redis4.0.1集群安装部署

安装环境

序号	项目	值
1	OS版本	Red Hat Enterprise Linux Server release 7.1 (Maipo)
2	内核版本	3.10.0-229.el7.x86_64
3	Redis	redis-4.0.1
4	Ruby	ruby 2.3.4p301 (2017-03-30 revision 58214) [x86_64-linux]

节点信息规划

本来只准备部署7001-7004 4个实例，但是redis集群提示最少需要3个主节点，6个节点才能完成启动，所以后面2个是后来加的。

注意：这里因为是测试环境，所以将所有实例都放在了一台机器上，生产建议主备节点不要放在一台机器上

序号	IP地址	端口	主备	节点配置文件
1	192.168.9.216	7001	主	/opt/redis-cluster/nodes-7001/redis.conf
2	192.168.9.216	7002	主	/opt/redis-cluster/nodes-7002/redis.conf
3	192.168.9.216	7003	主	/opt/redis-cluster/nodes-7003/redis.conf
4	192.168.9.216	7004	备	/opt/redis-cluster/nodes-7004/redis.conf
5	192.168.9.216	7005	备	/opt/redis-cluster/nodes-7005/redis.conf
6	192.168.9.216	7006	备	/opt/redis-cluster/nodes-7006/redis.conf

环境安装(按照正常安装步骤，碰到问题再解决)

1.下载redis-4.0.1.tar.gz源码包

[root@elk01 opt]# wget http://download.redis.io/releases/redis-4.0.1.tar.gz

2.解压并安装

[root@elk01 opt]# pwd

依次启动各个redis实例

#创建redis集群

创建redis集群使用redis-trib.rb命令，该命令是基于ruby的脚本，需要安装ruby，ruby-gem以及gem-redis

[root@elk01 redis-cluster]# redis-trib.rb create --replicas 1 192.168.9.216:7001 192.168.9.216:7002 192.168.9.216:7003 192.168.9.216:7004

添加国内源命令：gem source -a https://gems.ruby-china.org

删除国外源并添加国内源：gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/
