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

這個錯誤的話那就檢視下你6個埠是否都啟動了，沒啟動的話會報上面的錯誤

2、error) NOAUTH Authentication required.

出現認證問題，應該是設定了認證密碼，輸入密碼既可以

方法一、

127.0.0.1:6379> auth "yourpassword"
例如密碼是‘root’,當出現認證問題時候，輸入“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、

[[email protected] 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停止報錯

Redis 停止時出現： (error) NOAUTH Authentication required.
複製程式碼
[email protected]:~# /etc/init.d/redis_6379 stop
Stopping ...
(error) NOAUTH Authentication required.
Waiting for Redis to shutdown ...
Waiting for Redis to shutdown ...

解決：

停止時要加登陸時密碼。
[[email protected] conf]# redis-cli -c -p 7000 -a joinu_1233 shutdown
[[email protected] 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遠端連線以及注意事項

[[email protected] ~]# 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 中通過"*"就可以看出此時是允許所有的ip連線登入到這臺redis服務上。

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

5、reidis叢集報錯

[[email protected] 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
報錯：[ERR] Sorry, can't connect to node 172.0.0.0:7000
解決：重啟centos系統,親測，網上的都試過，沒有用

6、在k8s裡面連線redis報錯

# 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

解決：

把endpoint 的地址改成內網地址即可

7、k8s中連線redis錯誤： java.lang.NumberFormatException: For input string: "[email protected]"

把java配置檔案中的埠寫死，寫成 6379
