3.4 linux 安裝zookeeper
下載zookeeper安裝包
https://downloads.apache.org/zookeeper/zookeeper-3.5.9/
上傳zookeeper 的安裝包到Linux 服務器上面
# 上傳到 /myapp 下
/myapp
解壓apache-zookeeper-3.5.9-bin.tar.gz
tar -zxvf apache-zookeeper-3.5.9-bin.tar.gz
把解壓后的文件移動到指定位置, 這里統一移動到 /myapp/software 目錄下
mv apache-zookeeper-3.5.9-bin /myapp/software/
在 /data 目錄下創建一個文件夾 zookeeper 用來存放zookeeper 的數據文件
cd /data
mkdir zookeeper
復制cp zoo_sample.cfg zoo.cfg
#進入 /myapp/software/apache-zookeeper-3.5.9-bin/conf 目錄
cd /myapp/software/apache-zookeeper-3.5.9-bin/conf
# 復制 zoo_sample.cfg 文件,並重命名為zoo.cfg 否則zookeeper不會生效
cp zoo_sample.cfg zoo.cfg
編輯 zoo.cfg 文件,
修改 dataDir 屬性等於 /tmp/zookeeper 如下第13行所示
# 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.
# 主要是這里<>
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
啟動/關閉/查看狀態 zookeeper 服務
# 1.進入zookeeper安裝目錄的bin 目錄
/myapp/software/apache-zookeeper-3.5.9-bin/bin
# 2. 啟動zookeeper
./zkServer.sh start
# 3. 關閉zookeeper
./zkServer.sh stop
# 4. 查看zookeeper的狀態
./zkServer.sh status
