搭建本地OpenStack源
1、安装系统
配置以下：
Centos 7.6 虚拟机一台
CPU：双核双线程
内存：2G
硬盘：30G系统盘+300G挂载盘
安装桌面-开发工具
搭建本地OpenStack源
搭建本地OpenStack源
关闭防火墙以及核心防御
2、同步OpenStack生产环境源
备份系统自带的yum源html

[root@localhost network-scripts]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# mkdir bak
[root@localhost yum.repos.d]# mv C* bak/
[root@localhost yum.repos.d]# hostnamectl set-hostname opstkyumy
[root@localhost yum.repos.d]# su
[root@opstkyumy yum.repos.d]#

编辑阿里云Centos 7 官方源和OpenStack源
编辑阿里云Centos 7 官方源和Open将相关的repo文件复制到/etc/yum.repos.d/下
CentOS-QEMU-EV.repo
epel.repo
openstack.repo
CentOS-Base.repo
CentOS-Storage-common.repo
nginx.repoStack源linux

[root@opstkyumy yum.repos.d]# mkdir /abc
[root@opstkyumy yum.repos.d]# mount.cifs //192.168.254.1/linuxs /abc
Password for root@//192.168.254.1/linuxs:  
[root@opstkyumy yum.repos.d]# cp /abc/yum.repos.d/* .
[root@opstkyumy yum.repos.d]# ls
bak               CentOS-QEMU-EV.repo         epel.repo   openstack.repo
CentOS-Base.repo  CentOS-Storage-common.repo  nginx.repo

检测阿里云源是否正常nginx

[root@opstkyumy yum.repos.d]# yum repolist

安装相关软件
yum-utils：reposync同步工具
createrepo：编辑yum库工具 作依赖关系用
plugin-priorities：控制yum源更新优先级工具，这个工具能够用来控制进行yum源检索的前后顺序，建议能够用在client端c++

[root@opstkyumy yum.repos.d]# yum install -y wget make cmake gcc gcc-c++ pcre-devel zlib-devel openssl openssl-devel createrepo yum-utils

建立源目录，挂载数据盘，将源同步到本地目录swift

[root@opstkyumy yum.repos.d]# mkdir /data
[root@opstkyumy yum.repos.d]# fdisk -l

开始同步，将源同步到本地目录，过程较长，耐心等待
能够用 repo -r --repoid=repoid指定要查询的repo id，能够指定多个（# reposync -r base -p /data #这里同步base目录到本地）
更新新的rpm包
reposync -np /datavim

[root@opstkyumy ~]# reposync -p /data
[root@opstkyumy data]# ls
base            epel    nginx             openstack-rocky  openstack-train
centos-qemu-ev  extras  openstack-queens  openstack-stein  updates
[root@opstkyumy data]# ls base/
Packages    //里面都是RPM包
[root@opstkyumy data]# ls epel/
Packages
[root@opstkyumy data]# ls nginx/
RPMS
[root@opstkyumy data]# ls openstack-rocky/  //里面都是RPM包
[root@opstkyumy data]# ls centos-qemu-ev/
[root@opstkyumy data]# ls extras/
Packages
[root@opstkyumy data]# ls updates/
Packages

3、解决OpenStack软件环境依赖关系
1.建立软件依赖关系库centos

[root@opstkyumy ~]# createrepo -po /data/base/ /data/base/
[root@opstkyumy ~]# createrepo -po /data/extras/ /data/extras/
[root@opstkyumy ~]# createrepo -po /data/updates/ /data/updates/
[root@opstkyumy ~]# createrepo -po /data/epel/ /data/epel/
[root@opstkyumy ~]# createrepo -po /data/openstack-queens/ /data/openstack-queens/
[root@opstkyumy ~]# createrepo -po /data/openstack-rocky/ /data/openstack-rocky/
[root@opstkyumy ~]# createrepo -po /data/openstack-stein/ /data/openstack-stein/
[root@opstkyumy ~]# createrepo -po /data/openstack-train/ /data/openstack-train/
[root@opstkyumy ~]# createrepo -po /data/centos-qemu-ev /data/centos-qemu-ev/
[root@opstkyumy ~]# createrepo -po /data/nginx /data/nginx

2.更新源数据bash

[root@localhost ~]# createrepo --update /data/base
[root@localhost ~]# createrepo --update /data/extras
[root@localhost ~]# createrepo --update /data/updates
[root@localhost ~]# createrepo --update /data/epel
[root@localhost ~]# createrepo --update /data/openstack-queens
[root@localhost ~]# createrepo --update /data/openstack-rocky
[root@localhost ~]# createrepo --update /data/openstack-stein
[root@localhost ~]# createrepo --update /data/openstack-train
[root@localhost ~]# createrepo --update /data/centos-qemu-ev
[root@localhost ~]# createrepo --update /data/nginx

3.更新yum脚本app

[root@opstkyumy ~]# mkdir /data/script
[root@opstkyumy ~]# vim /data/script/centos_openstack_yum_update.sh
#!/bin/bash
echo 'Updating Aliyum Source'
DATETIME=`date +%F_%T`
exec > /var/log/aliyumrepo_$DATETIME.log
     reposync -np /data
if [ $? -eq 0 ];then
      createrepo --update /data/base
      createrepo --update /data/extras
      createrepo --update /data/updates
      createrepo --update /data/epel
      createrepo --update /data/openstack-queens
      createrepo --update /data/openstack-rocky
      createrepo --update /data/openstack-stein
      createrepo --update /data/openstack-train
      createrepo --update /data/centos-ceph-nautilus
      createrepo --update /data/centos-nfs-ganesha28
      createrepo --update /data/centos-ceph-luminous
      createrepo --update /data/centos-qemu-ev
      createrepo --update /data/nginx
      createrepo --update /data/ceph-noarch
    echo "SUCESS: $DATETIME aliyum_yum update successful"
  else
    echo "ERROR: $DATETIME aliyum_yum update failed"
fi
[root@opstkyumy ~]# chmod +x /data/script/centos_openstack_yum_update.sh

4.将脚本加入到定时任务中ide

将脚本加入到定时任务中
[root@opstkyumy ~]# crontab -e
00 13 * * 6 [ $(date +%d) -eq $(cal | awk 'NR==3{print $NF}') ] && /bin/bash /data/script/centos_openstack_yum_update.sh

4、发布本地OpenStack-yum源仓库
1.安装nginx开启目录权限保证本地机器能够直接本地yum源

[root@opstkyumy ~]# groupadd nginx
[root@opstkyumy ~]# useradd -r -g nginx -s /bin/false -M nginx
[root@opstkyumy ~]# yum -y install nginx  
[root@opstkyumy ~]# vim /etc/nginx/nginx.conf 
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  opstkyumy;
        root         /data;
        location / {
            autoindex on;
            autoindex_exact_size off;
            autoindex_localtime on;
            charset utf-8,gbk;
            index index.html;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}
[root@opstkyumy nginx]# systemctl start nginx
[root@opstkyumy nginx]# systemctl stop firewalld
[root@opstkyumy nginx]# systemctl disable firewalld
[root@opstkyumy nginx]# setenforce 0
setenforce: SELinux is disabled
[root@opstkyumy nginx]# systemctl enable nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.servi

搭建本地OpenStack源
5、OpenStack客户端部署本地yum源仓库
配置网卡

[root@localhost ~]# ifconfig

搭建私网仓库

[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
bak  local.repo
[root@localhost yum.repos.d]# rm -rf local.repo 
[root@localhost yum.repos.d]# vim openstack.repo

[root@localhost yum.repos.d]# yum makecache

测试是否能够下载RPM包

[root@localhost yum.repos.d]# cd /opt
[root@localhost opt]# ls
rh
[root@localhost opt]# yumdownloader openstack-swift-account
[root@localhost opt]# ll
总用量 24
-rw-r--r--  1 root root 21264 10月 25 22:27 openstack-swift-account-2.23.1-1.el7.noarch.rpm
drwxr-xr-x. 2 root root     6 10月 31 2018 rh

能够正常下载，部署成功
6、配置阿里云时间同步服务、配置NTP服务
配置同步阿里时钟，在本地源配置

[root@opstkyumy data]# yum -y install ntpdate
[root@opstkyumy data]# ntpdate ntp.aliyun.com
19 Feb 23:19:01 ntpdate[54480]: adjust time server 203.107.6.88 offset -0.002603 sec
[root@opstkyumy ~]# crontab -e 
*/30 * * * * /usr/sbin/ntpdate ntp.aliyun.com >>/var/log/ntpdate.log
//能够先把时间调小一点，测试是否生效
[root@opstkyumy data]# cd /var/log/
[root@opstkyumy log]# systemctl restart crond
[root@opstkyumy log]# systemctl enable crond
[root@opstkyumy log]# ll | grep "ntp"
-rw-r--r--  1 root   root       84 Feb 19 23:22 ntpdate.log
[root@opstkyumy log]# tail -f /var/log/ntpdate.log
19 Feb 23:22:09 ntpdate[57911]: adjust time server 203.107.6.88 offset 0.005077 sec
19 Feb 23:23:09 ntpdate[59092]: adjust time server 203.107.6.88 offset -0.0019

NTP时钟同步完毕，便开始安装NTP服务，让别人同步本身

[root@opstkyumy log]# yum -y install ntp
[root@opstkyumy log]# vim /etc/ntp.conf
  8 restrict default nomodify notrap 
 17 restrict 192.168.254.0 mask 255.255.255.0 nomodify notrap
 //原有的21-24行删除，加入下面配置
 21 fudeg 127.127.1.0 stratum 10
 22 server 127.127.1.0

NTP设置开机自启而后reboot以后出现没有自启动的bug解决：
经过禁止chronyd服务开启自启动以后再将系统重启
chronyd是linux自带的时间服务

[root@opstkyumy log]# systemctl disable chronyd.service
Removed symlink /etc/systemd/system/multi-user.target.wants/chronyd.service.
[root@opstkyumy log]# systemctl restart ntpd
[root@opstkyumy log]# systemctl enable ntpd
Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service.
