安装依赖软件
# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc # yum install gcc perl-ExtUtils-MakeMaker
卸载系统自带的底版本git（1.7.1）
# git --version git version 1.7.1 # yum remove git
编译安装最新的git版本

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用户使用git，则需要配置下该用户下的环境变量
$ echo "export PATH=$PATH:/usr/local/git/bin" >> ~/.bashrc $ source ~/.bashrc $ git --version git version git-2.1.2
可能遇到报错：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
解决如下：
一.安装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.创建一个软链接到/usr/lib
# ln -s /usr/local/lib/libiconv.so /usr/lib # ln -s /usr/local/lib/libiconv.so.2 /usr/lib
三.然后回到git目录继续编译
# cd /usr/local/scr/git-2.8.3 # make configure # ./configure --prefix=/usr/local --with-iconv=/usr/local/libiconv # make # make install
四.检查一下版本号
# git --version
