服务器是Ubuntu 13.04(GNU / Linux 3.9.3-x86_64-linode33 x86_64)。
nginx是nginx / 1.2.6。
我已经为此工作了几个小时,所以这就是我得到的,这也是我所做的。

Nginx运行:
geuis@localhost:~$ ps aux | grep nginx
root 3422 0.0 0.0 39292 380 ? Ss 21:30 0:00 nginx: master process /usr/local/nginx/sbin/nginx

在/etc/security/limits.conf中修改的软/硬限制(从文件末尾开始设置)
root soft nofile 65536
root hard nofile 65536
www-data soft nofile 65536
www-data hard nofile 65536
nobody soft nofile 65536
nobody hard nofile 65536
阅读最大文件
cat /proc/sys/fs/file-max
500000
在/etc/pam.d/common-session中:
session required pam_limits.so
添加了此选项,并很好地重启了服务器,对于Nginx,我通过获取父进程的PID来计算软限制/硬限制,并:
cat /proc/<PID>/limits
Limit Soft Limit Hard Limit Units
Max open files 1024 4096 files
父进程以“ root”身份运行,而4个工人以“ nobody”身份运行。

我已经尝试了一切我知道该怎么做的方法,并且能够从Google获得。我无法增加Nginx的文件限制。
救命?
worker_rlimit_nofile
uWSGI设置而不是系统限制(这对我有用),则无法通过进行验证ulimit
。相反,您应该直接查看/proc/<pid of worker>/limits
。
