linux（centos）下zookeeper安装和配置

zookeeper安装

cd /tmp
wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz
sudo su
mkdir  /opt/yourpath/
tar xvf zookeeper-3.4.11.tar.gz -C /opt/yourpath/
cd  /opt/yourpath/
mv zookeeper-3.4.11/ zookeeper
cd zookeeper
mkdir data
mkdir log

myid文件

data目录下新建myid文件，写入一个id（在ip上取一个不同的值，区分开，这个值会和下面的zoo.cfg的一个值有关）

[[email protected] data]# pwd
/opt/interlive/yourpath/data
[[email protected] data]# cat myid
179

zoo.cfg文件

conf目录下，新建zoo.cfg文件，写入配置，参考之前的配置。
zoo.cfg的内容如下

# 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=/opt/interlive/zookeeper/data
dataLogDir=/opt/interlive/zookeeper/log
# the port at which the clients will connect
clientPort=2181
server.179=10.0.100.179:2888:3888
server.180=10.0.100.180:2888:3888
server.181=10.0.100.181:2888:3888
# the maximum number of client connections.
# increase this if you need to handle more clients
maxClientCnxns=0
#
# 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=10
# Purge task interval in hours
# Set to "0" to disable auto purge feature
autopurge.purgeInterval=4

启动

/bin/yum install java
cd /opt/interlive/zookeeper/bin
 ./zkServer.sh start

建立节点

cd /opt/yourpath/zookeeper/bin
./zkCli.sh -server 10.0.100.179:2181;10.0.100.180:2181;10.0.100.181:2181
create /online "online"
create /online/yournode "yournode"
create /online/yournode/yournodesub "yournodesub"

查看节点

ls /
ls /online
