Oracle VM + centos7.1+openstack kilo Multi-node installation tutorial---Basic Environment configuration (4)

statement: recently in the OpenStack of the Kilo version of the installation, found that there are very few existing web tutorials, and most of the tutorials can not be installed successfully, so write this tutorial. The installation of OpenStack is complex, and this tutorial does not guarantee that it will be installed successfully in different environments. Personal installation tutorials are also prone to errors. At the same time, the installation is in the virtual machine environment, the real installation environment needs to be changed.

The first part of the basic Environment configuration(4)

Next Configure the network configuration of the compute node , Nic 3 is NAT mode

Configuring Networks for network nodes

start Compute Basic settings for network, etc.

Modify hostname

modified to Compute

cp/etc/sysconfig/network-scripts/ifcfg-eth1/etc/sysconfig/network-scripts/ifcfg-eth2cp/etc/sysconfig/ Network-scripts/ifcfg-eth0/etc/sysconfig/network-scripts/ifcfg-eth1

Modify Network Configuration

Vim/etc/sysconfig/network-scripts/ifcfg-eth0

IP address changed to 10.10.10.11

Vim/etc/sysconfig/network-scripts/ifcfg-eth1

IP address changed to 10.20.20.11

Note that the Device name changed to eth1

Vim/etc/sysconfig/network-scripts/ifcfg-eth2

Device name changed to eth2

Reboot re-login hostname has changed

Open network node, configure

Vim/etc/hostname

Change to network

Similarly, the relevant configuration file is rewritten as:

Vim/etc/sysconfig/network-scripts/ifcfg-eht0

Change IP address to 10.10.10.12

Vim/etc/sysconfig/network-scripts/ifcfg-eht1

IP address is 10.20.20.12

DEVICE changed to eth1

Vim/etc/sysconfig/network-scripts/ifcfg-eht2

Delete the ipaddr,netmask,defroute ,

at the same time Bootproto instead None

After the configuration is complete,reboot

test the connectivity of the network

Open Controller Open Compute Open Network

First on the controller node

Ping Compute

On the compute node

Ping www.baidu.com

Installing NTP

First, the Controller,controller provides NTP services for other nodes in the network

Yum Install NTP

To modify a configuration file:

Vim/etc/ntp.conf

Related modifications are (add):

Server Ntp_server iburstrestrict-4 default kod notrap nomodifyrestrict-6 default kod notrap nomodify

Note: Ntp_server is rewritten to provide the address of the NTP service, but there are 1.centos.pool.ntp.org in the default file that can choose to use

Set service boot and start:

Systemctl Enable Ntpd.servicesystemctl start Ntpd.service

Other nodes:

Yum Install NTP

To modify a configuration file:

Vim/etc/ntp.conf

Modify the item (add, the Controller node provides the NTP service):

Server Controller Iburst

Set service boot and start:

Systemctl Enable Ntpd.servicesystemctl start Ntpd.service

relevant verification commands;

Ntpq-c Peersntpq-c Assoc

Note: The main view is whether reach status is up to

Note: The previous article has the relevant image source and SELinux installation, the actual installation, the need for each node to do the following, here is also listed in order to maintain the overall installation logic.

Install the image source

Yum install Http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpmyum Install/HTTP Rdo.fedorapeople.org/openstack-kilo/rdo-release-kilo.rpmyum Upgrade

Note: Foreign servers, domestic visits may occur in a less stable condition

installing selinux

Yum Install Openstack-selinux

At this point, the network and other basic environment to build, the following will be Keystone and other related components of the installation.
