install (三台各自执行)

mkdir /redis cd /redis wget -P /redis http://download.redis.io/releases/redis-4.0.1.tar.gz

tar -xzf redis-4.0.1.tar.gz cd redis-4.0.1 make && make install

验证安装：

[root@jp33e503-7-11 redis-4.0.1]# redis- tab键

redis-benchmark  redis-check-aof  redis-check-rdb  redis-cli        redis-sentinel   redis-server

出现上面的命令

whereis redis-server

redis-server: /usr/local/bin/redis-server

将redis-trib.rb 复制到/usr/local/bin

cd src/
cp -rp redis-trib.rb /usr/local/bin/

集群搭建：

创建目录

mkdir -p /redis/cluster/700{1..9}
mkdir -p /redis/cluster/701{0..2}

配置redis 配置文件

[root@jp33e503-7-11 cluster]# pwd /redis/cluster

启动服务（3台主机分别启动）

redis-server /redis/cluster/7001/redis.conf && redis-server /redis/cluster/7002/redis.conf && redis-server /redis/cluster/7003/redis.conf && redis-server /redis/cluster/7004/redis.conf && redis-server /redis/cluster/7005/redis.conf && redis-server /redis/cluster/7006/redis.conf && redis-server /redis/cluster/7007/redis.conf && redis-server /redis/cluster/7008/redis.conf && redis-server /redis/cluster/7009/redis.conf && redis-server /redis/cluster/7010/redis.conf && redis-server /redis/cluster/7011/redis.conf && redis-server /redis/cluster/7012/redis.conf

检查是否启动成功及信息

[root@jp33e503-7-11 cluster]# ps -ef |grep redis root 28364 1 0 13:33 ? 00:00:00 redis-server 172.17.7.11:7001 [cluster] root 29859 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7002 [cluster] root 29861 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7003 [cluster] root 29869 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7004 [cluster] root 29874 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7005 [cluster] root 29879 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7006 [cluster] root 29884 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7007 [cluster] root 29889 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7008 [cluster] root 29891 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7009 [cluster] root 29896 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7010 [cluster] root 29901 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7011 [cluster] root 29906 1 0 13:34 ? 00:00:00 redis-server 172.17.7.11:7012 [cluster]

然后配置下一台，注意修改服务器监听IP地址：

搭建集群

redis 官方提供了一个 redis-trib.rb （src目录下）工具用于搭建集群。很明显是 ruby 写的，所以需要 ruby 环境。

安装 ruby

yum -y install ruby ruby-devel rubygems rpm-build

用 gem 安装 redis 接口

gem install redis

安装报错：

[root@jp33e503-7-11 cluster]# gem install redisFetching: redis-4.0.0.gem (100%)ERROR:  Error installing redis:        redis requires Ruby version >= 2.2.2.  #提示ruby版本较低  查看现在版本：[root@jp33e503-7-11 cluster]# ruby -vruby 2.0.0p648 (2015-12-16) [x86_64-linux]解决办法：wget https://cache.ruby-lang.org/pub/ruby/2.4/ruby-2.4.1.tar.gztar -xvzf ruby-2.4.1.tar.gz cd ruby-2.4.1./configuremake && make installruby  -v[root@jp33e503-7-11 ~]# ruby  -vruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]

再次执行：

创建集群，确保开放端口

测试集群

在 172.17.7.11:7001 机器上设置一个键值对 testKey--testValue ,因为绑定了 IP ,所以 h 参数不能省略

redis-cli -h 172.17.7.11 -c -p 7001

172.17.7.11:7001> set testkey testvalue-> Redirected to slot [4757] located at 172.17.7.26:7002OK172.17.7.26:7002> get testkey"testvalue"

在 72.17.7.25:7001 上获取 testKey 的值,发现自动定向到 72.17.7.26:7002,说明成功

[root@jp33e503-7-11 ~]# redis-cli -h 172.17.7.25 -c -p 7001 172.17.7.25:7001> get testkey-> Redirected to slot [4757] located at 172.17.7.26:7002"testvalue"

至此，Redis 集群搭建完成

节点命令

#将 ip 和 port 所在的节点添加到集群当中 cluster meet

#从集群中移除 node_id 指定的节点。 cluster forget

#将当前结点设置为 node_id 的 slave（从节点） cluster replicate

#保存节点配置文件 cluster saveconfig

槽命令

#将一个或多个槽（ slot）指派（ assign）给当前节点。 cluster addslots [slot ...]

#移除一个或多个槽对当前节点的指派。 cluster delslots [slot ...]

#移除指派给当前节点的所有槽，让当前节点变成一个没有指派任何槽的节点。 cluster flushslots

#将槽 slot 指派给 node_id 指定的节点，如果槽已经指派给另一个节点，那么先让另一个节点删除该槽>，然后再进行指派。 cluster setslot node

#将本节点的槽 slot 迁移到 node_id 指定的节点中。 cluster setslot migrating

#从 node_id 指定的节点中导入槽 slot 到本节点。 cluster setslot importing

#取消对槽 slot 的导入（ import）或者迁移（ migrate）。 cluster setslot stable

键

#计算键 key 应该被放置在哪个槽上。 cluster keyslot

#返回槽 slot 目前包含的键值对数量。 cluster countkeysinslot

#返回 count 个 slot 槽中的键。 cluster getkeysinslot

脚本

启动节点

首次安装，体验一下过程，官方下载的源码包里面有线程的自动化脚本，安装单个服务和创建集群的，大家可以考虑使用：

脚本位置：redis-4.0.1/utils

[root@ts-100-20 utils]# ls

build-static-symbols.tcl generate-command-help.rb install_server.sh redis_init_script.tpl whatisdoing.sh

cluster_fail_time.tcl graphs lru redis-sha1.rb

corrupt_rdb.c hashtable redis-copy.rb releasetools

create-cluster hyperloglog redis_init_script speed-regression.tcl
