克隆配置虚拟器hadoop-hive-zookeeper-kafka全流程

1.清理垃圾
[root@hadoop201 ~]# rm -rf anaconda-ks.cfg install.log install.log.syslog

2.选中“克隆虚拟机”：“右键→管理→克隆”
弹窗：
（1）下一步
（2）克隆自：虚拟机中的当前状态
（3）创建完整克隆
（4）虚拟机命名，选择存储位置
（5）完成

3.配置IP
（1）获取地址：vi /etc/udev/rules.d/70-persistent-net.rules
删除第一个eth0，改第二个eth0为eth1
SUBSYSTEM==“net”, ACTION==“add”, DRIVERS=="?", ATTR{address}“00:0c:29:2e:99:a1”, ATTR{type}“1”, KERNEL=="eth", NAME==“eth0”
~
208：“00:0c:29:2e:99:a1”
209：“00:0c:29:78:4f:3f”
（2）修改本机IP：vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:0c:29:b9:4d:21
TYPE=Ethernet
UUID=73c15477-5d31-4956-8be7-2809e1d204db
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static

IPADDR=192.168.1.208
GATEWAY=192.168.1.3
DNS1=192.168.1.3
（3）配置主机名
|- 当前主机名：hostname
hadoop206.cevent.com
|- 修改网络主机配置：vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=hadoop208.cevent.com
|- 修改主机配置：vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.201 hadoop201.cevent.com
192.168.1.202 hadoop202.cevent.com
192.168.1.203 hadoop203.cevent.com

192.168.1.206 hadoop206.cevent.com
192.168.1.207 hadoop207.cevent.com
192.168.1.208 hadoop208.cevent.com
192.168.1.209 hadoop209.cevent.com

4.重启生效
（1）sync
（2）reboot

5.登录报错，修改hosts
路径：C:\Windows\System32\drivers\etc\hosts

Copyright © 1993-2009 Microsoft Corp.

This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

This file contains the mappings of IP addresses to host names. Each

entry should be kept on an individual line. The IP address should

be placed in the first column followed by the corresponding host name.

The IP address and the host name should be separated by at least one

space.

Additionally, comments (such as these) may be inserted on individual

lines or following the machine name denoted by a ‘#’ symbol.

For example:

102.54.94.97 rhino.acme.com # source server

38.25.63.10 x.acme.com # x client host

localhost name resolution is handled within DNS itself.

9.rsync同步文件测试
（1）新建文件
[cevent@hadoop207 module]$ vim rsync.txt
kakaxi
（2）执行同步
[cevent@hadoop207 module]$ rsync -rvl rsync.txt [email protected]:/opt/module/

10.xsync同步任务文件
（1）在/usr/local/bin目录下创建xsync文件，文件内容如下：
#!/bin/bash
#1 获取输入参数的个数，如果没有参数，直接退出,KaTeX parse error: Expected 'EOF', got '#' at position 1: #̲获取参数个数 pcount=#
if((pcount==0)); then
#如果没有参数，返回no args,退出,程序关闭
echo no args;
exit;
fi

#2 获取文件名称:$1获取第一个参数,basename+ 路径1/路径2，获取路径最后一个值名称
p1=$1
fname=basename $p1
echo fname=$fname

#3 获取上级目录到:绝对路径
#获取文件路径:$(dirname $p1)
#cd -P 进入绝对路径 pwd获取路径
pdir=cd -P $(dirname $p1); pwd
echo pdir=$pdir

#4 获取当前用户名称
user=whoami

#5 循环
for((host=207; host<210; host++)); do
#echo $pdir/$fname $user@hadoop$host:$pdirecho---------------hadoop$host.cevent.com ----------------
#拼接路径用户
rsync -rvl $pdir/$fname $user@hadoop$host.cevent.com:$pdir
done

（2）测试同步，默认同步在相同路径下
[cevent@hadoop207 module]$ vim xsync.txt
this is a xsync test!

[cevent@hadoop207 module]$ xsync xsync.txt
fname=xsync.txt
pdir=/opt/module
--------------- hadoop207.cevent.com ----------------
sending incremental file list

sent 32 bytes received 12 bytes 29.33 bytes/sec
total size is 23 speedup is 0.52
--------------- hadoop208.cevent.com ----------------
sending incremental file list
xsync.txt

sent 98 bytes received 31 bytes 258.00 bytes/sec
total size is 23 speedup is 0.18
--------------- hadoop209.cevent.com ----------------
sending incremental file list
xsync.txt

sent 98 bytes received 31 bytes 258.00 bytes/sec
total size is 23 speedup is 0.18

11.xcall脚本，所有主机同时执行命令
（1）在/usr/local/bin目录下创建xcall文件，文件内容如下：
#!/bin/bash
#KaTeX parse error: Expected 'EOF', got '#' at position 1: #̲获取参数个数 #@ 获取所有参数
pcount=$#
if((pcount==0));then
echo no args;
exit;
fi

echo -------------localhost.cevent.com----------
$@for((host=207;host<210;host++));doecho----------hadoop$host.cevent.com---------
ssh hadoop$host.cevent.com $@
done

（2）修改脚本 xcall 具有执行权限
[cevent@hadoop207 bin]$ sudo chmod a+x xcall
[cevent@hadoop207 bin]$ xcall rm -rf /opt/module/rsync.txt
-------------localhost.cevent.com----------
----------hadoop207.cevent.com---------
----------hadoop208.cevent.com---------
----------hadoop209.cevent.com---------

12.core-site.xml配置

[cevent@hadoop207 ~]$ cat /opt/module/hadoop-2.7.2/etc/hadoop/core-site.xml

fs.defaultFS hdfs://hadoop207.cevent.com:8020

    
    
            hadoop.tmp.dir
            /opt/module/hadoop-2.7.2/data/tmp
    

13.hdfs-site.xml配置

[cevent@hadoop207 ~]$ cat /opt/module/hadoop-2.7.2/etc/hadoop/hdfs-site.xml

dfs.replication 1

    
            dfs.namenode.secondary.http-address
            hadoop207.cevent.com:50090
    

14.slaves配置

[cevent@hadoop207 ~]$ vim /opt/module/hadoop-2.7.2/etc/hadoop/slaves
hadoop207.cevent.com
hadoop208.cevent.com
hadoop209.cevent.com

15.yarn-site.xml

[cevent@hadoop207 ~]$ cat /opt/module/hadoop-2.7.2/etc/hadoop/yarn-site.xml

yarn.nodemanager.aux-services mapreduce_shuffle yarn.resourcemanager.hostname hadoop207.cevent.com

16.mapred-site.xml配置

[cevent@hadoop207 ~]$ cat /opt/module/hadoop-2.7.2/etc/hadoop/mapred-site.xml

mapreduce.framework.name yarn

17.同步xsync+xcall测试
[cevent@hadoop207 module]$ xsync hadoop-2.7.2/
[cevent@hadoop207 module]$ xcall cat /opt/module/hadoop-2.7.2/etc/hadoop/slaves
-------------localhost.cevent.com----------

（2）将/opt/module/zookeeper-3.4.10/conf这个路径下的zoo_sample.cfg修改为zoo.cfg
[cevent@hadoop207 zookeeper-3.4.10]$ mv conf/zoo_sample.cfg zoo.cfg
[cevent@hadoop207 zookeeper-3.4.10]$ mv zoo.cfg conf/

（3）创建zkData
[cevent@hadoop207 zookeeper-3.4.10]$ mkdir -p data/zkData
/opt/module/zookeeper-3.4.5/data/zkData

（4）编辑zoo.cfg
[cevent@hadoop207 zookeeper-3.4.10]$ vim conf/zoo.cfg

The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3

Purge task interval in hours

Set to “0” to disable auto purge feature

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=/opt/module/zookeeper-3.4.10/data/zkData

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

（5）启动zookeeper服务器和客户端（需先编辑myid）

（7）配置zookeeper集群zoo.cfg
[cevent@hadoop207 zookeeper-3.4.10]$ vim conf/zoo.cfg
__>最后一行添加如下：

##################cluster#################
server.207=hadoop207.cevent.com:2888:3888
server.208=hadoop208.cevent.com:2888:3888
server.209=hadoop209.cevent.com:2888:3888

（8）启动hadoop：dfs和yarn（不启动hadoop也可以实现，最少启动2个zk）
[cevent@hadoop207 hadoop-2.7.2]$ sbin/start-dfs.sh
[cevent@hadoop207 hadoop-2.7.2]$ sbin/start-yarn.sh
（9）依次启动zookeeper，全部启动查看zkServer.sh status
[cevent@hadoop207 zookeeper-3.4.10]$ bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/module/zookeeper-3.4.10/bin/…/conf/zoo.cfg
