在 CentOS7 上安装 zookeeper-3.4.9 服务

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
