个性化设置 MySQL prompt 提示符

     下面谈 4 种方法
     
     

     ㈠ 在 Bash 层修改 MYSQL_PS1 变量

[root@localhost ~]# export MYSQL_PS1="(\u@\h) [\d]> "[root@localhost ~]# mysql -u root -pEnter password: Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 73Server version: 5.5.28 MySQL Community Server (GPL)Copyright (c) 2000, 2012, Oracle and/or its affiliates.

Type '\c' to clear the current input statement.(root@localhost) [(none)]> use test;Database changed(root@localhost) [test]> 

     ㈡ MySQL 命令行参数

[root@localhost ~]# mysql -u root -p --prompt="(\u@\h) [\d]> "Enter password: Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 74Server version: 5.5.28 MySQL Community Server (GPL)Copyright (c) 2000, 2012, Oracle and/or its affiliates.

Type '\c' to clear the current input statement.(root@localhost) [(none)]> 

     ㈢ 配置文件 /etc/my.cnf

[mysql]prompt=(\\u@\\h) [\\d]>\\_ 又或者：[mysql]prompt="\\r:\\m:\\s> "要多加一个反斜线\.

     ㈣ 在 MySQL 中使用 prompt 命令

mysql> prompt \r:\m:\s\P>\_PROMPT set to '\r:\m:\s\P>\_'08:20:42pm> promptReturning to default PROMPT of mysql> mysql>
