Redis集群的离线安装以及原理理解

由 ≯℡__Kan透↙ 提交于 2020-04-21 08:21:57
　　本文主要是记录一下Redis集群在linux系统下离线的安装步骤，毕竟在生产环境下一般都是无法联网的，Redis的集群的Ruby环境安装过程还是很麻烦的，涉及到很多的依赖的安装，所以写了一个文章来进行记录。本文分为两部分，第一部分先通过原生命令的安装来实现redis集群的部署，通过原生命令的安装对于了解redis集群的实现原理有很大的帮助，第二部分通过官方工具Ruby来进行Redis集群的安装，通过Ruby安装Redis集群的时候主要是搭建好Ruby环境，真正Redis集群的安装配置通过Ruby还是很简单的。 　　 一、通过原生命令安装Redis集群（仅做理解Redis集群原理使用） 　　　　1.配置开启所需要的Redis节点 　　　　 　　　　　因为这里只是做一个简单的Redis集群原理演示，所以假设此时Redis服务已经安装完毕，在config文件夹下创建六个redis.conf配置文件，分别为redis-7000.conf、redis-7001.conf、redis-7002.conf、redis-7003.conf、redis-7004.conf、redis-7005.conf。其内容如下： port ${port} daemonize yes dir "/opt/redis/redis/data/" dbfilename "dump-${port}.rdb"

Why does Kernel#require raise a LoadError in Ruby?

由 谁说我不能喝 提交于 2020-04-10 17:41:45
问题 Hi I have wondered for years why you can't use the Kernel#require method for loading gems. For example this will work: #!/usr/bin/ruby -w require 'ruby2d' # => true Here require's owner is Kernel: p Object.method(:require).owner # => Kernel p Kernel.method(:require).owner # => #<Class:Kernel> But this works: p Object.send :require, 'ruby2d' # => true p String.send :require, 'ruby2d' # => false p Kernel.require 'ruby2d' # => false or gem 'ruby2d' # => true p String.send :require, 'ruby2d' # =>
