安装Spark+hadoop，spark、hadoop分布式集群搭建...(亲自搭建过！！)
首先说一下我所用的版本：
spark-2.1.1-bin-hadoop2.7.tgz
hadoop-2.7.3.tar.gz
jdk-8u131-linux-x64.rpm
- 1
- 2
- 3
我们实验室有4台服务器：每个节点硬盘：300GB，内存：64GB。四个节点的hostname分别是master，slave01，slave02，slave03。
我用的是Spark做并行计算，用HDFS作为数据的分布式存储，这样的话就得安装hadoop利用里面的HDFS。如果你不用hadoop的话可以直接跳到第7步，直接安装spark即可！
1。先装java1.8环境：给各个节点上传jdk-8u131-linux-x64.rpm到/home里面。用rpm安装。
[root@localhost home]# rpm -ivh jdk-8u131-linux-x64.rpm

如上：java1.8 安装成功！！
2。集群核准时间：(如果集群时间一致的话，此步略过！)
时间必须同步，因为节点之间要发送心跳，如果时间不一致的话，会产生错误。
用date -s 命令也行！(下面是ntp服务器来同步时间)
##在每个节点上执行安装ntp服务
[hadoop@master ~]$ sudo yum install -y ntp
##在每个节点上同时执行`sudo ntpdate us.pool.ntp.org`
[hadoop@master ~]$ sudo ntpdate us.pool.ntp.org
5 Oct 18:19:41 ntpdate[2997]: step time server 138.68.46.177 offset -6.006070 sec

或者也可以在某个节点上启动一个ntp服务器：
##在每个节点上执行安装ntp服务
[hadoop@master ~]$ sudo yum install -y ntp
##在192.168.2.219节点上执行`sudo ntpdate us.pool.ntp.org`把这个节点作为ntp同步服务器
[hadoop@master ~]$ sudo ntpdate us.pool.ntp.org
5 Oct 18:19:41 ntpdate[2997]: step time server 138.68.46.177 offset -6.006070 sec
##在各个节点上开启ntp服务
[hadoop@master ~]$ sudo service ntpd start
Redirecting to /bin/systemctl start ntpd.service
##在其他节点上同步192.168.2.219节点ntp服务器上的时间。
[hadoop@slave01 ~]$ sudo ntpdate 192.168.2.219
5 Oct 18:27:45 ntpdate[3014]: adjust time server 192.168.147.6 offset -0.001338 sec

3。添加用户hadoop：
[root@localhost etc]# useradd -m hadoop -s /bin/bash
useradd: user 'hadoop' already exists
[root@localhost etc]# passwd hadoop
Changing password for user hadoop.
New password:
BAD PASSWORD: The password fails the dictionary check - it is too simplistic/systematic
Retype new password:
passwd: all authentication tokens updated successfully.
[root@localhost etc]# su - hadoop
[hadoop@localhost ~]$

4。给hadoop用户增加管理员权限，方便部署
[root@localhost ~]#visudo
- 1
找到 root ALL=(ALL) ALL 这行（应该在第98行，可以先按一下键盘上的 ESC 键，然后输入 :98 (按一下冒号，接着输入98，再按回车键)，可以直接跳到第98行 ），然后在这行下面增加一行内容：hadoop ALL=(ALL) ALL （当中的间隔为tab），如下图所示：
5。SSH无密通信：
[root@master .ssh]#su - hadoop
[hadoop@master ~]$
[hadoop@master ~]$ ssh localhost # 如果没有该目录，先执行一次ssh localhost
[hadoop@master ~]$ cd ~/.ssh
[hadoop@master ~]$ rm ./id_rsa* # 删除之前生成的公匙（如果有）
[hadoop@master ~]$ ssh-keygen -t rsa # 一直按回车就可以
让 Master 节点需能无密码 SSH 本机，在 Master 节点上执行：
[hadoop@master .ssh]$ cat ./id_rsa.pub >> ./authorized_keys
完成后可执行 ssh Master 验证一下（可能需要输入 yes，成功后执行 exit 返回原来的终端）。接着在 master 节点将上公匙传输到 slave01,slave02,slave03 节点：
[hadoop@master .ssh]$ scp ~/.ssh/id_rsa.pub hadoop@slave01:/home/hadoop/
[hadoop@master .ssh]$ scp ~/.ssh/id_rsa.pub hadoop@slave02:/home/hadoop/
[hadoop@master .ssh]$ scp ~/.ssh/id_rsa.pub hadoop@slave03:/home/hadoop/
接着在 slave01,slave02,slave03节点上，将 ssh 公匙加入授权：【分别在其他三个节点上执行以下命令：】
[hadoop@slave03 ~]$ mkdir ~/.ssh
[hadoop@slave03 ~]$ cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
[hadoop@slave03 ~]$ rm ~/id_rsa.pub
然后在master上执行ssh slave01 但是还是不行解决方法：

常见免密码登录失败分析
配置问题
检查配置文件/etc/ssh/sshd_config是否开启了AuthorizedKeysFile选项
检查AuthorizedKeysFile选项指定的文件是否存在并内容正常
目录权限问题
~权限设置为700
~/.ssh权限设置为700
~/.ssh/authorized_keys的权限设置为600
sudo chmod 700 ~
sudo chmod 700 ~/.ssh
sudo chmod 600 ~/.ssh/authorized_keys

6。安装hadoop：
下面是hosts文件内容：
192.168.2.189 slave01
192.168.2.240 slave02
192.168.2.176 slave03
192.168.2.219 master
hadoop-2.7.3.tar.gz放在~下。【一般安装文件都放在~下面】
我们选择将 Hadoop 安装至 /usr/local/ 中：
[hadoop@master ~]$ sudo tar -zxf ~/hadoop-2.7.3.tar.gz -C /usr/local # 解压到/usr/local中
[hadoop@master ~]$ cd /usr/local/
[hadoop@master ~]$ sudo mv ./hadoop-2.7.3/ ./hadoop # 将文件夹名改为hadoop
[hadoop@master ~]$ sudo chown -R hadoop:hadoop ./hadoop # 修改文件权限

Hadoop 解压后即可使用。输入如下命令来检查 Hadoop 是否可用，成功则会显示 Hadoop 版本信息：
[hadoop@master local]$ cd /usr/local/hadoop
[hadoop@master hadoop]$ ./bin/hadoop version
Hadoop 2.7.3

6.1。 Hadoop单机配置(非分布式) ，注：先把一个节点的hadoop装好后，然后再依次拷贝到其他的节点上。
Hadoop 默认模式为非分布式模式，无需进行其他配置即可运行。非分布式即单 Java 进程，方便进行调试。
现在我们可以执行例子来感受下 Hadoop 的运行。Hadoop 附带了丰富的例子（运行 ./bin/hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.3.jar 可以看到所有例子），包括 wordcount、terasort、join、grep 等。
在此我们选择运行 grep 例子，我们将 input 文件夹中的所有文件作为输入，筛选当中符合正则表达式 dfs[a-z.]+ 的单词并统计出现的次数，最后输出结果到 output 文件夹中。
[hadoop@master hadoop]$ cd /usr/local/hadoop
[hadoop@master hadoop]$ mkdir ./input
[hadoop@master hadoop]$ cp ./etc/hadoop/*.xml ./input # 将配置文件作为输入文件
[hadoop@master hadoop]$./bin/hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-examples-*.jar grep ./input ./output 'dfs[a-z.]+'
[hadoop@master hadoop]$ cat ./output/* # 查看运行结果

6.2。修改/usr/local/hadoop/etc/hadoop/slaves:这里配置的是三个运行节点，master节点只做master不作为运行节点。
[hadoop@master hadoop]$ vi slaves #里面内容是：
slave01
slave02
slave03

<property>
<name>hadoop.tmp.dirname>
<value>/usr/local/hadoop/tmpvalue>
<description>Abase for other temporary directories.description>
property>

6.7。配置好后，将 master 上的 /usr/local/Hadoop 文件夹复制到各个节点上。在 master 节点上执行：
之前有跑过伪分布式模式，建议在切换到集群模式前先删除之前的临时文件。
[hadoop@master ~]$cd /usr/local
[hadoop@master ~]$sudo rm -r ./hadoop/tmp # 删除 Hadoop 临时文件
[hadoop@master ~]$sudo rm -r ./hadoop/logs/* # 删除日志文件
[hadoop@master ~]$tar -zcf ~/hadoop.master.tar.gz ./hadoop # 先压缩再复制
[hadoop@master ~]$cd ~
[hadoop@master ~]$scp ./hadoop.master.tar.gz slave01:/home/hadoop
[hadoop@master ~]$scp ./hadoop.master.tar.gz slave02:/home/hadoop
[hadoop@master ~]$scp ./hadoop.master.tar.gz slave03:/home/hadoop

6.8。在各个节点执行：
在 slave01 节点上执行：
[hadoop@slave01 ~]$ sudo rm -r /usr/local/hadoop # 删掉旧的（如果存在）
[hadoop@slave01 ~]$ sudo tar -zxf ~/hadoop.master.tar.gz -C /usr/local
[hadoop@slave01 ~]$ sudo chown -R hadoop /usr/local/hadoop
- 1
- 2
- 3
在 slave02 节点上执行：
[hadoop@slave02 ~]$ sudo rm -r /usr/local/hadoop # 删掉旧的（如果存在）
[hadoop@slave02 ~]$ sudo tar -zxf ~/hadoop.master.tar.gz -C /usr/local
[hadoop@slave02 ~]$ sudo chown -R hadoop /usr/local/hadoop
- 1
- 2
- 3
在 slave03 节点上执行：
[hadoop@slave03 ~]$ sudo rm -r /usr/local/hadoop # 删掉旧的（如果存在）
[hadoop@slave03 ~]$ sudo tar -zxf ~/hadoop.master.tar.gz -C /usr/local
[hadoop@slave03 ~]$ sudo chown -R hadoop /usr/local/hadoop
- 1
- 2
- 3
6.9。首次启动需要先在 Master 节点执行 NameNode 的格式化：
[hadoop@master ~]$ hdfs namenode -format #首次运行需要执行初始化，之后不需要
- 1
6.10。CentOS系统需要关闭防火墙
CentOS系统默认开启了防火墙，在开启 Hadoop 集群之前，需要关闭集群中每个节点的防火墙。有防火墙会导致 ping 得通但 telnet 端口不通，从而导致 DataNode 启动了，但 Live datanodes 为 0 的情况。
在 CentOS 中，可以通过如下命令关闭防火墙：
在 CentOS 6.x 中，可以通过如下命令关闭防火墙：
sudo service iptables stop # 关闭防火墙服务
sudo chkconfig iptables off # 禁止防火墙开机自启，就不用手动关闭了
Shell 命令
若用是 CentOS 7，需通过如下命令关闭（防火墙服务改成了 firewall）：
systemctl stop firewalld.service # 关闭firewall
systemctl disable firewalld.service # 禁止firewall开机启动

6.11。接着可以启动 hadoop 了，启动需要在 master 节点上进行：
注意修改：vi /usr/local/hadoop/etc/hadoop/hadoop-env.sh ，
把export JAVA_HOME=${JAVA_HOME}改为：export JAVA_HOME=/usr/java/jdk1.8.0_131/
在/usr/local/hadoop/sbin 启动hadoop ./start-all.sh
[hadoop@master sbin]$ ./start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [master]

6.12. 打开hadoop WEBUI
在浏览器中输入http://192.168.2.219:50070 【注意浏览器要与192.168.2.219为局域网】
6.13。执行分布式实例
首先创建 HDFS 上的用户目录：
[hadoop@master hadoop]$ hdfs dfs -mkdir -p /user/hadoop
将 /usr/local/hadoop/etc/hadoop 中的配置文件作为输入文件复制到分布式文件系统中：
[hadoop@master hadoop]$ hdfs dfs -mkdir input
[hadoop@master hadoop]$ hdfs dfs -put /usr/local/hadoop/etc/hadoop/*.xml input
- 1
- 2
- 3

- 5
通过查看 DataNode 的状态（占用大小有改变），输入文件确实复制到了 DataNode 中，如下图所示：
接着就可以运行 MapReduce 作业了：【注意运行前要保证节点时间一致】
####命令：
hadoop jar /usr/local/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-*.jar grep input output 'dfs[a-z.]+'

####执行过程运行的log如下：
[hadoop@master hadoop]$ hadoop jar /usr/local/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-*.jar grep input output 'dfs[a-z.]+'

运行时的输出信息与伪分布式类似，会显示 Job 的进度。
可能会有点慢，但如果迟迟没有进度，比如 5 分钟都没看到进度，那不妨重启 Hadoop 再试试。
6.14。关闭 Hadoop 集群也是在 Master 节点上执行的：./sbin/stop-all.sh 即可
[hadoop@master sbin]$ stop-all.sh
This script is Deprecated. Instead use stop-dfs.sh and stop-yarn.sh
Stopping namenodes on [master]
master: stopping namenode
slave01: stopping datanode
slave03: stopping datanode
slave02: stopping datanode
Stopping secondary namenodes [0.0.0.0]
0.0.0.0: stopping secondarynamenode

stopping resourcemanager
slave01: stopping nodemanager
slave02: stopping nodemanager
slave03: stopping nodemanager
slave01: nodemanager did not stop gracefully after 5 seconds: killing with kill -9
slave02: nodemanager did not stop gracefully after 5 seconds: killing with kill -9
slave03: nodemanager did not stop gracefully after 5 seconds: killing with kill -9

附录：增加一个master节点作为slaves ，这样运行节点就变成4个了，进入/usr/local/hadoop/etc/hadoop/修改slaves为：
master
slave01
slave02
slave03
$PWD就是当前目录，把此目录的slaves拷贝到其他三个节点上进行覆盖。
[hadoop@master hadoop]$ scp slaves hadoop@slave01:$PWD
[hadoop@master hadoop]$ scp slaves hadoop@slave02:$PWD
[hadoop@master hadoop]$ scp slaves hadoop@slave03:$PWD

再启动：
[hadoop@master hadoop]$ ./sbin/start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

至此hadoop安装完成！！！！
7。安装spark
先把spark-2.1.1-bin-hadoop2.7.tgz传到~里。
执行命令：
[hadoop@master ~]$ sudo tar -zxf ~/spark-2.1.1-bin-hadoop2.7.tgz -C /usr/local/
[hadoop@master ~]$ cd /usr/local
[hadoop@master ~]$ sudo cp ./spark-2.1.1-bin-hadoop2.7.tgz/ ./spark
[hadoop@master ~]$ sudo chown -R hadoop:hadoop ./spark

7.1。 在/usr/local/spark/conf里，修改spark-env.sh添加：
export JAVA_HOME=/usr/java/jdk1.8.0_131
export SPARK_MASTER_IP=192.168.2.219
export SPARK_MASTER_PORT=7077

7.2。在/usr/local/spark/conf里，添加内容到slaves，这里有4个运行节点把master也算进去了，master既做管理又做计算
[hadoop@master conf]$ cat slaves

7.3。 配置好后，将Master主机上的/usr/local/spark文件夹复制到各个节点上。在Master主机上执行如下命令：
[hadoop@master local]$ cd /usr/local/
压缩spark包
[hadoop@master local]$ tar -zcf ~/spark.master.tar.gz ./spark
[hadoop@master local]$ cd ~
把spark压缩包远程传到其他节点
[hadoop@master local]$ scp ./spark.master.tar.gz slave01:/home/hadoop
[hadoop@master local]$ scp ./spark.master.tar.gz slave02:/home/hadoop
[hadoop@master local]$ scp ./spark.master.tar.gz slave03:/home/hadoop
