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/$basearch/$releasever
keepcache=1
2、指定Ocata镜像源
yum install -y epel-release
yum list all|grep openstack
yum 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/bash
yum installl -y createrepo yum-plugin-priorities
yum install ntp rabbitmq-server memcached python-memcached -y
yum install python-openstackclient openstack-selinux mariadb mariadb-server python2-PyMySQL -y
yum install openstack-keystone httpd mod_wsgi -y
yum -y install openstack-glance python-glanceclient -y
yum 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 sysfsutils
yum install -y openstack-neutron openstack-neutron-ml2 python-neutronclient
yum install -y ebtables openstack-neutron-openvswitch ipset
yum install -y openstack-dashboard
yum install -y openstack-cinder targetcli python-oslo-db MySQL-python lvm2 python-keystone
yum install -y openstack-swift-proxy python-swiftclient python-keystoneauth-token \
python-keystonemiddleware memcached
yum install -y xfsprogs rsync
yum install -y openstack-swift-account openstack-swift-container \
openstack-swift-object
yum install -y openstack-heat-api openstack-heat-api-cfn openstack-heatengine \
python-heatclient
yum install -y mongodb-server mongodb
yum install -y openstack-ceilometer-api openstack-ceilometer-collector \
openstack-ceilometer-notification openstack-ceilometer-central \
openstack-ceilometer-alarm \
python-ceilometerclient
yum install -y openstack-ceilometer-compute python-ceilometerclient pythonpecan
yum install -y openstack-trove python-troveclient
yum install -y openstack-sahara python-saharaclient
./openstack_yum.sh
3、复制下载过来的软件包：
mkdir /opt/ocata_yum
cp -R /var/cache/yum/x86_64/7/ /opt/ocata_yum/
yum install createrepo
createrepo /opt/ocata_yum/
4、安装nginx：
1、安装依赖包：
yum install -y pcre pcre-devel openssl openssl-devel gcc wget
groupadd -r nginx
useradd -r -g nginx -s /bin/false -M nginx
2、安装nginx：
cd /usr/loca/src
wget http://nginx.org/download/nginx-1.8.0.tar.gz
tar -zxvf nginx-1.8.0.tar.gz
cd 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-pcre
make && make install
3、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;
}
nginx.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;
}
}ocata.conf
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_rpm
baseurl=http://192.168.71.21/ocata_yum/
enabled=1
gpgcheck=0
[updates]
name=kevin update
baseurl=http://192.168.71.21/ocata_yum/
gpgcheck=0
enabled=1
mv CentOS-Base.repo CentOS-Base.repo.bak
yum clean all
yum makecache
python3下载网易源的软件包：
