mysql 16.04 中保留旧版本

我正在使用 Ubuntu 16.04。目前，我有 MySQL 5.7.31。我需要在笔记本电脑上安装 MySQL 8。我尝试在 Ubuntu 16.04 中安装它。

我没有获得 MySQL 8.0，而是保留了 5.7.31。下一步该怎么做才能获得 MySQL 8.0 版本？

答案1

尝试以下步骤将 MySQL 存储库添加到您的列表并安装 MySQL 8.0。我还没有测试过，但根据文档，它应该可以工作（除非我输入错误）。

将 MySQL GPG 公钥安装到你的 APT 密钥环：（另请参阅这个帖子）

sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 5072E1F5

将 MySQL Xenial Repo 添加到你的 repo 列表中:(根据本指南）

sudo add-apt-repository "deb http://repo.mysql.com/apt/ubuntu/ xenial mysql-8.0"

更新包列表：

sudo apt-get update

安装 MySQL 8.0：

sudo apt-get install mysql-server
