在 CentOS上安装 zookeeper-3.4.9 服务
1、创建 /usr/local/services/zookeeper 文件夹： mkdir -p /usr/local/services/zookeeper 2、进入到 /usr/local/services/zookeeper 目录中： cd /usr/local/services/zookeeper 3、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 4、解压缩 zookeeper-3.4.9.tar.gz： tar -zxvf zookeeper-3.4.9.tar.gz 5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/conf 目录中： cd zookeeper-3.4.9/conf/ 6、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg： cp zoo_sample.cfg zoo.cfg 7、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 8、保存并关闭 zoo.cfg 文件: 9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/bin 目录中： cd ../bin/ 10、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 - 2016-09-08 export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/ export PATH=$ZOOKEEPER_HOME/bin:$PATH export PATH # idea - zookeeper-3.4.9 config start - 2016-09-08 11、使 /etc/ 目录下的 profile 文件即可生效： source /etc/profile 12、启动 zookeeper 服务： zkServer.sh start 如打印如下信息则表明启动成功： ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg Starting zookeeper ... STARTED 13、查询 zookeeper 状态： zkServer.sh status 14、关闭 zookeeper 服务： zkServer.sh stop 如打印如下信息则表明成功关闭： ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg Stopping zookeeper ... STOPPED 15、重启 zookeeper 服务： zkServer.sh restart 如打印如下信息则表明重启成功： ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg Stopping zookeeper ... STOPPED ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg Starting zookeeper ... STARTED
