篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了zookeeper集群部署相关的知识,希望对你有一定的参考价值。
前提:关闭防火墙
1、解压
cd /opt/module/
tar -zxvf apache-zookeeper-3.5.5-bin.tar.gz
2、创建数据文件和目录文件
在zookeeper的跟目录下创建两个文件夹data和log
cd /opt/module/apache-zookeeper-3.5.5-bin/
mkdir data
mkdir log
3、拷贝配置文件
cd /opt/module/apache-zookeeper-3.5.5-bin/conf/
cp zoo_sample.cfg zoo.cfg
配置文件更改
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=/opt/module/apache-zookeeper-3.5.5-bin/data
dataLogDir=/opt/module/apache-zookeeper-3.5.5-bin/log
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.0=192.168.1.100:2888:3888
server.1=192.168.1.101:2888:3888
server.2=192.168.1.102:2888:3888
4、创建服务器myid
在data目录下创建一个myid的文件,里面的值可以给个任意的值,但要和上述服务起server.x对应
cd /opt/module/apache-zookeeper-3.5.5-bin/data/
touch myid
5、集群拷贝
scp -r /opt/module/apache-zookeeper-3.5.5-bin root@hadoop101:/opt/module/apache-zookeeper-3.5.5-bin
scp -r /opt/module/apache-zookeeper-3.5.5-bin root@hadoop102:/opt/module/apache-zookeeper-3.5.5-bin
6、集群myid更改
进入到每个节点,修改myid值
集群系统环境变量添加:vi /etc/profile
export ZOOKEEPER_HOME=/opt/module/apache-zookeeper-3.5.5-bin
export PATH=
P
A
T
H
:
PATH:
PATH:ZOOKEEPER_HOME/bin
保存系统环境变量:source /etc/profile
关闭集群防火墙
7、集群启动
进入到每个节点启动
cd /opt/module/apache-zookeeper-3.5.5-bin
zkServer.sh start
zkServer.sh status
zkCli连接验证
zkCli.sh -server hadoop100:2181
