在 CentOS7 上安装 zookeeper-3.4.9 服务

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-3.4.9.tar.gz：

	wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz

4、解压缩 zookeeper-3.4.9.tar.gz：

	tar -zxvf zookeeper-3.4.9.tar.gz

5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/conf 目录中：

	cd zookeeper-3.4.9/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-3.4.9/data

	# 日志文件夹

	dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/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-3.4.9/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-3.4.9 config start - 2016-09-08

	export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/

	export PATH=$ZOOKEEPER_HOME/bin:$PATH

	export PATH

	# idea - zookeeper-3.4.9 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-3.4.9/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-3.4.9/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-3.4.9/bin/../conf/zoo.cfg

	ZooKeeper JMX enabled by default

	Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg

	Stopping zookeeper ... STOPPED

	ZooKeeper JMX enabled by default

	Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg

	Starting zookeeper ... STARTED
