Centos 7 安装部署 zookeeper

客户端连接 ： zkCli.cmd(sh) -server ip:2181

下载 zookeeper-3.4.9.tar.gz：wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz解压缩 zookeeper-3.4.9.tar.gz：tar -zxvf zookeeper-3.4.9.tar.gz -C /agui/zookeeper/进入到 /agui/zookeeper/zookeeper-3.4.9/conf 目录中：cd /agui/zookeeper/zookeeper-3.4.9/conf/复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：cp zoo_sample.cfg  zoo.cfgrm -f zoo_sample.cfg用 vim 打开 zoo.cfg 文件并修改其内容为如下：    # The number of milliseconds of each tick    # zookeeper 定义的基准时间间隔，单位：毫秒    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=/tmp/zookeeper    # 数据文件夹    dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data    # 日志文件夹    dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/logs    # the port at which the clients will connect    # 客户端访问 zookeeper 的端口号    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保存并关闭 zoo.cfg 文件:

配置环境变量(此配置可有可无)

进入到 /agui/zookeeper/zookeeper-3.4.9/bin 目录中：cd ../bin/用 vim 打开 /etc/ 目录下的配置文件 profile：vim /etc/profile并在其尾部追加如下内容：# idea - zookeeper-3.4.9 config start - 2016-09-08export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/export PATH=$ZOOKEEPER_HOME/bin:$PATHexport PATH使 /etc/ 目录下的 profile 文件即可生效：source /etc/profile
