When the linux server nginx builds load balancing as a cluster, the file cannot be uploaded, and the log 411 error is viewed;

Nginx configures the cluster correctly, but the access to the file server cannot be uploaded. Checking the log of nignx, the error exception code is 411.

Need to download the chunk module

But after the high version, it is directly supported 

Directly download and install nginx1.8 version or later, the problem is solved
