Plesk permite instalar certificados SSL\/TLS gratuitos de Let’s Encrypt mediante SSL It!<\/strong>. Antes de solicitar uno, compruebe que el dominio apunta al servidor; si la validaci\u00f3n no puede llegar al alojamiento, la emisi\u00f3n fallar\u00e1.<\/p>\n\n\n\n

Instalar el certificado<\/h2>\n\n\n\n

Entre en Plesk<\/a> y abra Sitios web y dominios<\/strong>.<\/p>\n\n\n\n

\"Sitios<\/figure>\n\n\n\n

Dentro del dominio, abra Certificados SSL\/TLS<\/strong>.<\/p>\n\n\n\n

\"Certificados<\/figure>\n\n\n\n

Seleccione la opci\u00f3n para instalar un certificado gratuito de Let’s Encrypt.<\/p>\n\n\n\n

\"Instalar<\/figure>\n\n\n\n

En la pantalla siguiente elija los nombres que deban quedar cubiertos por el certificado. El dominio principal debe estar incluido y, si la web usa www<\/code>, incluya tambi\u00e9n ese nombre. Plesk puede ofrecer adem\u00e1s protecci\u00f3n para Webmail, correo, alias o un certificado wildcard.<\/p>\n\n\n\n

\"Opciones<\/figure>\n\n\n\n

Si el correo est\u00e1 alojado en el mismo servidor, incluya sus nombres cuando Plesk muestre esa posibilidad. As\u00ed el cliente de correo podr\u00e1 validar correctamente el certificado siempre que se conecte con uno de esos nombres.<\/p>\n\n\n\n

Pulse Obtenerlo gratis<\/strong>, Instalar<\/strong> o la opci\u00f3n equivalente. Plesk har\u00e1 la validaci\u00f3n y asignar\u00e1 el certificado si todo es correcto.<\/p>\n\n\n\n

Wildcard y renovaci\u00f3n<\/h2>\n\n\n\n

Un wildcard cubre subdominios del tipo *.tudominio.com<\/code> y utiliza validaci\u00f3n DNS. No hace falta para una web que solo necesite el dominio, www<\/code> y los nombres habituales de correo.<\/p>\n\n\n\n

Cuando el DNS est\u00e1 en el propio Plesk, la validaci\u00f3n puede automatizarse. Con DNS externo puede ser necesario crear un TXT _acme-challenge<\/code>, y eso tambi\u00e9n puede afectar a las renovaciones posteriores.<\/p>\n\n\n\n

Plesk intenta renovar autom\u00e1ticamente los certificados de Let’s Encrypt antes de que caduquen. Para que pueda hacerlo, los nombres incluidos deben seguir resolviendo correctamente y la validaci\u00f3n no debe quedar bloqueada por DNS, proxy, CDN o firewall.<\/p>\n\n\n\n

Si falla la instalaci\u00f3n<\/h2>\n\n\n\n

Revise qu\u00e9 nombre ha fallado y compruebe su DNS. Si ha seleccionado www<\/code>, Webmail, correo o un alias, cada nombre debe apuntar donde corresponde. En un wildcard, compruebe el TXT solicitado por Let’s Encrypt.<\/p>\n\n\n\n

Si sigue fallando, abra un ticket e incluya el dominio y el mensaje de error completo que muestra Plesk.<\/p>\n","protected":false},"excerpt":{"rendered":"
