openstack实战

gerr3

一、基础环境

1.控制节点
CentOS6.5 base server + development tools
内存：2G
硬盘：20G及以上
网卡：2块
计算节点

2.配置网络可以上外网(实验ip以10.77.60.227为例)
#vi /etc/sysconfig/network-scripts/ifcfg-eth0
#hostname controller   //设置主机名
#vi /etc/sysconfig/network
  hostname = controller   //修改hostname为controller
#vi /etc/hosts
  10.77.60.227 controller  //配置地址解析
#vi /etc/sysctl.conf
  net.ipv4.ip_forward = 1  //修改0位1  开启ip转发
  net.ipv4.conf.default.rp_filter = 0  //修改1位0  开启反向路径过滤
  net.ipv4.conf.all.rp_filter = 0   //增加此行  开启反向路径过滤
#sysctl -p  //使设置生效


3.关闭iptables和selinux
#service iptables stop  //关闭防火墙
#chkconfig iptables off  //开机不启动
#vi /etc/sysconfig/selinux
  selinux=disabled   //修改selinux为disabled关闭selinux
#shutdown -r now  //重启系统

4.安装epel
#wget http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
#rpm -ivh epel-release-6-8.noarch.rpm

5.安装依赖包

#yum -y install python-pip python-devel gcc gcc-c++ make libtool patch automake libxslt-devel MySQL-python openssl-devel libudev-devel git libvirt-python libvirt qemu-kvm gedit python-numdisplay device-mapper bridge-utils libffi-devel libffi lrzsz


6.下载openstack组件

#wget https://launchpadlibrarian.net/205200136/keystone-2015.1.0.tar.gz

#wget https://launchpadlibrarian.net/205200832/nova-2015.1.0.tar.gz

#wget https://launchpadlibrarian.net/205209595/glance-2015.1.0.tar.gz

#wget https://launchpadlibrarian.net/205201746/horizon-2015.1.0.tar.gz

#wget https://launchpadlibrarian.net/205208455/neutron-2015.1.0.tar.gz

#wget https://launchpadlibrarian.net/205209525/cinder-2015.1.0.tar.gz


7.解压如下软件包
#tar zxf nova-2015.1.0.tar.gz
#tar zxf horizon-2015.1.0.tar.gz
#tar zxf neutron-2015.1.0.tar.gz
#tar zxf glance-2015.1.0.tar.gz
#tar zxf cinder-2015.1.0.tar.gz


8.合并依赖包
#cat */requirements.txt | sort -n | uniq >> openstack.txt
#pip install -r openstack.txt -i http://pypi.v2ex.com/simple   //安装


9.安装mysql和rabbitmq
#yum -y install mysql-server rabbitmq-server
#/usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management  
   //打开rabbitmq组件管理  监听端口15672  5672
#/etc/init.d/rabbitmq-server restart  //重启rabbitmq服务
#/etc/init.d/mysqld restart  //启动mysql
#mysqladmin -uroot password openstack  //设置mysql的密码
#cp /usr/share/mysql/my-medium.cnf /etc/my.cnf  //拷贝mysql的配置模板
#vi /etc/my.cnf
  [mysqld]
   ...
  default-storage-engine = innodb
  collation-server = utf8_general_ci
  init_connect = 'SET NAMES utf8'
  character-set-server = utf8   //加入以上4行,保存退出
#/etc/init.d/mysqld restart  //重启mysql

10.设置开机启动mysql和rabbitmq
#chkconfig mysqld on
#chkconfig rabbitmq-server on


二、实战安装
1.
#lsof -i:3306   //查看mysql端口是否监听
#lsof -i:5672   //查看rabbitmq端口是否监听
#tar zxf keystone-2015.1.0.tar.gz  //解压
#pip install -r requirements.txt -i http://pypi.v2ex.com/simple  //安装keystone依赖
#python setup.py install
