临时不退出方法：

mysql> prompt (\u@\h) [\d]>\_
PROMPT set to '(\u@\h) [\d]>\_'
(root@localhost) [(none)]>

(root@localhost:mysql3306.sock) [(none)]> prompt (\u@\h:\p) [\d]>\_
PROMPT set to '(\u@\h:\p) [\d]>\_'
(root@localhost:mysql3306.sock) [(none)]>

最终方法：

　考虑到官方文档中提示会读取到/etc/my.cnf和~/.my.cnf下的prompt，就容易联想到是不是mysql客户端就只能读取到默认路径下的[mysql]？

　　继续做以下尝试：

[root@dd ~]# /usr/local/mysql/bin/mysql --verbose --help | grep my.cnf

                      order of preference, my.cnf, $MYSQL_TCP_PORT,

/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf

[root@zstedu ~]# cat /etc/my.cnf
[mysql]
prompt=\\u@\\h:\\p [\\d]>
[root@zstedu ~]# mysql -S /tmp/mysql3306.sock -p
