Question

这是一个很好的nginx配置吗？我是否正确地使用了301重定向（我有多个域名并希望所有域名都指向https://domain.ru），并且我没有搞砸了他未来的所有搜索引擎优化？它将成为使用nginx，percona和php-fpm的1-2个wordpress网站的服务器

    server {
    listen 80;
    listen [::]:80;
    return 301 https://domain.ru$request_uri;
    server_name domain.com www.domain.com домен-домен.рф www.домен-домен.рф домен.рф www.домен.рф www.domain.ru domain.ru;
}

server {
        listen 443 ssl;
        listen [::]:443 ssl;
        ssl on;
        ssl_certificate /etc/ssl/12345.crt;
        ssl_certificate_key /etc/ssl/12345.key;
    server_name www.domain.ru;
    return 301 https://domain.ru$request_uri;
}

server {
        listen 443 ssl;
        listen [::]:443 ssl;
        ssl on;
        ssl_certificate /etc/ssl/12345.crt;
        ssl_certificate_key /etc/ssl/12345.key;

        root /var/www/html;

        index index.html index.php index.htm index.nginx-debian.html;

        server_name domain.ru;

        gzip on;
        gzip_disable "msie6";
        gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript;
