有一台基于CentOS 7 下的DirectAdmin自动获取license失败，大概错误提示：
License check failure See the Debug Guide
Reason: transient licence check failure: incompatible version, please upgrade DirectAdmin
Current Server Time:
I have corrected the OS and version and client area, and now it shoud be correct.
and I have try to run getLicense, but it still shows this error.
一、SSH执行
/usr/local/directadmin/scripts/getDA.sh current
即可。
