redis搭建集群ERROR: Could not find a valid gem 'redis-3.0.0' (>= 0) in any repository

步骤:
1,下载redis。官网下载3.0.0版本,之前几的版本不支持集群模式
下载地址:http://download.redis.io/releases/redis-3.0.0.tar.gz

2:上传服务器,解压,编译

3:创建集群需要的目录并拷贝redis

4:修改配置文件redis.conf

5:启动6个redis

6,创建redis集群

cd /usr/local/redis3.0/src
./redis-trib.rb create --replicas 1 192.168.25.129:7001 192.168.25.129:7002 192.168.25.129:7003 192.168.25.129:7004 192.168.25.129:7005 192.168.25.129:7006


6.1执行上面的命令的时候会报错,因为是执行的的脚本,需要
错误内容:/usr/bin/env: ruby: No such file or directory
所以需要安装ruby的环境,这里推荐使用yum install ruby

yum install ruby

6.2然后再执行第步的创建集群命令,还会报错,提示缺少rubygems组件
错误内容:
./redis-trib.rb:24:in `require': no such file to load -- rubygems (LoadError)
from ./redis-trib.rb:24
yum install rubygems

6.3再次执行第步的命令,还会报错,提示不能加载redis,是因为缺少redis的接口
错误内容:
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- redis (LoadError)
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from ./redis-trib.rb:25

gem install redis
这里可能无法安装,因为无法连接gem服务器:
[@zw_22_90 src]# gem install redis --version 3.0.0  
ERROR:  Could not find a valid gem 'redis-3.0.0' (>= 0) in any repository
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)

安装redis过程中遇到题目中的问题解决如下:


需要手工下载并安装:
wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem
gem install -l ./redis-3.2.1.gem



6.4 再次执行第步的命令,正常执行
输入yes,然后配置完成。

至此redis集群即搭建成功!


7,redis-cli命令进入集群环境
[@zw_22_90 src]# redis-cli -c -p 7000
127.0.0.1:7000> quit;


需要注意的是,这个集群是在虚拟机上搭建的,如果在6台真实服务器上搭建集群,需要将这些服务器的防火墙关闭。
