由 时光总嘲笑我的痴心妄想 提交于 2019-12-13 20:19:14
问题 I am creating virtualbox redhat box with packer with the template attached below. Everything is fine except that when the host is created and rebooted, the eth0 network adapter does not start as it is created with ONBOOT=no in /etc/sysconfig/network-scripts.

Linux的使用环境也日趋成熟，各种开源产品络绎不绝，大有百花齐放的盛景，那么当Linux落地企业，回归工作时，我们还要面对这Linux运维方面的诸多问题，今天我们特意组织一场有关Linux 在企业运用当中交流分享活动。本次活动内容丰富，在此我们进行一下系统的梳理。 一 Linux选择 选择一个适合自身企业的Linux版本系列和主流版本还是相对不容易的，下面我们来介绍一下在选择时各企业所参考的依据： RedHat和CentOS 选择红帽子系列产品，以centos为主，主要考虑有几个方面： centos是redhat的编译版本，基本上没有什么大的变动 现在很多环境都是集群环境，包括web集群，中间件集群，rac群集等等，OS层面本身的高可用系数已经不是100%要求那么高了。 主流版本生命周期比较长，比较适合一个硬件的生命周期管理，基本上安装一次直到设备报废了。 批量安装部署方便，硬件和软件兼容性都挺好。 版本主要使用6版本，新上应用可以全面考虑升级使用7版本 SuSe 使用的Suse Linux Enterprise版，主要考虑因素如下： 1、该发行版本性能和稳定性比较突出 2、对客户的技术支持体系较为完备，服务响应较快（这基本上是最重要的因素） 3、对开源社区如openstack等生态拥抱得也较好。 4、版本主要是SUSE11 较多。 二 安装部署 方式：U盘，光盘和网络安装

It also requires f2py, which I am unsure of how to get. Any suggestions for easier installation? I had been
