Ubuntu 安装zookeeper
下载zookeeper Zookeeper下载
下载以后将文件迁移到/home/Hadoop/文件夹下面
hongdada@ubuntu:~/Downloads$ sudo mv zookeeper-3.4.9.tar.gz /home/Hadoop
tar -zxvf解压
hongdada@ubuntu:/home/Hadoop$ sudo tar -zxvf zookeeper-3.4.9.tar.gz
将文件夹zookeeper-3.4.9改成zookeeper
hongdada@ubuntu:/home/Hadoop$ sudo mv zookeeper-3.4.9 zookeeper
解压以后conf文件夹中创建zoo_sample.cfg的副本zoo.cfg
hongdada@ubuntu:/home/Hadoop$ cd zookeeper hongdada@ubuntu:/home/Hadoop/zookeeper$ cd conf hongdada@ubuntu:/home/Hadoop/zookeeper/conf$ mp zoo_sample.cfg zoo_cfg mp：未找到命令 hongdada@ubuntu:/home/Hadoop/zookeeper/conf$ cp zoo_sample.cfg zoo.cfg cp: 无法创建普通文件'zoo.cfg': 权限不够 hongdada@ubuntu:/home/Hadoop/zookeeper/conf$ sudo cp zoo_sample.cfg zoo.cfg hongdada@ubuntu:/home/Hadoop/zookeeper/conf$ sudo gedit zoo.cfg
原始的zoo.cfg：
# 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
修改为：
# 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=/home/Hadoop/zookeeper/data # 数据持久化路径 dataLogDir=/home/Hadoop/zookeeper/log #日志保存路径 server.1=192.168.1.203:2888:3888 # 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
说明：
syncLimit=5 # Leader与Follower之间的最大响应时间单位，响应超过syncLimit*tickTime，Leader认为Follwer死掉，从服务器列表中删除Follwer。 initLimit=10 # 投票选举新leader的初始化时间。 tickTime=2000 # Zookeeper服务器心跳时间，单位毫秒 clientPort=2181 # 连接端口 dataDir=/home/Hadoop/zookeeper/data # 数据持久化路径 dataLogDir=/home/Hadoop/zookeeper/log # 日志保存路径 server.1=10.10.100.10:2888:3888
设置环境变量：
hongdada@ubuntu:/home/Hadoop/zookeeper/conf$ export ZOOKEEPER_HOME=/home/Hadoop/zookeeper
hongdada@ubuntu:/home/Hadoop/zookeeper/conf$ export PATH=$PATH:$ZOOKEEPER_HOME/bin
启动zookeeper:
hongdada@ubuntu:/home/Hadoop/zookeeper/conf$ cd . hongdada@ubuntu:/home/Hadoop/zookeeper/conf$ cd ../ hongdada@ubuntu:/home/Hadoop/zookeeper$ cd bin hongdada@ubuntu:/home/Hadoop/zookeeper/bin$ zkServer.sh start ZooKeeper JMX enabled by default Using config: /home/Hadoop/zookeeper/bin/../conf/zoo.cfg mkdir: 无法创建目录"/home/Hadoop/zookeeper/data # 数据持久化路径": 权限不够 Starting zookeeper ... /home/Hadoop/zookeeper/bin/zkServer.sh: 行 140: ./zookeeper.out: 权限不够 /home/Hadoop/zookeeper/bin/zkServer.sh: 行 149: /home/Hadoop/zookeeper/data # 数据持久化路径/zookeeper_server.pid: 没有那个文件或目录 FAILED TO WRITE PID hongdada@ubuntu:/home/Hadoop/zookeeper/bin$ sudo zkServer.sh start [sudo] hongdada 的密码： sudo: zkServer.sh：找不到命令 hongdada@ubuntu:/home/Hadoop/zookeeper/bin$ sudo ./zkServer.sh start ZooKeeper JMX enabled by default Using config: /home/Hadoop/zookeeper/bin/../conf/zoo.cfg Starting zookeeper ...

启动是./zkServer.sh start
