Redis 3.2.8集群+Sentinel部署

Redis3.2.8集群搭建

采用官方推荐的三主三从分片方案，本例中所有节点部署在一台主机上。

软件安装:

tar zxvf redis-3.2.8.tar.gz

cd  redis-3.2.8

make

make install 

mkdir redis-cluster

根据端口号，创建六个节点

mkdir redis-cluser/6379、6380、6381、6382、6383、6384

拷贝配置文件到各个节点:

cp redis.conf  redis-cluser/6379、6380、6381、6382、6383、6384

修改配置文件:

vim redis-cluser/6379、6380、6381、6382、6383、6384/redis.conf

port    ＃端口号

pidfile ＃pid文件

logfile "/data/local/redis-cluster/6379/redis.log"  #日志文件

cluster-enabled yes  ＃开启集群模式

cluster-config-file nodes-6380.conf

若需要远程连接，需要注释掉bind 127.0.0.1 改为　bind 0.0.0.0

启动:redis-server 6379、6380、81、82、83、84/redis.conf

 

安装redis-trib.rb工具:

安装依赖组件:yum install ruby ruby-devel rubygems rpm-build

gem install redis

# 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

创建集群，每个节点有一个从节点

注:使用redis-trib.rb create --replicas 1 这种方式创建主从集群的前提是，至少有6个节点，3主3从

 sentinel

sentinel.conf:

注释默认相关配置，添加master监控:

sentinel monitor master1 127.0.0.1 6379 2
sentinel down-after-milliseconds master1 60000
sentinel failover-timeout master1 180000
sentinel parallel-syncs master1 1

sentinel down-after-milliseconds master2 60000

sentinel monitor master3 127.0.0.1 6381 2
sentinel down-after-milliseconds master3 60000
sentinel failover-timeout master3 180000
sentinel parallel-syncs master3 1

 ＃redis-server sentinel.conf --sentinel &

配置后台启动:

sentinel.conf，添加:

daemonize yes

启动:

#redis-server sentinel.conf --sentinel
