redirect - 为什么这个 nginx 服务器重定向到错误的域？

Question

为什么这个 nginx 服务器重定向到错误的域？我的 nginx webserver 有两个域要服务，server1.eu 和 server2.eu，为什么它们会相互干扰？当我设置新的“干净”服务器安装时，不会出现此行为，因此此服务器的设置有什么问题。

监听 IPv6 的 nginx 网络服务器优先于 IPv4 并干扰 SNI。删除服务器的测试揭示了 nginx 的行为。

删除除服务器 1 之外的所有服务器，启用 IPv4 和 IPv6，重新加载 nginx，然后激活服务器 2，只有一个 IPv4 监听器并再次重新加载 nginx。浏览到服务器 2 将使您最终到达服务器 1。看起来 nginx 会自动监听第一个添加的 IPv6。因此，交换激活顺序将切换路由。

找到/etc/nginx/{conf.d,sites-enabled} 给出

/etc/nginx/sites-enabled/server1.eu 
/etc/nginx/sites-enabled/server2.eu 

区域文件记录:

AAAA    server1.eu    directs to IPv6 address
A   server1.eu    directs to IPv4 address
AAAA    server2.eu  directs to IPv6 address
A server2.eu directs to IPv4 address

nginx服务器配置:

server {
    listen 80;
    listen [::]:80;
server_name server1.eu;
    return 301 https://www.server1.eu;
}
server {
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        ssl_certificate /etc/letsencrypt/live/server1.eu/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/server1.eu/privkey.pem;
        include snippets/ssl-params.conf;

        server_name www.server1.eu;
        root /var/www/server1.eu/webroot;
        index index.php index.html index.htm ;

        location / {
            try_files $uri $uri/ /index.php?$args;
        }

        location ~ \.php$ {
            include fastcgi.conf;
            fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        }
}

和

server {
    listen 80;
    listen [::]:80;
    server_name www.server2.eu;
    return 301 https://$server_name$request_uri;
}

server {
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
    ssl_certificate /etc/letsencrypt/live/server2.eu/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/server2.eu/privkey.pem;
    include snippets/ssl-params.conf;
    server_name www.server2.eu;
    root /var/www/server2.eu/webroot;
    index index.php index.html index.htm ;

        location / {
            try_files $uri $uri/ /index.php?$args;
        }

        location ~ \.php$ {
            include fastcgi.conf;
            fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        }
}

我已经修改了您的 Nginx 配置。

这应该有效:

服务器 1:

server {
        listen 443 default_server ssl http2;
        listen [::]:443 default_server ssl http2;

        root /var/www/server1.eu/webroot;
        index index.php index.html index.htm;

        server_name www.server1.eu;

        ssl_certificate /etc/letsencrypt/live/server1.eu/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/server1.eu/privkey.pem;

        location / {
                try_files $uri $uri.html $uri/ @extensionless-php;
                autoindex on;
        }

        location @extensionless-php {
            rewrite ^(.*)$ $1.php last;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;

        #       # With php-fpm (or other unix sockets):
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        }
}

server {
    listen 80;
    server_name www.server1.eu;
    return 301 https://$host$request_uri;
}

服务器 2:

server {
        listen 443 ssl http2;
        listen [::]:443 ssl http2;

        root /var/www/server2.eu/webroot;
        index index.php index.html index.htm;

        server_name www.server2.eu;

        ssl_certificate /etc/letsencrypt/live/server2.eu/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/server2.eu/privkey.pem;

        location / {
                try_files $uri $uri.html $uri/ @extensionless-php;
                autoindex on;
        }

        location @extensionless-php {
            rewrite ^(.*)$ $1.php last;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;

        #       # With php-fpm (or other unix sockets):
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        }
}

server {
    listen 80;
    server_name www.server2.eu;
    return 301 https://$host$request_uri;
}

注:

变化 default_server 导致 server1 是您的默认服务器。
