stay https://blog.csdn.net/zly_ On the basis of this blog post 9117 / article / details / 83349778, we found another error when starting redis. The error content is as follows

11045:M 24 Oct 2018 19:26:52.323 # Unrecoverable error: corrupted cluster config file.The literal meaning is a damaged cluster configuration. Similarly, find the corresponding error throw point in the source code and find the following information

fmterr:

}According to the source code interpretation found that we did not build nodes.conf By default, this method returns a C_ Err, and then the caller clusterinit function creates a new file and a cluster. The overall code of clusterloadconfig function is as follows. But now I found this document and read it to prove it wrong redis.conf There is an error in the configuration file. After searching the configuration file, it is found that the parameter of cluster config file is configured incorrectly, and it is changed to cluster config file nodes.conf Problem solving.
/* Load the cluster config from 'filename'.
*
* If the file does not exist or is zero-length (this may happen because
* when we lock the nodes.conf file, we create a zero-length one for the
