Zookeeper - 三个节点，只有错误

问题描述：

我有三个zookeeper节点.所有端口都是开放的.ip地址是正确的.下面是我的配置文件.所有由 Chef 启动的节点都具有相同的安装和配置文件.

I have three zookeeper nodes. All ports are open. The ip address are correct. Below is my config file. All nodes where booted by chef and all have the same install and config file.

# The number of milliseconds of each tick
tickTime=3000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
dataDir=/var/lib/zookeeper
# Place the dataLogDir to a separate physical disc for better performance
# dataLogDir=/disk2/zookeeper

# the port at which the clients will connect
clientPort=2181

server.1=111.111.111:2888:3888
server.2=111.111.112:2888:3888
server.3=111.111.113:2888:3888

这是其中一个节点的错误.所以......我对如何得到错误感到很困惑，因为配置相当普通.所有三个节点都在做同样的事情.

Here is error for one of the nodes. So...I am rather confused on how I could get an error since the config is rather vanilla. All three nodes are doing hte same thing.

答

您需要创建一个名为 myid 的文件并将其放入 zookeeper var 目录，每个服务器一个，由一行仅包含该机器的 id 文本组成.所以服务器 1 的 myid 将包含文本1"而没有其他内容.id 在集合中必须是唯一的，并且值应该在 1 到 255 之间.

You need create a file named myid and put it into zookeeper var directory, one for each server, consists of a single line containing only the text of that machine's id. So myid of server 1 would contain the text "1" and nothing else. The id must be unique within the ensemble and should have a value between 1 and 255.
