编译IPFS

1.下载源码

go get -u -d github.com/ipfs/go-ipfs

2.编译

make install

3.编译过程中运动的问题
设置代理（前提是你的电脑已经通过ss开始了科学sw)
(1)如果提示gx_v0.14.0_linux-amd64.tar.gz和gx-go_v1.9.0_linux-amd64.tar.gz下载不下来，需要设置代理
修改源码go-ipfs下的bin/dist_get文件
将通过curl下载的地方改为
//1080:是你配置在ss的本地端口

try_download "$dl_url" "$dl_output" "curl --socks5-hostname 127.0.0.1:1080 --silent --fail --output '$dl_output' '$dl_url'" && return

(2)继续make install会提示下面的依赖包找不到

gx install --global
[get ] [fetch]         QmdxUuburamoF6zF9qjeQC4WYcWGbWuRmdLacMEsW8ioD8 gogo-protobuf
......
[get ] [fetch]         QmRBaUEQEeFWywfrZJ64QgsmvcqgLSK3VbvGMR2NM2Edpf go-libp2p

需要设置全局代理
步骤1：下载polipo

sudo apt install polipo

步骤2：

sudo vim /etc/polipo/config

将原来的内容覆盖为以下内容

# This file only needs to list configuration variables that deviate
# from the default values.  See /usr/share/doc/polipo/examples/config.sample
# and "polipo -v" for variables you can tweak and further information.

#logSyslog = true
#logFile = /var/log/polipo/polipo.log

# This file only needs to list configuration variables that deviate
# from the default values. See /usr/share/doc/polipo/examples/config.sample
# and "polipo -v" for variables you can tweak and further information.
logSyslog = false
logFile = "/var/log/polipo/polipo.log"

socksParentProxy = "127.0.0.1:1080"
socksProxyType = socks5

chunkHighMark = 50331648
objectHighMark = 16384

serverMaxSlots = 64
serverSlots = 16
serverSlots1 = 32

proxyAddress = "0.0.0.0"
proxyPort = 8123

设置代理

export http_proxy="http://127.0.0.1:8123/"
export https_proxy="http://127.0.0.1:8123/"

重启polipo

/etc/init.d/polipo restart

不要切换终端，直接在这个终端进行make install（代理只是临时的）
这样就发现gx install --global终于可以往下走了

gx install --global
[done] [fetch]   6.98s QmZmmuAXgX73UQmX1jRKjTGmjzq24Jinqkq8vzkBtno4uX go-is-domain
[get ] [fetch]         QmdxUuburamoF6zF9qjeQC4WYcWGbWuRmdLacMEsW8ioD8 gogo-protobuf

不过后面又再下，又一直下不下来，不知原因。。。

ERROR: from shell.Get(): Post https://ipfs.io/api/v0/get?arg=QmPJUtEJsm5YLUWhF6imvyCH8KZXRJa9Wup7FDMwTy5Ufz&create=true: dial tcp 31.13.78.66:443: connect: connection timed out

因为编译需要在sudo下执行，而上面设置的代理在sudo下是不生效的，所以sudo make install会因为gopath改变而重新下载依赖包。在编译的时候把/etc/sudoers 里面的

Defaults        env_reset

改为

Defaults        !env_reset

这样sudo make install不会提示找不到go，也不会提示你的go-ipfs不在gopath目录
