1) using the yum install http service (primary node)
yum -y install httpd
2) The httpd service added to the system since the launch of the service and set the boot
systemctl start httpd # start apache server
systemctl stop httpd # shut down apache server
systemctl enable httpd # Set boot automatically start
systemctl status httpd.service # service httpd status check
3) Download CM5.12.1rpm package (Note: This path contains the CentOS7 version of the rpm package )
（https://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5.12.1/RPMS/x86_64/）
The file is downloaded more than 7 directory under /var/www/html/cm5.12.1
mkdir -p /var/www/html/cm5.12.1
cd /var/www/html/cm5.12.1/
4) Create a local source cm
[root@hadoop101 cm5.12.1]# cd /var/www/html/cm5.12.1/
[root@hadoop101 cm5.12.1]# createrepo .

5) access http://hadoop101.com/cm5.12.1/ local sources confirm whether the normal access
6) local source configuration cm increase in /etc/yum.repo.d/ cm.repo directory file, is written as follows
[root@hadoop101 cm5.12.1]# vim /etc/yum.repos.d/cm.repo
[cmrepo]
name=CM5.12.1
baseurl=http://hadoop101.com/cm5.12.1
gpgcheck=false
enabled=true
7) verify whether the CM source configured successfully
[root@hadoop101 cm5.12.1]# yum repolist
