生产环境中无法从redis里面读取数据

Java程序里面写了使用redis缓存，但是死活调用不了redis里面的数据，redis里面有缓存

首先，登录查看redis是否可以get数据，发现只有本地

[root@redis_test ~]# ss -lntup|grep redis           #查看端口是否起来 tcp    LISTEN     0      128                    *:6379                  *:*      users:(("redis-server",2248,4)) [root@redis_test ~]# redis-cli         #登录 redis 127.0.0.1:6379> set dd "haha"           #set值看能否取到 OK   redis 127.0.0.1:6379> get dd "haha"

[root@redis_test ~]# redis-cli  redis 127.0.0.1:6379> CLIENT LIST       #返回所有连接到服务器的客户端信息和统计数据 addr=127.0.0.1:33955 fd=5 name= age=20 idle=0 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=client redis 127.0.0.1:6379> CLIENT LIST addr=127.0.0.1:33955 fd=5 name= age=24 idle=0 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=client

2.查看selinux和防火墙是否关闭

root@redis_test ~]# getenforce        Disabled [root@redis_test ~]# service  iptables status Table: filter

3.关闭防火墙再看

[root@redis_test ~]# service  iptables stop iptables: Setting chains to policy ACCEPT: filter          [  OK  ] iptables: Flushing firewall rules:                         [  OK  ] iptables: Unloading modules:                               [  OK  ] [root@redis_test ~]# redis-cli  redis 127.0.0.1:6379> CLIENT LIST addr=127.0.0.1:33956 fd=5 name= age=2 idle=0 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=client redis 127.0.0.1:6379> CLIENT LIST addr=127.0.0.1:33956 fd=5 name= age=3 idle=0 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=client redis 127.0.0.1:6379> CLIENT LIST addr=127.0.0.1:33956 fd=5 name= age=15 idle=0 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=client addr=10.0.0.106:60182 fd=6 name= age=5 idle=5 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=0 obl=0 oll=0 omem=0 events=r cmd=ping

4.总结

果然是防火墙没关的问题。
