看到这个问题解决办法如下

检查网络

ping远程试试

telnet

telnet ip port

检查主机端口白名单

netstate -ntlp

检查redis对外密码及配置

查看配置源
vim redis.conf
redis配置文件含义
#是否作为守护进程运行
daemonize no
#Redis 默认监听端口
port 6379
#客户端闲置多少秒后，断开连接
timeout 300
#日志显示级别
loglevel verbose
#指定日志输出的文件名，也可指定到标准输出端口
logfile redis.log
#设置数据库的数量，默认最大是16,默认连接的数据库是0，可以通过select N 来连接不同的数据库
databases 32
#Dump持久化策略
#当有一条Keys 数据被改变是，1200 秒刷新到disk 一次
#save 1200 1
#当有10 条Keys 数据被改变时，600 秒刷新到disk 一次

maxmemory 223345100
如果需要设置连接密码，就修改requirepass，设为自己的密码。
requirepass mypassword
