遇到的問題如下：

解決方法：
1，minion 無法認證 master, 查看minion 和master 配置問題，沒有問題.
注：
2，minion , master 之間可以ping 通。本身在一臺機器上。
3，從另一個minion進行測試。到60秒沒有反饋。
4，根據這個提示
[WARNING ] Unable to bind socket, error: [Errno 99] Cannot assign requested address
The ports are not available to bind
調整端口數量。還是不好使，說明報錯有問題，不是端口問題。
# 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 根據這個提示
[WARNING ] Unable to bind socket, error: [Errno 99] Cannot assign requested address
The ports are not available to bind
刪除相關運行內容。
killall -SIGUSR2 salt-master
還是不好使，說明報錯有問題，不是進行服務問題。
6 但是多次表明是ip地址的問題。最後進入python使用以下命令
#!/usr/bin/python env
import socket
myname = socket.getfqdn(socket.gethostname())
myaddr = socket.gethostbyname(myname)
print"myname= %s"% myname
print"myaddr= %s"% myaddr
反回值的地址，不是我機器地址。是10.10.10.10
而master 和minion配置的是192.168.10.10
ifconfig 查看機器地址爲10.10.10.10 哦~~~~~~~~~~
爲什麼呢？因爲我應用的是cloudstack上的VM，couldstack網絡做了nat .
一會兒再寫一下couldstack網絡的問題分解。
