mysql - 无法在 ubuntu 21.04 上运行 mysql

Question

我很难在 ubuntu 21.04 上运行 mysql。我试过了：

sudo apt remove --purge mysql-server
sudo apt purge mysql-server
sudo apt autoremove
sudo apt autoclean
sudo apt remove dbconfig-mysql

和

sudo systemctl stop mysql
sudo apt purge mysql-server mysql-client mysql-common mysql-server-core-* mysql-client-core-*
sudo rm -rf /etc/mysql /var/lib/mysql /var/log/mysql
sudo apt autoremove
sudo apt autoclean

在重新安装 mysql-server 之前：

sudo apt update
sudo apt install mysql-server

但无济于事。问题是，当我安装时，我在终端中得到了这个：

Errors were encountered while processing:
 mysql-server-8.0
 mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

当我运行时sudo mysql，我收到此错误：

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

当我跑步时，systemctl status mysql我得到：

mysql.service - MySQL Community Server
     Loaded: error (Reason: Unit mysql.service failed to load properly: Device or resource busy.)
     Active: failed (Result: exit-code) since Sun 2021-09-05 23:29:27 EET; 58min ago
   Main PID: 31191 (code=exited, status=1/FAILURE)
     Status: "Server startup in progress"

我试过了：

sudo systemctl stop  mysql
sudo systemctl start  mysql

但我明白了

Failed to start mysql.service: Unit mysql.service failed to load properly: Device or resource busy.
See system logs and 'systemctl status mysql.service' for details.

在 error.log 我得到：

2021-09-05T22:26:37.674376Z 0 [错误] [MY-010262] [服务器] 无法启动服务器：在 TCP/IP 端口上绑定：地址已在使用中

2021-09-05T22:26:37.674517Z 0 [错误] [MY-010257] [服务器] 您是否已经在端口：3306 上运行了另一个 mysqld 服务器？

2021-09-05T22:26:37.674808Z 0 [错误] [MY-010119] [服务器] 中止

但是当我运行时，netstat -lp | grep 3306我发现端口 3306 上没有运行任何东西。我通过运行来保证 sudo kill -9 $(sudo lsof -t -i:3306)

关于如何解决这个问题的任何想法？
