但看其他 mirror 好像都被停用支持 6.7 版本了..

This directory (and version of CentOS) is deprecated.  For normal users,
you should use /6/ and not /6.7/ in your path. Please see this FAQ
concerning the CentOS release scheme:

https://wiki.centos.org/FAQ/General

If you know what you are doing, and absolutely want to remain at the 6.7
level, go to http://vault.centos.org/ for packages. 

Please keep in mind that 6.0, 6.1, 6.2, 6.3, 6.4 , 6.5, 6.6 and 6.7 no longer gets any updates, nor
any security fix's.

請問還有6.7能用的 mirror 或是老版本 redhat 安裝 git 的方式嗎?

終於找到了活著的 mirror 了，用以下命令解決

wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-1.8.3.4.tar.gz --no-check-certificate
wget -O git-manpages-1.8.3.4.tar.gz https://mirrors.edge.kernel.org/pub/software/scm/git/git-manpages-1.8.3.4.tar.gz --no-check-certificate

$ tar xvfz git-1.8.3.4.tar.gz
$ cd git-1.8.3.4
$ ./configure
$ make
$ sudo make prefix=/usr install
$ git --version
git version 1.8.3.4
