不尝试使用SASL进行身份验证（未知错误）

Question

我正在尝试在ec2的两个实例上设置zookeeper。如这里和这里所示。我正在尝试运行zookeeper，但失败了，出现了一个错误：命令：bin/zkCli。sh-服务器本地主机：2181

动物园cfg as波纹管

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper
clientPort=2181
server.1=localhost:2888:3888
server.2=<My ec2 private IPs>:2889:3889

我还在两个ec2实例上创建了myId文件-/var/lib/zoomaster/myid

我还试图编辑/ect/hosts文件，但仍然面临相同的问题。还有，如何通过一个命令启动两个zookeeper实例？

注意：如果我尝试使用bin/zkCli.shstart命令，服务器将成功启动。

提前感谢！




Answer 1

当我忘记运行%ZOOKEEPER\u HOME%\bin\zkserver时，发生了此错误。cmd

通过运行，问题已得到解决。

Answer 2

这是暂时的错误，我一段时间后，它消失了：-

这是我zoo.confe::

Dir=../data
clientPort=2181
tickTime=2000
initLimit=5

Answer 3

查看zk日志zookeeper。如果存在连接限制错误，请将以下配置为zoo。cfg公司。

# the maximum number of client connections.
# increase this if you need to handle more clients
maxClientCnxns=60
