nignx.conf配置说明

#一般使用创建的nginx用户组，避免使用root用户，防止被黑直接有root权限
user www www;
#一般根据cpu数量来，可以使用lscpu查看 CPU(s): 4，当然可以直接写auto自动获取
worker_processes auto;
# debug|info|notice|warn|error|crit 初始使用crit级别就行，当有比较多502信息时可以调成error或其他等级分析日志
error_log /home/wwwlogs/nginx_error.log crit;
#将 PID 输出到 /xxx/nginx.pid 文件中；
pid /usr/local/nginx/logs/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
#指定此进程可以打开的最大文件描述符的值。
#同时连接的数量受限于系统上可用的文件描述符的数量 可用 ulimit -n 查看（比如我的2C4G测试机返回 1048576）
#如果NGINX尝试打开比可用文件描述符更多的套接字，会发现error.log中出现Too many opened files的信息
worker_rlimit_nofile 51200;
events
{
use epoll;
#每个 Nginx 工作进程最大连接数（线程数）生产环境最好 > 9000
#根据系统的最大打开文件数来调整
#系统的最大打开文件数>= worker_connections*worker_process
#查看系统的最大打开文件数： ulimit -a | grep "open files"
#如返回 open files (-n) 1048576
#若此值过小（如一些1024的默认）需要修改系统变量并重启 （一般该到65535）
#参考：https://blog.csdn.net/weixin_60766221/article/details/127462231
worker_connections 51200;
#让NGINX worker能够在获得新连接的通知时尽可能多的接受连接，立即接受所有连接放到监听队列中，否则将逐个接受连接
