安装ZooKeeper

安装zookeeper

 cd /usr/local/src
 wget http://apache.fayea.com/zookeeper/zookeeper-3.4.8/zookeeper-3.4.8.tar.gz

启动&测试

启动 server 端

     bin/zkServer.sh start

启动客户端，尝试创建、查询节点

     bin/zkCli.sh -server localhost:2181


    [zk: localhost:2181(CONNECTED) 3] create /test 1111
    Created /test
    [zk: localhost:2181(CONNECTED) 4] get /test
    1111
    cZxid = 0x2
    ctime = Thu Sep 01 08:59:24 CST 2016
    mZxid = 0x2
    mtime = Thu Sep 01 08:59:24 CST 2016
    pZxid = 0x2
    cversion = 0
    dataVersion = 0
    aclVersion = 0
    ephemeralOwner = 0x0

安装dubbo-admin

安装tomcat

yum install tomcat6
部署 dubbo-admin 代码
```
 mkdir /var/lib/tomcat6/webapps/ROOT/
 unzip dubbo-admin/target/dubbo-admin-2.5.3.war -d /var/lib/tomcat6/webapps/ROOT/
1

```
确认/var/lib/tomcat6/webapps/ROOT/WEB-INF/dubbo.properties 中ZooKeeper的地址是否正确。本例中，该配置无需修改。然后就可以启动tomcat了。
```
 /etc/init.d/tomcat6 restart
1
```
可以通过浏览器访问 dubbo-admin。
