一年多前业务使用到redis-cluster集群,然而当时部署时,redis-cluster集群采用的是ruby 语言开发的脚本redis-trib.rb 来进行管理集群的。所以当时给服务器安装了ruby环境。最近项目再一次使用到了redis-cluster集群,所以没多想,直接照着当时的文档记录直接开干,居然行不通了,遇到了各种报错,此次记录在此方便后续使用查看.
服务器环境:centos7.6x84_64位,最小化安装
直接部署ruby环境:
yum -y install ruby ruby-devel yum -y install rubygems [root@localhost ~]# which gem /usr/bin/gem [root@localhost ~]# gem sources --remove http://rubygems.org/ http://rubygems.org/ removed from sources source http://rubygems.org/ not present in cache [root@localhost ~]# gem sources -l ***CURRENT SOURCES *** https://rubygems.org/ [root@localhost ~]# curl -L get.rvm.io | bash -s stable % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 194 100 194 0 0 379 0 --:--:-- --:--:-- --:--:-- 379 curl: (7) Failed connect to raw.githubusercontent.com:443; 拒绝连接
于是添加淘宝ruby源:
[root@localhost ~]# gem sources --add https://ruby.taobao.org/ https://ruby.taobao.org/ added to sources Error fetching https://ruby.taobao.org/: hostname "ruby.taobao.org" does not match the server certificate (https://ruby.taobao.org/specs.4.8.gz)
原来是taobao Gems 源已停止维护,现由 ruby-china 提供镜像服务,即我们要换源
参考地址:https://blog.csdn.net/chris_ime/article/details/52013349
gem sources -a https://gems.ruby-china.com/ [root@localhost ~]# gem sources -a https://gems.ruby-china.com/ https://gems.ruby-china.com/ added to sources [root@localhost ~]# gem sources -l *** CURRENT SOURCES *** https://rubygems.org/ https://gems.ruby-china.com/
安装RVM:

报错了,根据提示如下操作:

The installer no longer auto-adds root or users to the rvm group. Admins must do this. Also, please note that group memberships are ONLY evaluated at login time. This means that users must log out then back in before group membership takes effect! Thanks for installing RVM [root@localhost soft]# echo $? 0
到此处rvm安装成功
加载rvm环境:
[root@localhost soft]# find / -name rvm -print /usr/local/rvm /usr/local/rvm/src/rvm /usr/local/rvm/src/rvm/bin/rvm /usr/local/rvm/src/rvm/lib/rvm /usr/local/rvm/src/rvm/scripts/rvm /usr/local/rvm/bin/rvm /usr/local/rvm/lib/rvm /usr/local/rvm/scripts/rvm [root@localhost soft]# source /usr/local/rvm/scripts/rvm
rvm查看当前可以安装的ruby环境的版本:

此次演示ruby环境安装的是ruby-2.4.6:
[root@localhost soft]# rvm install 2.4.6 Searching for binary rubies, this might take some time. No binary rubies available for: centos/7/x86_64/ruby-2.4.6. Continuing with compilation.

Install of ruby-2.4.6 - #complete Ruby was built without documentation, to build it run: rvm docs generate-ri [root@localhost soft]# [root@localhost soft]# echo $? 0
此时ruby-2.4.6环境安装成功
查看当前ruby的版本:
[root@localhost soft]# ruby --version
ruby 2.4.6p354 (2019-04-01 revision 67394) [x86_64-linux]
切换到ruby-2.4.6环境:
[root@localhost soft]# rvm use 2.4.6
Using /usr/local/rvm/gems/ruby-2.4.6
[root@localhost soft]# ruby --version
ruby 2.4.6p354 (2019-04-01 revision 67394) [x86_64-linux]
把ruby-2.4.6环境设置成默认:
[root@localhost soft]# rvm use 2.4.6 --default
Using /usr/local/rvm/gems/ruby-2.4.6
[root@localhost soft]# ruby --version
ruby 2.4.6p354 (2019-04-01 revision 67394) [x86_64-linux]
安装redis.gem 默认直接安装的是redis-4.1.3:
[root@localhost soft]# gem install redis Fetching redis-4.1.3.gem Successfully installed redis-4.1.3 Parsing documentation for redis-4.1.3 Installing ri documentation for redis-4.1.3 Done installing documentation for redis after 1 seconds 1 gem installed [root@localhost soft]# echo $? 0
安装成功:
[root@localhost soft]# /data/soft/redis-4.0.12/src/redis-trib.rb Usage: redis-tribcreate host1:port1 ... hostN:portN --replicas check host:port info host:port fix host:port --timeout reshard host:port
友情提示:
在管理redis-cluster集群时,经常会使用到rvm环境,每次执行/data/soft/redis-4.0.12/src/redis-trib.rb 命令时,总得提前加载source /usr/local/rvm/scripts/rvm
然后切换到ruby-2.4.6 环境: rvm use 2.4.6 ;有点繁琐,所以直接写入到环境变量文件,这样在登录这台安装有redis-trib.rb命令的机器时,会自动加载ruby环境,是可以减少每次在命令行执行加载rvm的命令
[root@mysql-redis182 ~]# cat .bashrc #.bashrc #User specific aliases and functions alias rm='rm -i' alias cp='cp -i' alias mv='mv -i' #Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi ### [[ -s "/usr/local/rvm/scripts/rvm" ]] && . "/usr/local/rvm/scripts/rvm" rvm use 2.4.6 >/dev/null 2>&1
