  7 # 2、进入到 /usr/local/src/zookeeper 目录中
  8 [root@centos-linux src]# cd /usr/local/src/zookeeper

 10 # 3、下载 zookeeper-3.5.2-alpha.tar.gz
 11 [root@centos-linux zookeeper]# wget http://mirrors.shu.edu.cn/apache/zookeeper/zookeeper-3.5.2-alpha/zookeeper-3.5.2-alpha.tar.gz

 22 
 23 #4、解压缩 zookeeper-3.5.2-alpha.tar.gz
 24 [root@centos-linux zookeeper]# tar -zxvf zookeeper-3.5.2-alpha.tar.gz
 25 
 26 #5、进入到 /usr/local/src/zookeeper/zookeeper-3.5.2-alpha/conf 目录中
 27 
 28 [root@centos-linux zookeeper]# cd zookeeper-3.5.2-alpha/conf
 29 [root@centos-linux conf]# ls
 30 configuration.xsl log4j.properties zoo_sample.cfg
 31 
 32 # 6、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg
 33 [root@centos-linux conf]# cp zoo_sample.cfg zoo.cfg
 34 [root@centos-linux conf]# ls
 35 configuration.xsl log4j.properties zoo.cfg zoo_sample.cfg
 36 
 37 # 7、用 vim 打开 zoo.cfg 文件并修改其内容为如下
 38 [root@centos-linux conf]# vim zoo.cfg
 39 
 40 # dataDir=/tmp/zookeeper
 41 # The number of milliseconds of each tick
 42 tickTime=2000
 43 # The number of ticks that the initial 
 44 # synchronization phase can take
 45 initLimit=10
 46 # The number of ticks that can pass between 
 47 # sending a request and getting an acknowledgement
 48 syncLimit=5
 49 # the directory where the snapshot is stored.
 50 # do not use /tmp for storage, /tmp here is just 
 51 # example sakes.
 52 # dataDir=/tmp/zookeeper
 53 #数据文件夹
 54 dataDir=/urs/local/src/zookeeper/zookeeper-3.5.2-alpha/data
 55 #日志文件夹
 56 dataLogDir=/urs/local/src/zookeeper/zookeeper-3.5.2-alpha/logs
 57 # the port at which the clients will connect
 58 clientPort=2181
 59 # the maximum number of client connections.
 60 # increase this if you need to handle more clients
 61 #maxClientCnxns=60
 62 #
 63 # Be sure to read the maintenance section of the 
 64 # administrator guide before turning on autopurge.
 65 #
 66 
 67 # 8、保存并关闭 zoo.cfg 文件
 68 [root@centos-linux conf]# cd ..
 69 [root@centos-linux zookeeper-3.5.2-alpha]# cd bin
 70 [root@centos-linux bin]# ls
 71 README.txt zkCleanup.sh zkCli.cmd zkCli.sh zkEnv.cmd zkEnv.sh zkServer.cmd zkServer-initialize.sh zkServer.sh
 72 
 73 #9、用 vim 打开 /etc/ 目录下的配置文件 profile
 74 
 75 [root@centos-linux bin]# vim /etc/profile
 76 
 77 #10、并在其尾部追加如下内容
 78 
 79 # idea - zookeeper-3.5.2 config start - 2017-04-20
 80 
 81 export ZOOKEEPER_HOME=/usr/local/src/zookeeper/zookeeper-3.5.2-alpha/
 82 export PATH=$ZOOKEEPER_HOME/bin:$PATH
 83 export PATH
 84 
 85 # idea - zookeeper-3.5.2 config end - 2017-04-20
 86 
 87 # 11、使 /etc/ 目录下的 profile 文件即可生效
 88 [root@centos-linux bin]# source /etc/profile
