OpenStack Icehouse私有云实战部署前言相信你一定对“云主机”一词并不陌生吧，通过在Web页面选择所需主机配置，即可快速定制一台属于自己的虚拟主机，并实现登陆操作，大大节省了物理资源。但这一过程是如何实现的呢?本文带来OpenStack Icehouse私有云实战部署。OpenStack简介OpenStack 是由网络主机服务商Rackspace和美国宇航局联合推出的一个开源项目，OpenStack的目标是为所有类型的云提供一个易于实施，可大规模扩展，且功能丰富的解决方案，任何公司或个人都可以搭建自己的云计算环境(IaaS)，从此打破了Amazon等少数公司的垄断。架构工作流程OpenStack部署实验环境实验拓扑#各节点时间已同步?#各节点已禁用NetworkManager服务?#各节点已清空防火墙规则，并保存?#各节点已基于hosts实现主机名通信?[root@controller?~]#?cat?/etc/hosts????localhost?localhost.localdomain?localhost4?localhost4.localdomain4?::1?????????localhost?localhost.localdomain?localhost6?localhost6.localdomain6?23???controller?24???compute?25???network?26???block?#Network?Node用于外部网络的接口不能用IP地址，建议使用类似如下配置?#INTERFACE_NAME为实际的网络接口名，例如eth1：?DEVICE=INTERFACE_NAME?TYPE=Ethernet?ONBOOT=yes?BOOTPROTO=none?路由配置Block Storage Node还同时提供路由功能，首先来配置一下路由[root@bolck?~]#?vim?/etc/sysctl.conf????net.ipv4.ip_forward?=?1???[root@bolck?~]#?sysctl?-p?[root@bolck?~]#?iptables?-t?nat?-A?POSTROUTING?-s?/24?-j?SNAT?--to-source?26?[root@bolck?~]#?service?iptables?save?iptables:?Saving?firewall?rules?to?/etc/sysconfig/iptables:[??OK??]?安装配置Keystone安装Keystoneopenstac yum源安装[root@controller?~]#?wget?/openstack-icehouse/rdo-release-icehouse.rpm?[root@controller?~]#?rpm?-ivh?rdo-release-icehouse.rpm 安装并初始化MySQL服务器[root@controller?~]#?yum?install?mariadb-galera-server?-y?[root@controller?~]#?vim?/etc/f???[mysqld]?...?datadir=/mydata/data?default-storage-engine?=?innodb?innodb_file_per_table?=?ON?collation-server?=?utf8_general_ci?init-connect?=?SET?NAMES?utf8?character-set-server?=?utf8?skip_name_resolve?=?ON???[root@controller?~]#?mkdir?/mydata/data?-p?[root@controller?~]#?chown?-R?mysql.mysql?/mydata/?[root@controller?~]#?mysql_install_db?--datadir=/mydata/data/?--user=mysql?[root@controller?~]#?service?mysqld?start?Starting?mysqld:???????????????????????????????????????????[??OK??]?[root@controller?~]#?chkconfig?mysqld?on?[root@controller?~]#?mysql_secure_installation 安装配置Identity 服务[root@controller?~]#?yum?install?openstack-utils?openstack-
