Linux中的守护程序日志记录 [英] Daemon logging in Linux

问题描述

因此，我有一个在Linux系统上运行的守护程序，我想要记录其活动:日志.问题是，完成此任务的最佳"方法是什么?

So I have a daemon running on a Linux system, and I want to have a record of its activities: a log. The question is, what is the "best" way to accomplish this?

我的第一个想法是简单地打开一个文件并将其写入.

My first idea is to simply open a file and write to it.

FILE* log = fopen("logfile.log", "w");
/* daemon works...needs to write to log */
fprintf(log, "foo%s\n", (char*)bar);
/* ...all done, close the file */
fclose(log);

以这种方式记录是否有天生的错误?有没有更好的方法，例如Linux内置的某些框架?

Is there anything inherently wrong with logging this way? Is there a better way, such as some framework built into Linux?

推荐答案

Unix长期以来一直使用一种名为系统日志.输入您的外壳程序

Unix has had for a long while a special logging framework called syslog. Type in your shell

man 3 syslog

，您将获得C接口的帮助.

and you'll get the help for the C interface to it.
