配置 Nginx
先来看一个实际的配置文件：
user nobody;# 工作进程的属主
worker_processes 4;# 工作进程数，一般与 CPU 核数等同

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
use epoll;#Linux 下性能最好的 event 模式
worker_connections 2048;# 每个工作进程允许最大的同时连接数
}

http {
include mime.types;
default_type application/octet-stream;

#log_format main '$remote_addr - $remote_user [$time_local] $request '
# '"$status" $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log off;
access_log logs/access.log;# 日志文件名

sendfile on;
#tcp_nopush on;
tcp_nodelay on;

keepalive_timeout 65;

include gzip.conf;

# 集群中的所有后台服务器的配置信息
