Question

我没有设法在乌班图上完全安装mysql...

我在安装mysql时遇到了一个奇怪的问题！

当我在Ubuntu终端中输入这个命令时，我在安装mysql时遇到了以下错误:

sudo apt install mysql-server

当然，在此之前，我用下面的命令彻底删除了一次mysql:

sudo apt-get remove --purge mysql*

和

sudo apt-get purge mysql*

和

sudo apt-get remove dbconfig-mysql

导入这些命令后，我决定从第一个开始再次安装mysql，因此我输入了以下命令：

sudo apt-get install mysql-server

然后，我在终端内看到以下错误消息：

此MySQL安装已升级到5.7.27，如果您仍需要运行mysql.service的mysql_upgrade作业，请使用- force，因为控制进程已退出，错误代码为。详见“systemctl status mysql.service”和“journalctl -xe”。invoke-rc.d: initscript mysql，操作“开始”失败
