随着管理mysql服务器越来越多，同样的mysql>的提示符有可能会让你输入错误的命令到错误的数据库，这时候需要巧用mysql的提示符，这 是我的提示符root@localhost(mysql) 08:55:21> 用prompt命令实现(适用于windows和linux环境)

mysql>prompt \u@\h(\d) \r:\m:\s>
\u:连接用户
\h:连接主机
\d:连接数据库
\r:\m:\s:显示当前时间
mysql>prompt \u@\h(\d) \r:\m:\s>
root@localhost(mysql) 08:55:21> status

设置方式=>

<1>mysql -uroot -p --prompt="(\\u@\\h)[\\d] \\r:\\m:\\s>"

<2>mysql> prompt (\u@\h)[\d]\r:\m:\s>

<3>也可以在在my.cnf配置文件里进行配置：

[mysql]/[client]

prompt="(\\u@\\h)[\\d] \\r:\\m:\\s>"

default-character-set=utf8
