Ruby on rails example.com重定向您的次数太多。错误\u太多\u重定向

我试图在Ubuntu 16.04上用Let's Encrypt保护Nginx

获取SSL证书之前的example.conf文件

server {
    server_name example.com www.example.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;

}

server {
    server_name example.com www.example.com ;
    # Tell Nginx and Passenger where your app's 'public' directory is
    root /var/www/backup/example.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/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.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 ($host = www.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    server_name example.com www.example.com ;
    listen 80;
    return 404; # managed by Certbot

}

工作正常

我尝试通过以下方式获取SSL证书：

sudo certbot --nginx -d example.com -d www.example.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://example.com and
https://www.example.com

获取SSL证书后的example.conf文件

server {
    server_name example.com www.example.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;

}

server {
    server_name example.com www.example.com ;
    # Tell Nginx and Passenger where your app's 'public' directory is
    root /var/www/backup/example.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/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.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 ($host = www.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    server_name example.com www.example.com ;
    listen 80;
    return 404; # managed by Certbot

}

正在重定向到太多次

example.com重定向您的次数太多。 错误\u太多\u重定向

为什么它重定向了太多次

第二个服务器块的用途是什么

server {
if ($host = www.example.com) {
    return 301 https://$host$request_uri;
} # managed by Certbot


if ($host = example.com) {
    return 301 https://$host$request_uri;
} # managed by Certbot


server_name example.com www.example.com ;
listen 80;
return 404; # managed by Certbot

 }

如何将所有重定向到

编辑1

将certibot托管代码移动到第二个服务器块已停止过多重定向问题。但我的网站又回到了HTTP而不是https

    server {
            server_name example.com www.example.com ;
            # Tell Nginx and Passenger where your app's 'public' directory is
            root /var/www/backup/example.com/public;
            # Turn on Passenger
            passenger_enabled on;
            rails_env development;
            passenger_ruby /usr/local/rvm/gems/ruby-2.5.6/wrappers/ruby;

        }
        server {

            listen 443 ssl; # managed by Certbot
            ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
            ssl_certificate_key /etc/letsencrypt/live/example.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
            if ($host = www.example.com) {
                return 301 https://$host$request_uri;
            } # managed by Certbot


            if ($host = example.com) {
                return 301 https://$host$request_uri;
            } # managed by Certbot


            server_name example.com www.example.com ;
            listen 80;
            return 404; # managed by Certbot

        }

试试这个：

server {
    server_name example.com www.example.com ;
    listen 80;
    listen 443 ssl;

    if ($scheme != "https") {
        return 301 https://www.example.com$request_uri;
    }

    if ($host = example.com) {
        return 301 https://www.example.com$request_uri;
    }

    # Tell Nginx and Passenger where your app's 'public' directory is
    root /var/www/backup/example.com/public;
    # Turn on Passenger
    passenger_enabled on;
    rails_env development;
    passenger_ruby /usr/local/rvm/gems/ruby-2.5.6/wrappers/ruby;

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.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

}

如果使用HTTP而不是HTTPS或主机为example.com，则应重定向到www.example.com

关于你的问题：

我不确定，也许你在ruby代码中也重定向了。EDIT1代码示例将永远重定向，因为它使用$host重定向

在用于HTTP的端口80上重定向流量的奇怪方式

在我的示例中，我修复了重定向到www.example.com而不是$host的问题

试试这个：

server {
    server_name example.com www.example.com ;
    listen 80;
    listen 443 ssl;

    if ($scheme != "https") {
        return 301 https://www.example.com$request_uri;
    }

    if ($host = example.com) {
        return 301 https://www.example.com$request_uri;
    }

    # Tell Nginx and Passenger where your app's 'public' directory is
    root /var/www/backup/example.com/public;
    # Turn on Passenger
    passenger_enabled on;
    rails_env development;
    passenger_ruby /usr/local/rvm/gems/ruby-2.5.6/wrappers/ruby;

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.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
