CENTOS installs CDH and Kudu-1


  • CENTOS7.2
  • CDH5.10
  • Kudu1.2

2.1 general

  • This article centos7 2. The process of operating system deploying CDH Enterprise Edition. The installation of Cloudera enterprise data center is mainly divided into four steps:
    • Cluster server configuration, including installing operating system, closing firewall, synchronizing server clock, etc;
    • External database installation
    • Install Cloudera manager;
    • Install CDH cluster;
  • Cluster integrity check, including whether HDFS file system, MapReduce, Hive, etc. can operate normally. This document will focus on the installation of Cloudera manager and CDH, based on the following assumptions:
    • Operating system version: centos7 two
    • MariaDB database version is 10.2.1
    • CM version: CDH 5.10.0
    • CDH version: CDH 5.10.0
    • EC2 user is used to deploy the cluster
    • The installation package of CDH and CM has been downloaded

2.2 preliminary preparation

2.2.1 hostname and hosts configuration

  • All nodes in the cluster can communicate with each other and use static IP addresses. The IP address and host name are configured through / etc/hosts, and the host name is configured through / etc/hostname.
  • Take cm node ( as an example:
    • hostname configuration
    • /The / etc/hostname file is as follows:

Alternatively, the modification can take effect immediately by command

[ec2-user@ip-172-31-2-159 ~]$ sudo hostnamectl  set-hostname ip-172-31-2-159
  • Note: the difference between hostname and REDHAT6 is modified here
  • hosts configuration
    • /The etc/hosts file is as follows: ip-172-31-2-159 ip-172-31-12-108 ip-172-31-5-236 ip-172-31-7-96
  • In the above two steps, configure other nodes in the cluster accordingly

2.2.2 disable SELinux

  • Execute the sudo setenforce0 command on all nodes. Here, use the batch shell to execute:
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh  node.list "sudo setenforce 0"
  • Modify the / etc/selinux/config file for all nodes of the cluster as follows:

2.2.3 close the firewall

  • All nodes in the cluster execute the sudo systemctl stop command. Here, execute the command in batch through the shell as follows:
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh  node.list "sudo systemctl stop firewalld"
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh  node.list "sudo systemctl disable firewalld"
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh  node.list "sudo systemctl status firewalld"

Clock cluster synchronization

In centos7 On the operating system of 2, chrony has been installed by default. Configure chrony clock synchronization, take cm ( service as the local chrony server, and keep the other three servers synchronized with it. Configuration fragment:

  • configuration synchronization
[ec2-user@ ip-172-31-2-159 ~]$ sudo vim  /etc/chrony.conf
server ip-172-31-2-159 iburst
  • Other nodes of the cluster: add the following configuration under the note
[ec2-user@ip-172-31-12-108 ~]$ sudo vim  /etc/chrony.conf
# Use public servers from the pool.ntp.org  project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server ip-172-31-2-159 iburst
  • Restart the chrony service on all machines
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh  node.list "sudo systemctl restart chronyd"
  • Verify that it is always synchronized. Execute the chronycsources command on all nodes, as shown in the following script
[ec2-user@ip-172-31-2-159 ~]$ sh ssh_do_all.sh  node.list "chronyc sources"

2.2.5 configure operating system repo

  • Mount operating system iso files
[ec2-user@ip-172-31-2-159 ~]$ sudo mkdir  /media/DVD1
[ec2-user@ip-172-31-2-159 ~]$ sudo mount -o loop
CentOS-7-x86_64-DVD-1611.iso /media/DVD1/
  • Configure operating system repo
[ec2-user@ip-172-31-2-159 ~]$ sudo vim  /etc/yum.repos.d/local_os.repo
name=CentOS-$releasever - Media
[ec2-user@ip-172-31-2-159 ~]$ sudo yum repolist

2.2.6 installing http services

  • Install httpd service
[ec2-user@ip-172-31-2-159 ~]$ sudo yum -y install  httpd
  • Start or stop the httpd service
[ec2-user@ip-172-31-2-159 ~]$ sudo systemctl  start httpd
[ec2-user@ip-172-31-2-159 ~]$ sudo systemctl stop  httpd
  • After installing httpd, remake the operating system repo and replace it with http, which is convenient for other servers to access
[ec2-user@ip-172-31-2-159 ~]$ sudo mkdir  /var/www/html/iso
[ec2-user@ip-172-31-2-159 ~]$ sudo scp -r  /media/DVD1/* /var/www/html/iso/
[ec2-user@ip-172-31-2-159 ~]$ sudo vim  /etc/yum.repos.d/os.repo
[ec2-user@ip-172-31-2-159 ~]$ sudo yum repolist

2.2.7 installation of MariaDB

Since centros7 uses MariaDB version 5.5.52 by default, version 10.2.1 is used here( http://yum.mariadb.org/10.2.1/centos7-amd64/rpms/ ), download the rpm installation package on the official website:
Download the package locally, put it in the same directory, and execute the createrepo command to generate rpm metadata.
Apache 2 is used here, and the above mariadb10 2.1 move the directory to / var/www/html directory, so that users can access these rpm packages through HTTP.

[ec2-user@ip-172-31-2-159 ~]$ sudo mv mariadb10.2.1  /var/www/html/
  • Installing MariaDB dependencies
[ec2-user@ip-172-31-2-159 ~]$ yum install libaio  perl perl-DBI perl-Module-Pluggable perl-Pod-Escapes perl-Pod-Simple  perl-libs perl-version
  • Make local repo
[ec2-user@ip-172-31-2-159 ~]$ sudo vim  /etc/yum.repos.d/mariadb.repo
name = MariaDB
baseurl = mariadb10.2.1
enable = true
gpgcheck = false
[ec2-user@ip-172-31-2-159 ~]$ sudo yum  repolist 
  • Install MariaDB
[ec2-user@ip-172-31-2-159 ~]$ sudo yum -y install  MariaDB-server MariaDB-client
  • Start and configure MariaDB
[ec2-user@ip-172-31-2-159 ~]$ sudo systemctl  start mariadb
[ec2-user@ip-172-31-2-159 ~]$ sudo /usr/bin/mysql_secure_installation
In order to log into MariaDB to secure it, we'll  need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the  password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):  
OK, successfully used password, moving on...
Setting the root password ensures that nobody can  log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ...  Success!
By default, a MariaDB installation has an  anonymous user, allowing anyone
to log into MariaDB without having to have a user  account created for
them.  This  is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] Y
 ...  Success!
Normally, root should only be allowed to connect  from 'localhost'.  This
ensures that someone cannot guess at the root  password from the network.
Disallow root login remotely? [Y/n] n
 ...  skipping.
By default, MariaDB comes with a database named  'test' that anyone can
access.   This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] Y
 - Dropping  test database...
 ...  Success!
 - Removing  privileges on test database...
 ...  Success!
Reloading the privilege tables will ensure that  all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y
 ...  Success!
Cleaning up...
All done!   If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
