集群部署

安装集群

for port in $(seq 7001 7006); \
do \
mkdir -p /mydata/redis/node-${port}/conf
touch /mydata/redis/node-${port}/conf/redis.conf
cat << EOF >/mydata/redis/node-${port}/conf/redis.conf
port ${port}
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 192.168.56.157
cluster-announce-port ${port}
cluster-announce-bus-port 1${port}
appendonly yes
EOF
docker run -p ${port}:${port} -p 1${port}:1${port} --name redis-${port} \
-v /mydata/redis/node-${port}/data:/data \
-v /mydata/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf \
-d redis:5.0.7 redis-server /etc/redis/redis.conf; \
done

docker stop $(docker ps -a |grep redis-700 | awk ‘{ print $1}’)
docker rm $(docker ps -a |grep redis-700 | awk ‘{ print $1}’)
docker exec -it redis-7001 /bin/bash
redis-cli --cluster create 192.168.56.157:7001 192.168.56.157:7002 192.168.56.157:7003 192.168.56.157:7004 192.168.56.157:7005 192.168.56.157:7006 --cluster-replicas 1

测试

  随便进入某个redis 容器
  docker exec -it redis-7002 /bin/bash
  使用redis-cli 的cluster 方式进行连接
  redis-cli -c -h 192.168.56.10 -p 7006
  cluster info； 获取集群信息
  cluster nodes；获取集群节点
  Get/Set 命令测试，将会重定向
  节点宕机，slave 会自动提升为master，master 开启后变为slave
