Openstack搭建
环境准备
| 主机名称 | IP地址 | 最小资源配置 |
|---|---|---|
| openstack | 192.168.1.10 | 2CPU,8G内存 |
| nova01 | 192.168.1.11 | 2CPU,3G内存 |
| nova02 | 192.168.1.12 | 2CPU,3G内存 |
| repo | 192.168.1.250 | 2CPU,1G内存 |
1,修改ip
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
ONBOOT="yes"
NM_CONTROLLED="no"
TYPE="Ethernet"
BOOTPROTO="static"
IPADDR="192.168.1.10"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.254"
[root@localhost ~]# echo nameserver 192.168.1.254 >/etc/resolv.conf
[root@localhost ~]# ifdown eth0
[root@localhost ~]# ifup eth0
[root@localhost ~]# hostnamectl set-hostname openstack #修改主机名称2,功能服务的安装 上传 RHEL7-extras.iso、RHEL7OSP-10.iso 到功能服务器[repo]
时间源服务器
[root@repo ~]# yum install -y chrony
[root@repo ~]# vim /etc/chrony.conf
# 注释掉所有 server 开头的行，添加
server ntp.aliyun.com iburst
bindacqaddress 0.0.0.0
allow 0/0
local stratum 10
[root@repo ~]# systemctl enable chronyd
[root@repo ~]# systemctl restart chronyd
[root@repo ~]# ss -ltun # 查看 123 端口是否被监听成功3，网络yum源服务器
[root@repo ~]# yum install -y vsftpd
[root@repo ~]# systemctl enable --now vsftpd
[root@repo ~]# mkdir -p /var/ftp/{extras,openstack}
[root@repo ~]# cd /var/iso
[root@repo ~]# mount -t iso9660 -o ro,loop RHEL7-extras.iso /var/ftp/extras
[root@repo ~]# mount -t iso9660 -o ro,loop RHEL7OSP-10.iso /var/ftp/openstack
# 在openstack上验证
[root@openstack ~]# curl ftp://192.168.1.250/extras/
[root@openstack ~]# curl ftp://192.168.1.250/openstack/
注意 要是验证失败，两边关闭防火墙 selinux禁用 重启 再执行以上步骤4,openstack系统环境安装配置
以下操作，openstack，nova01 ,nova02都需要做
[root@openstack ~]# vim /etc/selinux/config
# 修改 SELINUX=disabled
[root@openstack ~]# yum -y remove firewalld-*
[root@openstack ~]# reboot
# 重启后验证
[root@openstack ~]# sestatus
SELinux status: disabled
[root@openstack ~]# rpm -qa |grep -i firewalld
[root@openstack ~]# 卸载 NetworkManager
[root@openstack ~]# systemctl stop NetworkManager
[root@openstack ~]# yum remove -y NetworkManager
[root@openstack ~]# systemctl enable --now network5,Yum安装源配置 openstack，nova01 ,nova02都需要做
确认软件包总数是 10670

repolist: 10,670时间服务器配置 openstack，nova01 ,nova02都需要做
[root@openstack ~]# vim /etc/chrony.conf
# 注释掉所有 server 开头的行，添加
server 192.168.1.250 iburst
[root@openstack ~]# systemctl restart chronyd
[root@openstack ~]# chronyc sources -v # 验证配置 ^* 代表成功主机名与DNS配置openstack，nova01 ,nova02都需要做
[root@openstack ~]# vim /etc/hosts
192.168.1.10 openstack
192.168.1.11 nova01
192.168.1.12 nova02
192.168.1.250 repo
# 删除所有 search 开头的行
[root@openstack ~]# sed '/^search /d' -i /etc/resolv.conf6,nova虚拟环境安装
nova01 ,nova02安装
[root@nova01 ~]# yum install -y qemu-kvm libvirt-daemon libvirt-daemon-driver-qemu libvirt-client python-setuptools
[root@nova01 ~]# systemctl enable --now libvirtd
[root@nova01 ~]# virsh version # 验证 packstack工具安装
只需要在 openstack 上安装即可
[root@openstack ~]# yum install -y python-setuptools openstack-packstackopenstack安装
使用应答文件安装，只需要在 openstack 上安装即可
# 创建应答文件
[root@openstack ~]# packstack --gen-answer-file=answer.ini
# 修改应答文件
42: CONFIG_SWIFT_INSTALL=n //存储对象组件
45: CONFIG_CEILOMETER_INSTALL=n //计费模块
49: CONFIG_AODH_INSTALL=n //计费模块
53: CONFIG_GNOCCHI_INSTALL=n //计费模块

1179: CONFIG_PROVISION_DEMO=n //演示模块创建完应答文件后做快照 做快照 做快照 做快照 做快照 (openstack nova01 nova02 )都做快照
安装过程大约 10 ~ 30 分钟不等
[root@openstack ~]# packstack --answer-file=answer.ini7，web页面登录
修改 apache 配置
[root@openstack ~]# vim /etc/httpd/conf.d/15-horizon_vhost.conf
# 在配置文件倒数第三行添加
WSGIApplicationGroup %{GLOBAL}
[root@openstack ~]# systemctl reload httpd账号：admin
密码: a
8,命令行登录openstack
[root@openstack ~]# openstack user list
