保护企业私有云，构建 Openstack yum 源操作示例
对于企业的 Openstack 私有云，出于安全和某些因素的考虑，有些服务器无法访问公网，导致服务器无法更新某些 RPM 包，同时内部常有 Openstack 新特性开发需求、版本的维护与升级，因此非常有必要构建企业私有的 openstack yum 源。 构建 openstack yum 源有两个步骤：1.同步(下载)官方的源至企业 yum 服务器中；2. 重新创建 repo 并通过 nginx(apache)发布。
Overview
以 Redhat Openstack 官网安装手册为例，安装 Openstack 需要用到两类共计 8 个 repo，
1). Centos 源
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
2). openstack 源及相关依赖源(epel, foreman, puppet)：
epel.repo foreman.repo puppetlabs.repo rdo-release.repo
构建本地源步骤
1.yum源文件下载
(1).下载必要工具：
[root@yumserver ~]# yum -y install wget
[root@yumserver ~]# yum -y install createrepo
(2).下载yum源到本地：
[root@yumserver ~]# mkdir -p /wget-yum
[root@yumserver ~]# cd /wget-yum
下载Centos 源：
[root@yumserver wget-yum]# wget -S -c -r -np -L http://mirrors.sohu.com/centos/6.5/
下载foreman源：
[root@yumserver wget-yum]# wget -S -c -r -np -L http://yum.theforeman.org/plugins/1.5/el6/
[root@yumserver wget-yum]# wget -S -c -r -np -L http://yum.theforeman.org/releases/1.5/el6/
下载epel源：
[root@yumserver wget-yum]# wget -S -c -r -np -L http://mirrors.yun-idc.com/epel/6/
下载puppetlabs源：
[root@yumserver wget-yum]# wget -S -c -r -np -L https://yum.puppetlabs.com/el/6/
下载openstack源：
[root@yumserver wget-yum]# wget -S -c -r -np -L https://repos.fedorapeople.org/repos/openstack/openstack-havana/
[root@yumserver wget-yum]# wget -S -c -r -np -L https://repos.fedorapeople.org/repos/openstack/openstack-icehouse/
(3).删除不需要的软件包和文件：
[root@yumserver wget-yum]# find ./ -name index.html* | xarge rm -rf
[root@yumserver wget-yum]# find ./ -name fedora-20 | xarge rm -rf
[root@yumserver wget-yum]# find ./ -name fedora-19 | xarge rm -rf
[root@yumserver wget-yum]# find ./ -name i386 | xarge rm -rf
(4).调整目录结构：
[root@yumserver wget-yum]# mkdir foreman
[root@yumserver wget-yum]# mv yum.theforeman.org/plugins foreman/
[root@yumserver wget-yum]# mv yum.theforeman.org/releases foreman/
[root@yumserver wget-yum]# rm -rf yum.theforeman.org
[root@yumserver wget-yum]# mv mirrors.yun-idc.com/epel ./
[root@yumserver wget-yum]# rm -rf mirrors.yun-idc.com
[root@yumserver wget-yum]# mkdir puppetlabs
[root@yumserver wget-yum]# mv yum.puppetlabs.com/el /puppetlabs/
[root@yumserver wget-yum]# rm -rf yum.puppetlabs.com
[root@yumserver wget-yum]# mv repos.fedorapeople.org/repos/openstack ./
[root@yumserver wget-yum]# rm -rf repos.fedorapeople.org
[root@yumserver wget-yum]# ls
centos epel foreman openstack puppetlabs
2.nginx配置：
[root@yumserver wget-yum]# rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
[root@yumserver wget-yum]# yum -y install nginx
[root@yumserver wget-yum]# vi /etc/nginx/nginx.conf
<span style="color: rgb(69, 69, 69); font-family: Arial, sans-serif; font-size: 14px; line-height: 20px;">[root@yumserver wget-yum]# vi /etc/nginx/nginx.conf</span>
user nginx;
worker_processes 8;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 8192;
}
http {
autoindex on;
autoindex_exact_size off;
autoindex_localtime on;
charset utf-8,gbk;
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
keepalive_timeout 65;
include /etc/nginx/conf.d/*.conf;
}
[root@yumserver wget-yum]# vi /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name openstack-yum-server.cn;
location / {
#root html;
root /wget-yum;
autoindex on;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
} [root@yumserver wget-yum]# /etc/init.d/nginx restart
3. release.rpm制作：
(1).下载icehouse源码包：
[root@yumserver ~]# wget https://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-release-icehouse-4.src.rpm
(2).创建padraig用户和组：
[root@yumserver ~]# groupadd -g 2000 padraig
[root@yumserver ~]# useradd -u 2000 -g padraig -m padraig -d /home -s /bin/bash
(3).解压rpm，并修改各个 .repo 文件的 url：
[root@yumserver ~]# rpm -i rdo-release-icehouse-4.src.rpm
修改 .repo 文件，以 rdo-release.repo 为例
[openstack-havana] name=OpenStack Havana Repository baseurl=http://openstack-yum-server.cn/openstack/openstack-havana/epel-6/ enabled=1 skip_if_unavailable=0 gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RDO-Havana priority=98
(4).修改 .spec 文件内容：
[root@yumserver ~]# cd rpmbuild/
[root@yumserver rpmbuild]#
SOURCES SPECS
[root@yumserver ~]# cd SPECS
[root@yumserver SPECS]# vi rdo-release.spec
URL: https://github.com/redhat-openstack/rdo-release
Source0: rdo-release.repo
Source1: RPM-GPG-KEY-RDO-Icehouse
Source2: foreman.repo
Source3: RPM-GPG-KEY-foreman
Source4: puppetlabs.repo
Source5: RPM-GPG-KEY-puppetlabs
Source6: epel.repo
Source7: RPM-GPG-KEY-EPEL-6
%install
install -p -D -m 644 %{SOURCE0} %{buildroot}%{_sysconfdir}/yum.repos.d/rdo-release.repo
install -p -D -m 644 %{SOURCE2} %{buildroot}%{_sysconfdir}/yum.repos.d/foreman.repo
install -p -D -m 644 %{SOURCE4} %{buildroot}%{_sysconfdir}/yum.repos.d/puppetlabs.repo
install -p -D -m 644 %{SOURCE6} %{buildroot}%{_sysconfdir}/yum.repos.d/epel.repo
#GPG Keys
install -Dpm 644 %{SOURCE1} %{buildroot}%{_sysconfdir}/pki/rpm-gpg/RPM-GPG-KEY-RDO-Icehouse
install -Dpm 644 %{SOURCE3} %{buildroot}%{_sysconfdir}/pki/rpm-gpg/RPM-GPG-KEY-foreman
install -Dpm 644 %{SOURCE5} %{buildroot}%{_sysconfdir}/pki/rpm-gpg/RPM-GPG-KEY-puppetlabs
install -Dpm 644 %{SOURCE7} %{buildroot}%{_sysconfdir}/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
for repo in rdo-release foreman puppetlabs epel ; do
(5).修改SOURCES文件内容，并增加相应文件：
[root@yumserver SPECS]# cd ../SOURCES
[root@yumserver SOURCES]# ls
epel.repo foreman.repo puppetlabs.repo rdo-release.repo RPM-GPG-KEY-EPEL-6 RPM-GPG-KEY-foreman RPM-GPG-KEY-puppetlabs RPM-GPG-KEY-RDO-Icehouse
(6).重新打包rpm：
[root@yumserver SPECS]# yum -y install rpm-build
[root@yumserver SPECS]# pwd
/root/rpmbuild/SPECS
[root@yumserver SPECS]# rpmbuild -ba rdo-release.spec
4. 解决依赖关系，创建仓库：
[root@yumserver updates]# ls
repodata x86_64
[root@yumserver updates]# pwd
yum-repo/openstack/openstack-icehouse/updates
[root@yumserver updates]# createrepo x86_64
5. repo 更新 RPM 包：
createrepo x86_64 --update

编译后的rpm源码包示例：
new-rdo-release-havana-8.0.src.rpm
new-rdo-release-icehouse-4.0.src.rpm
troubleshooting:
yum repolist 出现
[root@controller yum.repos.d]# yum repolist
Loaded plugins: axelget, fastestmirror, security
Loading mirror speeds from cached hostfile

解决方案：
1)
每个 repo 配置新增 proxy=None
[openstack-havana-updates]
