nginx - Many such files are generated in the web server root directory?

Question

I don’t know why, nginx will generate many such files in the web root directory. Does anyone know?

Answer 1

The core file is used for debugging. If you don’t want to generate a core dump file, check these:

Execute ulimit -a | grep 'core file'看看是否为0，如果不为0，代表你打开了调试，可以使用ulimit -c 0 first to close it.

If it is 0, check the nginx.conf configuration file to see if there is this configuration item in it

working_directory  /;
worker_rlimit_core 500M;

If it exists, you can set worker_rlimit_core to 0 and restart the nginx service.

The original core dump file can be deleted if you don’t want it.
