RedisDesktopManager无法远程连接Redis解决方法 - 好文

Linux环境：ubuntu16.04
Redis服务端版本：3.2.6
Redis客户端下载链接：https://redisdesktop.com/download

Ubuntu16.04安装Redis教程，可参考我上篇文章：Ubuntu 16.04下Redis集群部署
<http://blog.csdn.net/hyl999/article/details/79552348>
Redis-3.2.6官网tar.gz下载地址：wget
http://download.redis.io/releases/redis-3.2.6.tar.gz
<http://download.redis.io/releases/redis-3.2.6.tar.gz>

下载RedisDesktopManager客户端，输入服务器IP地址，端口（缺省值：6379）；点击 “连接测试” 按钮测试连接，连接失败！

什么问题呢？原因是Redis默认只支持本地链接，输入进程命令查看得知（127.0.0.1:7000）

wl@ubuntu:~/hproj/redis-3.0/redis-3.2.6/src$ ./redis-cli shutdown

把集群的redis全部kill命令全部kill掉，问题解决：编辑redis.conf配置文件；注释掉61行本地链接限制以及80行配置修改为no

61 # bind 127.0.0.1
80 protected-mode no

读取最新配置文件并重启，查看Redis进程情况！都开放IP链接权限了，怎么还是127.0.0.1:6379！！再查看进程情况：

wl@ubuntu:~/hproj/redis-3.0/cluster$ ./redis-start.sh
wl@ubuntu:~/hproj/redis-3.0/cluster$ ps -ef | grep redis
wl 14200 1416 0 14:00 ? 00:00:00

wl 14225 8680 0 14:01 pts/21 00:00:00 grep --color=auto redis

哇塞，*.7000，这意味着已经成功开放IP访问权限了。万事俱备，只欠点击RedisDesktopManager客户端测试链接按钮了。

防火墙问题

编辑Linux防火墙
[root@Karle src]# vi /etc/sysconfig/iptables
加入防火墙规则：-A INPUT -m state –state NEW -m tcp -p tcp –dport 6379 -j ACCEPT
[root@Karle src]# service iptables status 表格：filter Chain INPUT (policy

重启Linux防火墙
[root@Karle src]# service iptables restart

点击 “测试连接” 按钮测试连接，显示 “连接Redis 服务器成功”，问题解决了。

点击 "好" 按钮，进行操作，出现如下：
