如何在Ubuntu 20.04上安装Mysql 5.7.30

我正在 Ubuntu 20.04 上安装 MySQL 5.7.30。当我跑步时：

sudo dpkg -i mysql-apt-config_0.8.16-1_all.deb

这是输出：

(Reading database ... 74194 files and directories currently installed.)
Preparing to unpack mysql-apt-config_0.8.16-1_all.deb ...
Unpacking mysql-apt-config (0.8.16-1) over (0.8.16-1) ...
Setting up mysql-apt-config (0.8.16-1) ...
Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package mysql-apt-config)
OK

任何人都可以解释如何避免此警告及其含义吗？我现在很困惑。

mysql存储库中的版本mysql从 升级到5.7.30。它可以从存储库5.7.33安装。focalbionic

您可以使用它sudo dpkg-reconfigure mysql-apt-config来设置存储库。

您也可以手动编辑您的内容，/etc/apt/sources.list.d/mysql.list如下所示：

deb http://repo.mysql.com/apt/ubuntu/ bionic mysql-apt-config
deb http://repo.mysql.com/apt/ubuntu/ bionic mysql-5.7
deb http://repo.mysql.com/apt/ubuntu/ bionic mysql-tools
deb http://repo.mysql.com/apt/ubuntu/ bionic mysql-tools-preview
deb-src http://repo.mysql.com/apt/ubuntu/ bionic mysql-5.7

如果你还没有添加 gpg key ，你可以查看官方文档来验证并添加 mysql gpg ： 2.1.4.2 使用 GnuPG 检查签名

为了防止mysql-apt-config覆盖mysql.list, it can be removed.

然后运行：

sudo apt update
apt policy mysql-server

示例输出：

mysql-server:
  Installed: (none)
