zk创建集群

在单机环境下和创建集群。

需要注意的点：

• 配置数据文件myid 1/2/3 对应server.1/2/3
• 通过./zkCli.sh -server [ip]:[port]  检测集群是否创建成功

在zoo.cfg配置文件下最下方写上

# The number of milliseconds of each tick
tickTime=
# The number of ticks that the initial
# synchronization phase can take
initLimit=
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataLogDir=/usr/local/zookeeper01/logs      ############需要重新设置下，日志存放的地方
dataDir=/usr/local/zookeeper01/data         ############需要重新设置下，数据存放的地方
# the port at which the clients will connect
clientPort=
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=
#
# 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=
# Purge task interval in hours
# Set to "" to disable auto purge feature
#autopurge.purgeInterval=
server.=localhost::
server.=localhost::
server.=localhost::

但是注意，这个配置文件上面的   dataDir= /usr/local/zookeeper01/data

然后我们到dataDir对应的目录去创建一个myid的文件  内容是1

其他两个依次类推。

然后重启zkServer.sh restart
