Centos Git1.7.1升级到Git2.2.1

安装需求:

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

　如果libiconv字符集转换库没安装的话会出现如下错误，请参照安装：

error: ```/utf8.c:463: undefined reference to `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

卸载Centos自带的git1.7.1:

># yum remove git

　　

下载git2.2.1 编译安装 并将git添加到环境变量

># wget https://github.com/git/git/archive/v2.2.1.tar.gz
># tar zxvf v2.2.1.tar.gz
># cd git-2.2.1
># make configure
># ./configure --prefix=/usr/local/git --with-iconv=/usr/local/libiconv
># make all doc
># make install install-doc install-html
># echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
># source /etc/bashrc　

大功告成，Git已成功升级，可查看Git版本号

># git --version
>git version 2.2.1
