我尝试使用 Synaptic 安装 MySQL，但更新时无法启动，输出如下：

我不知道如何分解初始化失败的地方，或者如何开始它。我是否可能在某个地方缺少一个可以解释此问题的图书馆？禁用的“FEDERATED”插件有关系吗？ InnoDB到底发生了什么？
答案1
你有MySQL服务器，还是只有客户端？这服务器是你应该开始的。检查一下你是否有那个。
$ sudo apt-get install mariadb-server
然后运行：
$ sudo service mariadb start Redirecting to /bin/systemctl start mariadb.service
请注意，mariadb 本质上是 MySQL。另外，发布您正在使用的命令，而不仅仅是输出。另外，我使用的是 CentOS，所以我的输出可能与你的不同。
