先下载 wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.9.5.tar.gz
解压文件 tar -zxf git-2.9.5.tar.gz
进入git文件夹 cd git-2.9.5
通过源代码编译安装测试 make configure
提示 /bin/sh: autoconf: command not found错误

[root@master git-2.9.5]# make configure
GIT_VERSION = 2.9.5
    GEN configure
/bin/sh: autoconf: command not found
make: *** [configure] Error 127

解决方案：执行 yum install install autoconf automake libtool -y
再执行 make configure

[root@master git-2.9.5]# make configure
    GEN configure

执行指定位置安装 ./configure --prefix=/usr

# 最后三行显示此结果，表示安装成功
configure: creating ./config.status
config.status: creating config.mak.autogen
config.status: executing config.mak.autogen commands

执行 make all doc info 出现下面错误

[root@master git-2.9.5]# make all doc info
