redis-master name=redis-master name=redis-master 10.254.154.90 6379/TCP
redis-slave name=redis-slave name=redis-slave 10.254.159.145 6379/TCP
发现redis-master是在10.254.154.90上，登录到centos2上，执行iptables-save，发现其中有这样一条规则
-A KUBE-PORTALS-HOST -d 10.254.154.90/32 -p tcp -m comment –comment “default/redis-master:” -m tcp –dport 6379 -j DNAT –to-destination 192.168.1.112:49038
说明，centos2本机的49038端口映射到master container内的6379了，当然我们就能执行在本机访问redis了
[root@centos2 yum.repos.d]# redis-cli -p 49038
127.0.0.1:49038> set a b
OK
127.0.0.1:49038> get a
"b"
8、使用curl简单测试
提交数据
curl “localhost:8000/index.php?cmd=set&key=messages&value=jay_sais_hi”
查询数据
curl “localhost:8000/index.php?cmd=get&key=messages”
