我整理了一份nginx的配置文件说明,是真正经历过正式线上考验过。如果有优化的地方,也请朋友们指点一二,整理出一份比较全而实用的配置。

主要包含配置:负载均衡配置,页面重定向,转发,HTTPS和HTTP的配置, 缓存优化,错误页面配置等。

#工作进程,于CPU核数一致
worker_processes  2;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events 
    # 设置可连接数
    worker_connections  2048;
    #优化同一时刻只有一个请求而避免多个睡眠进程被唤醒的设置,on为防止被同时唤醒,默认为off,因此nginx刚安装完以后要进行适当的优化。
    accept_mutex on;
    #打开同时接受多个新网络连接请求的功能
    multi_accept on;

后续也会继续完善此配置,大家在配置的时候,基本上可以满足应用了。。。
