安装MySQL Server 5.7准备工作

我们可以从mysql下载页面下载repository包。

使用wget命令将repo包下载到系统上。

sudo wget http://dev.mysql.com/get/mysql-apt-config_0.6.0-1_all.deb

使用dpkg命令，安装repo deb包。

sudo dpkg -i mysql-apt-config_0.6.0-1_all.deb

安装后，我们将在apt目录中找到新的更改，所以我们也来检查一下。

在安装mysql repo deb包之后，它将在 /etc/apt/sources.list.d/创建一个mysql.list文件。

运行命令cat /etc/apt/sources.list.d/mysql.list我们将在中看到一些mysql repo 地址。

cat /etc/apt/sources.list.d/mysql.list
