[英]Bash user input Mysql login
Will start with what I am trying to accomplish. 从我要完成的事情开始。 I wrote up a menu script to add a new database and echo back to screen the results. 我写了一个菜单脚本来添加一个新的数据库并回显屏幕结果。 But can't seem to get it to login with a variable. 但是似乎无法使用变量登录。
Heres the part I am having problems with: 这是我遇到的问题:
#!/bin/bash
while [[ "$yn" != "Yes" && "$yn" != "Y" && "$yn" != "y" && "$yn" != "yes" ]]; do
echo " Please, type password for root user. #"
read -r mysqlrp
echo " You have entered $mysqlrp as your MySQL password #"
echo " Is this correct? (Yes or No) #"
read yn
done
mysql -u root -p$mysqlrp
have also tried: 也尝试过:
mysql -u root -p${mysqlrp}
as well as mysql -u root -p'${mysqlrp}'
以及mysql -u root -p'${mysqlrp}'
I get the following: 我得到以下内容:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
even though when I try without the script works fine. 即使我尝试不使用脚本也能正常工作。
Please help, Thanks in advance, Joe 请帮助,在此先感谢,乔
To supply a password directly in the command line string, you should use mysql --password=[password]
. 要直接在命令行字符串中提供密码,您应该使用mysql --password=[password]
。 See this article . 看到这篇文章 。
And to prompt the user for a password, you should probably use something like this. 为了提示用户输入密码,您可能应该使用类似这样的方式。
#!/bin/bash
read -p "Username: " uname
stty -echo
read -p "Password: " passw; echo
stty echo
You must not ever print the password. 您绝对不能打印密码。 And it should not be seen while typing it in either. 而且在任何一个中键入它时都不应看到它。
#!/bin/bash
read -p "Username: " uname
stty -echo
read -p "Password: " passw; echo
stty echo
mysql --user=$uname --password=$passw
That script works for me. 该脚本对我有用。 If it doesn't for you, please check that your mysql permissions allow you to login from localhost
. 如果不适合您,请检查您的mysql权限是否允许您从localhost
登录。
In a shellscript, you can do 在shellscript中,您可以执行
set -x
to see what the command being executed looks like. 看看正在执行的命令是什么样子。
You should prolly do mysql --password="$mysqlrp". 您应该正确地执行mysql --password =“ $ mysqlrp”。 '$mysqlrp' -> '$mysqlrp'. '$ mysqlrp'->'$ mysqlrp'
In your real script, I suppose you probably want to do 在您的真实脚本中,我想您可能想做
read -p "Password, plz:" -s mysqlrp
In order to properly answer the question, the actual error you get would be helpful. 为了正确回答该问题,您得到的实际错误会有所帮助。 [UPDATE: answered in comment.] [更新:在评论中回答。]
Also, note that if your query is longrunning, your password will be visible in "ps -ef" 另外,请注意,如果查询长时间运行,则密码将在“ ps -ef”中显示
