一、安装好java
二、配置 zookeeper：
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
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 本文转自yunlielai51CTO博客，原文链接：http://blog.51cto.com/4925054/1920382，如需转载请自行联系原作者
