安装git

一、先安装编译时依赖的包

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

二、卸载旧版本

yum remove git

三、下载与安装

cd ~
wget https://www.kernel.org/pub/software/scm/git/git-2.15.1.tar.xz
tar -vxf git-2.15.1.tar.xz
cd git-2.15.1
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

make prefix=/usr/local/git all编译的时候出现了错误：

 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

解决方法

一、安装libiconv

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、回到git目录继续编译

cd ~/git-2.15.1(我放在家目录)
make configure
./configure --prefix=/usr/local --with-iconv=/usr/local/libiconv
make
make install

四、编辑环境变量配置（给到所有用户）: vim /etc/profile

1 export PATH=$PATH:/usr/local/git/bin  或者 echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc (需要退出 root 用户再操作. 否则就只有root用户内部才生效了)  
2 刷新配置：source /etc/bashrc

五、查看GIT版本

git --version  
git version 2.15.1
