supervisord引发的打开文件太多？

Question

我在ubuntu 16.04上使用wrk测试由supervisor管理的web API服务。我有错误“太多打开的文件”，但我已经设置了系统配置

/etc/security/limits.conf
*           soft    nofile  65535
*           hard    nofile  65535

仍然有错误“打开的文件太多”

我发现supervisord属于root和cat /proc/PID/limits

Max open files            1024                 4096                 files

因此，将根限制设置添加到limits.conf，如下所示

root        soft    nofile  65535
root        hard    nofile  65535

重新启动supervisord后，它会生效(cat /proc/PID/limits，got为65535)，但supervisord很快就会退出，并自动启动，限制为1024.

Answer 1

我被sudo supervisorctl shutdown解决了不应该直接杀死P
