Nginx 性能调优 方案

#设置用户的权限  root nobody 指定 用户名虚拟机内用户   或者 Ip访问 
#user  nobody;
#设置工作进程数 一般为 Cpu 核心*2  4*2 
worker_processes  8;  
# 日志输出参数 
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
# 进程ID 
#pid        logs/nginx.pid;

#指定运行模型 
    use epoll;
# 工作连接数  默认512 根据自己的情况调整 
    worker_connections  1024;
}

#http模块 
http {
#  能够支持的类型 在 这个文件下写着  mime.types
    include       mime.types;
# 默认的类型  在 application/octet-stream;

# 日志的格式 
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
