我试图在Linux上使用MySQL。它之前工作得很好但不知何故我搞砸了。现在每当我输入#mysql时，它只会给我标题中的错误。我对这个话题进行了大量的研究，有人说这是my.cnf的问题。所以我试图在/etc/MySQL/my.cnf中找到该文件。但奇怪的是在我的机器上，文件位于/ usr。而且它不仅位于不同的目录中，其内容也很奇怪。
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
其他一些网站说我应该检查MySQL是否正在运行。每当我输入
/etc/init.d/mysql status
它只是说-bash：/etc/init.d/mysql：没有这样的文件或目录。
经过无数次尝试，我决定重新安装MySQL。我按照this网站上的说明进行操作。但是，当它完成时会出现同样的问题。
我是否在错误的目录中安装MySQL？或者my.cnf有问题吗？有人请帮忙，因为我已经被困在这里超过2周，仍然无法得到线索。
提前谢谢。
