阿新 • • 發佈：2019-02-02
1、建立 /usr/local/services/zookeeper 資料夾：
mkdir -p /usr/local/services/zookeeper
2、進入到 /usr/local/services/zookeeper 目錄中：
cd /usr/local/services/zookeeper
3、下載 zookeeper-3.4.12.tar.gz：
wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.12/zookeeper-3.4.12.tar.gz
4、解壓縮 zookeeper-3.4.12.tar.gz：
tar -zxvf zookeeper-3.4.12.tar.gz
5、進入到 /usr/local/services/zookeeper/zookeeper-3.4.12/conf 目錄中：
cd zookeeper-3.4.12/conf/
6、複製 zoo_sample.cfg 檔案的並命名為為 zoo.cfg：
cp zoo_sample.cfg zoo.cfg
7、用 vim 開啟 zoo.cfg 檔案並修改其內容為如下：
# The number of milliseconds of each tick
# zookeeper 定義的基準時間間隔，單位：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
# 資料資料夾
dataDir=/usr/local/services/zookeeper/zookeeper-3.4.12/data
# 日誌資料夾
dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.12/logs
# the port at which the clients will connect
# 客戶端訪問 zookeeper 的埠號
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、儲存並關閉 zoo.cfg 檔案:
9、進入到 /usr/local/services/zookeeper/zookeeper-3.4.12/bin 目錄中：
cd ../bin/
10、用 vim 開啟 /etc/ 目錄下的配置檔案 profile：
vim /etc/profile
並在其尾部追加如下內容：
# idea - zookeeper-3.4.12 config start - 2018-04-26
export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.12/
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH
# idea - zookeeper-3.4.23 config start - 2018-04-26
11、使 /etc/ 目錄下的 profile 檔案即可生效：
source /etc/profile
12、啟動 zookeeper 服務：
zkServer.sh start
如列印如下資訊則表明啟動成功：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.12/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
13、查詢 zookeeper 狀態：
zkServer.sh status
14、關閉 zookeeper 服務：
zkServer.sh stop
如列印如下資訊則表明成功關閉：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.12/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
15、重啟 zookeeper 服務：
zkServer.sh restart
如列印如下資訊則表明重啟成功：
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.12/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/services/zookeeper/zookeeper-3.4.12/bin/../conf/zoo.cfg

cd /usr/local/services/zookeeper
3、下載 zookeeper-3.4.12.tar.gz：
