centos7 安装Git

安装git前先检查一下是否有旧版本git

通过git –version查看系统带的版本，如果有就删除

# yum remove git

1.安装依赖的包

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
yum install  gcc perl-ExtUtils-MakeMaker
2.下载git源码并解压

wget https://github.com/git/git/archive/v2.3.0.zip
unzip v2.3.0.zip（或：unzip v2.3.0）
进入解压的目录

cd git-2.3.0
3.编译安装

安装在/usr/local/下

make prefix=/usr/local/git all
make prefix=/usr/local/git install

　编译时出现如下异常：

      libgit.a(utf8.o): In function `reencode_string_iconv':
      /root/git-2.3.0/utf8.c:463: undefined reference to `libiconv'
      libgit.a(utf8.o): In function `reencode_string_len':
      /root/git-2.3.0/utf8.c:502: undefined reference to `libiconv_open'
      /root/git-2.3.0/utf8.c:521: undefined reference to `libiconv_close'
      /root/git-2.3.0/utf8.c:515: undefined reference to `libiconv_open'
      collect2: ld 返回 1
      make: *** [git-credential-store] 错误 1
  
 

　　下载并安装libiconv

      cd ..
      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
  
 

　　返回git在此编译安装

      cd ../git-2.3.0
      make clean
  autoconf

      ./configure --prefix=/usr/local --with-iconv=/usr/local/libiconv/
      make install
  
 

错误如下：

         In file included from progname.c:26:0:
          ./stdio.h:1010:1: error: ‘gets’ undeclared here (not in a function)
       _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
          ^
          make[2]: *** [progname.o] Error 1
          make[2]: Leaving directory `/usr/local/src/zabbix-2.4.7/libiconv-1.14/srclib'
       make[1]: *** [all] Error 2
       make[1]: Leaving directory `/usr/local/src/zabbix-2.4.7/libiconv-1.14/srclib'
          make: *** [all] Error 2
  
 

解决办法：

vi libiconv-1.14/srclib/stdio.in.h
 

将698行的代码：_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");替换为：

      #if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16)
      _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");#endif
  
 

此时执行git --version仍然提示command not found，git已经安装成功，可能是配有配置环境变量

4.配置环境变量

vim /etc/profile
在文件最后一行添加：export PATH=/usr/local/git/bin:$PATH，保存退出

发现仍然不行，这是因为配置还未生效，不重启系统，使用source命令立即生效

source /etc/profile
然后git --version，提示 git version 2.3.0，已安装成功。

我这是用一个新linux服务器安装的，所有步骤都以列出，如有问题请联系
