问题描述

bitnami@ip-10-99-67-123:~/.rvm/gems$ mysql -v

知道为什么会这样吗?

我只在 mysql -v 命令上出错

谢谢.

推荐答案

   ·   --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?详细还是版本?

what you want ? verbose or version ?

如果你想要服务器端版本，连接到服务器，发送查询status;

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

您应该使用完整的参数连接服务器，例如:

You should connect server with full args, example:

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

或者把参数放在 ~/.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
