工欲善其事，必先利其器。
在OS X Yosemite 10.10.3安裝最新版本號Xcode。在terminal下能夠發現git已經被安裝。
~ mesut$ git --version
git version 2.3.2 (Apple Git-55)之前就已經註冊而且使用Github了，只是一直都是在window 系統下遠端管理。
如今開始設定Mac管理Github，有一點須要知道的是本地的git倉庫和Githubserver之間是通過ssh加密的。
在終端執行
ozil:tmp mesut$ ssh -v
OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011
usage: ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]
[-D [bind_address:]port] [-e escape_char] [-F configfile]
[-I pkcs11] [-i identity_file]
[-L [bind_address:]port:host:hostport]
[-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]
[-R [bind_address:]port:host:hostport] [-S ctl_path]
[-W host:port] [-w local_tun[:remote_tun]]
[user@]hostname [command]明顯Mac已經安裝了ssh。
1:建立SSH Key
ozil:tmp mesut$ cd ~
ozil:~ mesut$ pwd
/Users/mesut
ozil:~ mesut$ cd .ssh
-bash: cd: .ssh: No such file or directory
ozil:~ mesut$ 進入當前的使用者資料夾。波浪線表示的是當前資料夾。
推斷是否已經安裝了.ssh,避免預設安裝會覆蓋之前安裝的。
明顯當前資料夾沒有該檔案
執行建立 ssh key
ssh-keygen -t rsa -C "youremail@example.com"(你的Github登陸名)接著都是回車，選擇預設的資料夾，預設的password就可以
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/mesut/.ssh/id_rsa):
Created directory '/Users/mesut/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/mesut/.ssh/id_rsa.
Your public key has been saved in /Users/mesut/.ssh/id_rsa.pub.接著能夠在使用者主資料夾裡找到.ssh資料夾，裡面有id_rsa和id_rsa.pub兩個檔案，這兩個就是SSH
Key的祕鑰對
ozil:~ mesut$ cd .ssh
ozil:.ssh mesut$ ls
id_rsa id_rsa.pub2:在Github設定ssh key
登陸Github， “Settings”->"SSH keys"->"Add SSH key"
title:能夠順便填名字
key:在Key文字框裡貼上id_rsa.pub檔案的內容
點選add key 配置完畢
3:測試本地是否和Github連線上
史蒂夫
ozil:.ssh mesut$ ssh -T git@github.com
The authenticity of host 'github.com (xxx)' can't be established.
RSA key fingerprint is xxx.
Are you sure you want to continue connecting (yes/no)? yes
yes回車就可以。
Warning:
Permanently added 'github.com,xxx' (RSA) to the list of known hosts.Hi tanchongshi! You've successfully authenticated, but GitHub does not provide shell access.
4:使用git在本地建立的專案更新到Github
ozil:githubspace mesut$ mkdir hellogithub
ozil:githubspace mesut$ cd hellogithub/
ozil:hellogithub mesut$ ls -ah
. ..
ozil:hellogithub mesut$ git init
Initialized empty Git repository in /Users/mesut/Documents/githubspace/hellogithub/.git/
ozil:hellogithub mesut$ ls -ah
. .. .git
ozil:hellogithub mesut$ touch newfile
ozil:hellogithub mesut$ ls
newfile
ozil:hellogithub mesut$ git add newfile
ozil:hellogithub mesut$ git commit -m 'first commit'
[master (root-commit) 2295d3e] first commit
Committer: >v< <mesut@ozil.local>
Your name and email address were configured automatically based
on your username and hostname. Please check that they are accurate.
You can suppress this message by setting them explicitly. Run the
following command and follow the instructions in your editor to edit
your configuration file:
git config --global --edit
After doing this, you may fix the identity used for this commit with:
git commit --amend --reset-author
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 newfile首先在本地初始化一個git倉庫
因為之前沒有配置username。所以首次commit會有提示。自己主動建立設定方式
$ git config --global user.name "Your Name"
$ git config --global user.email "email@example.com"
為了把本地庫推到遠端server，首先須要在Github上面也建一個專案
在Repository name填上我們的專案名字。description隨便填，別的預設。
然後會生成專案
然後把遠端專案和本地庫關聯
ozil:hellogithub mesut$ git remote add origin git@github.com:tanchongshi/hellogithub.git
ozil:hellogithub mesut$ git push -u origin master
Warning: Permanently added the RSA host key for IP address 'XXX' to the list of known hosts.

so far so good~
