Question

我有两台服务器，一台服务器运行apache zookeeper，服务器二运行Solr。当启动zookeeper时，我可以在服务器1上连接它（通过bin / zkCli.sh），但不能通过服务器2连接到solr。 Zookeeper是通过supervisor启动的，但我也试过通过bind/zkServer.sh启动它而没有任何改进。当查看tomcat日志（Solr正在登录）时，我得到：

如何设置zookeeper，以便服务器2上的solr可以访问它？

其他信息：在服务器1上使用netstat -l，我得到以下信息：

tcp6       0      0 [::]:2181               [::]:*                  LISTEN

即。它只是监听tcp6，而不是tcp。

Answer 1

检查zookeeper服务器上的防火墙配置，确保端口2181,2888和3888全部打开。 2181是客户端通信端口，2888和3888用于zookeeper集群通信（如果您决定在集合中运行zookeeper）。

Solr关闭与Zookeeper的连接
