OpenStack环境搭建

实验环境

CentOS-7-x86_64-Minimal-1708.iso

openstack_N.tar.gz

创建虚拟机

controller部署

computer网络配置

OpenStack环境准备

controller节点和cpmputer节点执行相同过程

关闭/禁用firewalld

[root@controller ~]# systemctl stop firewalld
[root@controller ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

关闭/禁用NetworkManager

[root@controller ~]# systemctl stop NetworkManager
[root@controller ~]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.

禁用SELINUX

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

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disable
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

修改hosts

[root@controller ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.80.10 controller controller.cac.com
192.168.80.20 computer computer.cac.com

创建本地yum源

[root@controller yum.repos.d]# cat openstack.repo 
[openstack]
name=openstack
enable=1
gpgcheck=0
baseurl=file:///openstack

OpenStack自动化部署

首先安装自动化软件openstack-packstack，利用openstack-packstack生成应答文件，修改应答文件，再依据应答文件进行安装

yum search centos

View Code

yum -y install centos-release-openstack-newton

View Code

安装完毕后，会在/etc/yum.repos.d/又生成几个repo文件，我们安装不需要联网，将新生成的repo移入bak

[root@controller yum.repos.d]# ls
bak  CentOS-Ceph-Jewel.repo  CentOS-OpenStack-newton.repo  CentOS-QEMU-EV.repo  openstack.repo
[root@controller yum.repos.d]# mv C* bak/
[root@controller yum.repos.d]# ls
bak  openstack.repo

安装openstack-packstack

yum -y install openstack-packstack

View Code

生成应答文件(只在controller节点执行)

[root@controller yum.repos.d]# packstack --gen-answer-file=openstack.txt
Packstack changed given value  to required value /root/.ssh/id_rsa.pub

View Code

修改应答文件

首先修改如下选项

CONFIG_DEFAULT_PASSWORD=111111

CONFIG_SWIFT_INSTALL=n

CONFIG_NAGIOS_INSTALL=n

CONFIG_COMPUTE_HOSTS=192.168.80.20

CONFIG_NETWORK_HOSTS=192.168.80.20

CONFIG_CINDER_VOLUMES_SIZE=1G

CONFIG_PROVISION_DEMO=n

CONFIG_LBAAS_INSTALL=y

CONFIG_NEUTRON_FWAAS=y

CONFIG_NEUTRON_VPNAAS=y

View Code

执行grep -vE "^#|^$" openstack.txt发现有很多密码设置，修改密码为111111。

sed -i -r 's/(.+_PW)=.+/\1=111111/' openstack.txt

View Code

依据应答文件进行安装

packstack --answer-file=openstack.txt

View Code

安装过程中报错

failure: repodata/repomd.xml from centos-ceph-jewel: [Errno 256] No more mirrors to try.
http://mirror.centos.org/centos/7/storage/x86_64/ceph-jewel/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirror.centos.org; Unknown error"

原因：再computer节点上/etc/yum.repos.d目录下有生产了新的repo文件，将repo移入bak目录，再次安装

安装过程大约20min

tail -f /var/log/messages可以查看安装日志

查看是否安装rabbitmq

rpm -qa | grep rabbitmq-server

View Code

查看rabbitmq状态

systemctl status rabbitmq-server

View Code

启用rabbitmq管理服务

rabbitmq-plugins list
rabbitmq-plugins enable rabbitmq_management

View Code

检查是否启动成功

netstat -antlp | grep 15672

View Code

安装完成
