user是个主模块指令，指定Nginx Worker进程运行用户以及用户组，默认由nobody账号运行。
worker_processes:主模块指令，指定了Nginx要开启的进程数。每个Nginx进程平均耗费10M~12M内存。建议指定和CPU的数量一致即可。
error_log:主模块指令，用来定义全局错误日志文件。日志输出级别有debug、info、notice、warn、error、crit可供选择，其中，debug输出日志最为最详细，而crit输出日志最少。
pid是个主模块指令，用来指定进程pid的存储文件位置。
worker_rlimit_nofile用于绑定worker进程和CPU， Linux内核2.4以上可用。
events事件指令是设定Nginx的工作模式及连接数上限：
#user nobody; worker_processes 1; //
#error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info;
#pid logs/nginx.pid;
events { worker_connections 1024; }
