
server_name mydomain.com www.mydomian.com ;
# Tell Nginx and Passenger where your app's 'public' directory is
root /var/www/backup/mycode/public;
# Turn on Passenger
passenger_enabled on;
rails_env development;
passenger_ruby /usr/local/rvm/gems/ruby-2.5.6/wrappers/ruby;
}
http://mydomain.com/工作正常。
我尝试通过以下方法获取SSL证书
sudo certbot --nginx -d mydomain.com -d www.mydomain.com
结果是
Your existing certificate has been successfully renewed, and the new certificate
has been installed.
The new certificate covers the following domains: https://mydomain.com and
https://www.mydomain.com
获取SSL证书之后的mydomain.conf文件
server {
server_name mydomain.com www.mydomain.com ;
# Tell Nginx and Passenger where your app's 'public' directory is
root /var/www/backup/mydomain.com/public;
# Turn on Passenger
passenger_enabled on;
rails_env development;
passenger_ruby /usr/local/rvm/gems/ruby-2.5.6/wrappers/ruby;
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/mydomain.com/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
}
server {
if ($host = www.mydomain.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = mydomain.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
server_name mydomain.com www.mydomain.com ;
listen 80;
return 404; # managed by Certbot
}
http://mydomain.com/重定向到https://mydomain.com/太多次
mydomain.com redirected you too many times.
ERR_TOO_MANY_REDIRECTS
为什么它重定向太多次？
第二个服务器块的用途是什么？
server {
if ($host = www.mydomain.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = mydomain.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
server_name mydomain.com www.mydomain.com ;
listen 80;
return 404; # managed by Certbot
}
- 如何使所有重定向到https://www.mydomain.com/？
答案1：
你可以试试这个：
How to Fix Err too many Redirects。
这个解决方案是针对wordpress.com的，但可以修复你的问题。
希望这可以帮到你。
答案2：
这个块导致问题
server {
if ($host = www.mydomain.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = mydomain.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
server_name mydomain.com www.mydomain.com ;
listen 80;
return 404; # managed by Certbot
}
此服务器块将用户重定向到https，但是，它还会将https重定向到https，这会导致问题，你可以将它更改为：
server {
listen 80;
server_name mydomain.com www.mydomain.com;
return 301 https://mydomain.com$request_uri;
}
