Yum install a cluster-based CDH

First, prepare the environment

　　Preparing at least three devices; CentOS7 system;

If you are in the experimental environment, to the virtual machine's memory at least 4G, root recommendations 1T, data disk 1T, because it is a virtual machine, so the root partition and data disk to boldly; if it is in a production environment is the more the better; this time I the experimental environment is three 2G memory, 100G hard drive Tencent cloud host (CentOS7.5), I do not know if you can build a successful, try it;

Second, the database installation

　　Since it is a key yum yum install it in the end;

1、yum install mariadb mariadb-server -y

　　2, start mariadb service, and boot from Kai

　　　　systemctl start mariadb confirm that port 3306 has started

systemctl enable mariadb

　　3, change passwords and configure authorized users

　　　　MariaDB [mysql]> SET PASSWORD FOR 'root'@'localhost'=PASSWORD('123.com');

　 MariaDB [(none)]> CREATE DATABASE scm DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; ## scm database created and designated as the character set utf8mb4, collation is utf8mb4_unicode_ci, ci represents not case-sensitive;

MariaDB [(none)]> CREATE USER 'scm'@'172.21.0.%' IDENTIFIED BY '123.com'; ## creates 'scm'@'172.21.0.%' user

. MariaDB [(none)]> GRANT ALL PRIVILEGES ON scm * TO 'scm'@'172.21.0.%'; scm ownership authorization table in the user database to scm;

MariaDB [(none)]> FLUSH PRIVILEGES; ## make the configuration take effect immediately;

　　4, landing with a newly created user can test whether the normal use;

　　　　(vir-3.5.2) [root@master ~]# mysql -uscm -h172.21.0.3 -p

　　　　Enter password:
　　　　Welcome to the MariaDB monitor. Commands end with ; or \g.
　　　　Your MariaDB connection id is 8
　　　　Server version: 5.5.60-MariaDB MariaDB Server

　　　　Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

　　　　MariaDB [(none)]> use scm;
　　　　Database changed
　　　　MariaDB [scm]> show tables;
　　　　Empty set (0.00 sec)

Third, self image installation address

　　Official mirror installation address ( https://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5.16.1/RPMS/x86_64/ ) due to the source in a foreign country, access will be very slow, so we can self-built source quick installation;

1, install nginx as a web service and start

　　　　yum install nginx -y

　　2, create a profile

　　　　[root@master conf.d]# cat /etc/nginx/conf.d/yum.conf

　　　　{Server
　　　　the listen 80;
　　　　server_name www.zhide666.com;
　　　　the root / Data / yum; gen # specified path
　　　　autoindex on; # open directory browsing

autoindex_exact_size off; # close the file size statistics in detail, so that the file size is displayed MB, GB units, the default is b

　　　　autoindex_localtime on; # turn on the server to display the local time zone file modification date

　　　　}

　　3, create a local source CM, install yum source authoring tools

　　　　yum install yum-utils createrepo yum-plugin-priorities -y

　　　　Access renderings:

　　4, download CDH version stored in the specified path

Fourth, configure yum to create their own source

　　Official yum source: https: //archive.cloudera.com/cm5/redhat/7/x86_64/cm/cloudera-manager.repo

Cm yum own source configuration, not only in its own configuration, but also to the self cm yum source configuration to the two other hosts ;

　　[root@master yum.repos.d]# cat /etc/yum.repos.d/cloudera-manager.repo

　　[cloudera-manager]
　　baseurl=http://www.zhide666.com.cn/cm-5.16.1/
　　gpgkey=http://www.zhide666.com.cn/cm-5.16.1/RPM-GPG-KEY-cloudera
　　enable = 1
　　gpgcheck = 1

验证：

五、安装Cloudera Manager Server端

　　[root@master yum.repos.d]# yum install cloudera-manager-daemons cloudera-manager-server -y

六、各节点安装各个节点安装Cloudera Manager Agent端

　　[root@master yum.repos.d]# yum install cloudera-manager-agent -y

　　[root@node1 yum.repos.d]# yum install cloudera-manager-agent -y

　　[root@node2 yum.repos.d]# yum install cloudera-manager-agent -y
