linux中安装单机版zookeeper集群服务

linux中安装单机版zookeeper集群服务

创建配置文件

首先在zookeeper安装目录下的conf目录下创建3个配置文件zoo1.cfg,zoo2.cfg,zoo2.cfg,这三个配置文件差不多，只是有一点微小的差别，我的目录是/opt/soft/zookeeper-3.4.12/conf

[root@localhost conf]# tree
.
├── configuration.xsl
├── log4j.properties
├── zoo1.cfg
├── zoo2.cfg
├── zoo3.cfg
├── zookeeper.out
└── zoo_sample.cfg

zoo1.cfg配置文件内容:

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/tmp/zookeeper/zoo1 #！！区别
clientPort=2181 # zk客户端连接的端口 #！！区别

# 这里我们配置了3个服务结点
server.1=localhost:2666:3666
server.2=localhost:2667:3667
server.3=localhost:2668:3668

zoo2.cfg配置文件内容:

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/tmp/zookeeper/zoo2 #！！区别
clientPort=2182 # zk客户端连接的端口 #！！区别

server.1=localhost:2666:3666
server.2=localhost:2667:3667
server.3=localhost:2668:3668

zoo3.cfg配置文件内容:

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/tmp/zookeeper/zoo3 #！！区别
clientPort=2183 # zk客户端连接的端口 #！！区别

server.1=localhost:2666:3666
server.2=localhost:2667:3667
server.3=localhost:2668:3668

三个配置文件最大的不同点就是dataDir属性和clientPort属性

给每个服务实例设置server ID

必须给每个zookeeper服务结点设置server id

[root@localhost conf]# echo 1 > /tmp/zookeeper/zoo1/myid
[root@localhost conf]# echo 2 > /tmp/zookeeper/zoo2/myid
[root@localhost conf]# echo 3 > /tmp/zookeeper/zoo3/myid

启动

[root@localhost bin]# ./zkServer.sh start ../conf/zoo1.cfg
[root@localhost bin]# ./zkServer.sh start ../conf/zoo2.cfg
[root@localhost bin]# ./zkServer.sh start ../conf/zoo3.cfg
[root@localhost bin]# jps
14273 Jps
14035 QuorumPeerMain
13925 QuorumPeerMain
14159 QuorumPeerMain

客户端连接

[root@localhost bin]# ./zkCli.sh -server localhost:2181,localhost:2182,localhost:2183

停止zookeeper服务

[root@localhost bin]# ./zkServer.sh stop ../conf/zoo1.cfg
[root@localhost bin]# ./zkServer.sh stop ../conf/zoo2.cfg
[root@localhost bin]# ./zkServer.sh stop ../conf/zoo3.cfg
[root@JARVICENAE-0A0A1881 bin]# jps
