1.
下载git源码
https://git-scm.com
2.
根据文档一步步操作
https://git-scm.com/book/en/v2/Getting-Started-Installing-Git
选择installing from source
sudo yum install dh-autoreconf libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev sudo yum install asciidoc xmlto docbook2x sudo yum install getopt sudo ln -s /usr/bin/db2x_docbook2texi /usr/bin/docbook2x-texi make configure ./configure --prefix=/usr make all doc info sudo make install install-doc install-html install-info
3.
上面 make all doc info的时候会报错，实际上我们只需make，然后makeinstall就可以了。如果你想安装其他的doc和info，那么就需要
http://docbook2x.sourceforge.net/
上面的 sudo ln -s /usr/bin/db2x_docbook2texi /usr/bin/docbook2x-texi是失败的，因为你根本没有db2x_docbook2texi
可以根据上面的官网源码安装，但是我试了最后，编译成功，还是无法使用
提示下面的错误
I/O error : Attempt to load network entity http://docbook2x.sf.net/latest/xslt/texi/docbook.xsl
warning: failed to load external entity "http://docbook2x.sf.net/latest/xslt/texi/docbook.xsl"

Unable to recognise encoding of this document at /usr/share/perl5/vendor_perl/XML/SAX/PurePerl/EncodingDetect.pm line .

make[]: *** [user-manual.texi] Error
所以呢，我们用现成编好的

按照作者的方式是可以直接编译过的
