ClientPort=2181

DataLogDir=/usr/local/zookeeper/zookeeper/zkdatalog

Server.1=master:2888:3888

Server.2=slave1:2888:3888

Server.3=slave2:2888:3888

4. Create two folders, zkdata and zkdatalog

In the directory of zookeeper, create two folders, zkdata and zkdatalog.

The zkdatalog folder is to specify the corresponding path for zookeeper to generate logs.

Set up the myid. Create a myid under the directory specified by the dataDir that we configured

File, which contains a number that identifies the current host, which is configured in the conf/zoo.cfg file
