如何一步步使用国内yum源一键安装openstack-ocata版本基于centos7

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.
#

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

不要慌，检查你的文件夹下的yum 源，全部移除到备份文件夹
yum makecache 
重新开始执行

　　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。
