OpenStack云主机配置VIP

在OpenStack中默认由于安全组策略限制，云主机只响应自己的iP地址请求，如果需要做HA，可以用以下两种方式实现

1、增加allow_address_pairs属性

# neutron port-list |grep 10.xxx.51.50

2、关闭neutron port的安全组特性

 # neutron port-update --no-security-groups $port_id
 # neutron port-update $port_id --port-security-enabled=False

创建 OpenStack云主机 [六] openstack 时间:2016年11月28日创建虚拟网络创建m1.nano规格的主机(相等于定义虚拟机的硬件配置)生成一个密钥对(openstack的原理是不使用密码连接,而是使用密钥对进行连接) 增加安全组规则(用iptables做的安全组) 启动一个实例(使用命令启动,启动虚拟机有三种方式:1.命令CLI 2.api 3.Dashboard)其实Dashboard也是通过api进行连接块设备存储编排共享文件系统虚拟网络分为提供者网络和私有网络

KVM定制OpenStack云主机

KVM定制OpenStack云主机如何定制化OpenStack云主机?从去年10月份刚开始接触OpenStack,到现在也有一年了.虽说目前只是停留在用它,对它的一些组件简单的了解,但谈到制作出一个OpenStack云主机的镜像还真不会.今年年初因为一个比赛需要给云主机安装tomcat.ssh等服务,一头雾水,网上查资料.也有正确的资料,但对于我来说似乎也不管用.记得当时是用libvirt的virsh来实现的.而且云主机用的是网上下载的ubuntu14.04的server版本,而且又看到网上说

Python批量给云主机配置安全组

这几年对运维人员来说最大的变化可能就是公有云的出现了,我相信可能很多小伙伴公司业务就跑在公有云上, 因为公司业务关系,我个人接触公有云非常的早,大概在12年左右就是开始使用亚马逊云,后来逐渐接触到国内的阿里,腾讯云等,随着公司业务往国内发展,这几年我们也使用了很多国内的公有云厂商,所以在云运维方面也积累了一些经验,从传统的物理机到公有云运维,我个人认为最大的问题就是你能不能用公有云的思路去思考去实现一个安全稳定.可伸缩和经济的业务构架,云运维是有别与传统运维的,比如说了解公有云的都知道安全组的概
