怎样将zookeeper的mode由standalone改成集群形式'

怎样将zookeeper的mode由standalone改成集群形式'

将下载的 ZooKeeper 解压，进入 conf 目录，复制一份 zoo_sample.cfg 的配置文件命名为 zoo.cfg，修改如下：

　　# the basic time unit in milliseconds used by ZooKeeper. It is used to do heartbeats
tickTime=2000
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/var/lib/zookeeper
# the port at which the clients will connect
clientPort=2181

　　2、 进入 bin 目录，启动 ZooKeeper：
　　./zkServer.sh start

　　启动运行后会创建相关目录，所以注意相关目录的写权限。启动的日志如下：
　　ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.9/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

　　3、 Client Connecting to ZooKeeper
　　客户端连接到 ZooKeeper：
　　./zkCli.sh -server 127.0.0.1:2181

　　连接成功的日志输出：
　　Welcome to ZooKeeper!

SendThread(127.0.0.1:2181):ClientCnxn$SendThread@1032] - Opening socket connection to server 127.0.0.1/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)

WATCHER::

肯定是环境的配置那里有问题，仔细找找。我的是集群zoo.cfg放在的根目录下，而单机的zoo.cfg放在了/conf目录下。所以一直显示是standalone状态。
