fpm是一个ruby实现的对rpmbuild进行封装的打包工具，方便linux系统下定制软件包管理，如下为Nginx打包示例供参考。

工具准备

1. 安装fpm依赖包

   yum -y install ruby-devel gcc make rpm-build rubygems

2. 安装fpm

   gem install fpm
   fpm --version

Nginx打包

1. 准备工作
   安装pcre和openssl包

   yum install pcre pcre-devel openssl openssl-devel

   目录准备:

   mkdir -p /root/build/src
   mkdir -p /root/install/opt
   cd /root/build/src/
   wget http://nginx.org/download/nginx-1.13.4.tar.gz

   安装nginx:

   tar -xvf nginx-1.13.4.tar.gz
   cd nginx-1.13.4
   ./configure --prefix=/root/install/opt/nginx
   make && make install

   安装包后执行脚本（可根据需求定制）：

   cat /root/build/post-install.sh
   #!/bin/bash
useradd nginx -M -s /sbin/nologin
chown nginx:nginx /opt/nginx -R

2.打包

fpm -s dir -t rpm -C /root/install -n nginx -v 1.13.4
--license BSD --url "https://www.nginx.com/"
--post-install /root/build/post-install.sh --iteration 1
--vendor "admin@gmail.com"
--description "Nginx v1.13.4 build in 2017/08/26"
-d "pcre,pcre-devel,openssl,openssl-devel"

注：fpm -C 参数下目录结构为包实际安装目录。

当前目录生成nginx-1.13.4-1.x86_64.rpm包

rpm -ivh nginx-1.13.4-1.x86_64.rpm

[root@centos7-linux build]# rpm -qa| grep nginx
nginx-1.13.4-1.x86_64

[root@centos7-linux build]# ll /opt/nginx/
