pid是nginx的进称号，通过netstat -tnpl可以查到
### Nginx 监控
通过在配置文件中加入：
location ~ ^/status/ {
	    stub_status on; #Nginx 状态监控配置
	    access_log off;
	 }
就可以使用http://yourdomain.com/stauts监控nginx的状态。
可以看到类似这样的信息
Active connections: 70
server accepts handled requests
 14553819 14553819 19239266
Reading: 0 Writing: 3 Waiting: 67

	active connections – 当前 Nginx 正处理的活动连接数.
	server accepts handled requests -- 总共处理了 14553819 个连接 , 成功创建 14553819 次握手 ( 证明中间没有失败的 ), 总共处理了 19239266 个请求 ( 平均每次握手处理了 1.3 个数据请求 )
	reading -- nginx 读取到客户端的 Header 信息数
	writing -- nginx 返回给客户端的 Header 信息数。
	waiting -- 开启 keep-alive 的情况下，这个值等于 active - (reading + writing)，意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接。
