安装及部署

一. 单机安装、配置

1、下载zookeeper二进制安装包

• 下载

curl -L -O http://apache.fayea.com/zookeeper/stable/zookeeper-3.4.6.tar.gz

• 解压

tar zxvf zookeeper-3.4.6.tar.gz

2、设置环境变量

ZOOKEEPER_HOME关键字为添加的配置项

# /etc/profile# System wide environment and startup programs, for login setup# Functions and aliases go in /etc/bashrc# It's NOT a good idea to change this file unless you know what you# are doing. It's much better to create a custom.sh shell script in# /etc/profile.d/ to make custom changes to your environment, as this# will prevent the need for merging in future updates.pathmunge () {    case ":${PATH}:" in        *:"$1":*)            ;;        *)            if [ "$2" = "after" ] ; then                PATH=$PATH:$1            else                PATH=$1:$PATH            fi    esac}if [ -x /usr/bin/id ]; then    if [ -z "$EUID" ]; then        # ksh workaround        EUID=`id -u`        UID=`id -ru`    fi    USER="`id -un`"    LOGNAME=$USER    MAIL="/var/spool/mail/$USER"fi# Path manipulationif [ "$EUID" = "0" ]; then    pathmunge /sbin    pathmunge /usr/sbin    pathmunge /usr/local/sbinelse    pathmunge /usr/local/sbin after    pathmunge /usr/sbin after    pathmunge /sbin afterfiHOSTNAME=`/bin/hostname 2>/dev/null`HISTSIZE=1000if [ "$HISTCONTROL" = "ignorespace" ] ; then    export HISTCONTROL=ignorebothelse    export HISTCONTROL=ignoredupsfiexport PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL# By default, we want umask to get set.

3、配置

配置文件存放在$ZOOKEEPER_HOME/conf/目录下，将zoo_sample.cfd文件名称改为zoo.cfg, 缺省的配置内容如下：

# The number of milliseconds of each ticktickTime=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# the port at which the clients will connectclientPort=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

• 配置说明：

tickTime：这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个 tickTime 时间就会发送一个心跳。

dataDir：顾名思义就是 Zookeeper 保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。

dataLogDir: log目录, 同样可以是任意目录. 如果没有设置该参数, 将使用和dataDir相同的设置。

clientPort：这个端口就是客户端连接 Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求。

4、启动Zookeeper

当这些配置项配置好后，你现在就可以启动zookeeper了：

./zkServer.sh start #启动netstat -tunlp|grep 2181 #查看zookeeper端口./zkServer.sh stop #停止

二. 集群安装、配置

集群安装与配置暂时省略，下次在作补充。
