nginx报错:socket() failed (24: Too many open files) while connecting to upstream-下一朵云

nginx反代新项目,在线人数过多时就会报错,查看日志,报错如下:

socket() failed (24: Too many open files) while connecting to upstream

决办法

1.修改linux打开文件句柄数,编辑/etc/security/limits.conf,添加

* soft nofile 204800 * hard nofile 204800

2.修改nginx打开文件数, 编辑nginx.conf,添加worker_rlimit_nofile值

worker_processes 1; worker_rlimit_nofile 20480;

3.重启nginx后解决

./nginx -s stop ./nginx
