standalone适合开发，因为是单机，因此不能作为产品环境使用。先准备三台Ubuntu虚拟机，IP地址分别为：
192.168.1.70 zka 192.168.1.71 zkb 192.168.1.72 zkc
然后在zoo.cfg文件中如下配置，三台相同：
# The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=/opt/zk_data # the port at which the clients will connect clientPort=2181 # the maximum number of client connections. # increase this if you need to handle more clients maxClientCnxns=60 # # Be sure to read the maintenance section of the # administrator guide before turning on autopurge. # # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # The number of snapshots to retain in dataDir #autopurge.snapRetainCount=3 # Purge task interval in hours # Set to "0" to disable auto purge feature #autopurge.purgeInterval=1 server.1=zka:2888:3888 server.2=zkb:2888:3888 server.3=zkc:2888:3888
注意最下面三行，zka/zkb/zkc是hostname，因为前面在hosts都已经配置了相应的IP地址，因此不会找不到主机。
2888端口是zookeeper服务相互通信使用的，3888端口是zookeeper服务选举使用的。
server.后面的1,2和3需要做些配置，在每台服务器的dataDir目录下(我这里是/opt/zk_data)，创建myid文件，里面包含对应的1，2和3.
然后分别启动三台服务器上的zookeeper server。
bin/zkServer.sh start
由于我没有设置日志目录，所以可以看一下默认日志文件zookeeper.out, 没有错误，一切正常。
