nginx accept() failed (24: Too many open files)

nginx服务器出现如下信息：

[crit] 17221#0: accept4() failed (24: Too many open files)
[crit] 17221#0: accept4() failed (24: Too many open files)
[crit] 17221#0: accept4() failed (24: Too many open files)
[crit] 17221#0: accept4() failed (24: Too many open files)
[crit] 17221#0: accept4() failed (24: Too many open files)

原回是nginx进程打开文件数过多

 

解决方法：

修改/etc/security/limits.conf文件

* soft nofile 10240
* hard nofile 10240

星号代表全局，soft为软件，hard为硬件，nofile为这里指可打开文件数。

root soft nofile 10240
root hard nofile 10240
nobody soft nofile 10240
nobody hard nofile 10240

修改nginx.conf，添加如下代码：

worker_rlimit_nofile 10240;

重启nginx服务器。
