php – Ubuntu WebServer磁盘空间突然增加

NewRelic总是告诉我主空间已经满了.

我检查使用这个空间的是什么：

sudo du -a / var / www |排序-n

但一切看起来都很健康

然后我开始冲洗缓存.

并注意到,当我这样做时：

重置QUERY CACHE;
重置大师;

并重新启动NGINX和PHP5将释放空间.

my.cnf上有任何配置,我错过了???

UPDATE

my.cnf文件：

# MariaDB database server configuration file.
#
# You can copy this file to one of:
# - "/etc/mysql/my.cnf" to set global options,# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
