· --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.
你想要什么?详细或版本?
如果您需要服务器端版本,请连接到服务器,发送查询status;
您应该使用完整的args连接服务器,例如:
> mysql --user=user --password=password --host=serverip
或将参数放在~/.my.cnf
就像我的一样:
[mysql]
default-character-set=utf8
prompt="\\u@\\h \\r:\\m:\\s > "
user=user
password=DqvQ86ls1VQit617C
host=127.0.0.1
port=3306
