linux安装zookeeper

小明的个人博客

1：下载zookeeper源码包

• 点我进入下载页面

• 如下图所示,这里以zookeeper-3.4.10为例

2：解压源码包,更换名称为zookeeper(这里名称随意),大致内容如下

[root@10-10-127-163 tar]# tar -zxvf zookeeper-3.4.10.tar.gz  解压文件
[root@10-10-127-163 tar]# mv zookeeper-3.4.10 /usr/local/bin/app/  移动文件到app目录
[root@10-10-127-163 app]# mv zookeeper-3.4.10/ zookeeper 更换文件夹名称
[root@10-10-127-163 zookeeper]# ll  文件夹内容

3：编辑配置文件

切换到zookeeper目录下的conf目录下，重新复制一份zoo_sample.cfg文件并命名为zoo.cfg
1 ：配置dataDir ZK启动目录
2： 配置dataLogDir 日志目录

[root@10-10-127-163 zookeeper]# cd conf/
[root@10-10-127-163 conf]# cp zoo_sample.cfg zoo.cfg  重新命名为zoo.cfg
[root@10-10-127-163 conf]# vim zoo.cfg  编辑配置文件

# 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=/tmp/zookeeper # 这里自定义配置
dataLogDir=/tmp/zookeeper/log #自定义配置 存放日志文件
# 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

4：配置环境变量

[root@10-10-127-163 conf]# vim /etc/profile  添加下面2句
export ZOOKEEPER=/usr/local/bin/app/zookeeper
export PATH=$ZOOKEEPER/bin:$PATH
[root@10-10-127-163 conf]# source /etc/profile  刷新配置文件

5：启动zookeeper 任务目录下执行以下命令

[root@10-10-127-163 zookeeper]# zkServer.sh start  启动zookeeper
ZooKeeper JMX enabled by default
Using config: /usr/local/bin/app/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@10-10-127-163 zookeeper]#  zkServer.sh status  查看运行状态
ZooKeeper JMX enabled by default
Using config: /usr/local/bin/app/zookeeper/bin/../conf/zoo.cfg
Mode: standalone  #显示standalone则说明启动成功
[root@10-10-127-163 zookeeper]# 

5：连接zookeeper

[root@10-10-127-163 zookeeper]# zkCli.sh
