Zookeeper配置及集群搭建

单节点配置

1. zoo.cfg

# 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=/usr/local/apache-zookeeper/data
# 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

2. zkServer.sh start
3. zkServer.sh status

   

2181 为监听客户端链接端口号 Mode 表示为单节点配置

zk集群配置

首先分别准备三台机器ip分别为

机器IP	zk端口号
192.168.0.1	2181
192.168.0.2	2181
192.168.0.3	2181

每台机器分别zk目录的data目录建立myid文件，内容分别为1，2，3, 且配置文件均为以下内容

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/apache-zookeeper/data
clientPort=2181
server.1=192.168.0.1:2888:3888
server.2=192.168.0.2:2888:3888
server.3=192.168.0.3:2888:3888
复制代码

若所有启动后，查看状态为未成功，则尝试关闭防火墙

ufw disalbe
