美河学习openstack基础篇构建yum源

1、构建 OpenStack yum 源对于企业的 Openstack 私有云，出于安全和某些公网，导致服务器无法更新某些 RPM 包，同时的考虑，有些服务器无法常有 Openstack 新特性开发需求、版本的与升级，因此非常有必要构建企业私有的 openstackyum 源。 构建openstack yum 源有两个步骤：的源至企业 yum 服务器中；1、同步(2、重新创建)repo 并通过 nginx(apache)发布。1、概述以 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.

2、repoCentOS-Debuginfo.repoCentOS-Media.repoCentOS-Vault.rep o2). openstack 源及相关依赖源(epel, foreman, puppet)：epel.repo foreman.repopuppetlabs.repordo-release.repo2、构建本地源步骤 1）yum 源文件必要工具：(1).rootyumserver # yum -y install wgetrootyumserver # yum -y install createrepoyum 源到本地：(2).rootyumserver # mkdir -p

3、/wget-yumrootyumserver # cd /wget-yumCentos 源：rootyumserver wget-yum# wget-S-c-r-np-Lhttp:/centos/6.5/foreman 源：rootyumserver wget-yum# wget-Lrootyumserver wget-yum# wget-L-S-c-r-np-S-c-r-npepel 源：rootyumserver wget-yum# wget -S -c -r -np -L HYPERLINK http:/m/epel/6/ http:/m/epel/6/puppetlabs 源：root

4、yumserver wget-yum# wget -S -c -r -np -L https:/y/el/6/openstack 源：rootyumserver wget-yum# wget-Lrootyumserver wget-yum# wget-L-S-c-r-np-S-c-r-np(3).删除不需要的包和文件：rootyumserver wget-yum# find ./ -name index.html* | xarge rm -rfrootyumserver wget-yum# find ./ -name fedora-20 | xarge rm -rf rootyumserver

5、 wget-yum# find ./ -name fedora-19 | xarge rm -rf rootyumserver wget-yum# find ./ -name i386 | xarge rm -rf(4).调整目录结构：rootyumserverrootyumserver rootyumserver rootyumserver rootyumserver rootyumserver rootyumserver rootyumserver rootyumserver rootyumserver rootyumserver rootyumserverwget-yum# mkdir

6、foremanwget-yum# mv yum.theforeman. wget-yum# mv yum.theforeman. wget-yum# rm -rf yum.theforeman./plugins foreman/releases foreman/wget-yum# mv m/epel ./wget-yum# rm -rf mwget-yum# mkdir puppetlabswget-yum# mv /el /puppetlabs/ wget-yum# rm -rfwget-yum# mv rewget-yum# rm -rf re wget-yum# ls.fedorople

7、./re/openstack ./.fedorople.centos epel foreman openstack puppetlabs2）nginx 配置：rootyumserver wget-yum# rpm-ivh ngx.noarch.rpmrootyumserver wget-yum# yum -y install nginx rootyumserver wget-yum# vi /etc/nginx/nginx.conf.1. rootyumserver wget-yum# vi /etc/nginx/nginx.confuser nginx; worker_pro.

11、 制作：icehouse 源码包：(1).rootyumserverwgetase-icehouse-4.src.rpm#(2).创建 padraig 用户和组：rootyumserver # groupadd -g 2000 padraigrootyumserver # 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： rootyumserver # rpm -i rdo-release-icehouse-4.src.rpm修改 .repo 文件，以 rdo-r

12、elease.repo 为例1.2.3.openstack-havananame=OpenStack Havana Re baseurl=/enabled=1 skip_if_unavailable=0 gpgcheck=0itory/openstack/openstack-havana/epel-.8.gpgkey=file:/etc/pki/rpm-gpg /RPM-GPG-KEY-RDO-Havanapriority=98(4).修改 .spec 文件内容： rootyumserver # cd rpmbuild/ rootyumserver rpmbuild#SOURS
