使用PackStack安装OpenStack 单节点

环境准备

• 关闭相关服务

所有节点填写网络映射

echo "192.168.64.10 controller" >> /etc/hosts

所有节点永久关闭 selinux，永久关闭 firewalld，永久关闭 NetworkManager

systemctl stop firewalld; systemctl disable firewalld
systemctl stop NetworkManager; systemctl disable NetworkManager
sed -i 's#SELINUX=.*#SELINUX=disabled#g' /etc/selinux/config
reboot

• 配置yum

清空yum源

mv /etc/yum.repos.d/* /tmp/

在controller节点挂载本地源

[root@controller ~]$ mkdir -p /opt/{centos,extras,openstack}

[root@controller ~]$ mount -o loop /root/centos7-1804.iso /mnt/
[root@controller ~]$ cp -rvf /mnt/* /opt/centos/
[root@controller ~]$ umount /mnt/

[root@controller ~]$ mount -o loop /root/RHEL7-extras.iso /mnt/
[root@controller ~]$ cp -rvf /mnt/* /opt/extras/
[root@controller ~]$ umount /mnt/

[root@controller ~]$ mount -o loop /root/RHEL7OSP-10.iso /mnt/
[root@controller ~]$ cp -rvf /mnt/* /opt/openstack/
[root@controller ~]$ umount /mnt/

在controller节点编写本地源

[root@controller ~]$ vi /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=file:///opt/centos/
gpgcheck=0
enabled=1

[extras]
name=extras
baseurl=file:///opt/extras/
gpgcheck=0
enabled=1

[openstack]
name=openstack-10
baseurl=file:///opt/openstack/rhel-7-server-openstack-10-rpms/
gpgcheck=0
enabled=1

[openstack-devtool]
name=openstack-10-devtools
baseurl=file:///opt/openstack/rhel-7-server-openstack-10-devtools-rpms/
gpgcheck=0
enabled=1

• 需要安装的依赖包

qemu-kvm -> 硬件仿真 -> compute节点

libvirt-daemon -> 后台管理进程，管理硬件仿真 -> compute节点

libvirt-daemon-driver-qemu -> 驱动程序 -> compute节点

libvirt-client -> 后台管理的接口 -> compute节点

python-setuptools -> Python -> controller节点

节点安装依赖

yum -y install qemu-kvm libvirt-client libvirt-daemon libvirt-daemon-driver-qemu python-setuptool

• 检查基础环境

是否禁用 firewalld 和 NetworkManager

是否为静态 IP

主机之间是否能 ping 通

依赖包是否是10670

依赖是否安装

systemctl start libvirtd

NTP是否可用，时间是否同步

检查 /etc/resolv.conf 不能有search开头的行

安装 PackStack

• 安装OpenStack需要使用的 PackStack

在 controller节点 安装

#安装PackStack [root@controller ~]$ yum -y install openstack-packstack #使用PackStack创建应答文件 [root@controller ~]$ packstack --gen-answer-file=answer.ini

• 修改应答文件

sed -i "s#^CONFIG_SWIFT_INSTALL=.*#CONFIG_SWIFT_INSTALL=n#g" answer.ini
sed -i "s#^CON:FIG_CEILOMETER_INSTALL=.*#CONFIG_CEILOMETER_INSTALL=n#g" answer.ini
sed -i "s#^CONFIG_AODH_INSTALL=.*#CONFIG_AODH_INSTALL=n#g" answer.ini
sed -i "s#^CONFIG_GNOCCHI_INSTALL=.*#CONFIG_GNOCCHI_INSTALL=n#g" answer.ini
sed -i "s#^CONFIG_NTP_SERVERS=.*#CONFIG_NTP_SERVERS=time1.aliyun.com#g" answer.ini
sed -i "s#^CONFIG_COMPUTE_HOSTS=.*#CONFIG_COMPUTE_HOSTS=192.168.105.10#g" answer.ini
sed -i "s#^CONFIG_NETWORK_HOSTS=.*#CONFIG_NETWORK_HOSTS=192.168.105.10#g" answer.ini
sed -i "s#^CONFIG_KEYSTONE_ADMIN_PW=.*#CONFIG_KEYSTONE_ADMIN_PW=123456#g" answer.ini
sed -i "s#^CONFIG_NEUTRON_ML2_TYPE_DRIVERS=.*#CONFIG_NEUTRON_ML2_TYPE_DRIVERS=flat,vxlan#g" answer.ini
sed -i "s#^CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=.*#CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-ex#g" answer.ini
sed -i "s#^CONFIG_NEUTRON_OVS_BRIDGE_IFACES=.*#CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:ens33#g" answer.ini
sed -i "s#^CONFIG_PROVISION_DEMO=.*#CONFIG_PROVISION_DEMO=n#g" answer.ini

• 安装

[root@controller ~]$ packstack --answer-file=answer.ini

• 验证安装是否成功

配置Dashboard

[root@controller ~]$ vi /etc/httpd/conf.d/15-horizon_vhost.conf
#在 WSGIProcessGroup apache 下面 插入一行
WSGIApplicationGroup %{GLOBAL}

[root@controller ~]$ systemctl reload httpd
