初识metaq
zookeeper部署,这里单机zk为例。
wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.5/zookeeper-3.4.6.tar.gz
tar -zxvf zookeeper-3.4.6.tar.gz
cd zookeeper-3.4.6
mkdir data
cp conf/zoo_sample.cfg conf/zoo.cfg
改动zk的配置文件。将data路径dataDir的值设置为zookeeper-3.4.6下的data
hadoop@yard02:~/bigdata/zookeeper-3.4.6$ cat conf/zoo.cfg
# 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=/home/hadoop/bigdata/zookeeper-3.4.6/data
# 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
metaq部署
这里使用单机多实例測试
wget http://fnil.net/downloads/metaq-server-1.4.6.2.tar.gz
tar -zxvf metaq-server-1.4.6.2.tar.gz
cd taobao/
cp -rf metamorphosis-server-wrapper ../metaq9123
cp -rf metamorphosis-server-wrapper ../metaq9124
cp -rf metamorphosis-server-wrapper ../metaq9125
单机多实例须要解决port冲突的问题
1。改动JMXport,改动服务port,改动dashboardWebport,zk地址
我这里保持metaq9123默认,改动metaq9124。metaq9125
vim metaq9124/conf/server.ini
serverPort=8124
dashboardHttpPort=8121
zk.zkConnect=192.168.137.2:2181
vim metaq9124/bin/env.sh
export JMX_PORT=9124
metaq9125相同,改动成不被占用的接口即可了 启动:
bin/metaServer.sh start
停止
bin/metaServer.sh stop
状态
bin/metaServer.sh status
zk上节点

1) /consumers:存放消费者列表以及消费记录。消费者列表主要是以组的方式存在。结构主要例如以下:
/consumers/xxGroup/ids/xxConsumerId:DATA(“:”后的DATA表示节点xxConsumerId相应的数据) 组内消费者Id;DATA为订阅主题列表。以”,”分隔
/consumers/xxGroup/offsets/xxTopic/分区N:DATA 组内主题分区N的消费进度。DATA为topic下分区N详细进度值
/consumers/xxGroup/owners/xxTopic/分区N:DATA 组内主题分区N的的消费者。DATA为消费者ID,表示XXTopic下分区N的数据由指定的消费者进行消费
2) /brokers/ids:存放Broker列表,假设Broker与Zookeeper失去连接,则会自己主动注销在/brokers/ids下的broker记录。样例例如以下:
/brokers/ids/xxBroker
3) /brokers/topics-pub:存放公布的主题列表以及相应的可发送消息的Broker列表,样例例如以下:
/brokers/topics-pub/xxTopic/xxBroker
/brokers/topics-pub下记录的是可发送消息到xxTopic的Broker列表,意味着有多少个Broker同意存储Client发送到Topic数据
4) /brokers/topics-sub:存放订阅的主题列表以及相应可订阅的Broker列表。样例例如以下:
/brokers/topics-sub/xxTopic/xxBroker
/brokers/topics-sub下记录的可订阅xxTopic的Broker列表,意味着有多少个Broker同意被Client订阅topic的数据
这里使用sohu-zookeeper-view来看了下节点信息。当中meta-example是group
