在配置文件配置redis后，報如下錯誤
msg="failed to put to redis" name=store.index-cache-write.redis err="EXECABORT Transaction discarded because of previous errors."
原因：redis多個地址用逗號分割椭懊，如果只配置一個地址箕戳，而我們的redis又是cluster模式的話响疚，會報改錯
解決辦法：如果是集群版redis确憨，寫多個redis地址即可
// NewUniversalClient returns a new multi client. The type of the returned client depends
// on the following conditions:
//
// 1. If the MasterName option is specified, a sentinel-backed FailoverClient is returned.
// 2. if the number of Addrs is two or more, a ClusterClient is returned.
// 3. Otherwise, a single-node Client is returned.
func NewUniversalClient(opts *UniversalOptions) UniversalClient {
if opts.MasterName != "" {
return NewFailoverClient(opts.Failover())
} else if len(opts.Addrs) > 1 {
return NewClusterClient(opts.Cluster())
}
return NewClient(opts.Simple())
}
