配置/运行

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:
export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.14/
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH
使 /etc/ 目录下的 profile 文件即可生效:

source /etc/profile

启动 zookeeper 服务:

[root@localhost bin]# zkServer.sh start
如打印如下信息则表明启动成功:

Using config: /usr/local/services/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

查询 zookeeper 状态:

[root@localhost bin]# zkServer.sh status
打印信息
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.14/bin/../conf/zoo.cfg
Mode: standalone

关闭 zookeeper 服务:

zkServer.sh stop
