环境要求

  • ruby环境version >= 2.2.2. 使用ruby脚本安装集群，所以os要安装ruby。 不然报错：
/usr/bin/env: ruby: No such file or directory

  • 需要安装ruby访问redis的客户端

    不然报错：

[root@hadoop-slave-002 rediscluster]# ./redis-trib.rb create --replicas 1 192.168.253.131:7000 192.168.253.131:7001  192.168.253.131:7002 192.168.253.131:7003 192.168.253.131:7004 192.168.253.131:7005

	from /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require'
	from ./redis-trib.rb:25:in `<main>'


执行命令

gem install redis

报错：

[root@hadoop-slave-002 rediscluster]# gem install redis
Fetching: redis-4.0.1.gem (100%)
ERROR:  Error installing redis:
	redis requires Ruby version >= 2.2.2.

  • 安装2.2以上版本ruby

    删除已有ruby版本

    yum remove ruby

    最小依赖安装。 安装依赖：

    yum -y groupinstall "Development Tools"
yum -y install gdbm-devel libdb4-devel libffi-devel libyaml libyaml-devel ncurses-devel openssl-devel readline-devel tcl-devel

    wget http://cache.ruby-lang.org/pub/ruby/2.2/ruby-2.2.3.tar.gz -P /root/rpmbuild/SOURCES

wget https://raw.githubusercontent.com/tjinjin/automate-ruby-rpm/master/ruby22x.spec -P /root/rpmbuild/SPECS

rpmbuild -bb /root/rpmbuild/SPECS/ruby22x.spec

yum -y localinstall /root/rpmbuild/RPMS/x86_64/ruby-2.2.3-1.el7.centos.x86_64.rpm

    报错：

    [root@hadoop-slave-002 rediscluster]# rpmbuild -bb rpmbuild/SPECS/ruby22x.spec
bash: rpmbuild: command not found...

  • 安装rmpbuild

    #查找合适的rpm-build包
yum list |grep rpm-build 
yum install -y rpm-build.x86_64

安装成功提示：16384表示集群中的 16384 个槽都有至少一个主节点在处理， 集群运作正常。

[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.

spring redis 集群

redis集群版本4.1；spring redis cliet 2.8 报错：

org.springframework.beans.factory.BeanCreationException:
 Error creating bean with name 'jedisCluster' defined in file

==将redis client2.8改为2.9,同时加上commons-pool2依赖。==
