Ubuntu 上 nginx 的大型文件“etc/nginx/on”

2024-5-31 • tag-icon

当我在 Ubuntu 环境下进行开发时，我收到一条警告，说服务器的存储空间即将用完。于是我追踪了哪个文件占用了这么多磁盘空间。我发现on下面有一个名为的文件etc/nginx。（我使用的是 nginx ）

这个文件是干什么的？这个文件占用了 7.7G，类型是 ASCII 文本，行数非常长（我用file *命令搞清楚了）

我想通过删除此文件来管理服务器的存储。这样做安全吗？我不能一直增加服务器的存储空间。

如果发现任何可疑或错误，我们将非常感激任何建议和意见。

先感谢您。

这是 nginx.conf

答案1

据我所知，但我可能错了，不存在这样的指令：access_log on;

我怀疑该指令使 NGinx 写入访问日志文件，on而不是你使用指定的文件access_log /var/log/nginx/access.log;

可以使用access_log off;现有指令来禁用访问日志。

要保持访问日志删除，它会将日志写入您的指令access_log on;中指定的文件中：access_logaccess_log /var/log/nginx/access.log;
