Install MySQL on Ubuntu without a password prompt
提问by Venkat
How do I write a script to install MySQL server on Ubuntu?
如何编写脚本在 Ubuntu 上安装 MySQL 服务器？
sudo apt-get install mysqlwill install, but it will also ask for a password to be entered in the console.
sudo apt-get install mysql将安装，但它还会要求在控制台中输入密码。
How do I do this in a non-interactive way? That is, write a script that can provide the password?
如何以非交互式方式执行此操作？也就是写个脚本可以提供密码？

sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password password your_password'
sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password your_password'
sudo apt-get -y install mysql-server
For specific versions, such as mysql-server-5.6, you'll need to specify the version in like this:
对于特定版本，例如mysql-server-5.6，您需要像这样指定版本：
sudo debconf-set-selections <<< 'mysql-server-5.6 mysql-server/root_password password your_password'
sudo debconf-set-selections <<< 'mysql-server-5.6 mysql-server/root_password_again password your_password'
sudo apt-get -y install mysql-server-5.6
For mysql-community-server, the keys are slightly different:
对于 mysql-community-server，密钥略有不同：
sudo debconf-set-selections <<< 'mysql-community-server mysql-community-server/root-pass password your_password'
sudo debconf-set-selections <<< 'mysql-community-server mysql-community-server/re-root-pass password your_password'
sudo apt-get -y install mysql-community-server
Replace your_password with the desired root password. (it seems your_password can also be left blank for a blank root password.)
将 your_password 替换为所需的 root 密码。（似乎 your_password 也可以为空白 root 密码留空。）
If your shell doesn't support here-strings(zsh, ksh93and bashsupport them), use:
如果您的 shell 不支持here-strings（zsh、ksh93和bash支持它们），请使用：
echo ... | sudo debconf-set-selections

This should do the trick
这应该可以解决问题
export DEBIAN_FRONTEND=noninteractive
sudo -E apt-get -q -y install mysql-server
Of course, it leaves you with a blank root password - so you'll want to run something like
当然，它会给你一个空白的 root 密码 - 所以你会想要运行类似的东西
mysqladmin -u root password mysecretpasswordgoeshere
Afterwards to add a password to the account.
之后为帐户添加密码。

Another way to make it work:
使其工作的另一种方法：
echo "mysql-server-5.5 mysql-server/root_password password root" | debconf-set-selections
echo "mysql-server-5.5 mysql-server/root_password_again password root" | debconf-set-selections
apt-get -y install mysql-server-5.5
Note that this simply sets the password to "root". I could not get it to set a blank password using simple quotes '', but this solution was sufficient for me.
请注意，这只是将密码设置为“root”。我无法使用简单的引号设置空白密码''，但这个解决方案对我来说已经足够了。
Based on a solution here.
基于这里的解决方案。
