on'的大文件

当我在Ubuntu环境下开发时，我得到了一个警告，说服务器很快就会被淘汰。所以我跟踪了哪个文件在磁盘上占用了太多的空间。而且我能够发现在etc/nginx下面有一个文件名。（我正在使用nginx）

这个文件是做什么的？这个文件占用了7.7G，其types是ASCII文本，很长的行（我通过使用file *命令）

我想通过删除这个文件来pipe理服务器的存储。这样做是否安全？我不能只是不断增加服务器的存储空间。

如果有什么看起来可疑和错误的，任何build议和意见，将不胜感激。

先谢谢你。

这里是nginx.conf

检查存储

找出它是什么types

 /etc/nginx# file * conf.d: directory docker_default: ASCII text, with very long lines Dockerfile: UTF-8 Unicode text fastcgi_params: ASCII text koi-utf: C source, ASCII text koi-win: C source, ASCII text mime.types: ASCII text modules: symbolic link to `/usr/lib/nginx/modules' nginx.conf: ASCII text on: ASCII text, with very long lines scgi_params: ASCII text sites-enabled: directory ssl: directory uwsgi_params: ASCII text win-utf: C source, ASCII text

据我所知，但我可能是错的，不存在这样的指令： access_log on;

我怀疑这个指令让NGinx写访问日志文件on而不是使用access_log /var/log/nginx/access.log;指定的文件access_log /var/log/nginx/access.log;

访问日志可以使用access_log off; ，这是一个现有的指令。

保持访问日志删除access_log on; ，那么它会将日志写入access_log指令中指定的文件中： access_log /var/log/nginx/access.log;
