使用-pormpt修改提示符。可以在登录时或者在登录后使用prompt选项来修改提示符
(1)使用mysql命令行参数修改提示符
# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 27Server version: 5.6.25 Source distributionCopyright (c) 2000, 2015, Oracle and/or its affiliates.

Type '\c' to clear the current input statement.mysql> # 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 28Server version: 5.6.25 Source distributionCopyright (c) 2000, 2015, Oracle and/or its affiliates.

(2)修改配置文件/etc/my.cnf
[mysql]prompt="\\u@\\h:\\d \\r:\\m:\\s>"
(3)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>
(4)当然可以在在Bash层修改 MYSQL_PS1变量
# export MYSQL_PS1="(\u@\h) [\d]> "# mysql -u root -pEnter password: Welcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 31Server version: 5.6.25 Source distributionCopyright (c) 2000, 2015, Oracle and/or its affiliates.
