1. 在根目錄建立zookeeper資料夾(service1、service2、service3都建立)

[root@localhost /]# mkdir zookeeper

通過xshell上傳檔案到service1伺服器:上傳zookeeper-3.4.6.tar.gz到/software資料夾

2.遠端copy將service1下的/software/zookeeper-3.4.6.tar.gz到service2、service3

[root@localhost software]# scp -r /software/zookeeper-3.4.6.tar.gz [email protected]:/software/

[root@localhost software]# scp -r /software/zookeeper-3.4.6.tar.gz [email protected]:/software/

3.copy /software/zookeeper-3.4.6.tar.gz到/zookeeper/目錄(service1、service2、service3都執行)

[root@localhost software]# cp /software/zookeeper-3.4.6.tar.gz /zookeeper/

4.安裝解壓zookeeper-3.4.6.tar.gz(service1、service2、service3都執行)

[root@localhost /]# cd /zookeeper/

[root@localhost zookeeper]# tar -zxvf zookeeper-3.4.6.tar.gz

5.在/zookeeper建立兩個目錄:zkdata、zkdatalog(service1、service2、service3都建立)

[root@localhost zookeeper]# mkdir zkdata

[root@localhost zookeeper]# mkdir zkdatalog

6.進入/zookeeper/zookeeper-3.4.6/conf/目錄

[root@localhost zookeeper]# cd /zookeeper/zookeeper-3.4.6/conf/

[root@localhost conf]# ls

configuration.xsl  log4j.properties  zoo.cfg  zoo_sample.cfg

7. 修改zoo.cfg檔案

# 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=/zookeeper/zkdata

datalogdir=/zookeeper/zkdatalog

# 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.##

## 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

server.1=192.168.2.211:12888:13888

server.2=192.168.2.212:12888:13888

server.3=192.168.2.213:12888:13888

8. 同步修改service2、service3的zoo.cfg配置

9. myid檔案寫入(進入/zookeeper/zkdata目錄下)

[root@localhost /]# cd /zookeeper/zkdata

[root@localhost /]# echo 1 > myid

10. myid檔案寫入service2、service3

echo 2 > myid

echo 3 > myid

11.檢視zk命令:

[root@localhost ~]# cd /zookeeper/zookeeper-3.4.6/bin/

[root@localhost bin]# ls

readme.txt  zkcleanup.sh  zkcli.cmd  zkcli.sh  zkenv.cmd  zkenv.sh  zkserver.cmd  zkserver.sh  zookeeper.out

12.執行zkserver.sh檢視詳細命令:

[root@localhost bin]# ./zkserver.sh

jmx enabled by default

using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg

usage: ./zkserver.sh

13. 在service1、service2、service3分別啟動zk服務

[root@localhost bin]# ./zkserver.sh start

14. jps檢視zk程序

[root@localhost bin]# jps

31483 quorumpeermain

31664 jps

15. 分別在service1、service2、service3檢視zk狀態(可以看到leader和follower節點)

[root@localhost bin]# ./zkserver.sh status

jmx enabled by default

using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg

mode: follower

[root@localhost bin]# ./zkserver.sh status

jmx enabled by default

using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg

mode: leader

16. 看到leader和follower節點已經安裝成功。

訓練集 驗證集 測試集

訓練集loss 驗證集loss 測試集loss 乙個好的網路,二者的差距應該是很低的。但一般情況下因為網路不可避免地存在一定程度上的過擬合,所以肯定是train loss低於test lost,但如果低太多,就得考慮是過擬合的問題還是因為樣本的特徵空間不統一的問題。驗證集基本是在每個epoch完成後...

訓練集,驗證集,測試集

普通引數就是可以被梯度下降所更新的,也就是訓練集所更新的引數。超引數是指訓練開始之前設定的引數,不在梯度下降的更新範圍內,比如網路層數 網路節點數 迭代次數 學習率等等 1.訓練集 確定模型後,用於訓練普通引數 2.驗證集 交叉驗證集cv 驗證集在每個epoch訓練完成後,用來測試一下當前模型的準確...
