zookeeper安装

一、单节点安装

1、下载解压

tar -zxvf zookeeper-3.4.6.tar.gz

2、创建配置文件

$ZOOKEEPER_HOME/conf/下创建zoo.cfg

配置

tickTime=2000
dataDir=/usr/local/soft/job/zookeeper-3.4.6/data
dataLogDir=/usr/local/soft/job/zookeeper-3.4.6/logs
clientPort=4180

data和logs目录需要手动创建，否则服务不能正常启动

客户端连接会报错：Will not attempt to authenticate using SASL

环境变量： 

ZOOKEEPER_HOME=/usr/local/soft/job/zookeeper-3.4.6
export ZOOKEEPER_HOME
export PATH=${PATH}:${ZOOKEEPER_HOME}/bin

3、启动

./zkServer.sh start

4、客户端连接

./zkCli.sh -server localhost:4180
Connecting to localhost:4180

二、为分布式安装

1、创建环境目录

[root@localhost zookeeper-3.4.6]# mkdir zk1

[root@localhost zookeeper-3.4.6]# mkdir zk2

[root@localhost zookeeper-3.4.6]# mkdir zk3

2、创建myid文件

[root@localhost zookeeper-3.4.6]# echo "1" > ./zk1/myid

[root@localhost zookeeper-3.4.6]# echo "2" > ./zk2/myid

[root@localhost zookeeper-3.4.6]# echo "3" > ./zk3/myid

3、分别修改配置文件

修改：dataDir,clientPort
增加：集群的实例，server.X，”X”表示每个目录中的myid的值

[root@localhost conf]# vi zk1.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/soft/job/zookeeper-3.4.6/zk1
clientPort=2181
server.1=192.168.137.105:2888:3888
server.2=192.168.137.105:2889:3889
server.3=192.168.137.105:2890:3890

[root@localhost conf]# vi zk2.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/soft/job/zookeeper-3.4.6/zk2
clientPort=2182
server.1=192.168.137.105:2888:3888
server.2=192.168.137.105:2889:3889
server.3=192.168.137.105:2890:3890

[root@localhost conf]# vi zk3.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/soft/job/zookeeper-3.4.6/zk3
clientPort=2183
server.1=192.168.137.105:2888:3888
server.2=192.168.137.105:2889:3889
server.3=192.168.137.105:2890:3890

4、启动

[root@localhost bin]# ./zkServer.sh start zk1.cfg

[root@localhost bin]# ./zkServer.sh start zk2.cfg

[root@localhost bin]# ./zkServer.sh start zk3.cfg

5、查看状态

[root@localhost bin]# jps
8130 Jps
7833 QuorumPeerMain
7805 QuorumPeerMain
7853 QuorumPeerMain

[root@localhost bin]# ./zkServer.sh status zk1.cfg
JMX enabled by default
Using config: /usr/local/soft/job/zookeeper-3.4.6/bin/../conf/zk1.cfg
Mode: follower
[root@localhost bin]# ./zkServer.sh status zk2.cfg
JMX enabled by default
Using config: /usr/local/soft/job/zookeeper-3.4.6/bin/../conf/zk2.cfg
Mode: leader
[root@localhost bin]# ./zkServer.sh status zk3.cfg
JMX enabled by default
Using config: /usr/local/soft/job/zookeeper-3.4.6/bin/../conf/zk3.cfg
Mode: follower

可以看到zk2是leader，zk1和zk3是follower

 三、分布式安装

1、创建myid文件

Data目录下创建myid

分别写1,2,3

2、修改配置文件

tickTime=2000
dataDir=/usr/local/soft/job/zookeeper-3.4.6/data
dataLogDir=/usr/local/soft/job/zookeeper-3.4.6/logs
clientPort=4180
initLimit=10
syncLimit=5
server.1=192.168.137.105:2888:3888
server.2=192.168.137.106:2888:3888
server.3=192.168.137.107:2888:3888

　　

3、启动

zkServer.sh start

　　

4、连接

zkCli.sh -server 192.168.137.107:4180

　　

5、查看状态

jps

　　

四、操作
