记录Spark集群框架搭建及实验自学心得。
2 准备工作
- VMware 15 Pro
- Centos7
- JDK 1.8
- Hadoop 2.7.2
- SecureCRT version 8.5
- Scala 2.12.7
- Spark 2.3.1
- Zookeeper 3.4.10
- HBase 2.0.2
- Hive 2.3.4
3 安装过程
3.1 在虚拟机中安装CentOS7
3.1.1 虚拟机设置
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。
3.1.2 安装Linux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
3.2 JAVA环境
3.2.1 卸载Linux自带的jdk
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.noarch
3）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_64
4）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
3.2.2 下载并安装最新版本的jdk
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.gz
3.2.3 环境变量设置
1）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)
3.3 SSH免密登陆
3.3.1 准备工作
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_64
2）借助vi /etc/host修改机器名和IP
master 192.168.31.237
slave1 192.168.31.238
slave2 192.168.31.239
3.3.2 设置免密登陆
1）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:
+---[RSA 2048]----+
| +=. .++ |
| .+.o+.= |
| .o=. X |
| .B+oo o |
| o..SE |
| ..oo + |
|. ... + * o |
|.+... = * |
|+*+. 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 [email protected] cat ~/.ssh/id_rsa.pub >> authorized_keys
[root@master ~]# ssh [email protected] cat ~/.ssh/id_rsa.pub >> authorized_keys
3）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 [email protected]:/root/.ssh/
scp -r /root/.ssh/known_hosts [email protected]:/root/.ssh/
scp -r /root/.ssh/authorized_keys [email protected]:/root/.ssh/
scp -r /root/.ssh/known_hosts [email protected]:/root/.ssh/
4）验证是否可以免密登陆其他机器
[root@master ~]# ssh slave1
Last login: Mon Oct 1 16:43:06 2018
[root@slave1 ~]# ssh master
Last login: Mon Oct 1 16:43:58 2018 from slave1
[root@master ~]# ssh slave2
Last login: Mon Oct 1 16:43:33 2018

solution
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）

3.6 Zookeeper安装及环境配置
3.6.1 Zookeeper安装
安装文件解压到/opt/zookeeper路径下。
[root@master ~]# tar -xvf zookeeper-3.4.10.tar.gz
[root@master ~]# mv zookeeper-3.4.10 /opt/zookeeper
[root@master ~]# mv zookeeper-3.4.10 zookeeper3.4
在zookeeper路径下创建数据文件和日志文件。
[root@master ~]# mkdir /opt/zookeeper/data
[root@master ~]# mkdir /opt/zookeeper/log
# 在/opt/zookeeper/data目录下创建myid文件
[root@master ~]# touch myid
[root@master ~]# vi myid
# 设定值为1
1
修改zoo.cfg文件。
[root@master ~]# cd /opt/zookeeper/zookeeper3.4/conf
# 创建zoo.cfg文件
[root@master conf]# cp zoo_sample.cfg zoo.cfg
[root@master conf]# vi zoo.cfg
具体修改如下所示：
# 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=/tmp/zookeeper
# the port at which the clients will connect
# 默认端口是2181，但本机端口被占用，遂变更为2381
clientPort=2381
# 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
quorumListenOnAllIPs=ture
# 新增内容
dataDir=/opt/zookeeper/data
dataLogDir=/opt/zookeeper/log
server.1=master:2888:3888
server.2=slave1:2888:3888
server.3=slave2:2888:3888
将Zookeeper传递给slave1和slave2，/opt/zookeeper/data路径下的myid与zoo.cfg内容须保持一致。
[root@master conf]# scp -r /opt/zookeeper root@slave1:/opt
[root@master conf]# scp -r /opt/zookeeper root@slave2:/opt
3.6.2 Zookeeper环境配置
编辑环境变量。
[root@master ~]# vi /etc/profile
修改内容如下：
export ZK_HOME=/opt/zookeeper/zookeeper3.4
PATH=$PATH:${JAVA_HOME}/bin:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:${SCALA_HOME}/bin:${SPARK_HOME}/bin:${ZK_HOME}/bin:$PATH
使修改生效。
[root@master ~]# source /etc/profile
3.6.3 Zookeeper启动
完成Zookeeper的安装配置后，在每一台机器上启动。注：Zookeeper遵循选举制

3.7 HBase安装及环境配置
3.7.1 HBase安装
将HBase安装包加载至/opt/HBase路径下，并将其解压到当前路径。
[root@master ~]# mkdir /opt/HBase
[root@master ~]# cd /opt/HBase
[root@master HBase]# rz
rz waiting to receive.

[root@master ~]# tar -xvf hbase-2.0.2-bin.tar.gz
3.7.2 配置文件修改
切换到/opt/hbase/hbase-2.0.2/conf路径。
修改hbase-env.sh，在文件中添加以下配置。
export JAVA_HOME=/opt/java/jdk1.8.0_181
export HADOOP_HOME=/opt/hadoop/hadoop-2.7.2
export HBASE_HOME=/opt/HBase/hbase-2.0.2
export HBASE_CLASSPATH=/opt/hadoop/hadoop-2.7.2/etc/hadoop
export HBASE_PID_DIR=/root/hbase/pids
export HBASE_MANAGES_ZK=false
修改hbase-site.xml，在文件中添加以下配置。
<configuration>

</property>
</configuration>
修改regionservers，指定hbase的主从。
master
slave1
slave2
将这些配置传输到其他机器上。
scp -r /opt/HBase root@slave1:/opt
scp -r /opt/HBase root@slave2:/opt
配置环境变量。
[root@master ~]# vi /etc/profile
配置文件内容如下所示：
export HBASE_HOME=/opt/HBase/hbase-2.0.2
export PATH=$PATH:${JAVA_HOME}/bin:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:${SCALA_HOME}/bin:${SPARK_HOME}/bin:${ZK_HOME}/bin:${HBASE_HOME}/bin:$PATH
使配置文件生效。
[root@master ~]# source /etc/profile
查看安装结果。
[root@master ~]# hbase version

3.7.3 启动HBase
Hbase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。

建立必需的文件夹。
# 建立root目录下需要的文件夹
[root@master ~]# mkdir /root/hive
[root@master ~]# mkdir /root/hive/warehouse
# hadoop下新建文件目录
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -mkdir -p /root/hive/
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -mkdir -p /root/hive/warehouse
# 为新建文件目录授权读写能力
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -chmod 777 /root/hive/
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -chmod 777 /root/hive/warehouse
# 检验创建状态
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -ls /root/
