nginx打开文件过多
军哥，我使用lnmp一键部署了一个网站，运行几天就会报：Too many open files in system。keepalive设置的是60，查看打开文件数：php-fpm这个进程一共创建了5个，打开的文件句柄之和超过了文件句柄上线。
nginx不会自动关闭http连接吗？ 那边出现的这个错误？ nginx后台出现的 ulimit -Hn
ulimit -Sn
cat /etc/security/limits.conf
看一下
open files默认设置上都已经很大了 已经设置为65535了如下所示。
问题是为什么nginx不回收呢，这样再大的设置都有用尽的时候。
一开始安装的时候默认是1024，我跑了1天就无法访问了，然后我设置成了65535，结果跑了十几天又出现了。。。
# ulimit -Hn
65535
# ulimit -Sn
65535
# cat /etc/security/limits.conf
# /etc/security/limits.conf
#
#This file sets the resource limits for the users logged in via PAM.
#It does not affect resource limits of the system services.
#
#Also note that configuration files in /etc/security/limits.d directory,
#which are read in alphabetical order, override the settings in this
#file in case the domain is the same or more specific.
#That means for example that setting a limit for wildcard domain here
#can be overriden with a wildcard setting in a config file in the
#subdirectory, but a user specific setting here can be overriden only
#with a user specific setting in the subdirectory.
#
#Each line describes a limit for a user in the form:
#
#<domain> <type><item><value>
#
#Where:
#<domain> can be:
# - a user name
# - a group name, with @group syntax
# - the wildcard *, for default entry
# - the wildcard %, can be also used with %group syntax,
# for maxlogin limit
#
#<type> can have the two values:
# - "soft" for enforcing the soft limits
# - "hard" for enforcing hard limits
#
#<item> can be one of the following:
# - core - limits the core file size (KB)
# - data - max data size (KB)
# - fsize - maximum filesize (KB)
# - memlock - max locked-in-memory address space (KB)
# - nofile - max number of open file descriptors
# - rss - max resident set size (KB)
# - stack - max stack size (KB)
# - cpu - max CPU time (MIN)
# - nproc - max number of processes
# - as - address space limit (KB)
# - maxlogins - max number of logins for this user
# - maxsyslogins - max number of logins on the system
# - priority - the priority to run user process with
# - locks - max number of file locks the user can hold
# - sigpending - max number of pending signals
# - msgqueue - max memory used by POSIX message queues (bytes)
# - nice - max nice priority allowed to raise to values: [-20, 19]
# - rtprio - max realtime priority
#
#<domain> <type><item> <value>
#
#* soft core 0
#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0
#@student - maxlogins 4
# End of file
* soft nproc 65535
* hard nproc 65535
* soft nofile 65535
* hard nofile 65535

nginx不回收不清楚回复 6# 的帖子
我跟踪了一下，是因为php-fpm占用的文件句柄太多。每次访问，它都打开一个php文件，从来不会释放。最终导致句柄耗尽。军哥，这么配置php-fpm，让其定期清理文件句柄吗？回复 7# 的帖子
不清楚句柄清理php打开了文件没有进行关闭占用了的的话应该在php上进行关闭就可以了吧，php菜鸟
