dump conf from running nginx process
提问by est
Is it possible to get which conf the nginx is using only from a running nginx process?
是否可以仅从正在运行的 nginx 进程中获取 nginx 正在使用的配置？
To get the conf file path. sometimes ps auxreveal it, sometimes it doesn't. It might be just something like nginx: master process /usr/sbin/nginx(same as /proc/PID/cmdline)
获取conf文件路径。有时ps aux显露，有时不显露。它可能只是类似nginx: master process /usr/sbin/nginx（相同于/proc/PID/cmdline）
- So is
nginx -Vthe only solution? - From this question, is it possible to dump conf data structure from nginx process directly? Or at least dump the conf file path?
- 那么是
nginx -V唯一的解决方案吗？ - 从这个问题，是否可以直接从 nginx 进程转储 conf 数据结构？或者至少转储conf文件路径？

As of Nginx 1.9.2 you can dump the Nginx config with the -Tflag:
从 Nginx 1.9.2 开始，您可以使用以下-T标志转储 Nginx 配置：
-T— same as-t, but additionally dump configuration files to standard output (1.9.2).
-T— 与 相同-t，但另外将配置文件转储到标准输出 (1.9.2)。

This is not the same as dumping for a specific process. If your Nginx is using a different config file, check the output for ps auxand use whatever it gives as the binary, e.g. if it gives something like
这与特定进程的转储不同。如果您的 Nginx 使用不同的配置文件，请检查输出ps aux并使用它作为二进制文件提供的任何内容，例如，如果它提供类似
nginx: master process /usr/sbin/nginx -c /some/other/config
you need to run
你需要跑
/usr/sbin/nginx -c /some/other/config -T
If you are not on 1.9.2 yet, you can dump the config with gdb:
如果您还没有使用 1.9.2，您可以使用 gdb 转储配置：
