Golang multithreading is easy to use, but sometimes you need to lock the data to prevent data from being changed by other threads. Then the mutex under the sync package is very useful.
A mutex is a mutex. Can be part of a struct so that the struct prevents the data from being changed by multithreading.
Here's an example:

Background introduction:At present, we have more than 200 front-end servers online, each time we release new applications, we put the packages on a dedicated push server, and all the front-end servers are automatically synced through rsync. But with the number of front-end servers increasing, the bandwidth of the push server has become a bottleneck.The BitTorrent sync is a solution. At the same time, its cross-platform support is also very good, wheth
