Ric Posted May 5, 2006 Report Share Posted May 5, 2006 I have mentioned the incompatibility between MySQL 4 and 5 this shows you how to downgrade UniServer 3.3 from MySQL 5 to MySQL 4. The process is relatively simple. 1) You need to work on clean copies of UniServer 3.2a and 3.3 download these and save both files into the same folder. 2) Unzip both files (no need to specify a folder) into the current folder. 3) Within UniServer3_3 rename database folder mysql we need this later. Rename this folder: UniServer3_3/ Uniform Server /diskw/user/local/mysql To: UniServer3_3/ Uniform Server /diskw/user/local/mysql_old 4) From UniServer3_2a copy the mysql folder and all its content to UniServer3_3: Copy this folder: UniServer3_2a/ UniServer3_2a /diskw/user/local/mysql To: UniServer3_3/ Uniform Server /diskw/user/local/mysql That completes the database installation. MySQL 4 database contains tables for the old phpMyAdmin package these need updating to the new version of phpMyAdmin. Just a matter of deleting the old and replace with the new. 5) Delete the old phpMyAdmin folder UniServer3_3/Uniform Server/diskw/user/local/mysql/data/phpMyAdmin 6) Copy new phpMyAdmin contained in mysql_old/data into mysql/data Copy folder: UniServer3_3/Uniform Server/diskw/user/local/mysql_old/data/phpMyAdminTo: UniServer3_3/Uniform Server/diskw/user/local/mysql/data 7) Delete folder mysql_old that's it run the server and check it out. You can run with this however if you look in the MySQL error log fileUniServer3_3/Uniform Server/diskw/user/local/mysql/data/{your name}.err You will find two warning messages similar to this: 060504 21:17:40 [Warning] mysql.user table is not updated to new password format; Disabling new password usage until mysql_fix_privilege_tables is run060504 21:17:40 [Warning] Can't open and lock time zone table: Table 'mysql.time_zone_leap_second' doesn't exist trying to live without them They are only warning messages and can be safely ignored unless your programmes use these extra facilities. To resolve the above follow these instructions 8) (see note 1) Obtain a file named: mysql_fix_privilege_tables.sql 9) Save this file in the following folder:UniServer3_3/Uniform Server/diskw/user/local/mysql/bin 10) (see note 2) Open NotePad (or any other text editor) copy and past these two lines into it mysql -u root -p mysql --force pause Save the file as fix_tables.bat it can be named what you like make sure you use .bat and not .txt.Save or move the file to the following folder:UniServer3_3/Uniform Server/diskw/user/local/mysql/bin 11) Start your server and start MySQL 12) Navigate to the batch file fix_tables.bat (using Windows Explorer) run it (double clicking on it name or icon). When requested for a password type in root The batch file will run and update your database. You can safely ignore the errors these are expected (some of the tables exist hence duplication errors are reported and that's whey you cannot use phpMyAdmin and need to use a command line) 13) All that remains is to shutdown and restart the servers. Check the error log and test your programs. Note 1: How to obtain the file mysql_fix_privilege_tables.sqla) You can download it from??? I tried in vain to find a site (sorry). Ask the UniServer development team for it (well they removed it to save space)c) I must confess the one I used came from a WAMP5 installation. d) Its only a text file see my reply!!!! Copy and save it using note pad. Note 2: Breakdown of command line mysql --- Database program -u --- user name -p --- password (none given forces you to enter one) mysql --- data base name --force --- continue even if we get sql errors pause - it allows you to see what happed (forces you to press any key) My personal reason for downgrading I had Zen Cart running on 3.2a with no problems. However, 3.3 refused to play ball because of MySQL 5 after performing the above mod it now works fine. I like 3.3 with the extra bells and whistles.
