很多新手在入门 OpenStack 时往往会被复杂的部署步骤所困扰，如何快速拥有一个 openstack 实验环境呢，我选择 packstack，虽然是上古年间的工具，但是不得不说，真香~~~

1、实验环境

主机名 硬件，系统 网卡 IP
controller1 16g 500g，centos-2003 enp7s0 192.168.100.11
controller1 16g 500g，centos-2003 enp8s0 10.110.45.246
compute1 16g 3t，centos-2003 enp8s0 192.168.100.12
compute1 16g 3t，centos-2003 enp9s0 10.110.45.247
compute2 16g 3t，centos-2003 enp7s0 192.168.100.13
compute2 16g 3t，centos-2003 enp8s0 10.110.45.248

注意：第一块网卡为管理地址，第二块网卡为外网地址，本次实验使用100 网段为管理 ip，45 网段为公网（假装）ip，用作访问外网

2、配置 yum 源。（在所有节点）

由于前期已经在校园网上配置了完整的yum源，故直接拿来使用。
将ftp://10.110.45.221/bendi.repo下载到本地，并上传至所有节点的/etc/yum.repos.d目录。

  1. [root@compute2 ~]# scp root@10.110.45.221:/opt/bendi.repo /etc/yum.repos.d/
  2. 注：如果不知道密码，可以使用其他方法复制。
  3. [root@compute2 ~]# cd /etc/yum.repos.d
  4. [root@compute2 ~]# mkdir bak
  5. [root@compute2 ~]# mv C* bak
  6. [root@compute2 ~]# yum clean all
  7. [root@compute2 ~]#yum repolist

在控制节点上执行

  1. hostnamectl set-hostname controller1
  2. vi /etc/hosts
  3. 写入
  5. 192.168.100.11 controller1
  6. 192.168.100.12 compute1
  7. 192.168.100.13 compute2

在计算节点1上执行

  1. hostnamectl set-hostname compute1
  2. vi /etc/hosts
  3. 写入
  5. 192.168.100.11 controller1
  6. 192.168.100.12 compute1
  7. 192.168.100.13 compute2

在计算节点2上执行

  1. hostnamectl set-hostname compute2
  2. vi /etc/hosts
  3. 写入
  5. 192.168.100.11 controller1
  6. 192.168.100.12 compute1
  7. 192.168.100.13 compute2

3、做预处理在所有节点上

  1. echo 'net.ipv4.ip_forward=1 ' >>/etc/sysctl.conf 
  2. echo 'net.ipv4.tcp_tw_recycle=1 ' >>/etc/sysctl.conf
  3. echo 'net.ipv4.tcp_tw_reuse=1 ' >>/etc/sysctl.conf 
  4. sysctl -p
  5. chmod +x /etc/rc.d/rc.local
  6. yum install -y mlocate lrzsz tree vim nc nmap wget bash-completion bash-completion-extras cowsay sl htop iotop iftop lsof net-tools sysstat unzip bc psmisc ntpdate wc telnet-server bind-utils sshpass
  7. systemctl stop firewalld
  8. systemctl disable firewalld
  9. setenforce 0
  10. sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config
  11. systemctl stop NetworkManager
  12. systemctl disable NetworkManager
  13. yum clean all       
  14. yum makecache
  15. ntpdate ntp1.aliyun.com
  16. echo '*/30 * * * *  /sbin/ntpdate ntp1.aliyun.com >/dev/null 2>&1' >>/var/spool/cron/root

4、安装 packstack 并配置应答文件（从本步开始，只在 packstack（控制节点） 做配置）

  1. yum install centos-release-openstack-train -y 
  2. #将新增加的yum源文件移到bak目录，因为我们的本地源里面有该要的rpm。
  3. cd /etc/yum.repos.d
  4. mv C* bak
  7. yum install openstack-packstack -y
  8. #不执行此步骤会故障报错
  9. #facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory
  11. #leatherman rpm包版本问题
  12. yum list | grep leatherman
  13. #leatherman.x86_64                        1.10.0-1.el7                  @epel    
  14. #leatherman-devel.x86_64                  1.10.0-1.el7                  epel 
  16. #而facter需要1.3.0
  17.  facter -p
  18. #facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory
  20. #回退leatherman版本
  21. yum downgrade leatherman -y 
  23. #生成应答文件
  24.  packstack --gen-answer-file=openstack.txt
  25.  #用vim编辑 openstack.txt具体修改的内容在下一个代码框。
  26.   vim openstack.txt
  28. #设置所有密码为123456
  29. sed -i -r 's/(.+_PW)=.+/\1=123456/' openstack.txt 
  30. #备份应答文件
  31. egrep -v "^#|^$" openstack.txt >openstack.txt.bak1 
  33.  #使用openstack.txt应答文件进行系统自动部署。
  34. packstack --answer-file=openstack.txt 
  37.  此时可以喝杯茶，或者吃个饭，完事就可以看到安装完成的 openstack 了
  38. 完成后即可在浏览器打开http://192.168.100.11 访问 dashboard
  1.  vim openstack.txt
  2. 41 CONFIG_SWIFT_INSTALL=n  #y-n SWIFT是OpenStack的对象存储组件，默认是Y，在生产环境中一般是不装，所以改n
  3. 50 CONFIG_AODH_INSTALL=n   #y-n 不安装该服务
  4. 97 CONFIG_COMPUTE_HOSTS=192.168.100.12,192.168.100.13  #计算节点ip地址，IP地址之间用英文逗号隔开。
  5. 795 CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vxlan,flat
  6. 801 CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vxlan
  7. 808 CONFIG_NEUTRON_ML2_MECHANISM_DRIVERS=openvswitch
  8. 813 CONFIG_NEUTRON_ML2_FLAT_NETWORKS=enp7s0      #flat网络这边要设置物理网卡名字
  9. 840 CONFIG_NEUTRON_L2_AGENT=openvswitch            #L2网络的代理模式,也可选择linuxbridge
  10. 858 CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=enp7s0:br-ex    #这边要设置物理网卡的名字
  11. 869 CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:enp8s0         #这边br-ex:eth0是网络节点的nat网卡，到时候安装完毕之后IP地址会漂到这个上
  12. 1181 CONFIG_PROVISION_DEMO=n        #DEMO是OpenStack联网下载一个测试镜像，这边没联网。说以改成n

注意：以下仅作为参考。不是必须要做的。

packstack 部署禁止了 openstack 的 dashbrard 界面对域的支持，需要可打开

  1. vim /etc/openstack-dashboard/local_settings
  2. 79 OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
  3. 85 OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = 'Default'
  4. 461 TIME_ZONE = "Asia/Shanghai" 
  6. systemctl restart httpd.service memcached.service

查看用户密码：

  1. #使用admin用户的变量文件
  2. [root@controller1 ~]# . keystonerc_admin
  3. [root@controller1 ~]# cat keystonerc_admin 
  4. export OS_USERNAME=admin
  5. export OS_PASSWORD='123456'
  6. export OS_REGION_NAME=RegionOne
  7. export OS_AUTH_URL=http://192.168.100.11:5000/v3
  8. export OS_PROJECT_NAME=admin
  9. export OS_USER_DOMAIN_NAME=Default
  10. export OS_PROJECT_DOMAIN_NAME=Default
  11. export OS_IDENTITY_API_VERSION=3
  14. [root@controller1 ~(keystone_admin)]# openstack network agent list

  6.  41 CONFIG_SWIFT_INSTALL=n      ●第41行SWIFT是OpenStack的对象存储组件，默认是Y，在生产环境中一般是不装，所以该n
  7.  50 CONFIG_AODH_INSTALL=n      ●第50行，默认是Y 需要改n
  8.  94 CONFIG_CONTROLLER_HOST=192.168.100.10    第94行CONTROLLER是OpenStack的控制节点，在控制节点上配置的，不需要更改IP地址。
  9.  97 CONFIG_COMPUTE_HOSTS=192.168.100.11    ●第97行需要更改计算节点的IP地址

  11.  557 CONFIG_CINDER_VOLUMES_SIZE=1G     ●第557行 系统在创建CINDER组件的的时候回创建一个20G卷，因为我们虚拟机空间有限所以把空间改下点1G
  12.  778 CONFIG_NEUTRON_METADATA_PW=29948657b3aa409c    ●第778行，这样的29948657b3aa409c是密码

  18.  873 CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth1    ●第873行，这边br-ex:eth1是网络节点的nat网卡
  19.  1185 CONFIG_PROVISION_DEMO=n    ●第1185行 是OpenStack联网下载一个测试镜像，这边没联网。说以改成n

7、配置网络

创建 br-ex 网桥配置

创建并编辑 / etc/sysconfig/network-scripts/ifcfg-br-ex

DEVICE=br-ex

ONBOOT=yes

DEVICETYPE=ovs

TYPE=OVSBridge

BOOTPROTO=static

IPADDR=192.168.211.60

NETMASK=255.255.255.0

GATEWAY=192.168.211.1

将 ens33 网卡桥接到 br-ex 上去

修改 / etc/sysconfig/network-scripts/ifcfg-ens33

DEVICE=ens33

ONBOOT=yes

DEVICETYPE=ovs

TYPE=OVSPort

BOOTPROTO=yes

OVS_BRIDGE=br-ex

桥接完成后查看网卡信息，会发现 ens33 已经没有了 ip 地址，ip 转移到了 br-ex 网桥上

因为 packstack 测试镜像 cirros 都已经下好了 现在就可以愉快的启动实例了

曾经被 openstack 的网络搞的头皮发麻，这里发一下简单的流量走向，请大佬不喜勿喷，如有错误请大佬指点
