Docker 构建 redis 集群

安装docker

1、yum install docker

方法一：

1、 docker pull redis

2、docker run -d --name redis-1 -p 7001:6379 redis

3、docker inspect redis-1 | grep IPA

"SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAMConfig": null,
                    "IPAddress": "172.17.0.2",

4、启动slave

docker run -d --name redis-2 -p 7002:6379 redis redis-server --slaveof 172.17.0.2 6379
docker run -d --name redis-3 -p 7003:6379 redis redis-server --slaveof 172.17.0.2 6379

5、验证：

redis-cli -h 127.0.0.1 -p 7001
127.0.0.1:7001> get key
"hello"
127.0.0.1:7001> exit
redis-cli -h 127.0.0.1 -p 7002
127.0.0.1:7002> get key
"hello"
127.0.0.1:7002> exit
redis-cli -h 127.0.0.1 -p 7003
127.0.0.1:7003> get key
"hello"
127.0.0.1:7003> exit
