编译安装git

    此文介绍在centos7上采用源码方式编译安装 git 2.9.5

1. 安装git依赖的库

   [root@centos7 /service/application]#yum -y install gcc gcc-c++ perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker curl-devel expat-devel gettext-devel openssl-devel zlib-devel

2. 从官网下载git源码包

   [root@centos7 ~/tools]# wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.9.5.tar.xz

• 解压源码包：

  [root@centos7 ~/tools]#tar -xvf git-2.9.5.tar.xz

• 进入解压后的目录执行编译配置，编译，编译安装。此处选择的是安装在/service/application目录下。

  [root@centos7 ~/tools]#cd git-2.9.5/
  [root@centos7 ~/tools]#./config --prefix=/service/application
  [root@centos7 ~/tools]#make
  [root@centos7 ~/tools]#make install

• 加入环境变量

  [root@centos7 ~]# echo "export PATH=/service/application/bin" >> /etc/profile
  [root@centos7 ~]# source /etc/profile

相关错误总结：

1. 如果在make过程中报如下错误：

      Can't locate ExtUtils/MakeMaker.pm in @INC (@INC contains: inc /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at inc/Module/Install/Makefile.pm line 4.
   BEGIN failed--compilation aborted at inc/Module/Install/Makefile.pm line 4.
   Compilation failed in require at inc/Module/Install.pm line 307.

   说明没有安装 perl-ExtUtils-CBuilder   perl-ExtUtils-MakeMaker 这两个组件，采取yum安装一下即可。
