why nginx worker process listen in port 80, not master process?

[Zhengyu Pan]

In my node, Every network namespace has own nginx process.

when i use netstat command to get which nginx process are listening in port 80? I found that some nginx worker process are listening 80 port. Some nginx master process are listening port 80. In my understanding ,it should be that nginx master process will listen port 80? Why happens that worker process listen port 80? Is it about reload?

  [root at node2 ~]# for i in `ip netns |grep lbaas| awk '{print $1}'`; do ip netns exec $i netstat -atnp |grep nginx;done
