上节主要演示了redis单节点的安装部署，对于数据量更大的服务可以安装redis-cluster进行处理
1. 安装ruby
yum install ruby ruby-devel rubygems rpm-build -y rpm -qa|grep ruby ruby -v
2.安装redis-cluster
gem install redis --version 3.2.1 gem list
3.到redis源码目录找到集群创建工具
/bin/cp /server/tools/redis-3.2.10/src/redis-trib.rb /usr/local/redis/bin/
4.创建redis-cluster集群节点
(1)创建节点目录，修改配置文件
[root@redis-server tools]# mkdir -p /usr/local/redis/redis-cluster/{7001,7002,7003}
cluster-enabled yes
cluster-config-file /usr/local/redis/redis-cluster/6379/nodes-6379.conf
cluster-node-timeout 5000
appendonly yes
[root@redis-server tools]# sh -x add_redis-cluster-port_rc.sh 8001 8002 8003 + echo '------ Start Create redis-cluster ------' ------ Start Create redis-cluster ------ + redisport1=8001 + redisport2=8002 + redisport3=8003 + redis_path=/usr/local/redis + redis_cluster_path=/usr/local/redis/redis-cluster ++ grep -v 127.0.0.1 ++ grep -v inet6 ++ grep inet ++ awk '{print $2}' ++ /sbin/ifconfig -a ++ tr -d addr: + localIP=192.168.1.71 + '[' -z 8001 ']' + echo 'The redis-port is 8001' The redis-port is 8001 + '[' -z 8002 ']' + echo 'The redis-port is 8002' The redis-port is 8002 + '[' -z 8003 ']' + echo 'The redis-port is 8003' The redis-port is 8003 + echo /usr/local/redis/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin /usr/local/redis/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin + sleep 1 + mkdir -p /usr/local/redis/redis-cluster/8001 /usr/local/redis/redis-cluster/8002 /usr/local/redis/redis-cluster/8003 + cd /server/tools/ + /bin/cp democonf_redis-cluster_6379.conf /usr/local/redis/redis-cluster/8001/conf-8001.conf + sed -i s#6379#8001#g /usr/local/redis/redis-cluster/8001/conf-8001.conf + /bin/cp democonf_redis-cluster_6379.conf /usr/local/redis/redis-cluster/8002/conf-8002.conf + sed -i s#6379#8002#g /usr/local/redis/redis-cluster/8002/conf-8002.conf + /bin/cp democonf_redis-cluster_6379.conf /usr/local/redis/redis-cluster/8003/conf-8003.conf + sed -i s#6379#8003#g /usr/local/redis/redis-cluster/8003/conf-8003.conf + tree /usr/local/redis/redis-cluster /usr/local/redis/redis-cluster ├── 8001 │ └── conf-8001.conf ├── 8002 │ └── conf-8002.conf └── 8003 └── conf-8003.conf 3 directories, 3 files + echo '------ Start redis-cluster nodes ------' ------ Start redis-cluster nodes ------ + sleep 1 + /usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8001/conf-8001.conf + /usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8002/conf-8002.conf + /usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8003/conf-8003.conf ++ date +%F + echo '# redis-cluster-port for 8001,8002,8003 in 2017-09-21' + echo '/usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8001/conf-8001.conf' + echo '/usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8002/conf-8002.conf' + echo '/usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8003/conf-8003.conf' + tail -4 /etc/rc.local tail: 无法使用 inotify 机制，回归为 polling 机制 # redis-cluster-port for 8001,8002,8003 in 2017-09-21 /usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8001/conf-8001.conf /usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8002/conf-8002.conf /usr/local/redis/bin/redis-server /usr/local/redis/redis-cluster/8003/conf-8003.conf + echo '------ Create redis-cluster ------' ------ Create redis-cluster ------ + sleep 1 + /usr/local/redis/bin/redis-trib.rb create --replicas 0 192.168.1.71:8001 192.168.1.71:8002 192.168.1.71:8003 >>> Creating cluster Connecting to node 192.168.1.71:8001: OK Connecting to node 192.168.1.71:8002: OK Connecting to node 192.168.1.71:8003: OK >>> Performing hash slots allocation on 3 nodes...
