4. 配置

1>进入解压过后的zookeeper/conf目录

[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>将zoo_sample.cfg文件复制为zoo.cfg，因为配置伪分布式所以复制三份

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

3>编辑zoo1.cfg文件

[root@lingyun conf]# vi zoo1.cfg

修改zoo2.cfg

vi zoo2.cfg

修改zoo3.cfg

vi zoo3.cfg

4> 创建zookeeper 保存数据的文件

[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)

分别在以上路径下新建myid文件

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

写入内容

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

启动

[root@lingyun zookeeper]# ls
bin  conf  data  docs  lib  LICENSE.txt  NOTICE.txt  README.md  README_packaging.txt
[root@lingyun zookeeper]# bin/zkServer.sh start zoo1.cfg
