systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

11.查看neutron服务状态

systemctl status neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

netstat -tnlup

一直以来用的都是vim,因为之前都是系统自带的vim没有研究过怎么自己安装,今天趁着刚装完新系统,顺便装下vim. 同样vim也有两种安装方法: 一.yum安装,centos下安装软件最简单的方法了,还能解决依赖问题,首推该方法,缺点是源里面有一些软件并不是其官网上最新的 sudo yum install -y vim 二.源码编译安装,今天重点介绍这种方法,不过也挺简单的 1.通过git下载vim最新版 git clone https://github.com/vim/vim.git 2.解决

Vmware VsPhere下的VM如何安装Hyper-v服务

通过主题我们了解到,今天主要介绍的内容为Vmware VsPhere下的VM如何安装Hyper-v服务的操作介绍,一般做运维的大神们都知道,很多情况下,无法在虚拟环境下再安装虚拟机,理解为虚拟化下的虚拟化,在hyper-v下是不可行的,安装后系统无法启动,但是在vmware下安装的虚拟机下再安装hyper-v服务是可行的,当然模式是无法在虚拟环境下安装虚拟非服务的. 我们首先在vmware vsphere下创建了一个虚拟机,然后安装了windows2012R2的操作系统,然后我们安装window
