Linux下zookeeper安装

• 注：演示过程中使用的是 centOS 6.5

1.下载

cd /usr/software/zookeper wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz

2.解压

tar -zxvf zookeeper-3.3.6.tar.gz cd zookeeper/zookeeper-3.3.6

3.配置

复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg

cp zoo_sample.cfg zoo.cfg

编辑：

# 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.
# 数据文件夹
dataDir=/usr/software/zookeeper/zookeeper-3.3.6/data
# 日志文件夹
dataLogDir=/usr/software/zookeeper/zookeeper-3.3.6/logs
# the port at which the clients will connect
clientPort=2181
server.1=192.168.32.129:2888:3888

4.添加环境变量

vim /etc/profile

export ZOOKEEPER_HOME=/usr/software/zookeeper/zookeeper-3.3.6/
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH

立即生效
source /etc/profile

5.启动 zookeeper 服务：

  zkServer.sh start

如打印如下信息则表明启动成功：

   ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
   Starting zookeeper ... STARTED

6.查询 zookeeper 状态：

zkServer.sh status

7.关闭 zookeeper 服务：

zkServer.sh stop

如打印如下信息则表明成功关闭：

ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED

8.重启 zookeeper 服务：

zkServer.sh restart

如打印如下信息则表明重启成功：

ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

9.附防墙命令

关闭命令：service iptables stop 

永久关闭防火墙：chkconfig iptables off

查看防火墙关闭状态：service iptables status
