在 CentOS7 docker 鏡像上安裝 zookeeper-3.4.11 服務

獲取centos 鏡像html

執行docker 命令，運行docker容器docker

docker run -t -i --name='centos' -p 8080:80 -d 2d194b392dd1 /bin/bash

進入docker容器:安裝jdkapache
建立 /usr/local/services/zookeeper 文件夾：vim
```
mkdir -p /usr/local/services/zookeeper
```
進入到 /usr/local/services/zookeeper 目錄中：centos
```
cd /usr/local/services/zookeeper
```

下載 zookeeper-3.4.11.tar.gz：bash

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz

解壓縮 zookeeper-3.4.11.tar.gz：ide
```
tar -zxvf zookeeper-3.4.11.tar.gz
```
進入到 /usr/local/services/zookeeper/zookeeper-3.4.11/conf 目錄中：ui
```
cd zookeeper-3.4.11/conf/
```
複製 zoo_sample.cfg 文件的並命名爲爲 zoo.cfg：this
```
cp zoo_sample.cfg zoo.cfg
```

用 vim 打開 zoo.cfg 文件並修改其內容爲以下：idea

# 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

# 數據文件夾
dataDir=/usr/local/services/zookeeper/zookeeper-3.4.11/data

# 日誌文件夾
dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.11/logs

# the port at which the clients will connect
# 客戶端訪問 zookeeper 的端口號
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

保存並關閉 zoo.cfg 文件:

用 vim 打開 /etc/ 目錄下的配置文件 profile： vim /etc/profile 並在其尾部追加以下內容：

# idea - zookeeper-3.4.11 config start - 2016-09-08

export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.11/
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH

# idea - zookeeper-3.4.11 config start - 2016-09-08

使 /etc/ 目錄下的 profile 文件便可生效：
```
source /etc/profile
```
啓動 zookeeper 服務：
```
zkServer.sh start
```
如打印以下信息則代表啓動成功： ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfg Starting zookeeper ... STARTED
查詢 zookeeper 狀態：
```
zkServer.sh status
```
關閉 zookeeper 服務：
```
zkServer.sh stop
```
如打印以下信息則代表成功關閉： ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfg Stopping zookeeper ... STOPPED
重啓 zookeeper 服務：
```
zkServer.sh restart
```
如打印以下信息則代表重啓成功： ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfg ZooKeeper JMX enabled by default Using config: /usr/local/services/zookeeper/zookeeper-3.4.11/bin/../conf/zoo.cfg Stopping zookeeper ...
