Ubuntu 安装zookeeper

时间：2023-03-08 16:13:28

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

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
