Zookeeper 集群配置及启动

准备工作

1. 集群机器

192.168.8.2

192.168.8.6

192.168.8.11

2. 包

zookeeper-3.4.10.tar.gz

集群配置

1. 解压路径

192.168.8.2　　/data1/projectX/zookeeper-3.4.10

192.168.8.6　　/data1/projectX/zookeeper-3.4.10

192.168.8.11　 /home/projectX/zookeeper-3.4.10

2. zoo.cnf

进入conf/ 目录，新建zoo.cnf文件，内容如下。（确保 dataDir 及 dataLogDir 所指向的路径已经存在）

192.168.8.2

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data1/projectX/zookeeper-3.4.10/data
dataLogDir=/data1/projectX/zookeeper-3.4.10/data/log
clientPort=2182
server.82=192.168.8.2:2887:3887
server.86=192.168.8.6:2887:3887
server.811=192.168.8.11:2887:3887
#maxClientCnxns=60
#autopurge.snapRetainCount=3
#autopurge.purgeInterval=1

192.168.8.6

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data1/projectX/zookeeper-3.4.10/data
dataLogDir=/data1/projectX/zookeeper-3.4.10/data/log
clientPort=2182
server.82=192.168.8.2:2887:3887
server.86=192.168.8.6:2887:3887
server.811=192.168.8.11:2887:3887
#maxClientCnxns=60
#autopurge.snapRetainCount=3
#autopurge.purgeInterval=1

192.168.8.11

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/home/projectX/zookeeper-3.4.10/data
dataLogDir=/home/projectX/zookeeper-3.4.10/data/log
clientPort=2182
server.82=192.168.8.2:2887:3887
server.86=192.168.8.6:2887:3887
server.811=192.168.8.11:2887:3887
#maxClientCnxns=60
#autopurge.snapRetainCount=3
#autopurge.purgeInterval=1

3. server.x 的配置

在三个机器的dataDir路径下面新建myid文件，内容分别为82，86 及 811 与 zoo.cnf中的保持一致。

server.82=192.168.8.2:2887:3887
server.86=192.168.8.6:2887:3887
server.811=192.168.8.11:2887:3887

启动Zookeeper

执行下面的命令分别启动三个zookeeper，无所谓顺序。

[root@RH bin]# cd /data1/projectX/zookeeper-3.4.10/bin/
[root@RH bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /data1/projectX/zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@RH bin]# tail -f zookeeper.out 

查看运行状态

192.168.8.2

-bash-4.1# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data1/projectX/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: follower

 192.168.8.6

[root@RH bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data1/projectX/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: follower

 192.168.8.11 << 被推选为Leader，其他两个为follower

[root@RDHW02-RIS bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/projectX/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: leader

简单测试

-bash-4.1# ./zkCli.sh -server 192.168.8.11:2182
[zk: 192.168.8.11:2182(CONNECTED) 0] ls /
[zk: 192.168.8.11:2182(CONNECTED) 1] ls2 /
[zk: 192.168.8.11:2182(CONNECTED) 2] create /test helloworld
[zk: 192.168.8.11:2182(CONNECTED) 4] get /test
[zk: 192.168.8.11:2182(CONNECTED) 5] set /test newvalue
[zk: 192.168.8.11:2182(CONNECTED) 7] delete /test
