香港云服务器Redis集群水平扩容的示例:
1.加入新的master:
mkdir -p /var/redis/7007
修改配置文件信息 /etc/redis/7007.conf
port 7007
cluster-enabled yes
cluster-config-file /etc/redis-cluster/node-7007.conf
cluster-node-timeout 15000
daemonize yes
pidfile /var/run/redis_7007.pid
dir /var/redis/7007
logfile /var/log/redis/7007.log
bind 192.168.31.227
appendonly yes
启动脚本 /etc/init.d/redis_7007
redis-trib.rb add-node 192.168.1.107:7007 192.168.1.107:7001
redis-trib check 192.168.1.107:7001
2.reshared数据,slot从一些master移动到新的master,达到扩容减轻其他主节点的压力,代码:
redis-trib.rb reshared 192.168.1.107:7001
