[chenjl@ipha-dev71-1 yysoft]$ read -p "check run the script is the mysql server? (y/n) " choice check run the script is the mysql server? (y/n) y [chenjl@ipha-dev71-1 yysoft]$ echo $choice y
详细解释：
p是prompt的缩写，指提示信息
read -p "check run the script is the mysql server? (y/n) " choice
以上命令回车后会显示 check run the script is the mysql server? (y/n)
之后用户输入的内容会被保存到choice变量中
