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

#p#

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

 
 
   
  
  [root@yumserver wget-yum]# vi /etc/nginx/nginx.conf   
  
  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

#p#

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

http://openstack-yum-server/ceph/el6/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 403 Forbidden"
Trying other mirror.
http://openstack-yum-server/ceph/el6/noarch/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 403 Forbidden"
Trying other mirror.
.....

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

.....
_proxy_=None
2)

关闭防火墙， service iptables stop
