本文介绍如何使用prompt命令自定义MySQL客户端的提示符，展示如何显示当前用户、主机、数据库及时间等信息，并提供通过my.cnf配置文件设置的方法。

prompt命令可以在mysql提示符中显示当前用户、数据库、时间等信息.
例如:
[root@localhost ~]# mysql -uroot -p --prompt="\\u@\\h:\\d \\r:\\m:\\s>"
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 13
Server version: 5.7.18-log MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

root@localhost:(none) 11:11:19>use test
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
root@localhost:test 11:11:22>
root@localhost:test 11:11:24>
root@localhost:test 11:11:24>
root@localhost:test 11:11:25>

也可以把参数加到my.cnf里面,需要重启数据库生效:

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