我在Ubuntu 12.04上使用mysql时遇到了一些麻烦。我希望这篇文章在正确的论坛上（如果没有，请告诉我在哪里移动它）
当我运行：sudo /etc/init.d/mysql时，我收到此消息
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start mysql
start: Job failed to start
当我运行mysql -u root status时，我得到了这个
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
所以我试图杀死这个过程，所以我运行了ps aux | grep mysql显示这个
1000 3262 0.0 0.0 4388 832 pts/1 S+ 14:05 0:00 grep --color=auto mysqld
当我运行kill命令时，我得到了这个：
kill：没有这样的过程
当我启动sudo mysqld --verbose
时[Warning] The syntax '--log-slow-queries' is deprecated and will be removed in a future release. Please use '--slow-query-log'/'--slow-query-log-file' instead.

有人可以帮忙吗

使用命令“mysql”，您要做的是启动mysql客户端。 Mysql客户端必须连接到服务器。 您应该像Jeremy建议的那样启动mysql服务器，或者使用
sudo start mysql
