在 阿里云ECS 上安裝 CDH6.2

0. pre Install

0.1 ECS 配置
基本配置至少 4核 16GB，比較燒 內存

8核 + 64GB 100GB SSD 5M 寬帶

操作系統看 CDH 官網支持，推薦 RHEL6, RHEL7, CentOs7，總之不推薦 Ali Linux 或者 Amazon Linux

centos7.7

安全組

保證本地可以連接 7180, 22 端口

密鑰，win系統需要再轉換為 pub

xxx.pem密鑰
xxx.pem.pub 密鑰

CDH 6.2

下載路徑
公眾號【大數據1024】輸入 CDH
文件在 2.1 里面列出來了

配置的軟件

SecureCRT
FileZilla

1. 系統環境準備

1.1 設置 ssh 生存時間
避免遠程連接時一會不操作就斷開連接

vi /etc/ssh/sshd_configClientAliveInterval 30ClientAliveCountMax 1800

1.2 設置 時區

timedatectl set-timezone Asia/Shanghai

1.3 設置 主機名

vi /etc/hostnameStock-DMP source /etc/profile

1.4 安裝 基礎包

yum -y install wget yum -y install lrzsz # SecureCRT 上傳下載小文件利器 yum -y install zip unzip yum -y install vim

1.5 關閉 防火墻
阿里云 防火墻 默認是關閉的

systemctl status firewalld systemctl stop firewalld systemctl disable firewalld

1.6 關閉 SELINUX
阿里云 SELINUX 默認是關閉的

vim /etc/selinux/configSELINUX=disabled

1.7 修改 Linux swapping 和虛擬內存
我的機器默認 vm.swappiness = 0
swappiness = 0 表示最大限度使用物理內存，然后才是 swap 空間。有興趣自行搜索調整到合適參數。

vi /etc/sysctl.confvm.swappiness = 0vm.max_map_count=655360 sysctl -p

1.8 禁用 THP (Transparent HugePages)

對于數據庫應用，不推薦使用 THP。主要的原因是這類數據庫大部分訪問內存的方式是分散的，并不是訪問連續的頁面，而這樣的訪問模式,就會造成內存的碎片化。

# 查看 THP 狀態, Always 表示啟用 [root@Stock-DMP soft]# cat /sys/kernel/mm/transparent_hugepage/defrag [always] madvise never # 禁用 THP 并添加到配置文件 [root@Stock-DMP soft]# echo never > /sys/kernel/mm/transparent_hugepage/defrag [root@Stock-DMP soft]# echo never > /sys/kernel/mm/transparent_hugepage/enabled [root@Stock-DMP soft]# echo "echo never > /sys/kernel/mm/transparent_hugepage/defrag" >> /etc/rc.local [root@Stock-DMP soft]# echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local [root@Stock-DMP soft]# chmod +x /etc/rc.d/rc.local # 查看 THP 狀態, Never 表示禁用 [root@Stock-DMP soft]# cat /etc/rc.d/rc.local always madvise [never]

1.9 重啟服務器

reboot -h

2. 安裝環境

2.1 通過 FileZilla 上傳需要的文件
文件大致如下

mkdir -p /soft [root@Stock-DMP CDH6.2]# ll total 2754532 -rw-r--r-- 1 root root 2093332003 Jan 7 16:48 CDH-6.2.1-1.cdh6.2.1.p0.1425774-el7.parcel drwxr-xr-x 2 root root 4096 Jan 7 16:47 cloudera-repos -rw-r--r-- 1 root root 95840 Jan 7 16:33 createrepo-0.9.9-28.el7.noarch.rpm -rw-r--r-- 1 root root 541163520 Jan 7 16:37 mysql-5.7.31-1.el7.x86_64.rpm-bundle.tar -rw-r--r-- 1 root root 1007502 Jan 7 16:37 mysql-connector-java-5.1.47.jar -rw-r--r-- 1 root root 184988341 Jan 7 16:38 oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm -rw-r--r-- 1 root root 32084 Jan 7 16:38 python-deltarpm-3.6-3.el7.x86_64.rpm [root@Stock-DMP CDH6.2]# ll cloudera-repos/ total 1181628 -rw-r--r-- 1 root root 14041 Jan 7 16:38 allkeys.asc -rw-r--r-- 1 root root 10215608 Jan 7 16:38 cloudera-manager-agent-6.2.1-1426065.el7.x86_64.rpm -rw-r--r-- 1 root root 1199718256 Jan 7 16:47 cloudera-manager-daemons-6.2.1-1426065.el7.x86_64.rpm -rw-r--r-- 1 root root 9988 Jan 7 16:47 cloudera-manager-server-6.2.1-1426065.el7.x86_64.rpm -rw-r--r-- 1 root root 10996 Jan 7 16:47 cloudera-manager-server-db-2-6.2.1-1426065.el7.x86_64.rpm -rw-r--r-- 1 root root 1718 Jan 7 16:47 RPM-GPG-KEY-cloudera [root@Stock-DMP CDH6.2]# pwd /soft/CDH6.2

2.2 安裝 JDK
CDH 6.2 支持 jdk1.8
其他版本注意版本對應關系
關于rpm, 可以參考 Linux RPM 命令參數解釋

[root@Stock-DMP CDH6.2]# rpm -ivh oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm warning: oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID b0b19c9f: NOKEY Preparing... ################################# [100%] Updating / installing...1:oracle-j2sdk1.8-1.8.0+update181-1################################# [100%] [root@Stock-DMP CDH6.2]# vi /etc/profile export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera export PATH=.:$PATH:$JAVA_HOME/bin [root@Stock-DMP CDH6.2]# source /etc/profile [root@Stock-DMP CDH6.2]# 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) [root@Stock-DMP CDH6.2]# which java /usr/java/jdk1.8.0_181-cloudera/bin/java

2.3 安裝 Mysql
卸載 centos7 原生的 mariadb

[root@Stock-DMP CDH6.2]# rpm -qa|grep mariadb mariadb-libs-5.5.64-1.el7.x86_64 [root@Stock-DMP CDH6.2]# rpm -e --nodeps mariadb-libs-5.5.64-1.el7.x86_64

執行以下命令

[root@Stock-DMP CDH6.2]# tar -xvf mysql-5.7.31-1.el7.x86_64.rpm-bundle.tar [root@Stock-DMP CDH6.2]# rpm -ivh mysql-community-common-5.7.31-1.el7.x86_64.rpm --force --nodeps [root@Stock-DMP CDH6.2]# rpm -ivh mysql-community-libs-5.7.31-1.el7.x86_64.rpm --force --nodeps [root@Stock-DMP CDH6.2]# rpm -ivh mysql-community-client-5.7.31-1.el7.x86_64.rpm --force --nodeps [root@Stock-DMP CDH6.2]# rpm -ivh mysql-community-server-5.7.31-1.el7.x86_64.rpm --force --nodeps [root@Stock-DMP CDH6.2]# rpm -ivh mysql-community-libs-compat-5.7.31-1.el7.x86_64.rpm --force --nodeps # 驗證 [root@Stock-DMP CDH6.2]# rpm -qa|grep mysql mysql-community-libs-5.7.31-1.el7.x86_64 mysql-community-common-5.7.31-1.el7.x86_64 mysql-community-client-5.7.31-1.el7.x86_64 mysql-community-libs-compat-5.7.31-1.el7.x86_64 mysql-community-server-5.7.31-1.el7.x86_64

如果遇到以下 warning 是由于 yum 安裝了舊版本的 GPG keys 所造成，從 rpm 版本 4.1 后，在安裝或升級軟件包時會自動檢查軟件包的簽名 參考資料

warning: mysql-community-common-5.7.31-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

初始化 Mysql 并獲取初始密碼 farBa5Iys&PL

[root@Stock-DMP CDH6.2]# yum install -y libaio [root@Stock-DMP CDH6.2]# mysqld --initialize --user=mysql [root@Stock-DMP CDH6.2]# cat /var/log/mysqld.log | tail -1 2022-01-07T09:47:06.334066Z 1 [Note] A temporary password is generated for root@localhost: farBa5Iys&PL

啟動 Cloudera Manager

[root@Stock-DMP cloudera-repos]# systemctl start cloudera-scm-server [root@Stock-DMP cloudera-repos]# systemctl enable cloudera-scm-server [root@Stock-DMP cloudera-repos]# systemctl start cloudera-scm-agent [root@Stock-DMP cloudera-repos]# systemctl enable cloudera-scm-agent

通過瀏覽器訪問，初始用戶名 admin，密碼 admin

3. 配置Cloudera Manager

3.1 歡迎頁
3.2 版本選擇
3.3 集群名稱
3.4 集群名稱
選擇當前管理的主機，不然可能無法成功安裝
3.5 依照需求配置服務
后面可以加所以一開始不必要配置很多
3.6 配置數據庫
在 2.3.1 創建 CM 需要的數據庫 操作過
3.7 啟動集群
這里可能會遇到一些問題，可能就是之前配置出了一些問題
3.8 完成
集群仍然有警告信息，由于 HDFS 副本不足和機器數量不足決定的
