zookeeper以及集群的搭建

今天我来写一写zookeeper集群的搭建流程

1.zookeeper的搭建不难,难的是对他的理解以及良好的使用.单机版的zookeeper只需要解压后直接命令 启动即可 解压zookeeper，tar -zxvf zookeeper-3.4.6.tar.g

2.集群的话,需要复制文件 把单机版的zookeeper-3.4.6拷贝到/usr/local/solrcloud下，复制三份分别并将目录名改为zookeeper1、zookeeper2、zookeeper3

3.进入zookeeper1文件夹，创建data目录。并在data目录中创建一个myid文件内容为“1”（echo 1 >> data/myid）。

4.进入conf文件夹，把zoo_sample.cfg改名为zoo.cfg

5.修改zoo.cfg。 修改： dataDir=/usr/local/solrcloud/zookeeper1/data clientPort=2181（zookeeper2中为2182、zookeeper3中为2183） 添加： server.1=192.168.25.150:2881:3881 server.2=192.168.25.150:2882:3882 server.3=192.168.25.150:2883:3883

6.接下来把剩下的两个全部按照这个方式来修改 注意:第二个的端口号和路径要改,而添加的server不变 后面端口依次改为2182和2183

# 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=/usr/local/solrcloud/zookeeper1/data

# 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.htm

l#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=192.168.25.150:2881:3881

server.2=192.168.25.150:2882:3882

server.3=192.168.25.150:2883:3883

7.修改完成后分别启动三个zookeeper /usr/local/solrcloud/zookeeper1/bin/zkServer.sh start /usr/local/solrcloud/zookeeper2/bin/zkServer.sh start

/usr/local/solrcloud/zookeeper3/bin/zkServer.sh start

8.查看zookeeper的状态 /usr/local/solrcloud/zookeeper1/bin/zkServer.sh status /usr/local/solrcloud/zookeeper2/bin/zkServer.sh status /usr/local/solrcloud/zookeeper3/bin/zkServer.sh status

9.最后记得添加端口号,或者关闭防火墙
