dubbo 笔记四 Zookeeper配置

Zookeeper单机配置

 

<dubbo:registry address="zookeeper://10.20.153.10:2181" />

Or:

 

<dubbo:registryprotocol="zookeeper"address="10.20.153.10:2181"/>

 

Zookeeper集群配置:

<dubbo:registryaddress="zookeeper://10.20.153.10:2181?backup=10.20.153.11:2181,10.20.153.12:2181"/>

or：

<dubbo:registryprotocol="zookeeper"address="10.20.153.10:2181,10.20.153.11:2181,10.20.153.12:2181"/>

 

同一Zookeeper，分成多组注册中心:

 

<dubbo:registry id="chinaRegistry" protocol="zookeeper" address="10.20.153.10:2181" group="china" />

<dubbo:registry id="intlRegistry" protocol="zookeeper" address="10.20.153.10:2181" group="intl" />

 

 

Zookeeper注册中心安装：

安装：

wget http://www.apache.org/dist//zookeeper/zookeeper-3.3.3/zookeeper-3.3.3.tar.gz

tar zxvf zookeeper-3.3.3.tar.gz

cd zookeeper-3.3.3

cp conf/zoo_sample.cfg conf/zoo.cfg

 

配置:

vi conf/zoo.cfg

如果不需要集群，zoo.cfg的内容如下：(其中data目录需改成你真实输出目录)

 

tickTime=2000

initLimit=10

syncLimit=5

dataDir=/home/dubbo/zookeeper-3.3.3/data

clientPort=2181

 

如果需要集群，zoo.cfg的内容如下：(其中data目录和server地址需改成你真实部署机器的信息)

 

tickTime=2000

initLimit=10

syncLimit=5

dataDir=/home/dubbo/zookeeper-3.3.3/data

clientPort=2181

server.1=10.20.153.10:2555:3555

server.2=10.20.153.11:2555:3555

 

并在data目录下放置myid文件：(上面zoo.cfg中的dataDir)

mkdir data

 

vi myid

 

myid指明自己的id，对应上面zoo.cfg中server.后的数字，第一台的内容为1，第二台的内容为2，内容如下：

1

 

启动:

./bin/zkServer.sh start

停止:

./bin/zkServer.sh stop
