Here are some additional technical details.
I suspect that the problem is with MySQL. I found the mysql directory on the UNIX server. The directory contains a program for performing a test run of MySQL. The program is called mysql-test-run. I executed the program by typing, "./mysql-test-run". This resulted in a failure for something called grant2. The following error message appeared: ""grant2 [ fail ]". Additional details about this failure appeared below the message, and are as follows.
Errors are (from
mysqltest: At line 177: query 'connect
con8,127.0.0.1,root,,test,$MASTER_MYPORT,' failed: 2013: Lost connection
to MySQL server at 'reading initial communication packet', system error: 0
(the last lines may be the most important ones)
Result from queries before failure can be found in r/grant2.log
Aborting: grant2 failed in default mode. To continue, re-run with '--force'.
Stopping All Servers
I attempted to restart MySQL. I went to the directory containing mysql and typed, "mysql restart". That resulted in the error message, "ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (146)".
Again, I do not know whether this is an OJS problem. However, I would appreciate any advice.
It is urgent that I get the website running again.
