1、在本地产生秘钥和公钥
[[email protected] git_project]# ssh-keygen -t rsa -C "[email protected]@qq.com" Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): /root/.ssh/id_rsa #在这里输入rsa秘钥所在的目录 Enter passphrase (empty for no passphrase): #输入jacky-lulu账号的密码 Enter same passphrase again: #再次输入jacky-lulu账号的密码 Your identification has been saved in /root/.ssh/id_rsa. #保存秘钥的文件（id_rsa） Your public key has been saved in /root/.ssh/id_rsa.pub. #保存公钥的文件（id_rsa.pub）
2、查看公钥
[[email protected] /]# cd /root [[email protected] ~]# ls -al 总用量 156 dr-xr-x---. 5 root root 4096 12月 31 18:26 . dr-xr-xr-x. 25 root root 4096 12月 31 13:37 .. -rw-------. 1 root root 1595 10月 7 09:49 anaconda-ks.cfg -rw-------. 1 root root 16744 12月 30 21:33 .bash_history -rw-r--r--. 1 root root 18 5月 20 2009 .bash_logout -rw-r--r--. 1 root root 176 5月 20 2009 .bash_profile -rw-r--r--. 1 root root 176 9月 23 2004 .bashrc -rw-r--r--. 1 root root 100 9月 23 2004 .cshrc drwx------. 2 root root 4096 10月 7 09:51 .gconf drwx------. 2 root root 4096 10月 7 09:53 .gconfd -rw-r--r--. 1 root root 66 12月 31 17:16 .gitconfig -rw-r--r--. 1 root root 43838 10月 7 09:49 install.log -rw-r--r--. 1 root root 10033 10月 7 09:46 install.log.syslog -rw-------. 1 root root 35 12月 31 18:26 .lesshst -rw-------. 1 root root 3380 12月 11 21:20 .mysql_history -rw-------. 1 root root 78 11月 10 20:19 .mysql_secret -rw-r--r--. 1 root root 879 11月 5 18:14 .rediscli_history drwx------. 2 root root 4096 12月 31 18:59 .ssh -rw-r--r--. 1 root root 129 12月 4 2004 .tcshrc -rw-------. 1 root root 5190 12月 31 18:18 .viminfo -rw-------. 1 root root 57 12月 10 21:54 .xauthAy9Cwu [[email protected] ~]# cd .ssh [[email protected] .ssh]# ls -l 总用量 12 -rw-------. 1 root root 1743 12月 31 18:59 id_rsa -rw-r--r--. 1 root root 405 12月 31 18:59 id_rsa.pub -rw-r--r--. 1 root root 1184 12月 29 17:10 known_hosts
[[email protected] .ssh]# cat id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAyzSZ+5GNn98KxUkEthl4dg8knuTb8znI/oyZ6kzuObZ7AoOd2T/fJVirHE7FKq0nw5zwUF1xez0F8SEgMzQJuXECmEo86DWaYY+Qhh7KSdw30E8g GVMcJvTbMBbQx/tmb9NrjT44STe+sg6HbW8keFxS8VnpJJww26RhGaZzQz30lA55mNF7H7ELfG9pyApNs9iFZFWGf7T/OWQtDQ5v0quNoW3xqBfn0eMHYe0ebZGnIfLumBE8DZAuxOqK6FHw== j a [email protected]@qq.com
[[email protected] .ssh]# ssh -T [email protected]
3、在github自己账号上输入公钥
4、验证连接github的jacky-lulu账号的公钥是否可行
ssh -T [email protected] The authenticity of host ‘github.com (192.30.253.112)‘ can‘t be established. RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added ‘github.com,192.30.253.112‘ (RSA) to the list of known hosts. Enter passphrase for key ‘/root/.ssh/id_rsa‘: Hi jacky-lulu! You‘ve successfully authenticated, but GitHub does not provide shell access.
5、进入的本地仓库的工程，建立与github的jacky-lulu的连接
[[email protected] home]# cd git_project [[email protected] git_project]# ls -l 总用量 8 -rw-r--r--. 1 root root 28 12月 31 18:32 1.java -rw-r--r--. 1 root root 80 12月 31 18:32 2.java [[email protected] git_project]# ls 1.java 2.java [[email protected] git_project]# git remote add origin https://github.com/jacky-lulu/git_project.git [[email protected] git_project]# git remote origin [[email protected] git_project]# git remote -v origin https://github.com/jacky-lulu/git_project.git (fetch) #从github下载工程的连接 origin https://github.com/jacky-lulu/git_project.git (push) #往github上传工程的连接
6、首先在github上创建一个新工程，名称叫git_project(与本地工程名称同名)
7、往github上push工程git_project
[[email protected] git_project]# git push -u origin master #表示把当前master分支push到github上 (gnome-ssh-askpass:15702): Gtk-WARNING **: cannot open display: error: unable to read askpass response from ‘/usr/libexec/openssh/gnome-ssh-askpass‘ Username for ‘https://github.com‘: jacky-lulu #输入账号名称 (gnome-ssh-askpass:15708): Gtk-WARNING **: cannot open display: error: unable to read askpass response from ‘/usr/libexec/openssh/gnome-ssh-askpass‘ Password for ‘https://[email protected]‘: #输入密码 对象计数中: 26, 完成. 压缩对象中: 100% (19/19), 完成. 写入对象中: 100% (26/26), 2.02 KiB | 0 bytes/s, 完成. Total 26 (delta 2), reused 0 (delta 0) remote: Resolving deltas: 100% (2/2), done. To https://github.com/jacky-lulu/git_project.git * [new branch] master -> master 分支 master 设置为跟踪来自 origin 的远程分支 master。
8、故意在github上修改工程git_project工程的2.java文件在同步到本地
[[email protected] git_project]# git fetch origin #把gitgub远端仓库同步到缓冲区 remote: Counting objects: 3, done. remote: Compressing objects: 100% (3/3), done. remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0 展开对象中: 100% (3/3), 完成. 来自 https://github.com/jacky-lulu/git_project c1f3cea..0c2df23 master -> origin/master [[email protected] git_project]# ls 1.java 2.java [[email protected] git_project]# cat 2.java master 2 master 3 master 4 branch jacky1 master jacky222 branch jacky222222222 [[email protected] git_project]# git merge origin/master #把缓冲区的合并到本地库的master分支上 更新 c1f3cea..0c2df23 Fast-forward 2.java | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) [[email protected] git_project]# cat 2.java master 2 master 3 master 4 branch jacky1 master jacky222 branch jacky222222222 远程仓库修改内容22222222222222222222222222222222222222222222 #同步成功
