The right way to manage patches

The reason I decided so quickly to continue the "System Administration 101" article series again is because I realized that some Linux system administrators are no different than Windows system administrators when it comes to patch management. To be honest, it's even worse in some areas (it especially prides itself on running time). Therefore, this article will cover the basic concepts of patch management under Linux, including what good patch management is, some related tools you may use, and how the entire patch installation process is performed. What is patch management? By patch management, I mean the systems you deploy to upgrade the software on your servers, not just to update the software to the latest and greatest cutting-edge version. Even for "stability" like Debian

There are three types of variable classifications of environment variables in Shell.

Variable classification of unixshell There are three types of variables in the Shell: internal variables, environment variables, and user variables. Internal variables: provided by the system, no need to define linux to modify user environment variables. Introduction to linux, environment variables cannot be changed: system provides linux to modify user environment variables, no need to define linux software, they can be changed, and user variables can be converted to environment variables with the help of export. User variables : User-defined, can be changed (1) Internal variables (system variables, environment variables, parameter variables, predefined variables) Internal variables are a special type of variables provided by Linux.

What files do Linux environment variables come from?

In the Linux environment, after the LinuxShell login is successful, Linux will obtain a series of data from the file for the login. This data will be used in individual instructions or individual programs. That data is called the LinuxShell runtime environment. Data in the environment can be roughly divided into four types: environment variables, Shell variables, aliases, and Shell functions. Among them, Shell variables, aliases, and Shell functions will not be explained in detail here. What are the environment variables? You can directly use the printenv command without parameters to output the environment variables of the current session and the values of the environment variables. If parameters are added, the value of a certain variable is output. If it were more convenient to view
