内容图文
写在前面的话，在网上看了一个国外的一键安装视频，我也照着做，结果出现很多错误，现在把坑解决了，照着做肯定能安装成功的
环境
virtualhost 下的centos7
配置
双网卡 一个10网段，nat通信用 一个192网段 和宿主机通信使用
2c 这个测试部署的话，不是强要求，我部署后CPU也就占20%
5.4G内存 我的宿主机也就8G内存 配到这个数据已经很卡了 再次PS
安装完成要占用约5G左右的内存
部署
由于我的是nat 网络，所以先配置双网卡，否则部署后，不能正常访问openstack的管理网页，因为需要修改到这个参数，这个到后面再说
双网卡配置略过，自己在网上查吧很多的。实在找不到就留言
正式开始
1-设置yum源01_setyum.sh（非常重要，虽然出了openstack 专用的yum源，但那不是咱们能用的），我做成了脚本样子的，直接拷贝拿去用，镜像源用的是清华源，因为阿里源有的包跳转到404的链接还在上面，后面一键安装的时候就会坑哭你，亲测。。都是泪。脚本正文如下
#创建备份路径 mkdir -p /etc/yum.repos.d/bak_tmp/ #移走当前的所有源，为什么？因为一键安装会乱跳，跳到不能用的就报错，然后你就安装失败 mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak_tmp/ #创建yum 文件 touch /etc/yum.repos.d/centos-tuna.repo #导入镜像内容到yum文件中 cat >>/etc/yum.repos.d/centos-tuna.repo << EOF #CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-\$releasever - Base baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/\$releasever/os/\$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=\$releasever&arch=\$basearch&repo=os gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-\$releasever - Updates baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/\$releasever/updates/\$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=\$releasever&arch=\$basearch&repo=updates gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [centosplus] name=CentOS-\$releasever - Plus baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/\$releasever/centosplus/\$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=\$releasever&arch=\$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 [cloud] name=CentOS-\$releasever - Cloud baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/\$releasever/cloud/\$basearch/openstack-ocata/ enabled=1 gpgcheck=0 [paas] name=CentOS-\$releasever - paas baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/\$releasever/paas/\$basearch/openshift-origin13/ enabled=1 gpgcheck=0 [kvm] name=CentOS-\$releasever - kvm baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/\$releasever/virt/\$basearch/kvm-common/ enabled=1 gpgcheck=0 EOF #清除yum缓存 yum clean all #重新做yum 缓存 yum makecache
2-配置环境 02_setenv.sh
cat >/etc/environment <<EOF LANG=en_US.utf-8 LC_ALL=en_US.utf-8 EOF systemctl disable firewalld systemctl stop firewalld systemctl disable NetworkManager systemctl stop NetworkManager systemctl enable network systemctl restart network
3-安装一键部署包 03_set_openstack-packstack.sh
yum -y update yum install -y openstack-packstack #报错无法安装openstack-selinux 没有相关依赖包，通过增加paas 镜像源解决 yum install -y openstack-selinux yum -y install wget #--提示缺少libLibev.so.4()(64bit) wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo yum -y install libev
#有可能yum源混乱了，所以重新执行yibian mkdir -p /etc/yum.repos.d/bak_tmp_1 mv /etc/yum.repos.d/*.repo /etc/yum.repo.d/bak_tmp_1/ mv /etc/yum.repos.d/bak_tmp_1/centos-tuna.repo /etc/yum.repos.d/ yum clean all
yum makecache
#解决python-werkzeug 不在cloud源，在virt里面,所以找不到此包 wget -O /root/python-werkzeug-0.9.1-1.el7.noarch.rpm https://mirrors.tuna.tsinghua.edu.cn/centos/7/virt/x86_64/ovirt-4.3/common/python-werkzeug-0.9.1-1.el7.noarch.rpm rpm -ivh /root/python-werkzeug-0.9.1-1.el7.noarch.rpm
执行到这里才完成一点点，为了保险。重新进入到yum文件夹
cd /etc/yum.repos.d/ ll #确认当前只有一个centos-tuna.repo
确认完成执行最后一步安装操作，也就是出错最多的操作
#-d 表示debug 日志级别 packstack --allinone -d
安装成功的样例如下
比较长，就不展开了

部署成功后验证登陆，ip 为你自己虚拟机的ip，主要看
more /etc/httpd/15-hrion*.conf #记不清全拼了，找到这个文件 增加一个serveralias 192.168.x。x #宿主机和虚拟机能正常通信的IP #重启 systemctl restart httpd
千辛万苦就是要看到这么一个图。爬坑也是花时间的，现在总结在这里。祝你们测试部署成功
登陆的账号密码在
--密码文件在root用户目录下
cat /root/keystonerc_admin
复制OS_USERNAME=admin
OS_PASSWORD=XXXX
结束语
这次的部署获益良多，要感谢阿里云yum源的一个功能，就是在页面可以支持搜索包，这样我就知道这个包在哪个文件夹下，也是感谢清华yum源的给力，通过在阿里yum搜索到的包，去清华yum源找到对应的页面 ，一步步配置到第一步设置的yum中。才能正常的安装这个一键安装包。否则在vpn的龟速下是很难正常完成一键部署的安装，这个一键部署的openstack 主要还是用来体会一下openstack是一个怎么样使用的。自己装一次，比看10次文档还印象深刻。
