Redis 3.0 Cluster集群配置

安装环境依赖

安装gcc：yum install gcc

安装zlib：yum install zib

安装ruby：yum install ruby

安装rubygems：yum install rubygems

安装ruby的redis驱动：gem install redis

安装redis

参考：http://www.cnblogs.com/rwxwsblog/p/5285732.html

修改配置文件

vi 6379.conf

port=6379

pidfile /var/run/redis_6379.pid

logfile /var/log/redis_6379.log

daemonize=yes

cluster-enabled yes

cluster-config-file nodes-6379.conf

cluster-node-timeout 15000

appendonly yes

dir /var/lib/redis/6379

复制相应的配置文件并按上述配置文件修改相应的配置（注意端口和路径）

cp 6379.conf 6380.conf

cp 6379.conf 6381.conf

cp 6379.conf 6382.conf

cp 6379.conf 6383.conf

cp 6379.conf 6384.conf

cp 6379.conf 6385.conf

依次修改相应的配置文件6380.conf、6381.conf、6382.conf、6383.conf、6384.conf、6385.conf

如：vi 6380.conf

批量替换端口:%s/6379/6380/g并保存

创建数据文件目录

mkdir -p /var/lib/redis/6380 /var/lib/redis/6381 /var/lib/redis/6382 /var/lib/redis/6383 /var/lib/redis/6384 /var/lib/redis/6385

创建集群

安装并配置完后6379端口的redis实例需要重启，否则会报错

创建前需要分别启动redis实例

cp redis-3.0.7/src/redis-trib.rb /usr/local/bin/

redis-trib.rb create --replicas 1 127.0.0.1:6379 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384 127.0.0.1:6385

创建集群实例及异常情况

[root@cas ~]# redis-trib.rb create --replicas 1  127.0.0.1:6379 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384 127.0.0.1:6385

添加节点

add-node的使用方法为new_host:new_port existing_host:existing_port，前面是新添加的节点信息，后面是已存在的节点信息

redis-trib.rb add-node 192.168.3.61:6379 192.168.3.88:6379
