利用基于go的tunnel-by-cosiner翻墙

如果你的linux vps里安装的go的版本为1.4.x,则需另外安装go 1.5.x:

wget https://storage.googleapis.com/golang/go1.5.4.linux-386.tar.gz

(wget https://storage.googleapis.com/golang/go1.5.4.linux-amd64.tar.gz ,如果你的系统是64位）

tar zxvf go1.5.4.linux-386.tar.gz -C /usr/local/

mv /usr/local/go /usr/local/go1.5.4

git clone https://github.com/cosiner/tunnel tunnel-by-cosiner
cd tunnel-by-cosiner
mkdir gospace
cd gospace
export GOPATH=~/tunnel-by-cosiner/gospace/ 或export GOPATH=`pwd`
export GOROOT=/usr/local/go1.5.4/ （这一步不可少！）

root@AR:~/tunnel-by-cosiner/gospace# /usr/local/go1.5.4/bin/go get github.com/cosiner/tunnel
root@AR:~/tunnel-by-cosiner/gospace# ls
pkg src
root@AR:~/tunnel-by-cosiner/gospace# /usr/local/go1.5.4/bin/go install github.com/cosiner/tunnel
root@AR:~/tunnel-by-cosiner/gospace#
root@AR:~/tunnel-by-cosiner/gospace# which tunnel
root@AR:~/tunnel-by-cosiner/gospace# find / -name tunnel
/usr/local/go1.5.4/bin/tunnel
^C
root@AR:~/tunnel-by-cosiner/gospace# ls /usr/local/go1.5.4/bin/
go godoc gofmt tunnel
root@AR:~/tunnel-by-cosiner/gospace#

直接运行/usr/local/go1.5.4/bin/go install github.com/cosiner/tunnel 会遇到错误：
can't load package: package github.com/cosiner/tunnel: cannot find package "github.com/cosiner/tunnel" in any of:
/usr/local/go1.5.4/src/github.com/cosiner/tunnel (from $GOROOT)
/root/tunnel-by-cosiner/gospace/src/github.com/cosiner/tunnel (from $GOPATH) 。
必须先运行 /usr/local/go1.5.4/bin/go get github.com/cosiner/tunnel ，再运行
/usr/local/go1.5.4/bin/go install github.com/cosiner/tunnel才不会遇到错误。

root@AR:~/tunnel-by-cosiner/gospace# /usr/local/go1.5.4/bin/tunnel --help
Usage of /usr/local/go1.5.4/bin/tunnel:
-conf string
config file in json (default "tunnel.json")
-local
run as local server
-remote
run as remote server
root@AR:~/tunnel-by-cosiner/gospace# cp ../tunnel.json.sample tunnel.json

root@AR:~/tunnel-by-cosiner/gospace# ls

pkg  src  tunnel.json

root@AR:~/tunnel-by-cosiner/gospace# nano tunnel.json

(把tunnel.json的第16行里的127.0.0.1改为0.0.0.0）

root@AR:~/tunnel-by-cosiner/gospace# nohup /usr/local/go1.5.4/bin/tunnel -conf tunnel.json -remote > /dev/null &

(这样，服务器端就搭建好了）

在客户机器上。

linux桌面系统下，客户端的搭建跟linux vps大同小异。只是最后编辑tunnel.json时，把tunnel.json的第16行里的127.0.0.1改为你的vps的ip.然后，

~/tunnel-by-cosiner/gospace$ nohup /usr/local/go1.5.4/bin/tunnel -conf tunnel.json -local > /dev/null &

(这样,客户端就搭建好了）

设置本地机器的浏览器的socks5代理为127.0.0.1:7778,即可翻墙。

在mac下。参考http://briteming.blogspot.com/2015/10/macgo.html，搭建go的1.5.x 版。然后，

yudeMacBook-Air:~ brite$ git clone https://github.com/cosiner/tunnel tunnel-by-cosiner

yudeMacBook-Air:~ brite$ cd tunnel-by-cosiner

yudeMacBook-Air:tunnel-by-cosiner brite$ ls

LICENSE main.go server

README.md proxy tunnel.json.sample

yudeMacBook-Air:tunnel-by-cosiner brite$ mkdir gospace

yudeMacBook-Air:tunnel-by-cosiner brite$ cd gospace

yudeMacBook-Air:gospace brite$ export GOPATH=`pwd`

yudeMacBook-Air:gospace brite$ echo $GOROOT

/usr/local/go/

yudeMacBook-Air:gospace brite$ which go

/usr/local/go/bin/go

yudeMacBook-Air:gospace brite$ go version

go version go1.5.1 darwin/amd64

yudeMacBook-Air:gospace brite$ go get github.com/cosiner/tunnel

yudeMacBook-Air:gospace brite$ ls

bin pkg src

yudeMacBook-Air:gospace brite$ ls bin

tunnel

yudeMacBook-Air:gospace brite$ cd bin

yudeMacBook-Air:bin brite$ ls

tunnel

yudeMacBook-Air:bin brite$ pwd

/Users/brite/tunnel-by-cosiner/gospace/bin

yudeMacBook-Air:bin brite$ cp /Users/brite/tunnel-by-cosiner/tunnel.json.sample tunnel.json

yudeMacBook-Air:bin brite$ ls

tunnel tunnel.json

yudeMacBook-Air:bin brite$ nano tunnel.json

(把tunnel.json的第16行里的127.0.0.1改为你的vps的ip)

yudeMacBook-Air:bin brite$ nohup ./tunnel -conf tunnel.json -local > /dev/null &

 这样，客户端就搭建好了。

设置本地机器的浏览器的socks5代理为127.0.0.1:7778,即可翻墙。

在window桌面系统下。作者提供了客户端程序：

参考http://stackoverflow.com/questions/27772831/golang-c-source-files-not-allowed-when-not-using-cgo里面的一句话“if you install Go 1.4 and then install Go 1.5. But don't change GOROOT environment variables. Change GOROOT point to GO 1.5 path.“

因为我没删除之前安装的go1.4版，所以必须运行一下export GOROOT=/usr/local/go1.5.4/ （这一步不可少！）
