zookeeper 学习记录-配置详解
# The number of milliseconds of each tick, # 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。tickTime以毫秒为单位。session最小有效时间为tickTime*2 tickTime=2000 # The number of ticks that the initial # synchronization phase can take # 集群中的follower服务器(F)与leader服务器(L)之间初始连接时能容忍的最多心跳数（tickTime的数量），超过此数量没有回复会断开链接 initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement # 集群中的follower服务器与leader服务器之间请求和应答之间能容忍的最多心跳数（tickTime的数量） syncLimit=5 # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. # 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。不要使用/tmp目录 dataDir=/var/zookeeper # the port at which the clients will connect # 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。 clientPort=2181 # the maximum number of client connections. # increase this if you need to handle more clients # 最大客户端链接数量 maxClientCnxns=60 # 以下配置用于数据清理，开启之前务必阅读官方文档http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # 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 ## Metrics Providers # # https://prometheus.io Metrics Exporter #metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider #metricsProvider.httpPort=7000 #metricsProvider.exportJvmInfo=true # zookeeper集群配置项，server.1，server.2，server.3是zk集群节点；zoo1,zoo2,zoo3是主机名称；2888是主从通信端口；3888用来选举leader server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
