3. Remote system settings
Using the CenOS system,
Download the new CentOS-Base.repo to /etc/yum.repos.d/
To detect whether the CenOS system has a network, you can use ping www.baidu.com
Ctrl +c final short
If you use the desktop version, you can add ping -n www.baidu.com
Terminate with ctrl + c
Install the download tool wget
If you use the root user, you can use the following command
yum install wget -y
If you are an ordinary user, you need to add sudo for authorization
sudo yum install wget -y
Change the yum source and download the installation source of the software.
PS: Install both (1) and (2). Alibaba Cloud will do.
Alibaba Cloud: repo source link
(1) Change the yum source, download the installation source of the software, and provide it officially.
Method 1 (with hints, officially provided by CentOS, this is the source Base): curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
Method 2 (no prompt, one more -s): curl -s -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
(2) Change the yum source and download the installation source of the software (this is also installed, provided by a third party, and the download software is relatively complete; remove the -s to see the installation prompt, you can skip it, this is epel) curl -s -o
/ etc/yum.repos.d/epel.repo http://mirrors.aliyun..com/repo/epel-7.repo
XShell7 connects to the virtual machine
The connection always fails. I found a lot of methods on the Internet. If it doesn’t work, I think that as long as the two terminals can ping each other, it will be fine. If the firewall in the virtual machine is closed and ssh is turned on, it can be connected.
The next chapter introduces the connection of XShell7 to the virtual machine, and the connection is successful
