无人值守的phpmyadmin安装最终导致抛出错误

Question

我正试图通过我的Ubuntu12.04LTS上的debconf set-selection命令来安装phpmyadmin预置信息。

这就是我要用的

echo phpmyadmin phpmyadmin/dbconfig-install boolean true | debconf-set-selections
echo phpmyadmin phpmyadmin/app-password-confirm password pwd | debconf-set-selections
echo phpmyadmin phpmyadmin/mysql/admin-pass password pwd| debconf-set-selections
echo phpmyadmin phpmyadmin/mysql/app-pass password pwd| debconf-set-selections
echo phpmyadmin phpmyadmin/reconfigure-webserver multiselect apache2 | debconf-set-selections
echo phpmyadmin phpmyadmin/upgrade-backup boolean true | debconf-set-selections

但我总是收到以下错误消息

error: Cannot find a question for phpmyadmin/dbconfig-install
error: Cannot find a question for phpmyadmin/app-password-confirm
error: Cannot find a question for phpmyadmin/mysql/admin-pass
error: Cannot find a question for phpmyadmin/mysql/app-pass
error: Cannot find a question for phpmyadmin/upgrade-backup

如果我尝试使用shell中的sudo运行命令，则会收到以下消息

debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied

然而，我曾经能够安装这个。那么是什么原因呢？

Answer 1

这可能与debconf bug：http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487300有关。

你的数据库可能被破坏了。

运行/usr/share/debconf/fix_db.pl可以修复它。

我希望它对你有用。

Answer 2

运行：sudo /usr/share/debconf/fix_db.pl可以修复它。

请记住安装mysql服务器，因为您需要连接到套接字。无人看管的还有：

echo "mysql-server mysql-server/root_password password root" | sudo debconf-set-selections
echo "mysql-server mysql-server/root_password_again password root" | sudo debconf-set-selections

apt-get install mysql-client mysql-server -y

使用高权限，最终安装将是：

echo 'phpmyadmin phpmyadmin/dbconfig-install boolean true' | sudo debconf-set-selections
echo 'phpmyadmin phpmyadmin/app-password-confirm password root' | sudo debconf-set-selections
echo 'phpmyadmin phpmyadmin/mysql/admin-pass password root' | sudo debconf-set-selections
echo 'phpmyadmin phpmyadmin/mysql/app-pass password root' | sudo debconf-set-selections
echo 'phpmyadmin phpmyadmin/reconfigure-webserver multiselect apache2' | sudo debconf-set-selections
sudo apt-get install phpmyadmin -y

这样，一切都很顺利。

当有疑问的时候，加入更多的sudos .这就是我的无人值守的MySQL安装所起的作用：

sudo echo "mysql-community-server mysql-community-server/root-pass password ${DB_PASSWORD_ROOT}" | sudo debconf-set-selections

与OP一样，我的脚本在没有任何sudo前缀的情况下作为根用户运行良好。所以我不知道为什么在某些情况或环境中这很重要：

顺便说一句，感谢那些分享这段片段的人：

sudo /usr/share/debconf/fix_db.pl ...如果没有其他的有趣的话！
