Already installed ruby-2.4.10.
To reinstall use:
rvm reinstall ruby-2.4.10
fpm 安装
gem install fpm
有时会卡住 gem install fpm 需要更换gem 源
gem sources --add http://mirrors.aliyun.com/rubygems/ --remove https://rubygems.org/
安装成功如下

制作rpm包
以zookeeper 为例
下载个zookeeper-3.5.6.tar.gz 的包，解压后修改名称为zookeeper（修改名称非必要），拷贝到opt下（当然也可以是其他目录）
[xxx bin]# cd /opt/
[xxx opt]# ls
cni containerd rh zookeeper
[xxx opt]# fpm -s dir -t rpm -n zookeeper -v 3.5.6 -f /opt/zookeeper/
Doing `require 'backports'` is deprecated and will not load any backport in the next major release.
Require just the needed backports instead, or 'backports/latest'.
Created package {:path=>"zookeeper-3.5.6-1.x86_64.rpm"}
FPM常用参数：
-s:指定源类型
-t:指定目标类型，即想要制作为什么包
-n:指定包的名字
-v:指定包的版本号
-C:指定打包的相对路径
-d:指定依赖于哪些包
-f:第二次包时目录下如果有同名安装包存在，则覆盖它；
-p:制作的rpm安装包存放路径，不想放在当前目录下就需要指定；
--post-install:软件包安装完成之后所要运行的脚本；同--offer-install
--pre-install:软件包安装完成之前所要运行的脚本；同--before-install
--post-uninstall:软件包卸载完成之后所要运行的脚本；同--offer-remove
--pre-uninstall:软件包卸载完成之前所要运行的脚本；同—before-remove
--prefix:制作好的rpm包默认安装路径；
