zookeeper集羣安裝部署

1.下載安裝zookeeper

#下載地址http://www.apache.org/dyn/closer.cgi/zookeeper wget http://labs.mop.com/apache-mirror/zookeeper/zookeeper-3.4.5/zookeeper-3.4.5.tar.gz tar zxvf zookeeper-3.4.5.tar.gz -C  /usr/local/ mv zookeeper-3.4.5 zookeeper

2.配置zookeeper,如下操做在三臺server上執行

#建立配置文件 cd /usr/local/zookeeper cp zoo_sample.cfg zoo.cfg vi zoo.cfg tickTime=2000 initLimit=10 syncLimit=5 dataDir=/tmp/zookeeper clientPort=2181 server.1=cc-monitor:2888:3888 server.2=cc-staging-front2:2888:3888 server.3=cc-staging-session:2888:3888 #建立數據目錄 mkdir -p /tmp/zookeeper #配置myid文件 在dataDir目錄下新建myid文件並設置id號 id號即爲zoo.cfg文件中server.後的數字，如server.1=cc-monitor:2888:3888即表示cc-monitor機器中的myid號爲1 #分別在三臺server設置對應的id echo 1 > /tmp/zookeeper/myid echo 2 > /tmp/zookeeper/myid echo 3 > /tmp/zookeeper/myid #添加環境變量 vi /etc/profile export   ZOOKEEPER_HOME=/usr/local/zookeeper export   PATH=$PATH:$ZOOKEEPER_HOME/bin source /etc/profile

3.啓動服務

# 啓動zkserver,不報錯就行 #$ZOOKEEPER_HOME/bin/zkServer.sh  start JMX enabled by default Using config:  /usr/local/zookeeper/bin/../conf/zoo.cfg Starting zookeeper ... STARTED #查看三臺zkserver的狀態,1臺leader2臺follower [root@cc-monitor conf]#  $ZOOKEEPER_HOME/bin/zkServer.sh status JMX enabled by default Using config:  /usr/local/zookeeper/bin/../conf/zoo.cfg Mode: follower [root@cc-staging-front2 conf]# $ZOOKEEPER_HOME/bin/zkServer.sh  status JMX enabled by default Using config:  /usr/local/zookeeper/bin/../conf/zoo.cfg Mode: leader [root@cc-staging-session conf]#  $ZOOKEEPER_HOME/bin/zkServer.sh status JMX enabled by default Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg Mode: follower

4.進行同步測試

#在其中1臺上建立文件 zkCli.sh -server  127.0.0.1:2181 create /mytest test #在另外2臺上進行查詢，是否同步 [zk: 127.0.0.1:2181(CONNECTED) 0] ls / [mytest, zookeeper] [zk: 127.0.0.1:2181(CONNECTED) 2] get  /mytest test cZxid = 0x100000002 ctime = Wed Apr 24 22:45:04 PDT 2013 mZxid = 0x100000002 mtime = Wed Apr 24 22:45:04 PDT 2013 pZxid = 0x100000002 cversion = 0 dataVersion = 0 aclVersion = 0 ephemeralOwner = 0x0 dataLength = 4 numChildren = 0 #
