 proxy更新日志
+v4.0
+1.内网穿透三端重构了一个multiplexing版本，使用github.com/xtaci/smux实现了tcp链接的多路复用，
+  鼎鼎大名的kcp-go底层就是使用的这个库，基于kcp-go的双边加速工具kcptun的广泛使用已经很好
+  的验证来该库的强大与稳定。multiplexing版的内网穿透对应的子命令分别是server，client，bridge
+  使用方式和参数与之前的子命令tserver，tclient，tserver完全一样，另外server，client增加了
+  压缩传输参数--c，使用压缩传输速度更快。
+
+v3.9
+1.增加了守护运行参数--forever,比如: proxy http --forever ,
+  proxy会fork子进程,然后监控子进程,如果子进程异常退出,5秒后重启子进程.
+  该参数配合后台运行参数--daemon和日志参数--log,可以保障proxy一直在后台执行不会因为意外退出,
+  而且可以通过日志文件看到proxy的输出日志内容.
+  比如: proxy http -p ":9090" --forever --log proxy.log --daemon
+
+v3.8
+1.增加了日志输出到文件--log参数,比如: --log proxy.log,日志就会输出到proxy.log方便排除问题.
+
+v3.7
+1.修复了socks代理不能正常和上级代理通讯的问题.
+
+
+v3.6
+1.http(s),socks代理,集成了外部HTTP API认证,可以通过外部API对用户名和密码进行认证.
+2.手册http(s),socks代理认证部分增加了集成外部HTTP API认证的使用说明.
+
+v3.5
+1.优化了kcp参数,速度有所提升.
+2.修复了socks无法正常工作的问题.
+3.修正了文档中的一些描述.
+4.tcp代理增加了kcp协议传输数据.
+5.优化了死循环检查,增加了添加本地IP参数,当VPS在nat设备后面,
+  vps上网卡IP都是内网IP,这个时候可以通过-g参数添加vps的外网ip防止死循环.
+6.增加了--daemon参数,可以后台运行程序哟.  
+
 v3.4
 1.socks5代理新增了用户名密码验证支持.
 2.socks5,http(s)代理增加了kcp传输协议支持.

-#### 手动安装
-#### **1.登录你的VPS,下载守护进程monexec,选择合适你的版本,vps一般选择"linux_amd64.tar.gz"的即可.**  
-下载地址:https://github.com/reddec/monexec/releases  
-比如下载到/root/proxy/  
-执行:  
-```shell  
-mkdir /root/proxy/  
-cd /root/proxy/  
-wget https://github.com/reddec/monexec/releases/download/v0.1.1/monexec_0.1.1_linux_amd64.tar.gz

-### 0.生成加密通讯需要的证书文件  
-  
+### **调试输出**   
+默认情况下,日志输出的信息不包含文件行数,某些情况下为了排除程序问题,快速定位问题,  
+可以使用--debug参数,输出代码行数和毫秒时间.  
+
+### **使用日志文件**   
+默认情况下,日志是直接在控制台显示出来的,如果要保存到文件,可以使用--log参数,  
+比如: --log proxy.log,日志就会输出到proxy.log方便排除问题.   
+
+
+### **生成加密通讯需要的证书文件**  
 http,tcp,udp代理过程会和上级通讯,为了安全我们采用加密通讯,当然可以选择不加密通信通讯,本教程所有和上级通讯都采用加密,需要证书文件.  
 在linux上并安装了openssl命令，可以直接通过下面的命令生成证书和key文件.  
 `./proxy keygen`  
 默认会在当前程序目录下面生成证书文件proxy.crt和key文件proxy.key。  
  
-### 1.HTTP代理  
+### **后台运行**
+默认执行proxy之后,如果要保持proxy运行,不能关闭命令行.  
+如果想在后台运行proxy,命令行可以关闭,只需要在命令最后加上--daemon参数即可.  
+比如:  
+`./proxy http -t tcp -p "0.0.0.0:38080" --daemon`   
+
+### **守护运行**  
+守护运行参数--forever,比如: `proxy http --forever` ,  
+proxy会fork子进程,然后监控子进程,如果子进程异常退出,5秒后重启子进程.  
+该参数配合后台运行参数--daemon和日志参数--log,可以保障proxy一直在后台执行不会因为意外退出,  
+而且可以通过日志文件看到proxy的输出日志内容.  
+比如: `proxy http -p ":9090" --forever --log proxy.log --daemon`  
+
+### **安全建议**
+当VPS在nat设备后面,vps上网卡IP都是内网IP,这个时候可以通过-g参数添加vps的外网ip防止死循环.  
+假设你的vps外网ip是23.23.23.23,下面命令通过-g参数设置23.23.23.23  
+`./proxy http -g "23.23.23.23"`

 #### **4.1、原理说明**  
-内网穿透,由三部分组成:client端,server端,bridge端；client和server主动连接bridge端进行桥接.  
-当用户访问server端,流程是:  
-1. server主动和bridge端建立连接；  
-1. 然后bridge端通知client端连接bridge端,并连接内网目标端口;  
-1. 然后绑定client端到bridge端和client端到内网端口的连接；  
-1. 然后bridge端把client过来的连接与server端过来的连接绑定；  
+内网穿透,分为两个版本，“多链接版本”和“多路复用版本”，一般像web服务这种不是长时间连接的服务建议用“多链接版本”，如果是要保持长时间连接建议使用“多路复用版本”。
+1. 多链接版本，对应的子命令是tserver，tclient，tbridge。  
+1. 多路复用版本，对应的子命令是server，client，bridge。  
+1. 多链接版本和多路复用版本的参数和使用方式完全一样。  
+1. **多路复用版本的server，client可以开启压缩传输，参数是--c。**   
+1. **server，client要么都开启压缩，要么都不开启，不能只开一个。**    
+
+下面的教程以“多链接版本”为例子，说明使用方法。    
+内网穿透由三部分组成:tclient端,tserver端,tbridge端；tclient和tserver主动连接tbridge端进行桥接.    
+当用户访问tserver端,流程是:   
+1. tserver主动和tbridge端建立连接；

+1. 然后绑定tclient端到tbridge端和tclient端到内网端口的连接；

+// Package xid is a globally unique id generator suited for web scale
+//
+// Xid is using Mongo Object ID algorithm to generate globally unique ids:
+// https://docs.mongodb.org/manual/reference/object-id/
+//
+//   - 4-byte value representing the seconds since the Unix epoch,
+//   - 3-byte machine identifier,
+//   - 2-byte process id, and
+//   - 3-byte counter, starting with a random value.
+//
+// The binary representation of the id is compatible with Mongo 12 bytes Object IDs.
+// The string representation is using base32 hex (w/o padding) for better space efficiency
+// when stored in that form (20 bytes). The hex variant of base32 is used to retain the
+// sortable property of the id.
+//
+// Xid doesn't use base64 because case sensitivity and the 2 non alphanum chars may be an
+// issue when transported as a string between various systems. Base36 wasn't retained either
+// because 1/ it's not standard 2/ the resulting size is not predictable (not bit aligned)
+// and 3/ it would not remain sortable. To validate a base32 `xid`, expect a 20 chars long,
+// all lowercase sequence of `a` to `v` letters and `0` to `9` numbers (`[0-9a-v]{20}`).
+//
+// UUID is 16 bytes (128 bits), snowflake is 8 bytes (64 bits), xid stands in between
+// with 12 bytes with a more compact string representation ready for the web and no
+// required configuration or central generation server.
+//
+// Features:
+//
+//   - Size: 12 bytes (96 bits), smaller than UUID, larger than snowflake
+//   - Base32 hex encoded by default (16 bytes storage when transported as printable string)
+//   - Non configured, you don't need set a unique machine and/or data center id
+//   - K-ordered
+//   - Embedded time with 1 second precision
+//   - Unicity guaranted for 16,777,216 (24 bits) unique ids per second and per host/process
+//
+// Best used with xlog's RequestIDHandler (https://godoc.org/github.com/rs/xlog#RequestIDHandler).
