CentOS Install git Source

前言

同生活中的许多伟大事件一样，Git 诞生于一个极富纷争大举创新的年代。Linux 内核开源项目有着为数众广的参与者。绝大多数的 Linux 内核维护工作都花在了提交补丁和保存归档的繁琐事务上（1991－2002年间）。到 2002 年，整个项目组开始启用分布式版本控制系统 BitKeeper 来管理和维护代码。官方文档

到了 2005 年，开发 BitKeeper 的商业公司同 Linux 内核开源社区的合作关系结束，他们收回了免费使用 BitKeeper 的权力。这就迫使 Linux 开源社区（特别是 Linux 的缔造者 Linus Torvalds ）不得不吸取教训，只有开发一套属于自己的版本控制系统才不至于重蹈覆辙。他们对新的系统制订了若干目标：

速度
简单的设计
对非线性开发模式的强力支持（允许上千个并行开发的分支）
完全分布式
有能力高效管理类似 Linux 内核一样的超大规模项目（速度和数据量）

安装

git 源码安装。下载源码

1	# wget https://github.com/git/git/archive/v2.21.0.zip

解压缩

# tar zxvf v2.21.0.zip
# cd git-2.20.1

编译命令如下
# # make prefix=/usr/local/git all

如果遇到该错误

http.h:6:23: warning: curl/curl.h: No such file or directory
http.h:7:23: warning: curl/easy.h: No such file or directory
……

1 2	执行命令 # yum install -y curl curl-devel

重新执行编译命令

发现编译报错

执行命令解决这个问题

1	# yum install -y expat-devel

再次重新执行编译命令

发现再次报错

再次重新执行编译命令

git源码编译成功执行执行命令
