本篇文章是對mysql中的prompt進(jìn)行了詳細(xì)的分析介紹，需要的朋友參考下

想必大家在命令行操作mysql的時(shí)候會(huì)十分發(fā)愁現(xiàn)在的操作的是那個(gè)數(shù)據(jù)庫吧，至少我就糾結(jié)過，可能您會(huì)說我打一條命令不就知道了，是的這樣做確實(shí)可以的。
可是今兒給大家介紹個(gè)好用的命令--prompt

復(fù)制代碼代碼如下:

[root@fsailing1 ~]# 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 378
Server version: 5.0.95 Source distribution

owners.

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

root@localhost:(none) 08:23:32>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 08:23:44>exit;

這樣做的好處就是讓我們大家在操作數(shù)據(jù)庫時(shí)更加方便快捷。

您也可以在在my.cnf配置文件里進(jìn)行配置：

復(fù)制代碼代碼如下:

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

default-character-set=utf8

復(fù)制代碼代碼如下:

[root@fsailing1 ~]# vim /etc/my.cnf
[root@fsailing1 ~]# service mysqld restart
停止 MySQL： [確定]
啟動(dòng) MySQL： [確定]
[root@fsailing1 ~]# mysql -uroot -p
Enter password:
