Git第七阶段：http/https proxy/ssh proxy/git proxy

一、http proxy | https proxy
git config --global http.proxy http://proxy.bizerba.com:8080
git config --global https.proxy https://proxy.bizerba.com:8080

unset proxy:
git config --global --unset http.proxy
git config --global --unset https.proxy

二、ssh proxy（access your own git repo like git@github.com:user/yourrepo.git）
!!! generate ssh key, and upload public key to github,make you be able clone your repo like:
git clone git@github.com:user/yourrepo.git

but if you are behind a proxy , you need to:
windows 10:
在.ssh文件夹下面新建config文件，内容如下：

Host github.com
    ProxyCommand        connect -H user_ip:user_port %h %p
    ForwardAgent        yes

linux:
在.ssh文件夹下面新建config文件，内容如下：

Host github.com
    ProxyCommand          nc -X connect -x your_ip:your_port %h %p
    ServerAliveInterval   10

三、git proxy( optional to access git repo like git@github.com:user/yourrepo.git )
# step1: download socat | oe-git-proxy |
$ sudo apt-get install socat
$ wget http://git.yoctoproject.org/cgit/cgit.cgi/poky/plain/scripts/oe-git-proxy
$ cp oe-git-proxy ~/bin
$ chmod +x ~/bin/oe-git-proxy

# step2: modify proxy env
sudo vim .profile
export http_proxy=http://proxy.bizerba.com:xxxx
export https_proxy=https://proxy.bizerba.com:xxxx
export ftp_proxy=http://proxy.bizerba.com:xxxx
#export ALL_PROXY=socks://proxy.bizerba.com:xxxx
#export all_proxy=socks://proxy.bizerba.com:xxxx
export no_proxy=http://proxy.bizerba.com:xxxx

export GIT_PROXY_COMMAND="oe-git-proxy"
export NO_PROXY=$no_proxy

# step3: login
su - username

# step4: modify git proxy setting
git config --global core.gitproxy ~/bin/oe-git-proxy

其他思路：
git config --global url."https://".insteadOf git://
