git 默认使用 id_rsa，指定私钥方法是：

			
git config core.sshCommand "ssh -i ~/.ssh/id_rsa_example -F /dev/null"
git pull
git push
			
			

			
GIT_SSH_COMMAND="ssh -i ~/.ssh/id_rsa_example -F /dev/null" git clone git@github.com:netkiller/netkiller.github.io.git		
			
			

error: RPC failed; result=22, HTTP code = 413 | 18.24 MiB/s
fatal: The remote end hung up unexpectedly
			

git config http.postBuffer 524288000
			

使用自颁发 ssl 证书时需要开启，否则无法 clone 和 push

			
export GIT_SSL_NO_VERIFY=true			
			
			

			
git config http.sslVerify "false"
