When starting infobright, I can't get up all the time. After seeing the log, the following error occurs:

141128 12:18:20 [ERROR] / usr/local/infobright-4.5.0-x86_64/bin/mysqld: Can't find file:'. / mysql/host.frm' (errno: 13)

141128 12:18:20 [ERROR] Fatal error: Can't open and lock privilege tables: Can't find file:'. / mysql/host.frm' (errno: 13)

At that time, it was also strange that there was such a path as / mysql/. I checked several times, but I still couldn't find it. Later, du Niang said that authority was involved, but because she was not familiar with it, she did not know where the authority was.

So check the infobright engine log:

2014-11-28 12:37:50 No LicenseFile entry in ini file. Using default path.

2014-11-28 12:37:50 License file path: / usr/local/infobright-4.5.0-x86_64/iblicense-xulong_deng-174744303-IEE.lic

2014-11-28 12:37:50 Brighthouse engine started.

From here I can be sure that the basedir permission of infobright is correct, so the only thing left is the datadir directory.

Go to datadir and see that it is really a permission problem:

So you can start infobright successfully by changing the permissions.

At this point, I believe you have a deeper understanding of "meeting Can't find file when starting infobright:'. / mysql/host.frm' how to solve", might as well come to the actual operation!
