The users will be frustrated of the strong password policies and choose worse passwords to meet the password policy.įor instance, a user will add complexity to his/her password by simply adding a number or special character like "1" or "!" to the end or capitalizing the first letter of their password. While this is best for the security, it also could be counterproductive. Some Linux admins put too much restrictions on users to choose a password. Hence, you should not include the aforementioned details in your passwords. An attacker might try to guess the password from these details.

Facebook) and professional networks (E.g.
You might have added some of your personal and most of your educational and professional details in social (E.g. More importantly, never ever use your real name, parents/spouse/kids name, school/college name, or your date of birth in your password. The another important point to remember while choosing a password is to avoid commonly used passwords. In fact, a longer password, even consisting of simpler words or constructs, is much better than a short password with special characters. Passwords that are too short prone to brute force attacks as well as to dictionary attacks using words and commonly chosen passwords. The longer the password, the longer it will take to crack. Password length has been found to be a primary factor in characterizing password strength. I strongly advice you not to go below this limit. In most environments, the recommended password length is 8 characters.Īn eight-character password is recommended because it's long enough to provide adequate security and still short enough for users to easily remember.

In this guide, we will learn how to implement some important Linux password policies using Pluggable Authentication Method, shortly known as PAM, in order to strengthen your Linux system's security.īefore getting into the topic, I'd like to list a few important key elements to remember before setting up the password policies. Because, so many system breaches are happened due to weak passwords. Hopefully, this is solution helped you to resolve “ Unknown collation: ‘utf8mb4_unicode_520_ci’” issue with MySQL databases.As a System administrator, you must set a strong password for the users and enforce a strong password policy. That’s it, Now the database is successfully restored without any errors! sed -i 's/utf8mb4_unicode_520_ci/utf8_general_ci/g' backup.sql sed -i 's/CHARSET=utf8mb4/CHARSET=utf8/g' backup.sql The Linux system users can use the sed command to replace text in files directly. Save the backup file and restore the database. With: ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_general_ci Replace the below string: ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_520_ci Also, if you found “ CHARSET=utf8mb4“, replace this with “ CHARSET=utf8“. Edit the database backup file in text editor and replace all occurrences of “ utf8mb4_unicode_520_ci” with “ utf8mb4_general_ci“.
To resolve this issue, I did a little change in the backup file. So we find out that the destination server doesn’t support the ‘utf8mb4_unicode_520_ci’ collation. The Solution:Īfter searching for the error, I found that the MySQL server running on the other server is an older version than the source. The collation id may differ based on the MySQL version.Įrror message: Error 1273 (HY000) at line 36 Unknown collation: 'utf8mb4_unicode_520_ci' Let’s see the problem and solution to the issue faced recently: The Problem:ĭuring the migration of a WordPress application, I faced the following error with the restoration of the MySQL database. In this tutorial, we are discussing an error faced during database restoration on another server. A collation is a set of rules that defines how to compare and sort character strings in a database server.
