Konfigurowanie pojedynczej instancji Zookeepera i niepowodzenie wiązania

Question

Próbuję skonfigurować pojedynczą instancję zookeepera, korzystając z poniższej konfiguracji, jednak dziennik startowy wskazuje, że zookeeper zatrzymuje się podczas próby wiązania portu 2181. Może ktoś, proszę, proszę daj mi znać tutaj. Dziękuję Ci.

Answer 1

chciałbym wspomnieć, że gdy pojawi się następujący komunikat logowania oznacza to, że serwer jest rzeczywiście zaczęło.

INFO [main:NIOServerCnxnFactory@94] - binding to port 0.0.0.0/0.0.0.0:2181 

także komunikat o błędzie, który widzisz, jeśli masz jedno wystąpienie Heca jak poniżej jest faktycznie ostrzeżenie zamiast błędu.

2014-07-18 16:00:48,980 [myid:] - ERROR [main:QuorumPeerConfig@289] - Invalid configuration, only one server specified (ignoring) 

Answer 2

Proponuję usunąć następującą linię z pliku konfiguracyjnego

server.1=localhost:2888:3888 

a następnie zrestartować serwer.

Answer 3

Czy używasz zookeepera w 64-bitowym systemie Windows. Miałem ten sam problem, ale potem zorientowałem się, że Win64 nie jest obsługiwany. Patrz odnośnik Heca http://zookeeper.apache.org/doc/r3.4.5/zookeeperAdmin.html#sc_supportedPlatforms

Answer 4

warto dodać to do zoo.cfg quorumListenOnAllIPs=true
