1）、创建Nginx 运行使用的用户
　　　　　/usr/sbin/groupadd www
　　　　　/usr/sbin/useradd-g www www
　　2）、配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容　　　

user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
