Hi Elena, [root@one server ~]# rpm -qa | grep -iE 'mariadb|mysql' MariaDB-client-10.2.9-1.el7.centos.x86_64 MariaDB-compat-10.2.9-1.el7.centos.x86_64 MariaDB-common-10.2.9-1.el7.centos.x86_64 MariaDB-server-10.2.9-1.el7.centos.x86_64 [root@another server~]# rpm -qa | grep -iE 'mariadb|mysql' pcp-pmda-mysql-3.10.6-2.el7.x86_64 MariaDB-client-10.2.10-1.el7.centos.x86_64 MariaDB-server-10.2.10-1.el7.centos.x86_64 MariaDB-common-10.1.18-1.el7.centos.x86_64 Steps: I did the upgrade in two servers: In both servers (both 10.1), I follow the below steps and got ssame unix-socket not loaded error. set-up repo: curl -sS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash *yum update MariaDB-server MariaDB-client* MariaDB-Client installed successfully, but MariaDB-server thrown error that it couldn't update. then I remove the mariaDb-Server using below command: *yum remove MariaDB-server* then install: *yum install MariaDB-server* then mysql-upgrade: I got the error with unix-socket. Do you think yum update MariaDB-server caused this issue? Do I need to remove and then install, instead of update. Please advise.

All,
Did anyone face issues after upgrading the mariadb from 10.1 to 10.2 to login to root user as shown below:
mysql -u root
I got the error - unix_socket not loaded.
I noticed that the unix_socket authentication is required after the upgrade for root login from localhost. Can anyone confirm whether this is part of the feature after upgrades.
This is strange, upgrade to packages *provided by MariaDB* shouldn't do it. Packages provided by another party could be a different story. Could you please paste the output of rpm -qa | grep -iE 'mariadb|mysql' or alike?
In my previous version:
select user, plugin from mysql.user;
+-----------+------+-------------+ | Host | User | plugin | +-----------+------+-------------+ | localhost | root | | ------------------------------------
After upgrade:
select user, plugin from mysql.user;
+-----------+------+-------------+ | Host | User | plugin | +-----------+------+-------------+ | localhost | root | unix_socket | ---------------------------------------
The other way round is more common -- some variations of 10.1 did set unix_socket authentication for local root and could have it enabled by default, and then after upgrade to regular 10.2 unix_socket would become disabled while root would still require it.
Is it possible that your previous installation points at a different data directory, while the old one that 10.2 now uses had this kind of configuration before?
