RedisCommandExecutionException: READONLY You can‘t write against a read only replica.

RedisCommandExecutionException: READONLY You can‘t write against a read only replica.

集成springboot-mysql-redis时报错: RedisCommandExecutionException: READONLY You can't write against a read only replica.

 如下: 

原因: 因为连接的是从节点，从节点只有读的权限，没有写的权限

 解决方法: 

一: redis集群时, 连接的是slave, 修改redis.conf配置为master

二. 不修改slave角色, 在redis文件添加这个命令:  修改配置文件的slave-read-only为no， 那么从节点也就可以进行写的操作了，代码不会报错
