redis5.0集群(三主三从)

进入目录

cd /usr01/admin/redis

解压

tar zxvf redis-5.0.8.tar.gz

进入redis目录

cd redis-5.0.8/

指定内存管理

make MALLOC=libc

make && make install

创建 redis_cluster文件夹。redis_cluster下面创建master、slave文件夹，并在文件夹下添加redis.conf

master下的redis.conf

port 6379
cluster-enabled yes
cluster-config-file "nodes-6379.conf"
logfile "redis-server-6379.log"
dbfilename "dump-6379.rdb"
daemonize yes
bind 172.29.128.70
protected-mode no
supervised no
pidfile /run/redis_6379.pid
dir /usr01/admin/redis_cluster/master

slave下的redis.conf

port 6381
cluster-enabled yes
cluster-config-file "nodes-6381.conf"
logfile "redis-server-6381.log"
dbfilename "dump-6381.rdb"
daemonize yes
bind 172.29.128.70
protected-mode no
supervised no
pidfile /run/redis_6381.pid
dir /usr01/admin/redis_cluster/slave

(其他机器也一样 主要是端口和ip做修改)

启动master、slave的conf

/usr01/admin/redis-5.0.8/src/redis-server /usr01/admin/redis_cluster/master/redis.conf

/usr01/admin/redis-5.0.8/src/redis-server /usr01/admin/redis_cluster/slave/redis.conf

查看redis进程

netstat -tunpl | grep redis

进入任意一个节点，执行以下指令创建集群

/usr01/admin/redis-5.0.8/src/redis-cli  --cluster create 172.29.128.69:6379 172.29.128.69:6381 172.29.128.70:6379 172.29.128.70:6381 172.29.128.71:6379 172.29.128.71:6381  --cluster-replicas 1

结果：

Adding replica 172.29.128.70:6381 to 172.29.128.69:6379
Adding replica 172.29.128.71:6381 to 172.29.128.70:6379

查看集群状态

/usr01/admin/redis-5.0.8/src/redis-cli --cluster check 172.29.128.69:6379

客户端以集群模式连接

/usr01/admin/redis-5.0.8/src/redis-cli  -h 172.29.128.69 -p 6379 -c
