记录Spark集群框架搭建及实验自学心得。
1）打开VMware15Pro，并创建虚拟机
2）选择典型安装
3）设定稍后安装本地已下载好的Centos7系统。
1）载入CentOS7安装文件
2）开启此虚拟机，系统文件自动导入
3）CentOS7系统安装设置
4）考虑到默认安装软件选择是“最小安装”，该方式安装后需要手动添加资源较多，将其更替为“GNOME桌面”
5）用户设置，为了避免后期hadoop集群环境搭建时候反复切换权限用户，可以选择只建立root账户
6）完成安装
1）查看系统自带的jdk
[root@master ~]# java -version
openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)2）查询系统自带的java文件，根据不同的系统版本，输入rpm -qa | grep jdk或者rpm -qa | grep java
[root@master ~]# rpm -qa | grep jdk
java-1.7.0-openjdk-headless-1.7.0.171-2.6.13.2.el7.x86_64
java-1.8.0-openjdk-headless-1.8.0.161-2.b14.el7.x86_64
java-1.7.0-openjdk-1.7.0.171-2.6.13.2.el7.x86_64
java-1.8.0-openjdk-1.8.0.161-2.b14.el7.x86_64
copy-jdk-configs-3.3-2.el7.noarch3）删除noarch文件以外的其他文件，输入rpm -e --nodeps 需要卸载的安装文件名
[root@master ~]# rpm -e --nodeps java-1.7.0-openjdk-headless-1.7.0.171-2.6.13.2.el7.x86_64
[root@master ~]# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.161-2.b14.el7.x86_64
[root@master ~]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.171-2.6.13.2.el7.x86_64
[root@master ~]# rpm -e --nodeps java-1.8.0-openjdk-1.8.0.161-2.b14.el7.x86_644）查看是否已经删除完毕
[root@master ~]# java -version
bash: /usr/bin/java: 没有那个文件或目录jdk下载可分成两种情况：
A.在虚拟机中借助自带的火狐浏览器，将jdk文件下载到虚拟机中
默认下载到Linux系统的下载文件中
B.将jdk直接下载到本地windows系统，然后通过SecureCRT等工具导入虚拟机中，本次试验采用该法
[root@，master ~]# rz
rz waiting to receive.
Starting zmodem transfer. Press Ctrl+C to cancel.
Transferring jdk-8u181-linux-x64.tar.gz...
100% 181295 KB 36259 KB/sec 00:00:05 0 Errors
由于本机直接root用户登录，通过rz命令将jdk载入到/root/Home路径。
将idk安装包转移到系统文件中，可以通过makdir命令，也可以直接定位到安装文件然后手动转移并修改jdk路径，本次试验首先在opt文件下新建一个java文件，然后将jdk放入/opt/java路径下
通过tar -zxvf jdk-8u181-linux-x64.tar.gz命令解压安装包
[root@master ~]# cd /opt/java
[root@master java]# tar -zxvf jdk-8u181-linux-x64.tar.gz1）通过vi /etc/profile或者vim /etc/profile进入profile文件的编辑状态（vim相关编辑命令请自行百度）,也可直接在Linux系统下直接进入/etc/profile路径进行操作。最后，将以下内容复制到profile文件的最后。
#java environment
export JAVA_HOME=/opt/java/jdk1.8.0_181
export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
export PATH=$PATH:${JAVA_HOME}/bin
2）输入source /etc/profile使得刚才的修改生效，同时java -version再次查看java是否已经完成安装
[root@master ~]# source /etc/profile
[root@master ~]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)1）查看是否安装SSH，一般Linux系统默认安装
[root@master ~]# rpm -qa |grep ssh
openssh-clients-7.4p1-16.el7.x86_64
libssh2-1.4.3-10.el7_2.1.x86_64
openssh-7.4p1-16.el7.x86_64
openssh-server-7.4p1-16.el7.x86_642）借助vi /etc/host修改机器名和IP
master 192.168.31.237
slave1 192.168.31.238
slave2 192.168.31.2391）生成公钥与私钥
[root@master ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in y.
Your public key has been saved in y.pub.
The key fingerprint is:
SHA256:+cCJUbTOrw0ON9gjKK7D5rsdNRcWlrNFXxpZpDY2jM4 root@slave2
The key's randomart image is:

|+*+. o . |
+----[SHA256]-----+
[root@master ~]# 2）合并公钥到authorized_keys文件，在master服务器，进入/root/.ssh目录，通过SSH命令合并
[root@master ~]# cd /root/.ssh
[root@master ~]# cat id_rsa.pub>> authorized_keys
[root@master ~]# ssh root@192.168.31.238 cat ~/.ssh/id_rsa.pub >> authorized_keys
[root@master ~]# ssh root@192.168.31.239 cat ~/.ssh/id_rsa.pub >> authorized_keys3）把master服务器的authorized_keys、known_hosts复制到slave服务器的/root/.ssh目录。
scp -r /root/.ssh/authorized_keys root@192.168.31.238:/root/.ssh/
scp -r /root/.ssh/known_hosts root@192.168.31.238:/root/.ssh/
scp -r /root/.ssh/authorized_keys root@192.168.31.239:/root/.ssh/
scp -r /root/.ssh/known_hosts root@192.168.31.239:/root/.ssh/4）验证是否可以免密登陆其他机器

解决方法依具体情况而定，大致分为以下几种：
# 01 修改ifcfg-ens33文件（网络上很多资料提示需要将ens33变更为eth0，其实大可不必）

2）配置hadoop环境变量
[root@master ~]# vim /etc/profile
export HADOOP_HOME=/opt/hadoop/hadoop2.7.2
export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin

From source with checksum 80b9ac6ea66f2b5cf6bc3ce886f3fc67Hbase是基于hadoop提供的分布式文件系统的，所以启动Hbase之前，先确保hadoop在正常运行，另外Hbase还依赖于zookkeeper，本来我们可以用hbase自带的zookeeper，但是我们上面的配置启用的是我们自己的zookeeper集群，所以在启动hbase前，还要确保zokeeper已经正常运行。Hbase可以只在hadoop的某个namenode节点上安装，也可以在所有的hadoop节点上安装，但是启动的时候只需要在一个节点上启动就行了，本例中，我在master、slave1、slave2都安装了Hbase，启动的时候只需要在master上启动就OK。
