zookeeper伪分布式安装

1.前提条件

需要安装jdk,尽量关闭防火墙

2.开始安装

• wget https://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
• tar -zxvf zookeeper-3.4.9.tar.gz
• ln -s zookeeper-3.4.9.tar.gz zk
• cd zk/conf
• cp zoo_sample.cfg zoo1.cfg、cp zoo_sample.cfg zoo2.cfg、cp zoo_sample.cfg zoo3.cfg
• 分别编辑zoo1.cfg、zoo2.cfg、zoo3.cfg

# The number of milliseconds of each tick
#zk时间单元(毫秒)
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
# floower启动过程中从leader同部数据的时间限制
#如果集群规模大，数据量多的话，适当调大此参数
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# 快照文件snapshot的存储目录
dataDir=/usr/local/src/zookeeper/data/zk1
# 事务日志目录
dataLogDir=/usr/local/src/zookeeper/log/zk1
# 客户端与服务端通信口号
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
#第一个是服务端通信的端口号，第二个是zk选举端口号
server.1=localhost:2187:2887
server.2=localhost:2188:2888
server.3=localhost:2189:2189

-创建相应的dataDir dataLogDir目录(在相应的dataDir目录下创建myid)

• echo "1" > /usr/local/src/zookeeper/data/zk1/myid
• echo "2" > /usr/local/src/zookeeper/data/zk2/myid
• echo "3" > /usr/local/src/zookeeper/data/zk3/myid

3.启动zookeeper

• 分别启动zookeeper 在bin目录中执行 ./zkServer.sh start ../conf/zoo1.cfg ./zkServer.sh start ../conf/zoo2.cfg ./zkServer.sh start ../conf/zoo3.cfg

4.检查是否启动成功

• ./zkServer.sh status ../conf/zoo1.cfg

• zkCli.sh -server localhost:2181, localhost:2182, localhost:2183
