rpm打包过程
【需求】
接触那么久的Linux，还没有试验过怎么打rpm包
【过程】
1、rpm打包准备工作
系统默认的rpmbuild的相关路径
如果想修改这个目录，怎么修改呢？
在/data1/guosong/rpmbuild目录下创建如下目录BUILD BUILDROOT code RPMS SOURCES SPECS SRPMS
还必须修改~/.rpmmacros
%_topdir /data1/guosong/rpmbuild
2、rpm打包过程
打包helloworld需要程序sources文件，spec文件
*编写hellword源文件(hello.c)
#include <stdio.h> int main(){ printf("Hello, World!\n"); return 0; }
*打包成tar文件
创建hello-0.1目录，将hello.c挪到hello-0.1目录中
将tar包转移到/data1/guosong/rpmbuild/SOURCES目录下
*在/data1/guosong/rpmbuild/SPECS目录下编写spec文件
BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root
Summary: hello world rpm package
Name: hello
Version: 0.1
Release: 1
#文件名必须保持一致
Source: hello-0.1.tar.gz
License: GPL
Packager: guosong
Group: Application
%description
This is a simple example for rpm package!
%prep
%setup -q
%build
gcc -o hello hello.c
%install
mkdir -p %{buildroot}/usr/local/bin
install -m 755 hello %{buildroot}/usr/local/bin/hello
%files
# 这里的路径是在buildroot虚拟根基础上的，即%{buildroot}/%{name}-%{version}-%{release}-root/usr/local/bin/hello
/usr/local/bin/hello

*制作rpm包
rpmbuild -bb hello.spec
输出的日志如下：
