Question

在使用2台计算机创建Neo4j HA群集时，在进行必要的更改并启动neo4j服务后，即使在neo4j服务器中禁用了安全性，也会在从属neo4j Web UI中弹出身份验证卡，询问用户名和密码。两个实例的属性文件。

要输入错误的密码，它会显示错误的无效用户名或密码，但会引发错误＆＃39; HTTP状态：500 - 服务器错误＆＃39;输入正确的密码。

console.log显示了不同的图片：

消息说的是，群集还没有准备好。

等待数据库变为可用并允许新的超时交易。等了2米。阻止的1个原因：高可用性成员国没有准备好。 org.neo4j.graphdb.TransactionFailureException：超时等待数据库变为可用并允许新的交易。等了2米。阻止的1个原因：高可用性成员国没有准备好。

您需要至少3台计算机的法定数量才能运行群集。
