Archivos de registro de Zookeeper de Support-bundle (almacenes)

Introducción

Este documento describe ZooKeeper, que es esencialmente un servicio centralizado para sistemas distribuidos a un almacén jerárquico de valor de clave. Se utiliza para proporcionar un servicio de configuración distribuida, un servicio de sincronización y un registro de nombres para grandes sistemas distribuidos. La arquitectura de ZooKeeper admite alta disponibilidad mediante servicios redundantes. Así, los clientes pueden preguntar a otro líder de ZooKeeper si el primero no responde. Los nodos ZooKeeper almacenan sus datos en un espacio de nombres jerárquico, al igual que un sistema de archivos o una estructura de datos de árbol. Los clientes pueden leer y escribir en los nodos y, de esta manera, tener un servicio de configuración compartido. ZooKeeper se puede ver como un sistema de transmisión atómica a través del cual se ordenan las actualizaciones por completo.

ZooKeeper ofrece estas características principales:

- Sistema fiable: el sistema es muy fiable porque sigue funcionando incluso si falla un nodo.

- Arquitectura sencilla: la arquitectura de ZooKeeper es bastante sencilla; utiliza un espacio de nombres jerárquico compartido, que ayuda en la coordinación de procesos.

- Procesamiento rápido: ZooKeeper es especialmente rápido para las cargas de trabajo que dominan la lectura.

- Escalable: el rendimiento de ZooKeeper se puede mejorar mediante la adición de nodos.

En HX, existe esta implementación específica:

- El Servicio llamado expositor gestiona el inicio/cierre del zookeeper.

- Los procesos dentro del clúster HX son clientes a Zookeeper y se comunican a través del puerto TCP 2181 ex storfs, stmgr, etc.

- Los sistemas con más de cinco nodos tendrán algunos nodos independientes. Los sistemas con cinco nodos o menos nunca deben tener un nodo independiente.

- El número mínimo de nodos necesarios para el quórum = N/2 +1.

Por ejemplo, para un clúster de tres nodos - N/2=1.5 Se redondeó a 1 +1 =2 (sólo se puede tolerar una falla de nodo)

Por ejemplo, para un clúster de cinco nodos - N/2=2.5 Se redondeó a 2 +1 =3 (sólo se pueden tolerar dos fallos de nodo)

Dado que sólo hace cinco nodos para un clúster ZK, sólo tolera un máximo de dos fallas de nodo para cualquier número de nodos en el clúster. Esto es válido para los nodos convergentes.

Servicio Zookeeper de consulta

Zookeeper tiene una sintaxis de comandos de cuatro letras que le permite consultar el estado, las conexiones de lista, el número de nodos, etc.

Comprobar el estado del zookeeper en el nodo local - (rok ==> ¿Está bien? imok=>Estoy bien).

Archivos de registro de Zookeeper en una configuración en directo

Si hay algún problema en los servicios Zookeeper, estos archivos de registro ayudarán a encontrar seguimientos:

- /var/log/zookeeper/zookeeper*: mantiene registros archivados, palabras clave de búsqueda útiles ADVERTENCIA, ERROR, Adiós, Líder, etc.

- /var/log/springpath/zk-*

- /var/log/springpath/exhibitor.log
