The Construction of basic Environment of openstack O Edition

Configuration instructions:

Controller IP:192.168.0.111

Compute IP: 192.168.0.112

1. Network configuration.

Controller

DEVICE=ens33

ONBOOT=yes

IPADDR=192.168.0.111

PREFIX0=24

GATEWAY=192.168.0.254

DNS1=192.168.0.254

Compute

DEVICE=ens33

ONBOOT=yes

IPADDR=192.168.0.112

PREFIX0=24

GATEWAY=192.168.0.254

DNS1=192.168.0.254

Shut down iptables and selinux on both servers

(1) turn off the firewall

Systemctl stop firewalld.service

Systemctl disable firewalld.service

(2) close selinux

Setenforce 0

[root@compute ~] # setenforce 0

[root@compute ~] # cat / etc/selinux/config

SELINUX=disabled

SELINUXTYPE=targeted

Construction of 2.NTP Service

Controller

Install the chrony time synchronization service (the system defaults to installation), or install it if it is not installed.

[root@controller ~] # rpm-qa | grep chrony

Chrony-2.1.1-4.el7.centos.x86_64

[root@controller ~] # yum-y install chrony

[root@controller ~] # vi / etc/chrony.conf

After installation, you need to modify the configuration file, as follows:

Start the ntp service

[root@controller ~] # systemctl start chronyd.service starts the ntp service

[root@controller ~] # systemctl status chronyd.service to view time synchronization status

[root@controller ~] # chronyc sources-v View time synchronization sources

[root@controller ~] # chronyc sourcestats-v View time synchronization Source status

Installation and deployment of Compute ntp

Install the same as above, modify the configuration file after installation

[root@compute ~] # vi / etc/chrony.conf

Start the service and see if it is working as above.

# # installation and deployment of controller Openstack package # #

I. MySQL service

[root@controller ~] # yum-y install mariadb mariadb-server python2-PyMySQL install 46 packages

[root@controller ~] # cd / etc/my.cnf.d/

[root@controller my.cnf.d] # vi mariadb-openstack.cnf

[root@controller my.cnf.d] # cat mariadb-openstack.cnf

[mysqld]

Default-storage-engine = innodb

Innodb_file_per_table

Collation-server = utf8_general_ci

Init-connect = 'SET NAMES utf8'

Character-set-server = utf8

Bind-address = 192.168.0.111

[root@controller ~] # systemctl enable mariadb.service

[root@controller ~] # systemctl start mariadb.service

[root@controller ~] # netstat-anpult | grep mysqld

Tcp 0 0 192.168.0.111:3306 0.0.0.0: LISTEN 2990/mysqld

Initialize the database

[root@controller ~] # mysql_secure_installation

Enter current password for root (enter for none): select enter

Set root password? [Y/n] y

Set password and initialize

Password devops, enter y all the way.

[root@controller] # mysql-uroot-pdevops

Create a database

[root@controller] # mysql-uroot-pdevops

II. Installation of RabbitMQ service

[root@controller ~] # yum-y install erlang

[root@controller ~] # yum install-y rabbitmq-server

[root@controller ~] # systemctl enable rabbitmq-server.service

[root@controller ~] # systemctl start rabbitmq-server.service

[root@controller ~] # systemctl status rabbitmq-server.service

[root@controller ~] # systemctl list-unit-files | grep rabbitmq-server.service

[root@controller ~] # rabbitmqctl add_user openstack devops user name is: openstack password: devops

Creating user "openstack"...

[root@controller ~] # rabbitmqctl set_user_tags openstack administrator sets openstack as administrator

Setting tags for user "openstack" to [administrator]...

[root@controller ~] # rabbitmqctl set_permissions openstack "."

[root@controller ~] # rabbitmq-plugins list View supported plug-ins

[root@controller ~] # rabbitmq-plugins enable rabbitmq_management launch plug-in

Plugin configuration unchanged.
