创建内网OpenStack源(pike版)

环境准备

# CentOS 7 最小化安装

# 关闭, 禁用 firewalld
systemctl stop firewalld
systemctl disable firewalld
firewall-cmd --state

# 关闭, 禁用 selinux
setenforce 0
sed -i '/^SELINUX=.*/c SELINUX=disabled' /etc/selinux/config
grep --color=auto '^SELINUX' /etc/selinux/config

YUM设置

更改YUM缓存路径, 安装完成后不删除已下载软件包

mkdir -p /www/share/tmp
cp /etc/yum.conf{,.bak}
sed -i 's#^keepcache=0#keepcache=1#' /etc/yum.conf
sed -i 's/^cachedir/#cachedir/' /etc/yum.conf
sed -ir '3 icachedir=/www/share/tmp/$basearch/$releasever \n' /etc/yum.conf

配置 yum, epel, openstack 安装源

rm -f /etc/yum.repos.d/*
curl -so /etc/yum.repos.d/Centos-7.repo http://mirrors.aliyun.com/repo/Centos-7.repo
sed -i '/aliyuncs.com/d' /etc/yum.repos.d/Centos-7.repo
yum -y install epel-release
rm -rf /etc/yum.repos.d/epel*
curl -so /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo
sed -i '/aliyuncs.com/d' /etc/yum.repos.d/epel-7.repo

# 手动配置阿里云openstack源(关闭GPG验证 否则软件安装时会报错)
cat <<'EOF' >/etc/yum.repos.d/centos-openstack.repo

更新系统并重启

系统更新完毕后需要重新执行上一步替换软装安装源

yum -y update
reboot

保下载的包

将 /www/share/yum/ 目录下载的包移动到 /www/share/yum

mkdir /www/share/yum
find /www/share/tmp/ -name *.rpm |sed -r 's#.*#mv & /www/share/yum/\n#'|bash

下载安装openstack 用到的包

for Package in $List; do
    yum install -y --downloadonly --downloaddir=/www/share/yum $Package
done

生成数据库文件

yum install -y createrepo
createrepo -pdo  /www/share/yum /www/share/yum

安装 http

yum install -y httpd
cat <<EOF >/etc/httpd/conf.d/share.conf
# http share

<Directory "/www/share">
    Options Indexes FollowSymLinks
    IndexOptions NameWidth=* DescriptionWidth=* FoldersFirst

    Order allow,deny
    Allow from all
    Require all granted
</Directory>
EOF

systemctl restart httpd
systemctl enable httpd

创建repo

cat <<EOF >/www/share/loacl.repo
[local_yum]
name=My_Souce
baseurl=http://192.168.0.2/share/yum/
gpgcheck=0
enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
EOF

添加软件

# 下载没有安装过的包
yum install --downloadonly --downloaddir=/www/share/yum/ -y 包名称

# 下载已经安装过的包
yum reinstall --downloadonly --downloaddir=/www/share/yum/ -y 包名称

# 生成数据库
createrepo -pdo  /www/share/yum /www/share/yum
createrepo --update -pdo /www/share/yum /www/share/yum

客户端使用

curl http://192.168.0.2/share/loacl.repo -o /etc/yum.repos.d/Lan7.repo
