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
