ZOOKEEPER 环境搭建

# tar xvf zookeeper-3.4.6.tar.gz -C /opt/app

# cp zoo_sample.cfg zoo.cfg

[root@quan zookeeper-3.4.6]# mkdir -p /data/zookeeper/data
[root@quan zookeeper-3.4.6]# ln -s /data/zookeeper/data/ /opt/app/zookeeper-3.4.6/

[root@quan conf]# vim zoo.cfg
# 修改dataDir
dataDir=/opt/app/zookeeper-3.4.6/data/

# 添加dataLogDir 日志路径
dataLogDir=/opt/app/zookeeper-3.4.6/logs

# 配置三个节点 同时注意/etc/hosts配置

[root@quan zookeeper-3.4.6]# cd data/
[root@quan data]# ls
[root@quan data]# vim myid

[root@quan app]# scp -r zookeeper-3.4.6 root@server02:/opt/app
[root@quan app]# scp -r zookeeper-3.4.6 root@server03:/opt/app


分别将`server02`和`server03` data目录中 myid 文件修改为2/3
