创建目录 

/usr/local/soft/tmp/zookeeper/data

/usr/local/soft/tmp/zookeeper/log

[root@m1 conf]# mkdir -p /usr/local/soft/tmp/zookeeper/log
[root@m1 conf]# mkdir -p /usr/local/soft/tmp/zookeeper/data

关闭防火墙

[root@m1 zookeeper-3.4.9]# chkconfig iptables off
[root@m1 zookeeper-3.4.9]# chkconfig iptables --list
iptables           0:off    1:off    2:off    3:off    4:off    5:off    6:off

复制文件到其他机器

[root@m1 soft]# scp -r ./zookeeper-3.4.9 root@s1:/usr/local/soft/
[root@m1 soft]# scp -r ./zookeeper-3.4.9 root@s2:/usr/local/soft/

分别创建对应服务id的myid文件

[root@m1 soft]# cd tmp/zookeeper/data/
[root@m1 data]# pwd
/usr/local/soft/tmp/zookeeper/data
[root@m1 data]# echo "1" >> ./myid

分别设置环境变量

[root@m1 data]# vi /etc/profile

export ZOOKEEPER_HOME=/usr/local/soft/zookeeper-3.4.9
export PATH=$PATH:$ZOOKEEPER_HOME/bin

[root@m1 data]# source /etc/profile

启动

[root@m1 data]# zkServer.sh start
