一、安装好java

二、配置 zookeeper：

1、创建 /usr/local/services/zookeeper 文件夹：mkdir -p /usr/local/services/zookeeper2、进入到 /usr/local/services/zookeeper 目录中：cd /usr/local/services/zookeeper3、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.gz4、解压缩 zookeeper-3.4.9.tar.gz：tar -zxvf zookeeper-3.4.9.tar.gz5、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.cfg7、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 takeinitLimit=10# The number of ticks that can pass between # sending a request and getting an acknowledgementsyncLimit=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=18、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 - 2016-09-08export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/export PATH=$ZOOKEEPER_HOME/bin:$PATHexport PATH# idea - zookeeper-3.4.9 config start - 2016-09-0811、使 /etc/ 目录下的 profile 文件即可生效：source /etc/profile12、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 defaultUsing config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfgStarting zookeeper ... STARTED13、查询 zookeeper 状态：zkServer.sh status14、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 defaultUsing config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfgStopping zookeeper ... STOPPED15、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 defaultUsing config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfgZooKeeper JMX enabled by defaultUsing config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfgStopping zookeeper ... STOPPEDZooKeeper JMX enabled by defaultUsing config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED



如果出现 这类错误：

[root@localhost ~]# /usr/zookeeper/bin/zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /usr/zookeeper/bin/../conf/zoo.cfg
Stopping zookeeper ... /usr/zookeeper/bin/zkServer.sh: 第 182 行:kill: (2453) - 没有那个进程

解决：安装配置好java之后，需要赋予权限：

chmod +x /usr/java/jdk1.8/bin/java
