      2. # groupadd [group name]
      3. # useradd [user id] -g [group name] -d /home/[user id] -s /bin/bash
      4. # passwd
   2. make added users password-less and root-privileged: http://devtainer.blogspot.com/2011/03/sudo-in-centos_16.html
      1. # su -
      2. # chmod u+w /etc/sudoers
      3. register user by setting '[user id]    ALL=(ALL)    NOPASSWD: ALL'

         

      4. # chmod u-w /etc/sudoers
   3. open port 7180: http://www.cyberciti.biz/faq/howto-rhel-linux-open-port-using-iptables
      1. # vi /etc/sysconfig/iptables
      2. add this line '-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport [port number] -j ACCEPT'
      3. # /etc/init.d/iptables restart
      4. # iptables -L –n
   4. Disable iptables: http://www.cyberciti.biz/faq/disable-linux-firewall-under-centos-rhel-fedora/
      1. # service iptables save
      2. # service iptables stop
      3. # chkconfig iptables off
   5. check whether 'ping archive.cloudera.com' works: it didn't work, but it's okay to install
   6. configure DNS and reverse DNS properly: network manager's work

   7. disable SELinux: http://wiki.centos.org/HowTos/SELinux
      1. # sestatus
      2. # vi /etc/selinux/config
      3. set 'SELINUX=disabled'

         

      4. # reboot
   8. check /etc/hosts
      1. if there is no line '10.1.20.xy ha01.something.com ha01' for ha01 and '10.1.20.zw ha02.something.com ha02' for ha02, scm installer doesn't work properly

         

      2. before modifying /etc/hosts: IP Adress has wrong information 127.0.0.1 for ha01.something.com

         

2. execute scm installer
   1. $ wget http://archive.cloudera.com/scm/installer/latest/scm-installer.bin
   2. $ chmod u+x ./scm-installer.bin
   3. $ sudo ./scm-installer.bin
   4. If failed, execute it again then It'll work
3. Connect to [server name or ip]:7180
