一、openstack（ocata）本地yum源的建立：
1、配置yum缓存：
vi /etc/yum.conf 把yum.conf配置改为：[main]cachedir=/var/cache/yum/$basearch/$releaseverkeepcache=1
2、指定Ocata镜像源
yum install -y epel-releaseyum list all|grep openstackyum install centos-release-openstack-ocata.noarch -y
3、安装所有ocata版的软件包(下面有用python3脚本将源的文件全下载下来)：
vi openstack_yum.sh#!/bin/bashyum installl -y createrepo yum-plugin-priorities yum install ntp rabbitmq-server memcached python-memcached -yyum install python-openstackclient openstack-selinux mariadb mariadb-server python2-PyMySQL -yyum install openstack-keystone httpd mod_wsgi -y yum -y install openstack-glance python-glanceclient -yyum install -y openstack-nova-api openstack-nova-placement-api openstack-novaconductor \openstack-nova-console openstack-nova-novncproxy openstack-novascheduler \python-novaclient yum install -y openstack-nova-compute sysfsutilsyum install -y openstack-neutron openstack-neutron-ml2 python-neutronclient yum install -y ebtables openstack-neutron-openvswitch ipsetyum install -y openstack-dashboardyum install -y openstack-cinder targetcli python-oslo-db MySQL-python lvm2 python-keystoneyum install -y openstack-swift-proxy python-swiftclient python-keystoneauth-token \python-keystonemiddleware memcachedyum install -y xfsprogs rsync yum install -y openstack-swift-account openstack-swift-container \openstack-swift-objectyum install -y openstack-heat-api openstack-heat-api-cfn openstack-heatengine \python-heatclientyum install -y mongodb-server mongodbyum install -y openstack-ceilometer-api openstack-ceilometer-collector \openstack-ceilometer-notification openstack-ceilometer-central \openstack-ceilometer-alarm \python-ceilometerclientyum install -y openstack-ceilometer-compute python-ceilometerclient pythonpecanyum install -y openstack-trove python-troveclientyum install -y openstack-sahara python-saharaclient ./openstack_yum.sh
3、复制下载过来的软件包：
mkdir /opt/ocata_yumcp -R /var/cache/yum/x86_64/7/ /opt/ocata_yum/yum install createrepocreaterepo /opt/ocata_yum/
4、安装nginx：
1、安装依赖包：yum install -y pcre pcre-devel openssl openssl-devel gcc wgetgroupadd -r nginxuseradd -r -g nginx -s /bin/false -M nginx2、安装nginx：cd /usr/loca/srcwget http://nginx.org/download/nginx-1.8.0.tar.gztar -zxvf nginx-1.8.0.tar.gzcd nginx-1.8.0./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcremake && make install3、配置nginx.conf
user nginx;worker_processes 1;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; charset utf-8; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; sendfile on; gzip on; include vhosts/*.conf;} mkdir /usr/local/nginx/conf/vhosts/ vi /usr/local/nginx/conf/vhosts/ocata.conf
server { listen 80; server_name localhost; index index.html index.php index.htm; access_log /var/log/nginx/access.log main; error_log /var/log/nginx/error.log; location /{ root /opt/; autoindex on; autoindex_exact_size off; autoindex_localtime on; }} 4、启动nginx /usr/local/nginx/sbin/nginx -t /usr/local/nginx/sbin/nginx echo "/usr/local/nginx/sbin/nginx" >> /etc/rc.local
5、配置使用yum源的机器：
配置yum源：vi /etc/yum.repos.d/openstack_ocata.repo [ocata]name=ocata_rpmbaseurl=http://192.168.71.21/ocata_yum/enabled=1gpgcheck=0[updates]name=kevin updatebaseurl=http://192.168.71.21/ocata_yum/gpgcheck=0enabled=1mv CentOS-Base.repo CentOS-Base.repo.bakyum clean allyum makecache
python3下载网易源的软件包：
