1.准备的工具:
软件安装包：
ossutil64工具下载:
1 [root@hadoop001 ~]# wget http://gosspublic.alicdn.com/ossutil/1.6.3/ossutil64 2 --2019-06-29 09:48:21-- http://gosspublic.alicdn.com/ossutil/1.6.3/ossutil64 3 Resolving gosspublic.alicdn.com (gosspublic.alicdn.com)... 205.204.104.233, 205.204.104.242 4 Connecting to gosspublic.alicdn.com (gosspublic.alicdn.com)|205.204.104.233|:80... connected. 5 HTTP request sent, awaiting response... 200 OK 6 Length: 9741374 (9.3M) [application/octet-stream] 7 Saving to: ‘ossutil64’ 8 9 100%[=========================================================================================================================================================>] 9,741,374 3.21MB/s in 2.9s 10 11 2019-06-29 09:48:25 (3.21 MB/s) - ‘ossutil64’ saved [9741374/9741374]
软件安装包我事先收集好放在OSS上存储，通过ossutil64命令行工具下载到本机上
[root@hadoop001 ~]# ./ossutil64 cp -r oss://20190616 /root Succeed: Total num: 9, size: 3,701,212,166. OK num: 9(download 9 objects).
安装所需软件如下
1 [root@hadoop001 cdh5.16.1]# ll 2 total 3614496 3 -rw-r--r-- 1 root root 2127506677 Jun 29 10:04 CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel 4 -rw-r--r-- 1 root root 41 Jun 29 10:04 CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel.sha1 5 -rw-r--r-- 1 root root 841524318 Jun 29 10:04 cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz 6 -rw-r--r-- 1 root root 173271626 Jun 29 10:04 jdk-8u45-linux-x64.gz 7 -rw-r--r-- 1 root root 66538 Jun 29 10:04 manifest.json 8 -rw-r--r-- 1 root root 548193637 Jun 29 10:04 mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz 9 -rw-r--r-- 1 root root 1007502 Jun 29 10:05 mysql-connector-java-5.1.47.jar 10 -rw-r--r-- 1 root root 9641827 Jun 29 10:05 ossutil64
阿里云服务器:
购买4台阿里云抢占式服务器，一小时大概8毛钱，学习成本还算挺低得了，使用完毕还可以随时释放掉；拿来练手是不错的选择。
2.依赖环境部署安装:
centos7.4
1.进行SSH免登陆设置
ssh免登陆设置方便后续文件进行scp命令分发
使用root用户进入家目录.ssh文件夹进行如下操作
1 [root@hadoop001 .ssh]# ssh-keygen -t rsa 2 Generating public/private rsa key pair. 3 Enter file in which to save the key (/root/.ssh/id_rsa): 4 Enter passphrase (empty for no passphrase): 5 Enter same passphrase again: 6 Your identification has been saved in /root/.ssh/id_rsa. 7 Your public key has been saved in /root/.ssh/id_rsa.pub. 8 The key fingerprint is: 9 SHA256:QLf04jdE2pLmSEyWlbg/7YKlmuVFAeNAEZE24HKePpA root@hadoop001 10 The key's randomart image is: 11 +---[RSA 2048]----+ 12 | .o*=*++.. | 13 | . +Bo=.B | 14 |. o. .=.O + | 15 | = . ..* = | 16 |E o ..S.o | 17 | o .+... | 18 | o .+.o | 19 | . +o.. . | 20 | o.. . | 21 +----[SHA256]-----+
把生成的id_rsa.pub更名为authorized_keys，批量分发到其他主机上
1 [root@hadoop001 .ssh]# cat id_rsa.pub >> /root/authorized_keys 2 [root@hadoop001 .ssh]# cd .. 3 [root@hadoop001 ~]# ll 4 total 9524 5 -rw-r--r-- 1 root root 396 Jun 29 11:05 authorized_keys 6 drwxr-xr-x 2 root root 4096 Jun 29 10:05 cdh5.16.1 7 -rwxr-xr-x 1 root root 9741374 Jun 20 15:57 ossutil64 8 [root@hadoop001 ~]# scp id_rsa.pub hadoop003:/root/.ssh/ 9 root@hadoop003's password: 10 id_rsa.pub: No such file or directory 11 [root@hadoop001 ~]# scp authorized_keys hadoop003:/root/.ssh/ 12 root@hadoop003's password: 13 authorized_keys 100% 396 1.5MB/s 00:00 14 [root@hadoop001 ~]# scp authorized_keys hadoop004:/root/.ssh/ 15 root@hadoop004's password: 16 authorized_keys
2.hosts文件设置
1 [root@hadoop001 ~]# vi /etc/hosts
进入hosts文件添加集群主机
1 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 2 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 3 # cdh 4 172.31.188.179 hadoop001 5 172.31.188.180 hadoop002 6 172.31.188.181 hadoop003 7 172.31.188.182 hadoop004 8 ~ 9 ~
测试集群主机是否连通，四台主机均访问正常
1 [root@hadoop001 cdh5.16.1]# ping hadoop002 2 PING hadoop002 (172.31.188.180) 56(84) bytes of data. 3 64 bytes from hadoop002 (172.31.188.180): icmp_seq=1 ttl=64 time=0.146 ms 4 ^Z 5 [2]+ Stopped ping hadoop002 6 [root@hadoop001 cdh5.16.1]# ping hadoop003 7 PING hadoop003 (172.31.188.181) 56(84) bytes of data. 8 64 bytes from hadoop003 (172.31.188.181): icmp_seq=1 ttl=64 time=0.295 ms 9 ^Z 10 [3]+ Stopped ping hadoop003 11 [root@hadoop001 cdh5.16.1]# ping hadoop004 12 PING hadoop004 (172.31.188.182) 56(84) bytes of data. 13 64 bytes from hadoop004 (172.31.188.182): icmp_seq=1 ttl=64 time=0.331 ms 14 ^Z 15 [4]+ Stopped ping hadoop004
通过scp命令把修改好的hosts文件分发到其他三台主机上
1 [root@hadoop001 ~]# scp /etc/hosts hadoop002:/etc 2 hosts 100% 264 1.2MB/s 00:00 3 [root@hadoop001 ~]# scp /etc/hosts hadoop003:/etc 4 hosts 100% 264 1.2MB/s 00:00 5 [root@hadoop001 ~]# scp /etc/hosts hadoop004:/etc 6 hosts 100% 264 1.0MB/s 00:00
JAVA安装
解压java压缩包
1 [root@hadoop001 ~]# tar -xzvf cdh5.16.1/jdk-8u45-linux-x64.gz -C /usr/java/
添加java全局变量
#env export JAVA_HOME=/usr/java/jdk1.8.0_45 export PATH=$PATH:$JAVA_HOME/bin
执行soure命令，使全局变量生效
1 [root@hadoop001 ~]# source /etc/profile 2 [root@hadoop001 ~]# java -version 3 java version "1.8.0_45" 4 Java(TM) SE Runtime Environment (build 1.8.0_45-b14) 5 Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
