If you are new to Linux, some common mistakes are likely to cause you trouble. By knowing them in advance, you can avoid major problems as you get familiar with Linux.

1 install software from different sources

Linux distributions generally have default package management software, such as yum, apt, etc., but sometimes you can compile and install from source code, or install binaries directly. Usually this will not be a problem, but the package management system of the system will not record the software you install, and if other software depends on the software you installed in other ways, it may not be available.

2 ignore updates

This may not be just a problem for Linux system administrators. Many system administrators do not want to do anything else after the system is configured, and think that the system is more stable and secure. Keeping up to date allows your system to constantly fix security vulnerabilities, especially if your server is on the network, you should let the system have an automatic update mechanism.

3 weak root password

Root password is very important, the security level should be higher than the average user, do not enter a short password to save trouble.

4 avoid using the command line

Sometimes the command line is simpler, faster, safer, and more stable. The average desktop user doesn't have to know the command line, but as a system administrator, at least know how to use the command line, master some basic commands, and learn to view manual.

5 does not retain an available kernel

When upgrading the kernel, delete the old kernel, and then encounter problems will be difficult to restore. You should keep the original available kernel and delete it after the new kernel is fully verified to be available.

6 No important files were backed up

If some applications or services are important to you and are not easy to configure, be sure to back up. You can quickly restore these configurations in the event of an accident, such as database, Web server configuration, and so on.

7 the server starts and X is enabled by default

If it is a dedicated server, generally do not need to open the desktop environment, it is recommended that X is not enabled by default, which takes up more resources. If you need a graphical interface, you can start it by executing the startx command at the terminal.

8 do not understand permissions

File permissions are divided into rwx (read, write, execute), do not execute chmod 777 at will to solve the problem of no file permissions. Assign reasonable users, groups, and corresponding permissions to the file according to your needs.

9 Log in as root user

Do not use root as the login user, log in with a normal user, and use su or sudo to switch when you need root permissions. Using root users all the time, it is easy to increase the seriousness of the harm caused by misoperation.

10 ignore log files

Log files are stored under / var/log. Be sure to check these files if you have problems running on your system. You can also use tools such as logwatch to generate reports based on log files and keep track of the health of the system on a regular basis.
