zookeeper单机安装

2018年5月19日 作者 jacky

1.下载zookeeper:

wget http://apache.fayea.com/zookeeper/stable/zookeeper-3.4.6.tar.gz

2.解压

tar zxvf zookeeper-3.4.6.tar.gz

3.配置

进入配置文件夹,将zoo_sample.cfd文件名称改为zoo.cfg, 缺省的配置内容如下

# 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=/tmp/zookeeper
# 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

配置说明:

tickTime:这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔,也就是每个 tickTime 时间就会发送一个心跳。

dataDir:顾名思义就是 Zookeeper 保存数据的目录,默认情况下,Zookeeper 将写数据的日志文件也保存在这个目录里。

dataLogDir: log目录, 同样可以是任意目录. 如果没有设置该参数, 将使用和dataDir相同的设置。

clientPort:这个端口就是客户端连接 Zookeeper 服务器的端口,Zookeeper 会监听这个端口,接受客户端的访问请求。

4、启动Zookeeper

当这些配置项配置好后,你现在就可以启动zookeeper了:

./zkServer.sh start #启动
netstat -tunlp|grep 2181 #查看zookeeper端口
./zkServer.sh stop #停止
