To find MySQL server version, connect to MySQL, then run
select version();
You can also use “mysql –version”
[root@server ~]# mysql --version mysql Ver 14.14 Distrib 5.6.38, for Linux (x86_64) using EditLine wrapper [root@server ~]#
This only show MySQL client version. If you have multiple MySQL server installed or MySQL server is running on another host, this won’t help.
