本篇文章介紹CentOS7.2部署OpenStack，具體如下：

1、系統環境

# uname -r

3.10.0-327.el7.x86_64

# cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

2、服務器部署

3、基礎環境準備

3.1、配置hosts

# cat /etc/hosts192.168.56.108 controller192.168.56.109 compute

3.2、配置時間同步

[root@controller ~]# yum install -y ntp[root@controller ~]# vim /etc/ntp.conf15 restrict -6 ::116 restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap27 restrict 0.centos.pool.ntp.org nomodify notrap noquery28 restrict 1.centos.pool.ntp.org nomodify notrap noquery29 restrict 2.centos.pool.ntp.org nomodify notrap noquery30 restrict 3.centos.pool.ntp.org nomodify notrap noquery31 server 127.127.1.032 fudge 127.127.1.0 stratum 10[root@controller ~]# systemctl enable ntpd[root@controller ~]# systemctl start ntpd

在控制節點和計算節點配置定時任務

[root@compute ~]# crontab -l */5 * * * * /usr/sbin/ntpdate 192.168.56.108 >/dev/null 2>&1

3.3、關閉防火墻

# systemctl stop firewalld

3.4、關閉selinux

# SELINUX=disabled /etc/selinux/config //需要重啟

3.5、安裝基礎包

[root@controller ~]# yum install -yhttp://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-7.noarch.rpm[root@controller ~]# yum install -y centos-release-openstack-liberty[root@controller ~]# yum install -y python-openstackclient

3.6、安裝mysql

[root@controller ~]# yum install -y mariadb mariadb-server MySQL-python[root@controller ~]# vim /etc/my.cnf

在mysqld模塊添加如下幾行：

default-storage-engine = innodbinnodb_file_per_tablecollation-server = utf8_general_ci init-connect = 'SET NAMES utf8'character-set-server = utf8[root@controller ~]# systemctl enable mariadb.service[root@controller ~]# systemctl start mariadb.service[root@controller ~]# mysql_secure_installation

3.7、安裝rabbitmq

[root@controller ~]# yum install -y rabbitmq-server[root@controller ~]# systemctl enable rabbitmq-server.service[root@controller ~]# systemctl start rabbitmq-server.service[root@controller ~]# rabbitmqctl add_user openstack openstackCreating user "openstack" ......done.[root@controller ~]# rabbitmqctl set_permissions openstack '.*' '.*' '.*'Setting permissions for user "openstack" in vhost "/"......done.[root@controller ~]# rabbitmqctl set_user_tags openstack administrator[root@controller ~]# rabbitmq-plugins enable rabbitmq_management[root@controller ~]# systemctl restart rabbitmq-server.service
