1.下载安装zookeeper
|
#下载地址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/ |
2.配置zookeeper,以下操作在三台server上执行
|
#创建配置文件 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.2=cc-staging-front2:2888:3888 server.3=cc-staging-session:2888:3888 #创建数据目录 #配置myid文件 在dataDir目录下新建myid文件并设置id号 id号即为zoo.cfg文件中server.后的数字，如server.1=cc-monitor:2888:3888即表示cc-monitor机器中的myid号为1 #分别在三台server设置对应的id echo 1 > /tmp/zookeeper/myid echo 2 > /tmp/zookeeper/myid echo 3 > /tmp/zookeeper/myid #添加环境变量 vi /etc/profile export ZOOKEEPER_HOME=/usr/local/zookeeper export PATH=$PATH:$ZOOKEEPER_HOME/bin source /etc/profile |
3.启动服务
|
# 启动zkserver,不报错就行 #$ZOOKEEPER_HOME/bin/zkServer.sh start JMX enabled by default Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg Starting zookeeper ... STARTED #查看三台zkserver的状态,1台leader2台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.进行同步测试
|
#在其中1台上创建文件 zkCli.sh -server 127.0.0.1:2181 create /mytest test #在另外2台上进行查询，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 # |
