1、创建 /usr/local/zookeeper 文件夹
<span style="float:none;background-color:transparent;color:rgb(61,70,77);font-family:'Pingfang SC', STHeiti, 'Lantinghei SC', 'Open Sans', Arial, 'Hiragino Sans GB', 'Microsoft YaHei', 'WenQuanYi Micro Hei', SimSun, sans-serif;font-size:16px;font-style:normal;font-variant:normal;font-weight:400;letter-spacing:normal;line-height:28px;text-align:left;text-decoration:none;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;">shell>mkdir -p /usr/local/zookeeper</span>2、进入到 /usr/local/zookeeper 目录中
shell>cd /usr/local/zookeeper
代码解释3、.进入zookeeper官网找到下载镜像连接
https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/
下载zookeeper-3.5.4-beta.tar.gz
shell> wget htps://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.5.4-beta/zookeeper-3.5.4-beta.tar.gz
代码解释4、 解压缩 zookeeper-3.5.4-beta.tar.gz
shell>tar -zxvf zookeeper-3.5.3-beta.tar.gz
代码解释
5、配置文件夹
文件移至/usr/local/zookeeper/下
shell>mv /usr/local/webtools/zookeeper-3.5.4-beta /usr/local/zookeeper/
代码解释进入到 /usr/local/zookeeper/zookeeper-3.5.4-beta/conf 目录中
shell>cd zookeeper-3.5.4-beta/conf/
代码解释复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg
shell>cp zoo_sample.cfg zoo.cfg
代码解释用 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/zookeeper/zookeeper-3.5.3-beta/data
# 日志文件夹
dataLogDir=/usr/local/zookeeper/zookeeper-3.5.3-beta/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
代码解释保存并关闭 zoo.cfg 文件
用 vim 打开 /etc/ 目录下的配置文件 profile并在其尾部追加如下内容
shell>vim /etc/profile
代码解释 export ZOOKEEPER_HOME=/usr/local/zookeeper/zookeeper-3.5.4-beta
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH
代码解释使 /etc/ 目录下的 profile 文件即可生效：source /etc/profile
6、操作命令
shell>zkServer.sh start
代码解释启动 zookeeper 服务如打印如下信息则表明启动成功:
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
代码解释shell>zkServer.sh status
查询 zookeeper 状态
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: standalone
代码解释shell>zkServer.sh stop
关闭 zookeeper 服务如打印如下信息则表明成功关闭：
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
代码解释shell>zkServer.sh restart
重启 zookeeper 服务如打印如下信息则表明重启成功：
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Stopping zookeeper ... no zookeeper to stop (could not find file /usr/local/zookeeper/zookeeper-3.5.4-beta/data/zookeeper_server.pid)
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
