centos7 单台zookeeper安装

1、创建 /usr/local/services/zookeeper 文件夹：

 mkdir -p /usr/local/services/zookeeper

2、进入到 /usr/local/services/zookeeper 目录中：

cd /usr/local/services/zookeeper

3、下载 zookeeper-3.4.10.tar.gz：

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz

4、解压缩 zookeeper-3.4.10.tar.gz：

tar -zxvf zookeeper-3.4.10.tar.gz

5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.10/conf 目录中：

cd zookeeper-3.4.10/conf/

6、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：

cp zoo_sample.cfg zoo.cfg

7、用 vim 打开 zoo.cfg 文件并修改其内容为如下：

# The number of milliseconds of each tick

# zookeeper 定义的基准时间间隔，单位：毫秒 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

 

# 数据文件夹 dataDir=/usr/local/services/zookeeper/zookeeper-3.4.10/data

# 日志文件夹 dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.10/logs

# the port at which the clients will connect

# 客户端访问 zookeeper 的端口号 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

 

8、保存并关闭 zoo.cfg 文件:

9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.10/bin 目录中：

cd ../bin/

10、用 vim 打开 /etc/ 目录下的配置文件 profile：

vim /etc/profile

并在其尾部追加如下内容：

# idea - zookeeper-3.4.10 config start - 2016-09-08

export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.10/

export PATH=$ZOOKEEPER_HOME/bin:$PATH

export PATH # idea - zookeeper-3.4.10 config start - 2016-09-08

11、使 /etc/ 目录下的 profile 文件即可生效：

source /etc/profile

12、启动 zookeeper 服务：

zkServer.sh start

如打印如下信息则表明启动成功：

ZooKeeper JMX enabled by default

Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

13、查询 zookeeper 状态：

zkServer.sh status

14、关闭 zookeeper 服务：

zkServer.sh stop

如打印如下信息则表明成功关闭：

ZooKeeper JMX enabled by default

Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg

Stopping zookeeper ... STOPPED

15、重启 zookeeper 服务：

zkServer.sh restart

如打印如下信息则表明重启成功：

ZooKeeper JMX enabled by default

Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg

ZooKeeper JMX enabled by default

Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg

Stopping zookeeper ... STOPPED

ZooKeeper JMX enabled by default

Using config: /usr/local/services/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED
