redis报错解决

1、Connecting to node 127.0.0.17000 [ERR] Sorry, can't connect to node 192.168.1.917000

Connecting to node 127.0.0.1:7000: [ERR] Sorry, can't connect to node 192.168.1.91:7001

这个错误的话那就查看下你6个端口是否都启动了，没启动的话会报上面的错误

2、error) NOAUTH Authentication required.

出现认证问题，应该是设置了认证密码，输入密码既可以

方法一、

127.0.0.1:6379> auth "yourpassword"
例如密码是‘root’,当出现认证问题时候，输入“auth ‘root’”即可

127.0.0.1:6379> set name "fish"
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth "root"
127.0.0.1:7000> auth joinu_1233
OK

方法二、

[root@bogon conf]# redis-cli -c -p 7000 -a joinu_1233
127.0.0.1:7000> set name fish
-> Redirected to slot [5798] located at 127.0.0.1:7002
OK
127.0.0.1:7002>

3、redis停止报错

Redis 停止时出现： (error) NOAUTH Authentication required.
复制代码
root@iZ25gdzs0p8Z:~# /etc/init.d/redis_6379 stop
Stopping ...
(error) NOAUTH Authentication required.
Waiting for Redis to shutdown ...
Waiting for Redis to shutdown ...

解决：

停止时要加登陆时密码。
[root@bogon conf]# redis-cli -c -p 7000 -a joinu_1233 shutdown
[root@bogon conf]# redis-cli -c -p 7000
Could not connect to Redis at 127.0.0.1:7000: Connection refused
Could not connect to Redis at 127.0.0.1:7000: Connection refused
not connected>

4、redis远程连接以及注意事项

[root@mch ~]# ps -ef | grep redis
　　root 2175 1 0 08:15 ? 00:00:05 /usr/local/bin/redis-server *:6379

　　/usr/local/bin/redis-server *:6379 中通过"*"就可以看出此时是允许所有的ip连接登录到这台redis服务上。

redis-cli -h 192.168.43.75 -p 6379 -a ilanniredis

5、reidis集群报错

[root@localhost src]# ./redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.3:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005
报错：[ERR] Sorry, can't connect to node 172.0.0.0:7000
解决：重启centos系统,亲测，网上的都试过，没有用

6、在k8s里面连接redis报错

# redis-cli -h 10.104.130.187
Could not connect to Redis at 10.104.130.187:6379: No route to host
Could not connect to Redis at 10.104.130.187:6379: No route to host

解决：

把endpoint 的地址改成内网地址即可

7、k8s中连接redis错误： java.lang.NumberFormatException: For input string: "6379@16379"

把java配置文件中的端口写死，写成 6379
