•  nginx经常使用命令

nginx  -t  ##检查配置文件，通常修改完配置文件都建议必定先执行这条命令检查一下，无误再继续下一步
nginx –s reload   ##从新加载配置文件，动态加载使你能够不用重启nginx

nginx -s reopen            # 重启 Nginx

nginx -s stop              # 中止 Nginx

•  nginx配置

咱们能够打开nginx的配置文件 nginx.conf 先看看

#user  nobody;   #Nginx用户及组：用户 组。window下不指定
worker_processes  1;    #工做进程：数目。根据硬件调整，一般等于CPU数量或者2倍于CPU。

#错误日志：存放路径。
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events模块配置：

 events事件指令是设定Nginx的工做模式及链接数上限。每一个配置选项的含义解释以下：
a、use
如：use epoll;
use是事件模块指令，用来指定Nginx的工做模式。Nginx支持的工做模式有select、poll、kqueue、epoll、rtsig和/dev/poll 。其中select 和poll 都是标准的工做模式，kqueue和epoll是高效的工做模式，不一样的是epoll用在Linux平台上，而kqueue用在BSD系统中。对于Linux系统，epoll工做模式是首选。

b、worker_connections
如：worker_connections65536;
work_connections也是个事件模块指令，用于定义Nginx每一个进程的最大链接数，默认是1024。
