Jia*_*ang 16 linux ubuntu nginx limit
虽然我已经完成了以下设置,甚至重新启动了服务器:
# head /etc/security/limits.conf -n2
www-data soft nofile -1
www-data hard nofile -1
# /sbin/sysctl fs.file-max
fs.file-max = 201558

特定进程的打开文件限制仍为1024/4096:

我已经通过谷歌搜索尝试了所有可能的解决方案但是徒劳无功.我错过了什么设置?

在CentOS上(在7.x上测试):
/etc/systemd/system/nginx.service.d/override.conf使用以下内容创建文件:
[Service]
LimitNOFILE=65536

使用以下命令重新加载systemd守护程序:
systemctl daemon-reload

将此添加到Nginx配置文件:
worker_rlimit_nofile 16384; (has to be smaller or equal to LimitNOFILE set above)

最后重启Nginx:
systemctl restart nginx

您可以验证它是否有效cat /proc/<nginx-pid>/limits.

在发布此问题后的几分钟内我找到了答案......
# cat /etc/default/nginx
# Note: You may want to look at the following page before setting the ULIMIT.
# http://wiki.nginx.org/CoreModule#worker_rlimit_nofile
# Set the ulimit variable if you need defaults to change.
# Example: ULIMIT="-n 4096"
ULIMIT="-n 15000"

/etc/security/limit.conf由PAM使用,因此它与www-data(它是nologin用户)无关.
对于 nginx,只需编辑nginx.conf和设置即可worker_rlimit_nofile更改限制。我最初认为这是 nginx 的自我限制,但它增加了每个进程的限制:
worker_rlimit_nofile 4096;

您可以通过获取 nginx 进程 ID(来自top -u nginx)进行测试,然后运行:
cat /proc/{PID}/limits

CentOS 7 上的另一种方法是通过systemctl edit SERVICE_NAME,在那里添加变量:
[Service]
LimitNOFILE=65536

保存该文件并重新加载服务。
