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

#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

#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

#当有2w 条keys 数据被改变时，8000 秒刷新到disk 一次
save 8000 20000
#当dump .rdb 数据库的时候是否压缩数据对象
rdbcompression yes
#dump 持久化数据保存的文件名

使用默认配置文件启动redis会报错的，需要修改maxmemory这一项，注意单位时字节
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
