mysql - 无法为 MySQL "root"用户 : An error occurred while setting the password for the MySQL administrative user 设置密码

Question

最近，我尝试在使用 Ubuntu Trusty 作为基本操作系统镜像的 BOSH Lite 作业容器中安装 mysql-server。

我在作业控制脚本中使用了以下一组 shell 命令。

DB_PASSWORD=root
DB_USERNAME=root

# set and export environment variables
export DEBIAN_FRONTEND=noninteractive
export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

# set MySQL root password configuration using debconf
echo debconf mysql-server/root_password password ${DB_PASSWORD} | \
sudo debconf-set-selections
echo debconf mysql-server/root_password_again password ${DB_PASSWORD} | \
sudo debconf-set-selections

# run package updates
apt-get update

# install mysql
apt-get -y install mysql-server

但是我在安装过程中遇到以下错误。

Configuring mysql-server-5.5
----------------------------

Unable to set password for the MySQL "root" user

An error occurred while setting the password for the MySQL administrative 
user. This may have happened because the account already has a password, or 
because of a communication problem with the MySQL server.

You should check the account's password after the package installation.

Please read the /usr/share/doc/mysql-server-5.5/README.Debian file for more 
information.

与其自行推出，为什么不使用 Pivotal 创建并包含在 CloudFoundry 中的那个:
