Zookeeper伪分布式集群搭建

  • 描述

伪分布式集群就是在一台机器部署多个zk应用，部署之前服务器需要有jdk环境 java -version可以显示相关java信息才可以进行zookeeper搭建

二、步骤

第一步下载好zookeeper-3.4.9.tar.gz

然后解压tar zxvf zookeeper-3.4.9.tar.gz

进入zk中的conf目录下输入cp zoo-sample.cfg zoo1.cfg cp zoo-sample.cfg zoo2.cfg、cp zoo-sample.cfg zoo3.cfg

分别对zoo1、2、3文件进行编辑







# 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=/apps/servers/data/d_1

dataLogDir=/apps/servers/logs/logs_1

# the port at which the clients will connect

clientPort=2181

#不同zoo.cfg修改自己的属性和端口号

# 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=localhost:2187:2887

server.2=localhost:2188:2888

server.3=localhost:2189:2889

 

修改之后分别创建data目录和日志目录







mkdir /apps/servers/data/d_1

Mkdir /apps/servers/data/d_1

mkdir /apps/servers/data/d_1

 

mkdir /apps/servers/logs/logs_1

mkdir /apps/servers/logs/logs_1

mkdir /apps/servers/logs/logs_1

 

echo “1” > /apps/servers/data/d_1/myid

echo “2” >/apps/servers/data/d_2/myid

echo “3” >/apps/servers/data/d_3/myid

进入bin目录下输入命令 分别进行启动







zkServer.sh start ../conf/zoo1.cfg

zkServer.sh start ../conf/zoo2.cfg

zkServer.sh start ../conf/zoo3.cfg

 

通过命令检测是否成功：

注意防火墙和配置是否成功，这个是部署成功的关键







zkServer.sh status或者zkCli.sh -server localhost:2181, localhost:2182, localhost:2183 是否可以连接成功

如果不能连接上查看下错误日志.
