最近使用git命令从github克隆仓库到版本，然后进行提交到github时报错如下：
[root@node1 git_test]# git push origin master
error: The requested URL returned error: 403 Forbidden while accessing https://github.com/jsonhc/git_test.git/info/refs
fatal: HTTP request failed
这台本机没有配置与github的ssh密钥连接，直接通过的是httpds
1、确保不是git版本d低的问题
[root@wadeson wadeson]# git --version
git version 1.7.1
2、从github克隆仓库到本地：
git clone https://github.com/jsonhc/git_test.git
[root@wadeson wadeson]# git clone https://github.com/jsonhc/git_test.git
Initialized empty Git repository in /home/wadeson/git_test/.git/

remote: Total 20 (delta 0), reused 0 (delta 0), pack-reused 20
Unpacking objects: 100% (20/20), done.
3、查看仓库内容，然后增加需要提交的文件
[root@wadeson git_test]# ll
总用量 20
-rw-r--r--. 1 root root 712 7月 31 23:59 flask_first.py
-rw-r--r--. 1 root root 2766 7月 31 23:59 landing.py
-rw-r--r--. 1 root root 1881 7月 31 23:59 menu_list.py
-rw-r--r--. 1 root root 10 7月 31 23:59 README.md
-rw-r--r--. 1 root root 377 7月 31 23:59 total.py
[root@wadeson git_test]# mv ../statistics_ip.py ./
[root@wadeson git_test]# ll
总用量 24
-rw-r--r--. 1 root root 712 7月 31 23:59 flask_first.py
-rw-r--r--. 1 root root 2766 7月 31 23:59 landing.py
-rw-r--r--. 1 root root 1881 7月 31 23:59 menu_list.py
-rw-r--r--. 1 root root 10 7月 31 23:59 README.md
-rw-r--r--. 1 root root 377 8月 3 15:01 statistics_ip.py
4、git config --global user.name "json_hc"
git config --global user.email "json_hc@163.com"
5、git remote set-url origin https://jsonhc@github.com/jsonhc/git_test.git
这条命令就是修改了.git/config下面的这条：
url = https://jsonhc@github.com/jsonhc/git_test.git（原始url为url = https://github.com/jsonhc/git_test.git）
6、git add statistics_ip.py
git commit -m "add statistics_ip.py to statistics ip of nginx"
[root@wadeson git_test]# git commit -m "add statistics_ip.py to statistics ip of nginx"
[master a460f0f] add statistics_ip.py to statistics ip of nginx
1 files changed, 22 insertions(+), 0 deletions(-)
create mode 100644 statistics_ip.py
7、git push -u origin master 第一次推送加上-u
[root@wadeson git_test]# git push -u origin master

然后进入github网站查看已岁推送的文件了
现在使用另外的主机进行开发的时候，首先第一步：
git pull远程仓库的文件
[root@node1 git_test]# git pull origin master

这样才能保证不冲突，得到的是新的版本
下次再次从本地提交就不需要执行以上部分操作：
