篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了搭建本地OpenStack源相关的知识，希望对你有一定的参考价值。
搭建本地OpenStack源一、安装系统
配置如下：
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
关闭防火墙以及核心防护
二、同步OpenStack生产环境源
备份系统自带的yum源
[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
[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
[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 做依赖关系用
plugin-priorities：控制yum源更新优先级工具，这个工具可以用来控制进行yum源检索的先后顺序，建议可以用在client端
[root@opstkyumy yum.repos.d]# yum install -y wget make cmake gcc gcc-c++ pcre-devel zlib-devel openssl openssl-devel createrepo yum-utils创建源目录，挂载数据盘，将源同步到本地目录
[root@opstkyumy yum.repos.d]# mkdir /data
[root@opstkyumy yum.repos.d]# fdisk -l

可以用 repo -r --repoid=repoid指定要查询的repo id，可以指定多个（# reposync -r base -p /data #这里同步base目录到本地）
更新新的rpm包
reposync -np /data
[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三、解决OpenStack软件环境依赖关系
1.创建软件依赖关系库
[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/nginx2.更新源数据
[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/nginx3.更新yum脚本
[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.sh4.将脚本加入到定时任务中
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 四、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可以直接本地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
五、OpenStack客户端部署本地yum源仓库
配置网卡
[root@localhost ~]# ifconfig

[root@localhost yum.repos.d]# cd /opt
[root@localhost opt]# ls

[root@localhost opt]# yumdownloader openstack-swift-account
[root@localhost opt]# ll
总用量 24

drwxr-xr-x. 2 root root 6 10月 31 2018 rh可以正常下载，部署成功
六、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
//可以先把时间调小一点，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 -0.0019NTP时钟同步完毕，便开始安装NTP服务，让别人同步自己
[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 127.127.1.0NTP设置开机自启然后reboot之后出现没有自启动的bug解决：
通过禁止chronyd服务开启自启动之后再将系统重启
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.部署全部完成
