3)Nginx配置文件(引用jinja模板)
  功能点:
  1、worker_processes参数采用grains['num_cpus'] 上报值(与设备CPU核数一致);
  2、worker_cpu_affinity分配多核CPU根据当前设备核数进行匹配,分别为248其它核;
  3、worker_rlimit_nofile参数与grains['max_open_file'] 获取的系统ulimit -n一致;
  4、worker_connections 参数理论上为grains['max_open_file'];
  5、 root参数为定制的pillar['nginx']['root']值。

  4)同步配置
  #salt '*' state.highstate
  1
  #salt '*' state.highstate
  5)验证结果:
  注意查看root定义值和worker_processes值。
  1、登录root@SN2013-08-021
  #vi /etc/nginx/nginx.conf
  1
  #vi /etc/nginx/nginx.conf
  2、登录root@SN2012-07-010
  #vi /etc/nginx/nginx.conf
  1
  #vi /etc/nginx/nginx.conf
