在越狱的iphone上，安装go环境并编译Shadowsocks-go以翻墙

My last blog talked about how to create a Socks 5 proxy with shadowsocks-nodejs and shadowsocks python version on iPhone,  well, they all work perfectly only that the nodejs version costs too much of  RAM and python version is a little bit slow, however, thanks to @cyfdecyf , we got golang version of shadowsocks, it has the same speed(maybe better) with nodejs version but cost very little RAM, so i choose the golang version for my daily use and nodejs version as a backup. Okay, let's begin to install google go language and shadowsocks-go on iPhone,  i believe i am the first person to do this.

上一篇博客介绍了如何在iPhone上利用shadowsocks-nodejs和Python版创建Socks 5代理，他们运行的很好，只是nodejs版本消耗内存太多而Python版因为缺少gevent而比较慢，还好有人开发了Go版的，它拥有nodejs版的速度，却只用少量的内存，所以我现在主要用Go版的，nodejs版的作为备用。下面就开始在iPhone上安装Google Go 的编译环境和并编译shadowsocks-go for iPhone,我应该是第一个这么做的吧 ：）

If you want to be lazy, you can download compiled binary of shadowsocks-go client, it can only run inside  jailbreak iPhone, iPad and iPod Touch
如果你想偷懒，可以直接下载我编译好的，只能在越狱的iPhone，iPad，iPod Touch上使用。

Install Google Golang on iPhone

• SSH into iPhone and run the following command:

wget http://cydia.radare.org/debs/go_15490_iphoneos-arm.deb

sudo dpkg -i go_15490_iphoneos-arm.deb

• Now we have go languages installed, thanks +minux ma  for porting Golang to iOS, also thanks @trufae for making a working .deb package, they made it easy to install go on iPhone. However @trufae forgot to sign it's package, so we need to sign it after installation,
• SSH into iPhone and run:

sudo apt-get install ldid
sudo ldid -s /var/go/bin/go
sudo ldid -s  /var/go/src/cmd/*
sudo ldid -s  /var/go/pkg/obj/cmd/* 

Config Google  Golang on iPhone

• We need to add go to our PATH and also set GOPATH variable, GNU coreutils could help, it can set alias, PATH, export some variable and so.

mkdir ~/gosrc
sudo apt-get install coreutils

• Next, we need to edit /etc/profile.d/coreutils.sh with vim or nano:

sudo vim /etc/profile.d/coreutils.sh

• Add the following codes and save:

export GOPATH="/var/mobile/gosrc"
export GOROOT="/var/go"
export PATH="/var/go/bin:$PATH"

• Now make our settings on the fly:

source /etc/profile.d/coreutils.sh 

Compile Shadowsocks-go on iPhone

• Download Shadowsocks-go source code and unzip it:

wget --no-check-certificate https://github.com/shadowsocks/shadowsocks-go/archive/master.zip

unzip master.zip

• We will have a  folder called shadowsocks-go-master at the current directory, now still need some trick:

mkdir -p ~/gosrc/src/github.com/shadowsocks/shadowsocks-go

cp -r shadowsocks-go-master/shadowsocks ~/gosrc/src/github.com/shadowsocks/shadowsocks-go/

cd shadowsocks-go-master/cmd/shadowsocks-local/

go build

sudo cp shadowsocks-local /usr/bin/

• If no mistake, now we will have a excutable shadowsocks-go client named shadowsocks-local in /usr/bin, we can run it now, only for iPhone.

Run Shadowsocks-go on iPhone

• First  create a config file for shadowsocks-go:

cd ~
touch config.json
vim config.json

• Copy and paste the following code and save

{

    "server":"your server ip or domain name",
    "server_port":11111,
    "local_port":9090,
    "password":"your password, make this password long and complex enough",
    "timeout":600,
    "method":"rc4"
}

• Also copy config.json to server, shadowsocks-go server version can be downloaded here:
• on the server side:

nohup shadowsocks-server -c ~/config.json > /dev/null 2>&1 &

• Or we can set an alias for this long command:

vim ~/.bashrc
alias sgp="nohup shadowsocks-server -c ~/config.json > /dev/null 2>&1 &"
source ~/.bashrc

• on iPhone side:

nohup shadowsocks-local -c ~/config.json > /dev/null 2>&1 &

• Or we can set an alias for this long command:

sudo vim /etc/profile.d/coreutils.sh
alias sgp="nohup shadowsocks-local -c ~/config.json > /dev/null 2>&1 &"
source /etc/profile.d/coreutils.sh

Create PAC file to use shadowsocks-go proxy on iPhone.
