本文详细介绍了如何从官网下载并配置Apache Zookeeper 3.5.10，包括设置心跳时间、通信限制和数据目录，以及启动服务的过程。重点在于配置文件的调整和启动zookeeper服务的步骤。

【安装 zookeeper-3.5.10】

# wget https://archive.apache.org/dist/zookeeper/zookeeper-3.5.10/apache-zookeeper-3.5.10-bin.tar.gz
# tar -zxvf apache-zookeeper-3.5.10-bin.tar.gz
# mv apache-zookeeper-3.5.10-bin /opt/soft/apache-zookeeper-3.5.10
# 创建zk数据目录：
# mkdir -p /opt/soft/zookeeper/zkdata
# cd /opt/soft/apache-zookeeper-3.5.10/conf/
# cp zoo_sample.cfg zoo.cfg
# vim zoo.cfg

配置如下内容：

# 通信心跳时间，Zookeeper 服务器与客户端心跳时间，单位毫秒(ms)
tickTime=2000

# LF 初始通信时限。
# Leader 和 Follower 初始连接时能容忍的最多心跳数，单位是次(即tickTime的数量)
initLimit=10

# L/F 同步通信时限
# Leader 和 Follower 连接之后，通信时能容忍的最多心跳数，单位：次
# 时间如果超过 syncLimit * tickTime，Leader 认为 Follower 挂掉了，就会从服务器列表中删除改 Follower.
syncLimit=5

# dataDir：保存Zookeeper中的数据的目录.
dataDir=/opt/soft/zookeeper/zkdata
dataLogDir=/opt/soft/zookeeper/zklogs

# 客户端连接端口，通常不会修改
clientPort=2181

# 启动zookeeper服务
# cd /opt/soft/apache-zookeeper-3.5.10
# ./bin/zkServer.sh start

[root@VM-xxx-centos apache-zookeeper-3.5.10]# ./bin/zkServer.sh start
