I make the binary executable using the Linux chmod command:
[root@hc2nn tmp]# chmod 755 cloudera-manager-installer.bin
[root@hc2nn tmp]# ls -l cloudera-manager-installer.bin
-rwxr-xr-x. 1 root root 510569 Aug 30 19:11 cloudera-manager-installer.bin
Before running the installation, I disable SELinux on each server and reboot the server. I do this as the root user:
vi /etc/selinux/config
I set the SELINUX value to “disabled”:
SELINUX=disabled
[root@hc2nn tmp]# reboot
Then I execute the Cloudera manager binary and follow the prompts until I can access the installation web
browser at http://hc2nn:7180/. I log in as the user admin with a password of “admin” to see a list of the packages
that I can install. I click Continue.
At the next page, I enter the fully qualified domain names (FQDN) hostnames on which I intend to install, in the
form as follows:
192.168.1.103 hc2nn.semtech-solutions.co.nz hc2nn
Then I click the Search button to allow the manager to obtain details about the servers. When the servers are
located, I see “host ready” messages similar to those shown in Figure 8-10 .
