Redis Cluster 4.0.9集群搭建步骤：
yum install -y gcc g++ gcc-c++ make openssl
cd redis-4.0.9
make
mkdir -p /usr/local/redis-4.0.9
make install PREFIX=/usr/local/redis-4.0.9
mkdir -p /usr/local/ruby-2.4.0
cd ruby-2.4.0
./configure -prefix=/usr/local/ruby-2.4.0
make && make install
yum install rubygems
gem install -l redis-3.3.3.gem
gem list -- check redis gem
vi /etc/profile
source /etc/profile
export PATH=/usr/local/ruby-2.4.0/bin/:$PATH
配置password
vi /usr/local/ruby-2.4.0/lib/ruby/gems/2.4.0/gems/redis-3.3.3/lib/redis/client.rb
在每台服务器启动redis：
/usr/local/redis-4.0.9/bin/redis-server /u01/redis/2002/conf/redis_2002.conf
/usr/local/redis-4.0.9/bin/redis-server /u01/redis/3003/conf/redis_3003.conf
redis-trib.rb create --replicas 1 192.168.11.11:2002 192.168.11.11:3003 192.168.11.12:2002 192.168.11.12:3003 192.168.11.13:2002 192.168.11.13:3003
查看集群关系
redis-cli -h 192.168.11.11 -p 2002 -c -a "yoon" cluster nodes
查看redis-cluster集群关系
redis-cli -h 192.168.11.11 -p 2002 -c cluster slots | xargs -n8 | awk '{print $3":"$4"->"$6":"$7}' | sort -nk2 -t ':' | uniq
