zookeeper集群安装

(集群安装测试时以ip为例说明，正式上线后可以配主机名称)

1)解压zookeeper安装包

tar -zxvfzookeeper-3.4.5.tar.gz

2)进入zookeeper-3.4.5文件夹,创建data和log

创建目录并赋于写权限

指定zookeeper的数据存放目录和日志目录

3)拷贝zookeeper配制文件zoo_sample.cfg

拷贝zookeeper配制文件zoo_sample.cfg并重命名zoo.cfg

cp /solrcloud/zookeeper-3.4.5/conf/zoo_sample.cfg/solrcloud/zookerper-3.4.5/conf/zoo.cfg

4)修改zoo.cfg

加入dataDir=/solrcloud/zookeeper-3.4.5/data

dataLogDir=/solrcloud/zookeeper-3.4.5/log

server.1=192.168.56.11:2888:3888

server.2=192.168.56.12:2888:3888

server.3=192.168.56.13:2888:3888

zoo.cfg配制完后如下:

# 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=/solrcloud/zookeeper-3.4.5/data

dataLogDir=/solrcloud/zookeeper-3.4.5/log

# the port at which the clients will connect

clientPort=2181

#

# 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=192.168.56.11:2888:3888

server.2=192.168.56.12:2888:3888

server.3=192.168.56.13:2888:3888

5)进入data文件夹建立对应的myid文件

例如server.1=192.168.56.11 data文件夹下的myid文件内容为1

6)制zookeeper-3.4.5文件夹到其他机器

将data文件夹下的myid修改为对应的server.【序号】

7)开启zookeeper的端口

/sbin/iptables -I INPUT -p tcp --dport 2181-j ACCEPT

/sbin/iptables -I INPUT -p tcp --dport 2888-j ACCEPT

/sbin/iptables -I INPUT -p tcp --dport 3888-j ACCEPT

/sbin/iptables -I INPUT -p tcp --dport 8080

-j ACCEPT--顺便启用tomcat 8080端口

/etc/rc.d/init.d/iptables save#将更改进行保存

/etc/init.d/iptables restart#重启防火墙以便改动生效

8)启动zookeeper

进入bin

./zkServer.sh start

查看集群状态

./zkServer.sh status刚启动可能会有错误，集群中其他节点一并起来后就正常了

./zkCli.sh 

ls /等命令可以查看zookeeper上面的文件。

例如： ls /live_nodes 查看各节点存活情况

rmr 可以删除文件
