Any Idea why this is happening?

I only got an error on mysql -v command

Thank you.

回答1:

   ·   --verbose, -v

       Verbose mode. Produce more output about what the program does. This option can be given multiple times to produce more and more output. (For example, -v -v -v produces table output format even in
       batch mode.)

   ·   --version, -V

       Display version information and exit.

what you want ? verbose or version ?

if you want server side version, connect to server, send query status;

You should connect server with full args, example:

> mysql --user=user --password=password --host=serverip

or put the args on ~/.my.cnf

just like mine:

[mysql]
default-character-set=utf8
prompt="\\u@\\h \\r:\\m:\\s > "
user=user
password=DqvQ86ls1VQit617C
host=127.0.0.1
port=3306
