zookeeper-3.4.12集群搭建

解压zookeeper文件到指定目录，执行命令
tar -zvxf zookeeper-3.4.12.tar.gz
配置环境变量，

vim /etc/profile

source /etc/profile

#zookeeper
export ZOOKEEPER_HOME=/var/local/zookeeper-3.4.12
export PATH=$ZOOKEEPER_HOME/bin:$PATH

建立两个文件夹

mkdir /var/local/zookeeper-3.4.12/data;
mkdir /var/local/zookeeper-3.4.12/logs

cd  /var/local/zookeeper-3.4.12/conf/

拷贝配置文件zoo_sample.cfg 改名为zoo.cfg

cp zoo_sample.cfg zoo.cfg

修改配置文件

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/var/local/zookeeper-3.4.12/data
dataLogDir=/var/local/zookeeper-3.4.12/logs
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=0.0.0.0:2888:3888
server.2=192.168.1.101:2888:3888
server.3=192.168.1.102:2888:3888

将zoo.cfg拷贝到其他两台机器中

scp zoo.cfg [email protected]:/var/local/zookeeper-3.4.12/conf/
scp zoo.cfg [email protected]:/var/local/zookeeper-3.4.12/conf/

进入data目录，执行命令
echo 1 > myid
创建myid文件并输入值为1，依次在另外两台机器上执行同样的操作，myid的数值依次为2，3配置成功；
执行命令./zkServer.sh start分别启动三台机器；
./zkServer.sh status分别查看机器上zookeeper 状态
