（一）安装前的准备

1、初始化

[root@localhost ~]# hostnamectl set-hostname openstack
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# 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.
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPADDR=10.0.15.200
NETMASK=255.255.255.0
DNS1=114.114.114.114
GATEWAY=10.0.15.2
NAME=eth0
UUID=9626c5da-56c5-4750-8ee8-53513b8d4833
DEVICE=eth0
ONBOOT=yes
​
[root@localhost ~]# vi /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=disabled 
# 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 
​
​
[root@openstack ~]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.15.200     openstack
​
[root@localhost ~]# reboot

2、修改yum仓库

[root@openstack ~]# rm -rfv /etc/yum.repos.d/*
removed ‘/etc/yum.repos.d/CentOS-Base.repo’
removed ‘/etc/yum.repos.d/CentOS-CR.repo’
removed ‘/etc/yum.repos.d/CentOS-Debuginfo.repo’
removed ‘/etc/yum.repos.d/CentOS-Media.repo’
removed ‘/etc/yum.repos.d/CentOS-Sources.repo’
removed ‘/etc/yum.repos.d/CentOS-Vault.repo’
removed ‘/etc/yum.repos.d/CentOS-fasttrack.repo’
[root@openstack ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  2523  100  2523    0     0  23227      0 --:--:-- --:--:-- --:--:-- 23361
[root@openstack ~]# sed -i /aliyuncs/d /etc/yum.repos.d/*.repo
[root@openstack ~]# yum clean all;yum repolist all

3、linux必要软件包安装

[root@openstack ~]# yum install vim bash-completion tree net-tools wget lrzsz zip unzip -y

（二）安装过程

1、安装openstack软件库

[root@openstack ~]# yum install centos-release-openstack-stein  -y

2、安装Packstack工具

[root@openstack ~]# yum install  openstack-packstack -y

3、一键部署openstack（需要等待一段时间）

[root@openstack ~]# packstack --allinone

（三）安装后的调整

1、生成虚拟网桥

[root@openstack ~]# cd /etc/sysconfig/network-scripts/
[root@openstack network-scripts]# cp ifcfg-eth0 ifcfg-br-ex
[root@openstack network-scripts]# vi ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSPort
OVS_BRIDGE=br-ex
[root@openstack network-scripts]# vi ifcfg-br-ex
IPADDR=10.0.15.200
NETMASK=255.255.255.0
GATEWAY=10.0.15.2
DNS1=114.114.114.114
OTPROTO=none
DEFROUTE=yes
NAME=br-ex
DEVICE=br-ex
ONBOOT=yes
PEERDNS=no
NM_CONTROLLED=no
[root@openstack network-scripts]# ovs-vsctl add-port br-ex eth0    （命令执行后远程连接会断开，在虚拟机里执行systemctl restart network）

2、查看登陆密码

[root@openstack ~]# cat keystonerc_admin
unset OS_SERVICE_TOKEN
    export OS_USERNAME=admin
    export OS_PASSWORD='09012425534d4139'
    export OS_REGION_NAME=RegionOne
    export OS_AUTH_URL=http://10.0.15.200:5000/v3
    export PS1='[\u@\h \W(keystone_admin)]\$ '
    
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3

3、登陆访问

 

4、登陆成功

 

（四）安装备注

1、可能碰到的问题及解决方法

使用了epel源，将leatherman更新。

不使用epel源，将不会碰到这个问题 leatherman 版本过高

[root@openstack ~]# yum downgrade leatherman -y

卸载后执行（file为root家目录下的一个以时间和日期命名的.txt文化）

[root@openstack ~]# packstack --answer-file=

 

未安装python2-qpid-proton

[root@openstack ~]# yum install python2-qpid-proton -y

2、安装完成后家目录下生成文件的作用

###安装完成后家目录下生成了以下三个文件

packstack-answers-20220307-042836.txt ###allinone自动应答文件,里面包含了openstack创建时需要的配置信息，例如admin用户的登陆密码，各组件的数据库密码，物理网络名称等等

keystonerc_admin ###admin用户的环境变量，管理openstack前必须使用，使用方法 . keystonerc_admin 或者 source keystonerc_admin

keystonerc_demo ###demo用户的环境变量
