git clone时错误解决方案--contos安装git教程

错误信息

error: The requested URL returned error: 401 Unauthorized while accessing https://git.oschina.net/zemo/demo.git/info/refs
fatal: HTTP request failed

解决方案

1、安装依赖

[root@localhost ~]# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc
[root@localhost ~]# yum install  gcc perl-ExtUtils-MakeMaker

2、卸载系统自带的底版本git（1.7.1）

[root@localhost ~]# git --version
git version 1.7.1
[root@localhost ~]# yum remove git

3、编译安装最新的git版本

[root@localhost ~]# cd /soft/      进入下载文件的目录
[root@localhost soft]# wget https://www.kernel.org/pub/software/scm/git/git-2.15.1.tar.xz
[root@localhost soft]# tar -vxf git-2.15.1.tar.xz
[root@localhost soft]# cd git-2.15.1
[root@localhost git-2.15.1]# make prefix=/git all    编译  prefix指定目录
[root@localhost git-2.15.1]# make prefix=/git install    安装  prefix指定目录
[root@localhost git-2.15.1]# echo "export PATH=$PATH:/git/bin" >> /etc/profile    设置环境变量
[root@localhost git-2.15.1]# source /etc/profile    保证环境变量立即生效

4、如果上面下载执行报错，请使用最下面一行的语句

[root@localhost soft]# wget https://www.kernel.org/pub/software/scm/git/git-2.15.1.tar.xz
--2001-02-27 11:29:07--  https://www.kernel.org/pub/software/scm/git/git-2.15.1.tar.xz

[root@localhost soft]# wget https://www.kernel.org/pub/software/scm/git/git-2.15.1.tar.xz --no-check-certificate

5、查看最新的git版本

[root@localhost ~]# git --version
git version 2.15.1

6、遇此问题的解决方法：修改系统时间就OK

Warning: File `../table/table.pro' has modification time 3.9e+08 s in the future

7、第二天打开服务器输入git仍然提示：-bash: git: command not found，解决方法：设置环境变量即可解决

echo "export PATH=$PATH:/git/bin" > /etc/profile.d/git.sh
source /etc/profile.d/git.sh
git --version
