出于好奇，我想看看 Ubuntu 14.04 上的 MySQL 5.6。根据这篇文章，安装看起来应该简单明了。所以我启动了一个运行 Ubuntu 14.04（64 位）的 AWS EC2 微型服务器，登录到我的原始实例（通过 PuTTY），并发出以下命令：
$ sudo apt-get update
$ sudo apt-get build-dep mysql-server-5.6
$ sudo apt-get install mysql-server-5.6
（前两个命令是绝望的举动，因为apt-get install以前单独运行是行不通的。但即使使用了所有三个命令，安装步骤仍然不起作用。）
在我期望的地方，根据上面引用的文章，可以看到最终命令的输出：
mysql start/running, process 2355
Setting up libhtml-template-perl (2.95-1) ...
Setting up mysql-common-5.6 (5.6.16-1~exp1) ...
Processing triggers for libc-bin (2.19-0ubuntu6) ...
Processing triggers for ureadahead (0.100.0-16) ...
我得到了这个：
start: Job failed to start
invoke-rc.d: initscript mysql, action "start" failed.
dpkg: error processing package mysql-server-5.6 (--configure):
subprocess installed …这个问题真的很奇怪，我尝试了很多方法来解决但没有任何效果。我的最后输出是：
