准备好压缩包
一、编译，解压编译过后，在src目录下执行 make install命令
二、在安装目录下创建一个cluster目录，以及7000 7001 7002端口，如果是多台创建的，就在多台上面创建对应的目录
三、把上面编译好的src目录下面的redis-server拷贝到cluster目录下
四、修改redis.conf文件，内容如下
#可选操作，该项设置后台方式运行， daemonize yes
bind 192.168.2.247（需要不同服务器的节点连通，就不能设置为 127.0.0.1，如果是单台的服务器，写为127.0.0.1就行）
protected-mode no（需要不同服务器的节点连通，这个就要设置为 no）
daemonize yes（设置后台运行redis）
cluster-enabled yes
cluster-node-timeout 5000
appendonly yes
修改对应的端口就行，修改完过后，在把对应端口的文件放入到上面的对应目录下面去
五、进入对应的目录，执行下面命令
cd 7000 ../redis-server ./redis.conf
每个端口都执行对应命令，出现以下表示成功
或者执行披萨-ef|grep redis ,也可以查看是否启动成功
Redis的实例全部运行之后，还需要redis-trib.rb工具来完成集群的创建，redis-trib.rb二进制文件在Redis包主目录下的src目录中，运行该工具依赖Ruby环境和gem，因此需要提前安装。
六、安装Ruby
yum -y install ruby rubygems
先查看查看Ruby版本信息
[root@kube-node-1 src]# ruby --version ruby 2.0.0p648 (2015-12-16) [x86_64-linux]
由于centos系统默认支持Ruby版本为2.0.0，因此执行gem install redis命令时会报以下错误。
[root@kube-node-1 src]# gem install redis Fetching: redis-4.0.1.gem (100%) ERROR: Error installing redis: redis requires Ruby version >= 2.2.2.
解决方法是先安装rvm，再升级ruby版本。
七、安装rvm
curl -L get.rvm.io | bash -s stable
如果遇到以下报错，则执行报错中的gpg2 --recv-keys的命令。
[root@kube-node-1 ~]# curl -L get.rvm.io | bash -s stable

执行报错中的gpg2 --recv-keys的命令。

再次执行命令curl -L get.rvm.io | bash -s stable报错。例如
Failed to connect to 2600:3c03::f03c:91ff:fedb:6957: Network is unreachable
请换成如下命令执行
curl -L https://raw.githubusercontent.com/wayneeseguin/rvm/master/binscripts/rvm-installer | bash -s stable
[root@kube-node-1 ~]# curl -L get.rvm.io | bash -s stable

Creating group ‘rvm‘
Installing RVM to /usr/local/rvm/
Installation of RVM in /usr/local/rvm/ is almost complete:
* First you need to add all users that will be using rvm to ‘rvm‘ group,
and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.
* To start using RVM you need to run `source /etc/profile.d/rvm.sh`
in all your open shell windows, in rare cases you need to reopen all shell windows.
以上表示执行成功，
source /usr/local/rvm/scripts/rvm
curl -L get.rvm.io | bash -s stable执行这个命令是报如下错误
查看rvm库中已知的ruby版本
rvm list known
八、升级Ruby
安装ruby rvm install 2.4.0 #使用新版本 rvm use 2.4.0 #移除旧版本 rvm remove 2.0.0 #查看当前版本 ruby --version
例如
[root@kube-node-1 ~]# rvm install 2.4.0
Searching for binary rubies, this might take some time.

[root@kube-node-1 ~]# ruby --version
ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
九、安装gem
[root@kube-node-1 ~]# gem install redis Fetching: redis-4.0.1.gem (100%) Successfully installed redis-4.0.1 Parsing documentation for redis-4.0.1 Installing ri documentation for redis-4.0.1 Done installing documentation for redis after 2 seconds 1 gem installed
十、执行redis-trib.rb命令
cd src #执行redis-trib.rb命令 ./redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 > 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005
redis-trib.rb命令在之前编译的redis下面的src目录下面，
参数create表示创建一个新的集群，--replicas 1表示为每个master创建一个slave。
如果创建成功会显示以下信息
十一、部署结果验证
使用客户端redis-cli二进制访问某个实例，执行set和get的测试。
$ redis-cli -c -p 7000 redis 127.0.0.1:7000> set foo bar -> Redirected to slot [12182] located at 127.0.0.1:7002 OK redis 127.0.0.1:7002> set hello world -> Redirected to slot [866] located at 127.0.0.1:7000 OK redis 127.0.0.1:7000> get foo -> Redirected to slot [12182] located at 127.0.0.1:7002 "bar" redis 127.0.0.1:7000> get hello -> Redirected to slot [866] located at 127.0.0.1:7000 "world"
使用cluster info命令查看集群状态。
127.0.0.1:7000> cluster info cluster_state:ok #集群状态 cluster_slots_assigned:16384 #被分配的槽位数 cluster_slots_ok:16384 #正确分配的槽位 cluster_slots_pfail:0 cluster_slots_fail:0 cluster_known_nodes:6 #当前节点 cluster_size:3 cluster_current_epoch:6 cluster_my_epoch:1 cluster_stats_messages_ping_sent:48273 cluster_stats_messages_pong_sent:49884 cluster_stats_messages_sent:98157 cluster_stats_messages_ping_received:49879 cluster_stats_messages_pong_received:48273 cluster_stats_messages_meet_received:5 cluster_stats_messages_received:98157
使用cluster nodes命令查看节点状态。
127.0.0.1:7000> cluster nodes be2718476eba4e56f696e56b75e67df720b7fc24 127.0.0.1:7002@17002 master - 0 1517303607000 3 connected 10923-16383 13d0c397604a0b2644244c37b666fce83f29faa8 127.0.0.1:7001@17001 master - 0 1517303606000 2 connected 5461-10922 3d02f59b34047486faecc023685379de7b38076c 127.0.0.1:7003@17003 slave 13d0c397604a0b2644244c37b666fce83f29faa8 0 1517303606030 4 connected d5a834d075fd93eefab877c6ebb86efff680650f 127.0.0.1:7000@17000 myself,master - 0 1517303604000 1 connected 0-5460 99c07119a449a703583019f7699e15afa0e41952 127.0.0.1:7005@17005 slave d5a834d075fd93eefab877c6ebb86efff680650f 0 1517303607060 6 connected dedf672f0a75faf37407ac4edd5da23bc4651e25 127.0.0.1:7004@17004 slave be2718476eba4e56f696e56b75e67df720b7fc24 0 1517303608082 5 connected
