Workaround:

1,minion cannot authenticate master, view Minion and master configuration issues, no problem.

Note:

2,minion, the master can be ping through. itself on a machine.

3, test from another minion. No feedback to 60 seconds.

4, according to this hint

[WARNING] Unable to bind socket, error: [Errno] cannot assign requested address
The ports is not available to bind

Adjust the number of ports. Or not, indicating that there is a problem with the error, not port issues.

# echo 16777216 >/proc/sys/net/core/rmem_max
# echo 16777216 >/proc/sys/net/core/wmem_max
# echo "4096 87380 16777216" >/proc/sys/net/ipv4/tcp_rmem
# echo "4096 87380 16777216" >/proc/sys/net/ipv4/tcp_wmem

5 Based on this hint

[WARNING] Unable to bind socket, error: [Errno] cannot assign requested address
The ports is not available to bind

Delete the related run content.

KILLALL-SIGUSR2 Salt-master

Still does not make, indicates the error has the problem, is not carries on the service question.

6 But many times the problem of IP address is indicated. Finally enter Python using the following command

#!/usr/bin/python env
Import socket
MyName = Socket.getfqdn (Socket.gethostname ())
MYADDR = Socket.gethostbyname (myname)
Print "myname=%s"% myname
Print "myaddr=%s"% myaddr

The address of the inverse value, not the address of my machine. It's 10.10.10.10.
While master and Minion are configured with 192.168.10.10


Ifconfig View Machine address is 10.10.10.10 oh ~~~~~~~~~~

Why is it? Because I applied NAT on the Vm,couldstack network on Cloudstack.

Write about the problem decomposition of the Couldstack network in a moment.
