yum repolist
3. Install rsnapshot.
yum install rsnapshot
yum install epel-release
2. Update the repo with the command below.

For Linux system administrators, you must understand the ps aux command. If you want to be a Linux system administrator, or you are a Linux user, you should understand this command. ps is process status For short, anyone can find out what kind of program is running on the system and how the status is executed through this command. I saw some programs that should not appear, maybe the system was hacked and used to mine🥹
Not sure who will use it, but I encountered it myself, because my home is a floating IP. A software I installed cannot detect that the ppp0 network card is an external network, so changing the name can trick him into successfully installing it.
Recently, I just started using Google's GCE, and I will record the official Goolge documentation on how to generate a key for the instance to use. The -C comment here will use the name of the logged-in user, and the -t will use rsa.
