zookeeper集群部署

zookeeper依赖jdk,先安装jdk,然后解压安装包,修改每个节点上的id即可,因为集群会选举超过半数节点投票的节点为主节点,所以集群一般为奇数个节点,避免"势均力敌"的情况。

wget https://dlcdn.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz
tar -zxvf apache-zookeeper-3.6.3-bin.tar.gz   

cd apache-zookeeper-3.6.2-bin
cd conf/
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg

clientPort=2181
dataDir=/data01/MPP/zk/data
# 注意server.后面的数字是每个节点的id,要和data/myid中的值完全一致
server.1=192.168.129.101:2888:3888
server.2=192.168.129.102:2888:3888
server.3=192.168.129.103:2888:3888

sudo mkdir -p /data01/MPP/zk/data
sudo chown -R tydic:tydic /data01/MPP
sudo chmod -R 751 /data01/MPP/zk/data
