Neo4j 嵌入式：从 2.3.9 升级到 3.2.3：initial_hosts 没有相互通信
Neo4j embedded : Upgrade from 2.3.9 to 3.2.3 : initial_hosts are not communicating with each other
我已经在 SINGLE 模式下将我的 neo4j 嵌入式数据库从 2.3.9 升级到 3.2.3，它已成功升级。升级后，我启用了 "HA" 模式。虽然 运行 neo4j 有 3 个集群，但我面临以下问题。
个别服务器 运行 在 HA 模式下没问题。 （即 ha.initial_hosts = "ip_address_1:5101"），但如果我在 initial_hosts 下添加三台服务器（如配置所示），所有三台服务器都会立即停止。
我是否缺少任何配置？请提出建议。
配置：
neo4j {
# Enable these two options while upgrading neo4j database.
# dbms.allow_format_migration=true
# or weak or strong
cache_type = "weak"
# Reduce the default page cache memory allocation
dbms.memory.pagecache.size="6G"
# Port to listen to for incoming backup requests.
dbms.backup.address = ${local.private-ip}":6367"

# can not be negative id and must be unique
