如何设置nginx max打开文件? [英] How to set nginx max open files?
问题描述
尽管我已经完成了以下设置,甚至重启了服务器:
Though I have done the following setting, and even restarted the server:
# 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然是1024/4096:
The open files limitation of specific process is still 1024/4096:
# ps aux | grep nginx
root 983 0.0 0.0 85872 1348 ? Ss 15:42 0:00 nginx: master process /usr/sbin/nginx
www-data 984 0.0 0.2 89780 6000 ? S 15:42 0:00 nginx: worker process
www-data 985 0.0 0.2 89780 5472 ? S 15:42 0:00 nginx: worker process
root 1247 0.0 0.0 11744 916 pts/0 S+ 15:47 0:00 grep --color=auto nginx
# cat /proc/984/limits

我尝试了从谷歌搜索到的所有可能解决方案,但徒劳无功.我错过了什么设置?
I've tried all possible solutions from googling but in vain. What setting did I miss?
推荐答案
在CentOS上(在7.x上测试):
使用以下内容创建文件/etc/systemd/system/nginx.service.d/override.conf
:
Create file /etc/systemd/system/nginx.service.d/override.conf
with the following contents:
[Service]
LimitNOFILE=65536
使用以下命令重新加载systemd守护程序:
Reload systemd daemon with:
systemctl daemon-reload
将此添加到Nginx配置文件中:
Add this to Nginx config file:
worker_rlimit_nofile 16384; (has to be smaller or equal to LimitNOFILE set above)
最后重新启动Nginx:
And finally restart Nginx:
systemctl restart nginx
您可以验证它是否可以与cat /proc/<nginx-pid>/limits
一起使用.
You can verify that it works with cat /proc/<nginx-pid>/limits
.
