　　Active connections: 1     
　　##nginx正处理的活跃连接数
　　
　　server accepts handled requests
　　##server  nginx启动到现在共处理了多少个连接
　　##accepts  nginx启动到现在共创建了多少次握手，请求丢失数=握手数-连接数
　　##handled requests    总共处理了多少个请求
　　Reading: 0 Writing: 1 Waiting: 0
　　##Reading  nginx读取客户端 header 信息数
　　##Writing  nginx返回给客户端的 hearder 信息数
　　##Waiting  nginx已经处理完正在等待下一次请求指令的驻留连接，在开启keep-alive的情况下，waiting值等于active - (Reading+Writing)
