1 什么是蜗牛星际请自行百度,我花400块买的,千兆网口的a款,这个机器的配置其实就是个NAS配置的机器,搞不懂为什么那么多人会专门花钱买来挖矿,这机器的CPU浮点计算能力很差的,崩盘了也是理所当然,稍微懂行点儿的恐怕都会有疑问...可惜就没人说真话...又是一个悲伤的故事
以下是a款照片,去电脑城淘的,比市场价贵了百把块钱,但是买之前拆开好好看了,成色很好,基本没怎么用的机器,以下是照片(内部没有拍),商家那里有centos安装镜像和引导工具,所以让其直接给我装了centos 7.2 64bit,然后我直接抱回了家
晚上就用这黑木头HDMI接口接上家里的液晶电视后开搞,直接连接上网线你会发现根本连不上网络,所以首先需要对这个黑疙瘩的网络进行配置
注意修改网卡配置(以下是根据我自己家里的网络修改的网络配置信息,个人家里的可能不同,请注意ifcfg-enp3s0是我的机器装了系统后自动生成的配置文件,每个人安装好后enp后面几个字母不一样,单网卡就是这个的配置文件)
1 | vi /etc/sysconfig/network-scripts/ifcfg-enp3s0 |
修改为

1 | systemctl restart network |
然后更换了阿里源,然后yum update后安装所需的软件,比如screen什么的
然后对外网网站什么的进行ping测试看网络好了没有,比如ping下某东/某宝/某度
不行就reboot下
接下来开始折腾吧,配置好网络后,就可以像其他服务器一样使用xshell登录了,IP就是局域网分配给机器的IP,root账户,密码你自己系统的密码不清楚吗?
手里两个1T硬盘,把其中一个1T的移动硬盘拆出来装进了星际蜗牛,
准备格式化后组LVM卷为以后扩充空间做好准备
由于硬盘之前是用作移动硬盘,分区为NTFS,所以要对硬盘重新格式化分区后再挂载
注意,linux对win系统拆下来的硬盘只能认出MBR引导分区,其他的分期用fdisk -l是看不到的
此处涉及GPT文件格式和parted格式化命令,请自行百度是什么意思
以下为重新格式化后分区的笔记

好了 下次接着写LVM扩展存储空间,争取早日将四个硬盘位全部用完,未完待续
