docker打包镜像搭建redis集群
从192.168.0.121服务器打包下载镜像
docker save -o redis-cluster-4.0.1.tar ubuntu-redis
镜像下载地址：https://download.csdn.net/download/wxuzero/11038067
在目标服务器载入镜像
docker load --input redis-cluster-4.0.1.tar
查看镜像
docker images
创建启动容器
docker run -it -d --net=host --name=redis-cluster-4.0.1 redis-cluster-4.0.1
进入容器
docker exec -it redis-cluster-4.0.1 /bin/bash
启动各redis节点
/opt/redis-cluster/nodes-7001/redis-4.0.1/src/redis-server /opt/redis-cluster/nodes-7001/redis-4.0.1/redis.conf
/opt/redis-cluster/nodes-7002/redis-4.0.1/src/redis-server /opt/redis-cluster/nodes-7002/redis-4.0.1/redis.conf
/opt/redis-cluster/nodes-7003/redis-4.0.1/src/redis-server /opt/redis-cluster/nodes-7003/redis-4.0.1/redis.conf
/opt/redis-cluster/nodes-7004/redis-4.0.1/src/redis-server /opt/redis-cluster/nodes-7004/redis-4.0.1/redis.conf
/opt/redis-cluster/nodes-7005/redis-4.0.1/src/redis-server /opt/redis-cluster/nodes-7005/redis-4.0.1/redis.conf
/opt/redis-cluster/nodes-7006/redis-4.0.1/src/redis-server /opt/redis-cluster/nodes-7006/redis-4.0.1/redis.conf
查看redis启动情况
ps -ef|grep redis
进入到/opt/redis-cluster/nodes-7001/redis-4.0.1/src目录启动集群（注IP192.168.0.121改为对应服务器IP）
redis-trib.rb create --replicas 1 192.168.0.121:7001 192.168.0.121:7002 192.168.0.121:7003 192.168.0.121:7004 192.168.0.121:7005 192.168.0.121:7006
测试集群搭建成功
cd /opt/redis-cluster/nodes-7001/redis-4.0.1/src
./redis-cli -p 7001 -c
127.0.0.1:7001> set key1 1
-> Redirected to slot [9189] located at 192.168.0.121:7002
OK
192.168.0.121:7002> get key1
"1"
192.168.0.121:7002>
# ./redis-cli -p 7002 -c
127.0.0.1:7002> get key1
"1"
# ./redis-cli -p 7003 -c
127.0.0.1:7003> get key1
-> Redirected to slot [9189] located at 192.168.0.121:7002
"1"
192.168.0.121:7002>
退出容器
附：
启动各节点脚本
vim start-all.sh
cd /opt/redis-cluster/nodes-7001/redis-4.0.1/src/
./redis-server /opt/redis-cluster/nodes-7001/redis-4.0.1/redis.conf
cd /opt/redis-cluster/nodes-7002/redis-4.0.1/src/
./redis-server /opt/redis-cluster/nodes-7002/redis-4.0.1/redis.conf
cd /opt/redis-cluster/nodes-7003/redis-4.0.1/src/
./redis-server /opt/redis-cluster/nodes-7003/redis-4.0.1/redis.conf
cd /opt/redis-cluster/nodes-7004/redis-4.0.1/src/
./redis-server /opt/redis-cluster/nodes-7004/redis-4.0.1/redis.conf
cd /opt/redis-cluster/nodes-7005/redis-4.0.1/src/
./redis-server /opt/redis-cluster/nodes-7005/redis-4.0.1/redis.conf
cd /opt/redis-cluster/nodes-7006/redis-4.0.1/src/
./redis-server /opt/redis-cluster/nodes-7006/redis-4.0.1/redis.conf
关闭集群脚本
vim shutdown-all.sh
cd /opt/redis-cluster/nodes-7001/redis-4.0.1/src
./redis-cli -p 7001 shutdown
./redis-cli -p 7002 shutdown
./redis-cli -p 7003 shutdown
./redis-cli -p 7004 shutdown
./redis-cli -p 7005 shutdown
./redis-cli -p 7006 shutdown
