小丸子学ZooKeeper系列之——部署ZooKeeper集群

1.安装配置jdk和zookeeper环境
[root@mha-6 ~]# cd /appbase/apps/
[root@mha-6 apps]# rz
[root@mha-6 apps]# tar xzvf jdk1.7.0_71.tar.gz
[root@mha-6 apps]# tar xzvf zookeeper-3.4.6.tar.gz
[root@mha-6 apps]# rm -f *.gz
[root@mha-6 apps]# ls
jdk1.7.0_71  zookeeper-3.4.6


2.配置zookeeper集群
2.1 创建zookkper用户
[root@mha-6 ~]# groupadd -g 601 middle
[root@mha-6 ~]# useradd -u 611  -g middle -d /appbase/users/zkpusr01 zkpusr01
[root@mha-6 ~]# echo oracle|passwd --stdin oracle

2.2 创建集群成员目录
[root@mha-6 bin]# su - zkpusr01
[zkpusr01@mha-6 ~]$ mkdir -p zookeeper/{zk28/zk-data,zk38/zk-data,zk48/zk-data}
[zkpusr01@mha-6 ~]$ cp -R /appbase/apps/zookeeper-3.4.6/* zookeeper/zk28/
[zkpusr01@mha-6 ~]$ cp -R /appbase/apps/zookeeper-3.4.6/* zookeeper/zk38/
[zkpusr01@mha-6 ~]$ cp -R /appbase/apps/zookeeper-3.4.6/* zookeeper/zk48/

2.3 修改zoo.cfg配置文件（所有成员都需配置，以成员zk28为例）
[zkpusr01@mha-6 ~]$ vi /appbase/users/zkpusr01/zookeeper/zk28/bin/zkEnv.sh
JAVA_HOME=/appbase/apps/jdk1.7.0_71
ZOOKEEPER_PREFIX=/appbase/users/zkpusr01/zookeeper/zk28
ZOOBINDIR=/appbase/users/zkpusr01/zookeeper/zk28/bin
ZOO_LOG_DIR=/appbase/users/zkpusr01/zookeeper/zk28/logs

[zkpusr01@mha-6 ~]$ vi zookeeper/zk28/conf/zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/appbase/users/zkpusr01/zookeeper/zk28/zk-data
clientPort=28181
server.1=192.168.28.202:28881:38881
server.2=192.168.28.202:28882:39882
server.3=192.168.28.202:28883:39883

[zkpusr01@mha-6 ~]$ echo 1 > zookeeper/zk28/zk-data/myid


3. 启动zookeeper成员
[zkpusr01@mha-6 ~]$ zookeeper/zk28/bin/zkServer.sh start
JMX enabled by default
Using config: /appbase/users/zkpusr01/zookeeper/zk28/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

[zkpusr01@mha-6 ~]$ zookeeper/zk38/bin/zkServer.sh start
JMX enabled by default
Using config: /appbase/users/zkpusr01/zookeeper/zk38/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

[zkpusr01@mha-6 ~]$ zookeeper/zk48/bin/zkServer.sh start
JMX enabled by default
Using config: /appbase/users/zkpusr01/zookeeper/zk48/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED


4. 验证集群是否正常
--开启三个终端
[zkpusr01@mha-6 ~]$ zookeeper/zk28/bin/zkCli.sh  -server 192.168.28.202:28181
[zk: 192.168.28.202:28181(CONNECTED) 0] ls /
[zookeeper]

[zkpusr01@mha-6 ~]$ zookeeper/zk38/bin/zkCli.sh -server 192.168.28.202:38181
[zk: 192.168.28.202:38181(CONNECTED) 0] ls /
[zookeeper]

[zkpusr01@mha-6 ~]$ zookeeper/zk48/bin/zkCli.sh  -server 192.168.28.202:48181
[zk: 192.168.28.202:48181(CONNECTED) 0] ls /
[zookeeper]

--在任意成员上执行创建节点操作
[zk: 192.168.28.202:38181(CONNECTED) 1] create /zkcluster zkdata
Created /zkcluster
[zk: 192.168.28.202:38181(CONNECTED) 2] ls /
[zkcluster, zookeeper]

--观察其他成员数据是否同步
[zk: 192.168.28.202:28181(CONNECTED) 3] ls /
[zkcluster, zookeeper]

[zk: 192.168.28.202:48181(CONNECTED) 1] ls /
[zkcluster, zookeeper]

至此zookeeper集群部署成功。
