what used que example baeldung actuator java spring ubuntu spring-boot

java - used - La aplicación Spring Boot Actuator no se iniciará en Ubuntu VPS



spring boot admin microservices (2)

La respuesta aceptada no funcionó para mí. Entonces encontré esta respuesta que sí:

La aplicación Spring-boot no arranca al inicio dentro de la ventana acoplable

apt-get install haveged -y

Tengo un backend Java que utiliza Spring Boot Actuator pero no se iniciará en Digitalocean Ubuntu VPS. La misma aplicación funciona bien en mi Mac y en otra PC Ubuntu.

szabolcs@SmartUpProd:~/smartup$ java -Xmx1536m -jar build/libs/smartup-backend-0.1.0.jar

Comienza la inicialización pero se detiene en el mismo punto cada vez (sin excepción, simplemente se cuelga). Si trato de detenerlo en este punto con ^C , no recuperará la caparazón.

Este es el outoput:

localhost-startStop-1 intenta crear una nueva instancia de SecureRandom y está atascada tratando de leer datos de una fuente de entropía. Esto normalmente ocurre porque la fuente se ha agotado. La fuente de entropía predeterminada es /dev/random . Se lo conoce como fuente de bloqueo, ya que se bloqueará cuando se intente leer datos aleatorios y no haya ninguno disponible. Otra fuente en Linux es /dev/urandom . Su principal ventaja sobre /dev/random es que no bloquea. Existe cierto debate sobre si usar /dev/urandom hará que las cosas sean menos seguras. Este artículo puede ser de interés.

En resumen, usar /dev/urandom evitará el problema que está viendo, con el posible costo de una menor seguridad. Puede configurar la instancia incorporada de Tomcat de Spring Boot para usar /dev/urandom través de una propiedad del sistema:

-Djava.security.egd=file:/dev/./urandom
