[v_act]环境说明：[/v_act]
1、系统：CentOS最小化安装；升级软件补丁，内核和系统版本不升级；关闭SELinux和防火墙。系统安装可参考[neilian ids=595]2、软件：安装包统一放置在/usr/src目录下，安装位置统一在/usr/local目录下。
[v_act]开始安装：[/v_act]
1、安装Nginx所需pcre库，官方网站（www.pcre.org）。安装pcre库是为了使Nginx支持具备URL重写功能的Rewite模块，如不安装则Nginx无法使用此模块功能（典型功能为伪静态）。

LISTEN 0 128 *:80 *:*[v_act]Web访问验证[/v_act]
[v_act]调整参数[/v_act]
1、当我们安装完Nginx程序后首先有几个参数需要调整下，需要调整的参数为user、worker_processes、worker_connections；Nginx主配置文件位于/usr/local/nginx/conf目录下的nginx.conf
[root@localhost conf]# vim nginx.conf
user www www; #指定运行Worker进程的用户和组，根据编译安装时指定的用户及组修改，默认为nobody；例如：user www www;
worker_processes auto; #常规调优选项 Worker线程的个数；通常应该为物理CPU核心个数减1；自动为auto
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 51200; #常规调优选项 设定单个Worker进程所能够处理响应的最大并发请求数（worker_connections * worker_processes）；默认为1024，建议为51200，最大为65535。
}2、调整参数后验证配置文件是否有误
[root@localhost conf]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx-1.12.2/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx-1.12.2/conf/nginx.conf test is successful3、重新加载配置文件或重启系统均可
[root@localhost conf]# /usr/local/nginx/sbin/nginx -s reload正文完
