安装ZooKeeper

1.3 安装ZooKeeper

1.3.1 下载ZooKeeper压缩包

wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz

1.3.2 解压ZooKeeper压缩包

tar -zxvf zookeeper-3.4.13.tar.gz

1.3.3 删除ZooKeeper压缩包

rm -f zookeeper-3.4.13.tar.gz

1.3.4 拷贝配置文件

cd /usr/local/zookeeper-3.4.13/conf

cp zoo_sample.cfg zoo.cfg

vim zoo.cfg

这个zoo.cfg是zookeeper的配置文件，这里我搭的是单机版，如果想搭集群版也是通过修改配置文件即可。

# 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/zookeeper-3.4.13/data    #这里最好自己设置
# 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=cnblogs01:8888:9888         #这里修改为自己的主机名或者IP
server.2=cnblogs02:8888:9888
server.3=cnblogs03:8888:9888

创建/usr/local/zookeeper-3.4.13/data文件夹，新建一个myid,写入1

mkdir data

vim myid

1.3.5 启动ZooKeeper

/usr/local/zookeeper-3.4.13/bin/zkServer.sh start
