This occurred after an update was run with Yum. Two MySQL versions were present and the errmsg.sys file from the old or “bad” version was used.
I was able to resolve this by tracking down the correct errmsg.sys file for the “good” version of MySQL. Full instructions for this can be found below.
Full error message:
120327 9:18:48 [ERROR] Error message file ‘/usr/share/mysql/english/errmsg.sys’ had only 481 error messages,
but it should contain at least 641 error messages.
Check that the above file is the right version for this program!
/usr/libexec/mysqld: Unknown error 1146
120327 9:18:48 [ERROR] Can’t open the mysql.plugin table. Please run mysql_upgrade to create it.
1. Determine the correct version of MySQL:
yum list installed | grep mysql
mysql.i386 5.0.95-1.el5_7.1 installed mysql.x86_64 5.1.58-jason.1 installed
2. Find the tar.gz installer file for your specific version of MySQL. Change the version in the following URL as needed:
The example output above confirms there are two versions installed. The newer one is the “correct” version (5.1.58). You are looking for the .tar.gz file with no additional details in the name, for example “mysql-5.1.58.tar.gz”.
3. Extract the newly downloaded install files:
tar -zxf mysql-5.1.58.tar.gz
4. Make a copy of the old errmsg.sys file just in case:
mv /usr/share/mysql/english/errmsg.sys /usr/share/mysql/english/errmsg.sys.old
5. Copy the new errmsg.sys file to this same location:
cp mysql-5.1.58/sql/share/english/errmsg.sys /usr/share/mysql/english/errmsg.sys
6. Attempt to start the MySQL service again:
If this process does not work the best option may be to uninstall and reinstall MySQL (after backing everything up of course).
