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)

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:

[email protected]:~/hproj/redis-3.0/cluster$ ps -ef | grep 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。

重启Linux防火墙 
[[email protected] 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:
