ZooKeeper伪分布式集群安装

    伪分布式集群：在一台Server中，启动多个ZooKeeper的实例。

上传并解压安装包

?

1 2 3

cd  /usr rz -by tar  xf zookeeper-3.4.6. tar .gz

创建实例配置文件

?

1 2 3 4

cd  zookeeper-3.4.6 /conf cp  zoo_sample.cfg zoo1.cfg cp  zoo_sample.cfg zoo2.cfg cp  zoo_sample.cfg zoo3.cfg

修改配置文件

    实例1的配置：

?

1 2 3 4 5 6 7 8 9 10 11

vi  zoo1.cfg   tickTime=2000 initLimit=10 syncLimit=5 dataDir= /tmp/zookeeper/d_1 clientPort=2181 dataLogDir= /usr/zookeeper-3 .4.6 /logs_1 server.1=localhost:2887:3887 server.2=localhost:2888:3888 server.3=localhost:2889:3889

     实例2的配置：

?

1 2 3 4 5 6 7 8 9 10 11

vi  zoo2.cfg   tickTime=2000 initLimit=10 syncLimit=5 dataDir= /tmp/zookeeper/d_2 clientPort=2182 dataLogDir= /usr/zookeeper-3 .4.6 /logs_2 server.1=localhost:2887:3887 server.2=localhost:2888:3888 server.3=localhost:2889:3889

     实例3的配置：

?

1 2 3 4 5 6 7 8 9 10 11

vi  zoo3.cfg   tickTime=2000 initLimit=10 syncLimit=5 dataDir= /tmp/zookeeper/d_3 clientPort=2183 dataLogDir= /usr/zookeeper-3 .4.6 /logs_3 server.1=localhost:2887:3887 server.2=localhost:2888:3888 server.3=localhost:2889:3889

准备启动环境

?

1 2 3 4 5 6 7 8 9 10 11

mkdir  /tmp/zookeeper/d_1 mkdir  /tmp/zookeeper/d_2 mkdir  /tmp/zookeeper/d_3   mkdir  /usr/zookeeper-3 .4.6 /logs_1 mkdir  /usr/zookeeper-3 .4.6 /logs_2 mkdir  /usr/zookeeper-3 .4.6 /logs_3   echo  "1"  >  /tmp/zookeeper/d_1/myid echo  "2"  >  /tmp/zookeeper/d_2/myid echo  "3"  >  /tmp/zookeeper/d_3/myid

启动集群

?

1 2 3

/usr/zookeeper-3 .4.6 /bin/zkServer .sh start zoo1.cfg /usr/zookeeper-3 .4.6 /bin/zkServer .sh start zoo2.cfg /usr/zookeeper-3 .4.6 /bin/zkServer .sh start zoo3.cfg

查看是否启动成功

?

1 2 3 4 5 6 7 8 9

jps   #看到类似下面的进程就表示3个实例均启动成功 13419 QuorumPeerMain 13460 QuorumPeerMain 13561 Jps 13392 QuorumPeerMain   #如果未成功启动，可以到zookeeper.out文件中查看启动失败的日志信息。

查看节点状态

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[root@localhost ~] # /usr/zookeeper-3.4.6/bin/zkServer.sh status zoo1.cfg JMX enabled by default Using config:  /usr/zookeeper-3 .4.6 /bin/ .. /conf/zoo1 .cfg Mode: follower [root@localhost ~] # /usr/zookeeper-3.4.6/bin/zkServer.sh status zoo2.cfg JMX enabled by default Using config:  /usr/zookeeper-3 .4.6 /bin/ .. /conf/zoo2 .cfg Mode: leader [root@localhost ~] # /usr/zookeeper-3.4.6/bin/zkServer.sh status zoo3.cfg JMX enabled by default Using config:  /usr/zookeeper-3 .4.6 /bin/ .. /conf/zoo3 .cfg Mode: follower   #发现实例2为leader,实例1和实例3均为follower

    至此，一个ZK的伪分布式集群搭建完毕。
