我在启动mysql服务时遇到了问题,所以我删除了如下程序包:

sudo dpkg -P mysql-server mysql-server-5.7
sudo apt autoremove
sudo apt clean
sudo rm -rvf /var/lib/mysql
sudo apt install mysql-server

在安装过程中,我被要求输入root的密码,然后发生了以下情况:

Setting up mysql-server-5.7 (5.7.21-0ubuntu0.16.04.1) ...
Renaming removed key_buffer and myisam-recover options (if present)

跑步 dpkg --configure -a 导致同样的错误。这里是 journalctl -xe :

其他人似乎也有同样的问题,但迄今为止我发现的解决方案都不管用。例如,有人说他们的问题是由一个丢失的日志文件引起的,这个文件对我来说不是丢失的。

感谢迈克尔o。至于评论,它帮了我很大的忙。他自己链接的问题的答案并没有解决我的问题,因为在将mysql列入白名单以访问它需要的文件之后,apparmor开始阻止mysql获取功能。
在搜索时,我看到了一篇来自oracle的博客文章,其中建议使用 apparmor-utils 的实用程序调用 aa-complain . 这个实用程序设置一个配置文件到投诉模式,基本上让你一个警告。
所以我安装了 apparmor-utils :

sudo apt install apparmor-utils

已检查mysql服务的位置:

which mysql

并使用输出将服务置于投诉模式:

aa-complain /usr/bin/mysql

重新启动计算机后,服务将正常启动。
