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、修改防火墙：开启端口 2181
vi /etc/sysconfig/iptables
13、 重启防火墙
service iptables restart
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 安装 dubbo-admin
