Despite being able to change password, it is still ignoring the password. Non-root user not affected. Explanation per https://mariadb.com/kb/en/authentication-from-mariadb-104/ Using unix_socket means that if you are the system root user, you can login as root@locahost without a password. This technique was pioneered by Otto Kekäläinen in Debian MariaDB packages and has been successfully used in Debian since as early as MariaDB 10.0. It is based on a simple fact that asking the system root for a password adds no extra security — root has full access to all the data files and all process memory anyway.https://quicktasks.ismael.casimpan.com/post/automysqlbackup-cannot-use-root-credentials-from-mysql-cli/Mon, 15 Oct 2018 12:00:13 +0800https://quicktasks.ismael.casimpan.com/post/automysqlbackup-cannot-use-root-credentials-from-mysql-cli/ 1[root@rh icasimpan]# /usr/local/bin/automysqlbackup /etc/automysqlbackup/rh.conf 2Parsed config file "/etc/automysqlbackup/automysqlbackup.conf" 34# Checking for permissions to write to folders: 5base folder /var/lib ... exists ... ok. 6backup folder /var/lib/automysqlbackup ... exists ... writable? yes.
