部署环境
Linux：red-hat-enterprise-linux-7.1.shared
RDO：RHEL7OSP-6.0-2015-02-23.2-x86_64.iso
问题记录1
使用非注册redhat（版本：7.1）yum命令时被提示：
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
原因分析
使用redhat版本的yum源是需要收费的。
解决方案
选择使用Centos的yum源。
操作步骤
1、卸载原redhat 自带yum
2、寻找centos相关yum软件包进行rpm 安装，安装时要解决依赖问题，比较麻烦
3、修改repo文件，将地址指向国内镜像服务器

问题记录2
在问题1解决的基础上，使用yum update命令出错，系统提示：
错误：unbound-libs conflicts with redhat-release-server-7.1-1.el7.x86_64
错误：initscripts conflicts with redhat-release-server-7.1-1.el7.x86_64answer
且在使用packstack 脚本安装方式时，到达Installing Dependencies 这一步骤时也出现报错：
Error: initscripts conflicts with redhat-release-server-7.1-1.el7.x86_64
原因分析
系统提示非常明显，软件包有冲突
解决方案
卸载冲突软件包
操作步骤
rpm -e redhat-release-server-7.1-1.el7.x86_64 --nodeps
yum update

问题记录3
在yum update之后，系统提示yum命令无法使用。
One of the configured repositories failed (CentOS-7 - Contrib - mirrors.aliyun.com), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail.
原因分析
网上看了一些解决方案，如增加DNS配置、将repo文件中的mirrorlist改为baseurl，不适用。
在/etc/yum.repos.d/文件夹中，新增了很多repo文件，怀疑可能是因为repo文件中的地址重复导致。
CentOS-Base.repo CentOS-fasttrack.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-Media.repo local.repo
CentOS-Debuginfo.repo CentOS-Sources.repo redhat.repo
解决方案
将/etc/yum.repos.d/文件夹中，新增了很多repo文件移动到bak文件夹中。
操作步骤
mkdir ./bak
mv CentOS* ./bak
yum clean all
yum makecache

原因分析
mariadb-galera-server 在osp源中为1:5.5.40，与base源中的1:5.5.60发生版本冲突。
解决方案
将yum源中的mariadb相关软件包重新安装，降版本处理。
登陆mariadb官网后发现，repo文件能提供的版本为5.5.63，高于需求版本，因此在阿里云镜像站中寻找相关版本，通过RPM安装方式手动安装。
主要安装包有以下（怕有前后依赖所以都rpm执行操作了一遍）：
1 mariadb-libs-5.5.40-1.el7_0.x86_64.rpm
2 mariadb-5.5.40-1.el7_0.x86_64.rpm
3 mariadb-bench-5.5.40-1.el7_0.x86_64.rpm
4 mariadb-5.5.40-1.el7_0.src.rpm
5 mariadb-devel-5.5.40-1.el7_0.x86_64.rpm
6 mariadb-embedded-5.5.40-1.el7_0.x86_64.rpm
7 mariadb-embedded-devel-5.5.40-1.el7_0.x86_64.rpm
注意：如果有安装到mariadb-server-5.5.40-1.el7_0.x86_64这个包，要卸载掉。
操作步骤
yum remove mariadb*
rpm -qa | grep mariadb
#确认没有mariadb的包
yum install perl-DBI.x86_64 perl-DBD-MySQL.x86_64 perl-GD.x86_64 perl-Env.noarch perl-Test-Simple openssl-devel
#在安装相关软件包时需要注意依赖关系，如：perl-DBI.x86_64、perl-DBD-MySQL.x86_64 、perl-GD.x86_64、perl-Env.noarch、perl-Test-Simple、openssl-devel等。
rpm -ivh mariadb*
rpm -e mariadb-server-5.5.40-1.el7_0.x86_64

ERROR : Error appeared during Puppet run: 10.211.55.15_cinder.pp
Error: cinder type-create iscsi returned 1 instead of one of [0]
打开log日志
Error: cinder type-create iscsi returned 1 instead of one of [0]
Error: /Stage[main]/Main/Cinder::Type[iscsi]/Exec[cinder type-create iscsi]/returns: change from notrun to 0 failed: cinder type-create iscsi returned 1 instead of one of [0]
原因分析
从报错信息来看是在执行cinder type-create iscsi命令时出错，通过搜索，觉得是由于脚本执行过多次，可能存在多余的cinder type，因此尝试删除。
首先由于脚本未执行完成，无法获得/home目录下的keystonerc_admin文件，因此需要自建。
进入openstack执行环境后，发现cinder命令无法使用，出现报错：
ERROR: Unable to establish connection to http://controller:35357/
排查端口，发现端口都是listen状态，systemctl status openstack-cinder-api.service ，发现状态是failed，重启。
最终结论：非存在多余的cinder
解决方案
重启openstack-cinder-api服务。
网上其他参考文章的建议：如vgremove cindervolumes，cinder-type delete ID 不适用。
操作步骤
vim keystonerc_admin
export OS_USERNAME=admin
export OS_TENANT_NAME=admin
export OS_PASSWORD=[根据answer file 来]
export OS_AUTH_URL=http://$IP:5000/v2.0/
export OS_REGION_NAME=RegionOne
export PS1='[\u@\h \W(keystone_admin)]\$ '
systemctl status openstack-cinder-api.service
systemctl restart openstack-cinder-api.service
source keystoneerc_admin
cinder -type list
