AWS Ubuntu 14.04 上的无人值守 MySQL 安装

Question

我正在尝试执行以下脚本以无人值守方式安装 MySQL。

“export DEBIAN_FRONTEND=noninteractive”不起作用 - 我仍然需要按几次 Enter 才能通过提示。

AWS 映像：Ubuntu Server 14.04 LTS (PV)，SSD 卷类型 - ami-d85e75b0

有什么建议吗？

#!/bin/sh

sudo apt-get install libaio1

export DEBIAN_FRONTEND=noninteractive

# Install script for mysql database

sudo groupadd mysql
sudo useradd -r -g mysql mysql
sudo tar xvf mysql-server_5.6.21-1ubuntu12.04_amd64.deb-bundle.tar
if [ $? != 0 ];then echo "Unable to extract tar file."; exit 100; fi

sudo dpkg -i mysql-common_5.6.21-1ubuntu12.04_amd64.deb
if [ $? != 0 ];then echo "Unable to install package mysql-common."; exit 100; fi

sudo dpkg -i mysql-community-server_5.6.21-1ubuntu12.04_amd64.deb
if [ $? != 0 ];then echo "Unable to install package mysql-community-server."; exit 100; fi

sudo dpkg -i mysql-community-client_5.6.21-1ubuntu12.04_amd64.deb
if [ $? != 0 ];then echo "Unable to install package mysql-community-client."; exit 100; fi

sudo mv /etc/mysql/my.cnf my.cnf.in
if [ $? != 0 ];then echo "Unable to move /etc/mysql/my.cnf."; exit 100; fi

sudo sed -e s/127.0.0.1/0.0.0.0/g my.cnf.in | sudo tee /etc/mysql/my.cnf
if [ $? != 0 ];then echo "Unable to configure my.cnf."; exit 100; fi

#sudo rm -f my.cnf.in

sudo /etc/init.d/mysql restart
if [ $? != 0 ];then echo "Unable to restart mysql server."; exit 100; fi

exit 0

# Leave the last line empty, otherwise it can cause problems running the script

Answer 1

看，在手册man dpkg 中，您可以找到一组选项--force-confdef（强制保留默认选项而不提示）和--force-confold（强制保留旧的conf 文件）

因此，最终命令将如下所示（取决于您需要什么）：
sudo dpkg -i --force-confdef mysql-common_5.6.21-1ubuntu12.04_amd64.deb
或
sudo dpkg -i --force-confold mysql-common_5.6.21-1ubuntu12.04_amd64.deb

试试这个方法，它在issue here 中帮助了我。 顺便问一下，dpkg 在问你什么？

问候我还没有尝试过，但几周前我看到了这个 tut：
