首先准备三个节点
192.168.1.127
192.168.1.128
192.168.1.129
先安装zookeeper
cd /usr/local/src/
wget http://apache.fayea.com/zookeeper/zookeeper-3.5.1-alpha/zookeeper-3.5.1-alpha.tar.gz
tar zxf zookeeper-3.5.1-alpha.tar.gz
mv zookeeper-3.5.1-alpha /usr/local/zookeeper
更改三个节点配置
server.1=192.168.1.127:2008:6008
server.服务器编··=服务器地址:LF通信端口:选举端口
cd /usr/local/zookeeper && mkdir -p /data/zookeeper
vim conf/zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper
clientPort=2181
server.1=192.168.1.127:2008:6008
server.2=192.168.1.128:2008:6008
server.3=192.168.1.129:2008:6008
启动前两个节··
./bin/zkServer.sh start
ZooKeeper JMX enabled by default
/usr/bin/java
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
你会发现有报错是因为其他节点没有起来
