git安装--linux下的安装

通常linux自带git版本很旧，会有必定问题，能够先卸载系统自带git：

yum remove git
下载及安装git：

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 --with-curl=/home/{username}/curl/
make
make install
echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
source /etc/bashrc
配置curl很重要。 
可能出现的问题，少一些系统库： 
1.编译git时报错： zlib.h: No such file or directory
缺乏 zlib的头文件， 开发包没装，

yum install zlib （系统默认已经装上）
yum install zlib-devel
解决

2.提示make cc Command not found

yum install gcc
3.make[1]: * [perl.mak] Error 2 make: * [perl/perl.mak] Error 2
执行：

yum install perl-ExtUtils-MakeMaker package.
进行安装 
出现错误二： 
/bin/sh: msgfmt: command not found

yum install gettext-devel
可解决！
