centos7 packstack安装openstack rocky
实验环境
-
控制节点：192.168.26.71 4c8g Centos7 200G硬盘
-
计算节点：192.168.26.72 4c8g Centos7 200G硬盘
初始化（所有节点）
添加hosts
vi /etc/hosts
#添加
192.168.26.71 vms71
192.168.26.72 vms72
关闭防火墙和SELinux
firewall-cmd --set-default-zone=trusted
sed -i '/SELINUX=/cSELINUX=disabled' /etc/sysconfig/selinux
setenforce 0
禁用NetworkManager
systemctl stop NetworkManager
systemctl disable NetworkManager
添加阿里源
yum install wget
wget https://xiebo.pro/tools/openstack/ali.repo -P /etc/yum.repos.d/
yum clean all
手动上传安装缺少的依赖
https://xiebo-pro/tools/openstack/python2-pyngus-2.3.0-1.el7.noarch.rpm
https://xiebo-pro/tools/openstack/python2-qpid-proton-0.31.0-3.el7.x86_64.rpm
https://xiebo-pro/tools/openstack/qpid-proton-c-0.31.0-3.el7.x86_64.rpm
将以上三个包上传，进入到上传目录
yum install * -y
降低leatherman版本
yum remove leatherman-1.10.0-1.el7.x86_64
yum install leatherman-1.3.0-9.el7.x86_64
安装packstack及openstack(控制节点操作)
安装packstack
yum install openstack-packstack
#openstack工具包utils(可选)
yum install openstack-utils
生成模板配置文件
packstack --gen-answer-file=aa.txt
修改配置
sed -i '/^CONFIG_PROVISION_DEMO=/cCONFIG_PROVISION_DEMO=n' aa.txt
#网络设置
sed -i '/^CONFIG_NEUTRON_ML2_TYPE_DRIVERS=/cCONFIG_NEUTRON_ML2_TYPE_DRIVERS=flat, vxlan' aa.txt
sed -i '/^CONFIG_NEUTRON_ML2_FLAT_NETWORKS=/cCONFIG_NEUTRON_ML2_FLAT_NETWORKS=datacentre' aa.txt
sed -i '/^CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=/cCONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=datacentre:br-ex' aa.txt
#管理员密码
sed -i.bak -r 's/(.+_PW)=[0-9a-z]+/\1=password/g' aa.txt
安装openstack
packstack --answer-file=aa.txt
安装完成打开dashboard
http://192.168.26.71/dashboard
账号admin 密码为配置文件中设置，如未设置可查看/root/keystonerc_admin获得初始密码
[root@vms71 ~]# cat keystonerc_admin
unset OS_SERVICE_TOKEN
export OS_USERNAME=admin
export OS_PASSWORD='password'
export OS_REGION_NAME=RegionOne
export OS_AUTH_URL=http://192.168.26.71:5000/v3

export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3
创建桥接网桥
创建ifcfg-br-ex，修改ifcfg-ens32
[root@vms71 ~]# cat /etc/sysconfig/network-scripts/ifcfg-br-ex
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=none
IPADDR=192.168.26.71
NETMASK=255.255.255.0
GATEWAY=192.168.26.2
DNS1=192.168.26.2

[root@vms71 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens32
DEVICE=ens32
DEVICETYPE=ovs
TYPE=OVSPort
ONBOOT=yes
BOOTPROTO=none
OVS_BRIDGE=br-ex
[root@vms71 ~]# systemctl restart network
