安裝依賴軟體
# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc
# yum install gcc perl-ExtUtils-MakeMaker
解除安裝系統自帶的底版本git（1.7.1）
# git --version
git version 1.7.1
# yum remove git
編譯安裝最新的git版本
連結：https://pan.baidu.com/s/1YnhtIN4ZJmbcv4ohQ81Evg 密碼：hgd4 //百度雲下載地址，下載好放到/usr/local/src
cd /usr/local/src/
# tar -vxf git-2.1.2.tar
# cd git-2.1.2
# make prefix=/usr/local/git all
# make prefix=/usr/local/git install
# echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/profile
# source /etc/profile
# git --version
git version git-2.1.2
======================================================================
如果是非root使用者使用git，則需要配置下該使用者下的環境變數
$ echo "export PATH=$PATH:/usr/local/git/bin" >> ~/.bashrc
$ source ~/.bashrc
$ git --version
git version git-2.1.2
可能遇到報錯：utf8.c:463: undefined reference to `libiconv'
LINK git-credential-store libgit.a(utf8.o): In function `reencode_string_iconv': /usr/src/git-2.8.3/utf8.c:463: undefined reference to `libiconv' libgit.a(utf8.o): In function `reencode_string_len': /usr/src/git-2.8.3/utf8.c:502: undefined reference to `libiconv_open' /usr/src/git-2.8.3/utf8.c:521: undefined reference to `libiconv_close' /usr/src/git-2.8.3/utf8.c:515: undefined reference to `libiconv_open' collect2: ld returned 1 exit status make: *** [git-credential-store] Error 1
解決如下：
一.安裝libiconv
# cd /usr/local/src # wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz # tar -zxvf libiconv-1.14.tar.gz # cd libiconv-1.14 # ./configure --prefix=/usr/local/libiconv && make && make install
二.建立一個軟連結到/usr/lib
# ln -s /usr/local/lib/libiconv.so /usr/lib # ln -s /usr/local/lib/libiconv.so.2 /usr/lib
三.然後回到git目錄繼續編譯
# cd /usr/local/scr/git-2.8.3 # make configure # ./configure --prefix=/usr/local --with-iconv=/usr/local/libiconv # make # make install
四.檢查一下版本號
# git --version
