OpenStack Installation Guide for RHEL, CentOS 7

- RHEL, CentOS 7 installation

- Few tips before starting to avoid rocks in your way

• Assign static IP Address to you machine

# vi /etc/sysconfig/network-scripts/ifcfg-enp3s0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.111
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS=8.8.8.8

• Use IPTables instead of Firewalld

# yum install -y iptables*
# systemctl disable firewalld.service
# systemctl stop firewalld.service
# systemctl enable iptables.service
# systemctl enable ip6tables.service
# systemctl start iptables.service
# systemctl start ip6tables.service

• Disable SELinux or set to permissive  

# vi /etc/selinux/config
      SELINUX=disabled

• Disable network manager using network service instead 

# systemctl disable NetworkManager.service
# /etc/init.d/chkconfig netwrok on

• Set  your IP Address in hosts file to avoid puppet service errors

# vi /etc/hosts
     192.168.1.111    el7srv1.localdomain  el7srv1

- Install openstack in fedora 20 (same idea about RHEL7) it's a nice video
