zookeeper相关安装

记录下安装zookeeper集群的过程

zookeeper集群搭建

本次安装集群需要3个节点，下面是我的节点信息：

node1 192.168.75.200
node2 192.168.75.201
node3 193.168.75.202

信息配置

下载安装后，解压到某个目录下面，复制一个zoo_sample.cfg文件并改名为zoo.cfg
下面是我的配置信息
配置dataDir,dataLogDir的属性值；clientPort端口号；相关集群节点信息

# 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=/root/packages/zookeeper3.5.6/data
dataLogDir=/root/packages/zookeeper3.5.6/log
# 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
#此处是重点关注的地方，其中0，1，2是myid里面的编号
server.0=192.168.75.200:2888:3888
server.1=192.168.75.201:2888:3888
server.2=192.168.75.202:2888:3888

在dataDir配置的目录下创建myid文件，写入节点对应的编号
开放2181，2888，3888端口(重点)

监控工具ZK UI安装

zkui参考这条教程

Shell一键启动脚本编写

这个启动脚本仅供参考：
start-zookeeper.sh

#!/bin/bash
echo "启动zookeeper中........"
#节点列表
nodes=("node1" "node2" "node3")
for node in ${nodes[@]}
do
    echo "$node:启动开始"
    ssh root@$node  "zkServer.sh start"
    echo "$node:启动成功"
done
echo "启动zookeeper成功"
echo "开启zookeeper客户端监控....."
cd /root/packages/zookeeper3.5.6/zkui/target
nohup java -jar zkui-2.0-SNAPSHOT-jar-with-dependencies.jar &
echo $! > tpid
exit0

stop-zookeeper.sh

#!/bin/bash
echo "关闭zookeeper中........"
nodes=("node1" "node2" "node3")
for node in ${nodes[@]}
do
    echo "$node:关闭开始"
    ssh root@$node  "zkServer.sh stop"
    echo "$node:关闭成功"
done
echo "关闭zookeeper成功"
echo "关闭zookeeper监控平台....."
cd /root/packages/zookeeper3.5.6/zkui/target
PID=$(cat tpid)
kill -9 $PID  && echo "监控服务停止成功...."
name=$(lsof -i:9090|tail -1|awk '"$1"!=""{print $2}')
if [ -z $name ]
then
        echo "No process can be used to killed!"
else
        id=$(lsof -i:9090|tail -1|awk '"$1"!=""{print $2}')
        kill -9 $id
        echo "Process name=$name($id) kill!"
fi
