4. Configuration

1>Enter the decompressed zookeeper/conf directory

[root@lingyun tools]# cd apache-zookeeper-3.5.9-bin
[root@lingyun apache-zookeeper-3.5.9-bin]# cd conf
[root@lingyun conf]# ls
configuration.xsl  log4j.properties  zoo_sample.cfg

2> Copy the zoo_sample.cfg file as zoo.cfg, and copy three copies because of the pseudo-distributed configuration

[root@lingyun conf]# cp zoo_sample.cfg zoo.cfg

3> Edit the zoo1.cfg file

[root@lingyun conf]# vi zoo1.cfg

Modify zoo2.cfg

vi zoo2.cfg

4> Create a file for zookeeper to save data

[root@lingyun conf\]# mkdir -p /usr/tools/zookeeper/data/zk1
[root@lingyun conf\]# mkdir -p /usr/tools/zookeeper/data/zk2
[root@lingyun conf\]# mkdir -p /usr/tools/zookeeper/data/zk3](https://img-blog.csdnimg.cn/0524554c26834617a63d4a38257b9704.png)

Create a new myid file under the above paths respectively

[root@lingyun data]# touch zk1/myid
[root@lingyun data]# touch zk2/myid
[root@lingyun data]# touch zk3/myid

write content

[root@lingyun data]# echo "1" > zk1/myid
[root@lingyun data]# echo "2" > zk2/myid
[root@lingyun data]# echo "3" > zk3/myid

start up

[root@lingyun zookeeper]# ls
bin  conf  data  docs  lib  LICENSE.txt  NOTICE.txt  README.md  README_packaging.txt
