zookeeper部署安装

1、安装jdk环境

zookeeper官网

http://mirror.bit.edu.cn/apache/zookeeper/

主机：10.1.1.161

2、修改hosts

10.1.1.161 edu-provider-01

3、创建服务存放目录

mkdir /home/wusc && cd /home/wusc

4、下载解压zookeeper

使用 3.4.10版本

wgethttp://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz

tar xvfzookeeper-3.4.10.tar.gz

5、创建存放数据和日志的目录

cd zookeeper-3.4.10

mkdir data

mkdir logs

6、拷贝配置文件并修改

cd conf/

cp zoo_sample.cfg zoo.cfg

修改配置文件

vim 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=/home/wusc/zookeeper-3.4.10/data

dataLogDir=/home/wusc/zookeeper-3.4.10/logs

# 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

server.1=edu-provider-01:2888:3888

#2888端口是zookeeper服务之间通信的端口

#3888端口是zookeeper与其他应用程序通信的端口

7、创建myid文件

cd ../data/

vim myid

1

## "1"是在zoo.cfg中配置的server.1

8、添加zookeeper环境

vim /etc/profile

## zookooper

export ZOOKEEPER_HOME=/home/wusc/zookeeper-3.4.10

export PATH=$ZOOKEEPER_HOME/bin:$PATH

使配置文件生效

source /etc/profile

9、修改防火墙或关闭防火墙

vim /etc/sysconfig/iptables

# zookeeper

-A INPUT -m state --state NEW -m tcp -p tcp --dport 2181 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 2888 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3888 -j ACCEPT

重启iptables

service iptables restart

10、启动测试zookeeper

cd bin/

sh zkServer.sh start

Using config: /home/wusc/zookeeper-3.4.10/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

查看状态：

# sh zkServer.sh status

ZooKeeper JMX enabled by default

Using config: /home/wusc/zookeeper-3.4.10/bin/../conf/zoo.cfg

Mode:standalone

重启

# sh zkServer.sh restart
