生产环境下Neo4j核心集群无法搭建且无法完成Leader选举

生产服务器上搭建Neo4j核心集群时，日志无报错信息，但集群无法完成Leader选举。以下是相关配置与日志信息：

1. Neo4j配置文件（neo4j.conf） #

dbms.mode=CORE
causal_clustering.minimum_core_cluster_size_at_formation=3
causal_clustering.minimum_core_cluster_size_at_runtime=3
causal_clustering.initial_discovery_members=localhost:5000,localhost:5001,localhost:5002
causal_clustering.discovery_listen_address=:5000
causal_clustering.transaction_listen_address=:6000
causal_clustering.raft_listen_address=:7000

2. netstat -tunlp 输出 #
