+# 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_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
+```
+
+
+验证登录 OpenStack dashboard
