安裝及部署
回到頂部一. 單機安裝、配置
1、下載zookeeper二進制安裝包
-
下載
curl -L -O http://apache.fayea.com/zookeeper/stable/zookeeper-3.4.6.tar.gz
-
解壓
tar zxvf zookeeper-3.4.6.tar.gz
2、設置環境變量
ZOOKEEPER_HOME關鍵字為添加的配置項
# /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/$USER"
fi
# Path manipulation
if [ "$EUID" = "0" ]; then
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
else
pathmunge /usr/local/sbin after
pathmunge /usr/sbin after
pathmunge /sbin after
fi
HOSTNAME=`/bin/hostname 2>/dev/null`
HISTSIZE=1000
if [ "$HISTCONTROL" = "ignorespace" ] ; then
export HISTCONTROL=ignoreboth
else
export HISTCONTROL=ignoredups
fi
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL
# By default, we want umask to get set. This sets it for login shell
# Current threshold for system reserved uid/gids is 200
# You could check uidgid reservation validity in
# /usr/share/doc/setup-*/uidgid file
if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then
umask 002
else
umask 022
fi
for i in /etc/profile.d/*.sh ; do
if [ -r "$i" ]; then
if [ "${-#*i}" != "$-" ]; then
. "$i"
else
. "$i" >/dev/null 2>&1
fi
fi
done
unset i
unset pathmunge
JAVA_HOME=/usr/java/jdk1.7.0_51
#zookeeper環境變量設置
ZOOKEEPER_HOME=/usr/local/logdeal/zookeeper-3.4.6
PATH=$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$ZOOKEEPER_HOME/lib:
TOMCAT_HOME=/usr/local/tomcat7
CATALINA_HOME=/usr/local/tomcat7
export ZOOKEEPER_HOME
export JAVA_HOME
export PATH
export CLASSPATH
export TOMCAT_HOME
export CATALINA_HOME
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH
3、配置
配置文件存放在$ZOOKEEPER_HOME/conf/目錄下，將zoo_sample.cfd文件名稱改為zoo.cfg, 缺省的配置內容如下：
# The number of milliseconds of each tick 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 # the port at which the clients will connect 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
-
配置說明：
tickTime：這個時間是作為 Zookeeper 服務器之間或客戶端與服務器之間維持心跳的時間間隔，也就是每個 tickTime 時間就會發送一個心跳。
dataDir：顧名思義就是 Zookeeper 保存數據的目錄，默認情況下，Zookeeper 將寫數據的日誌文件也保存在這個目錄裏。
dataLogDir: log目錄, 同樣可以是任意目錄. 如果沒有設置該參數, 將使用和dataDir相同的設置。
clientPort：這個端口就是客戶端連接 Zookeeper 服務器的端口，Zookeeper 會監聽這個端口，接受客戶端的訪問請求。
4、啟動Zookeeper
當這些配置項配置好後，你現在就可以啟動zookeeper了：
./zkServer.sh start #啟動 netstat -tunlp|grep 2181 #查看zookeeper端口 ./zkServer.sh stop #停止回到頂部
二. 集群安裝、配置
集群安裝與配置暫時省略，下次在作補充。
