這篇文章主要介紹了CentOS7.2部署OpenStack（一）—環(huán)境準(zhǔn)備，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

本篇文章介紹CentOS7.2部署OpenStack，具體如下：

1、系統(tǒng)環(huán)境

# uname -r

3.10.0-327.el7.x86_64

# cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

2、服務(wù)器部署

3、基礎(chǔ)環(huán)境準(zhǔn)備

3.1、配置hosts

# cat /etc/hosts

192.168.56.108 controller

192.168.56.109 compute

3.2、配置時間同步

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

[root@controller ~]# vim /etc/ntp.conf

15 restrict -6 ::1

16 restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

27 restrict 0.centos.pool.ntp.org nomodify notrap noquery

28 restrict 1.centos.pool.ntp.org nomodify notrap noquery

29 restrict 2.centos.pool.ntp.org nomodify notrap noquery

30 restrict 3.centos.pool.ntp.org nomodify notrap noquery

31 server 127.127.1.0

32 fudge 127.127.1.0 stratum 10

[root@controller ~]# systemctl enable ntpd

[root@controller ~]# systemctl start ntpd

在控制節(jié)點(diǎn)和計算節(jié)點(diǎn)配置定時任務(wù)

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

3.3、關(guān)閉防火墻

# systemctl stop firewalld

3.4、關(guān)閉selinux

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

3.5、安裝基礎(chǔ)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 = innodb

innodb_file_per_table

collation-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 openstack

Creating 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

在瀏覽器中輸入http://192.168.56.108:15672，默認(rèn)賬戶和密碼為guest

登錄后將前面創(chuàng)建的openstack用戶加入到admin中，結(jié)果如下圖：
