然后原来的一元机就换系统了……0x00.修改主机名
如果在创建实例时高级设置里指定了主机名，则会自动配置
1 | [root@txy ~]# cat /etc/hosts |
否则，手动更改
1 | [root@txy ~]# hostnamectl set-hostname txy.yuangezhizao.cn |
0x01.修改ssh端口
改成非22端口防止爆破
1 | [root@txy ~]# vim /etc/ssh/sshd_config |
注意一定要新开个shell测试新端口是否生效，生效则可关闭旧shell，否则需重新配置
0x02.软件
1 | yum update -y |
nfs-utils：暂时10G免费
腾讯云文件系统COSFS：https://github.com/tencentyun/cosfs

0x03.挂载第三方存储

安装编译工具
yum groupinstall 'Development Tools' -y1
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel -y
这里面有一个包很关键
libffi-devel，因为只有3.7才会用到这个包，如果不安装这个包的话，在make阶段会出现如下的报错：# ModuleNotFoundError: No module named '_ctypes'下载源码包
wget --no-check-certificate https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tar.xz

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
