mysql-服务器无法安装在 linux

Question

我像那样删除了当前的 mysql :

apt-get remove --purge mysql-server mysql-client mysql-common
apt-get remove --purge mysql-client-core-5.5
apt-get autoremove
apt-get autoclean
rm -rf /var/lib/mysql

当我想重新安装时遇到了一些问题：

apt-get install mysql-server

//输出为

The following packages have unmet dependencies:
 mysql-server : Depends: mysql-server-5.5 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.**

再一次

apt-get install mysql-server-5.5

//输出为

以下信息可能有助于解决问题：

The following packages have unmet dependencies:
mysql-server-5.5 : PreDepends: mysql-common (>= 5.5.47-0+deb7u1) but it is not going to be installed
Depends: mysql-client-5.5 (>= 5.5.47-0+deb7u1) but it is not going to be installed
Recommends: mailx
E: Unable to correct problems, you have held broken packages.

我已经安装了很多次mysql-common和mysql-clint-5.5

可能是什么问题？

Answer 1

我在 6 小时后解决了这个问题 :) 主要问题是版本 number.After unistalling 你应该这样写：

安装mysql-服务器：

首先安装mysql-server-5.5

并安装 mysql-server-5.5:

安装mysql-普通apt-get install mysql-common=5.5.47-0+deb7u1

安装mysql-client-5.5apt-get install mysql-client=5.5.47-0+deb7u1

安装后：安装 mysql-server-5.5 apt-get install mysql-server-5.5

最后：安装 mysql-服务器 mysql-客户端 apt-get install mysql-server mysql-client

Answer 2

我在 ubuntu 20.04 中编写了这个脚本来解决此类问题，请参阅我的评论中的详细信息：

#!/bin/bash

#Force install of missing deps
sudo apt-get -f install -o Dpkg::Options::="--force-overwrite"

#Remove the installed Apache 2
sudo apt-get purge apache2\*

#And followed by:
sudo apt-get purge mysql\*
sudo rm -rf /var/lib/mysql
sudo rm -rf /etc/mysql
sudo dpkg -l | grep -i mysql
sudo apt-get clean
sudo apt-get aut
sudo updatedb

#Reinstall full webstack if you want to.
sudo apt-get install lamp-server^
