Zookeeper單機和集群安裝

目錄

單機版安裝

修改配置檔案

啟動、檢視，停止zookeeper服務

集群zk服務配置和啟動

準備多個zookeeper服務目錄

建立並配置myid檔案 

編輯zoo.cfg檔案配置zk集群資訊

按myid從小到大的順序依次啟動每個zookeeper服務

檢視集群中每個服務的角色

apache-zookeeper-3.6.1-bin.tar.gz

apache-zookeeper-3.6.1-bin.tar.gz

而不是

apache-zookeeper-3.6.1.tar.gz

，不帶bin的包需要手動mvn打包才能啟動

[root@host-192-168-48-4 apache-zookeeper-3.6.1-bin]# ls

bin conf docs lib license.txt notice.txt readme.md readme_packaging.md

[root@host-192-168-48-4 apache-zookeeper-3.6.1]# cd conf/

[root@host-192-168-48-4 conf]# ls
configuration.xsl log4j.properties zoo_sample.cfg

[root@host-192-168-48-4 conf]# mv zoo_sample.cfg zoo.cfg

進入bin目錄下，可以看到可執行的指令碼

[root@host-192-168-48-4 bin]# ls

readme.txt zkcli.cmd zkenv.cmd zkserver.cmd zkserver.sh zksnapshottoolkit.sh zktxnlogtoolkit.sh
zkcleanup.sh zkcli.sh zkenv.sh zkserver-initialize.sh zksnapshottoolkit.cmd zktxnlogtoolkit.cmd

./zkserver.sh start

[root@host-192-168-48-4 bin]# ./zkserver.sh start

zookeeper jmx enabled by default
using config: /opt/fkk/apache-zookeeper-3.6.1/bin/../conf/zoo.cfg

[root@host-192-168-48-4 bin]# ./zkserver.sh status

[root@host-192-168-48-4 fkk]# cp -r apache-zookeeper-3.6.1-bin/ zookeeper01

[root@host-192-168-48-4 fkk]# cp -r apache-zookeeper-3.6.1-bin/ zookeeper02
[root@host-192-168-48-4 fkk]# cp -r apache-zookeeper-3.6.1-bin/ zookeeper03
[root@host-192-168-48-4 fkk]# ls
zookeeper02 zookeeper03 zookeeper01 apache-zookeeper-3.6.1-bin

編輯每個zk服務目錄下的conf下的zoo.cfg檔案，在檔案末尾新增要搭建的集群的所有的服務的通訊資訊列表。

格式：

集群中有幾個zk服務節點，就要寫幾條資訊記錄，例如有三個zk服務節點那資訊列表就是三條記錄，如下

server.1=127.0.0.1:2881:3881

server.2=127.0.0.1:2882:3882
server.3=127.0.0.1:2883:3883

也就是按剛剛建立的myid檔案中的值大小依次啟動對應的zk服務，這樣就完成了乙個集群的啟動

[root@host-192-168-48-4 fkk]# zookeeper01/bin/zkserver.sh start

zookeeper jmx enabled by default
using config: /opt/fkk/zookeeper01/bin/../conf/zoo.cfg
starting zookeeper ... started
[root@host-192-168-48-4 fkk]# zookeeper02/bin/zkserver.sh start
zookeeper jmx enabled by default
using config: /opt/fkk/zookeeper02/bin/../conf/zoo.cfg
starting zookeeper ... started
[root@host-192-168-48-4 fkk]# zookeeper03/bin/zkserver.sh start
zookeeper jmx enabled by default
using config: /opt/fkk/zookeeper03/bin/../conf/zoo.cfg
starting zookeeper ... started
