SOTL wrote: Well I change the datadir in mysql-max and I have generated numerous versions of my.cnf directing MySQL to my desired directory each change causing MySQL refused to run. So I keep playing around with mysql-max and found that there is a second place where the config file does a test of the datadir so I changed that. At that point MySQL would open and did switch data directories. Continued to play with MySQL, making and deleting DB et. i.e. all the things a newbie does with a book and a new program. Then, I shut the box down for the night and went home. It is after all only a test box at this time but it is damn noise so to keep the piece down it goes. Anyway, firing it up the next afternoon I was amassed to discover that MySQL would not open with the same old error message that it could not find the data directory. I the reset the data directory to the original settings and MySQL again started working. So, there are at least 3 places that you MUST change the data directory at in configuration files in order to change the data directory. Best best is to do it by symbolic link as no newbie is going to figure out how to do it in configuration files. My only comment: How quaint, how 1950s that there exist programs in which one can not select the data directory. Frank PS. Thanks for the help. It is definitely appreciated. Frank, One thing to keep in mind, when changing things in the file in /etc/rc.d/init.d - You have to stop and restart MySQL before they take effect. The values in the script are only read at startup. You should probably learn about the service command. If you are using mysql, then you would run service mysql start to start it, service mysql stop to stop it, and service mysql restart to test your changes. If you use mysql-max, then use that in mlace of mysql in the service command. You may also be having a problem because on not understanding how the script works. Not every instruction in the script get run. It does tests, and if a value is set, then it skips part of the code. This is why you see references to /etc/my.cnf in the script, even though creating or changing this file has no affect on MySQL. This is because that part of the script does not get accessed on a Mandrake box. So you will want to be carefull aboout changing things in the script. The values that you would want to change are always at the beginning of the line, and normaly have a comment block before them.

I simply do not understand and am very happy for your help which I thank you very much for. I have checked I do not have a file called S90MySQL in any location. I especially checked that it does NOT exist at /etc/rc5.d/S90mysql. Nor do I have a file /etc/rc.d/init.d/mysql. What I do have is a file /etc/rc.d/init.d/mysql-max. I had taken a look at this file earlier but dismissed it assuming that it is not the correct file. MySQL-Max was placed on both boxes at one point in time and the removed. On reinstallation of MySQL standard MySQL was installed not MySQL-Max. This may be the source of the configuration file issue. Currently both boxes have MySQL installed. I have printed the MySQL-Max file and it is a 4 1/2 pages #10 font program which I can read some of - not much since I am not a programmer. One interesting thing I did notice is that it refers to checking a configuration file called my.cnf which I do not have. As I know that I do not have the technical expertize to create a my.cnf file I would appreciate someone sending me a copy of a simple one that functions. Thanks Frank The mysql or mysql-max files are the scripts used to start mysql. There are a few config options in the file. The important one for your is the line: datadir=/var/lib/mysql If you want your mysql data someplace other then /var/lib/mysql, then you will need to chege this line. You will want to create a my.cnf file in this directory. It can be an empty file. The script fills in the missing entries with usable defaults.

Thank Frank You may want to take a look at /etc/rc.d/init.d/mysql to see were a lot of things are by default, and how they are set. If you leave pid_file= blank, it gets set in this file. The file gets created when mysql starts, and contains the Program ID (PID) of the MySQL server. Looking at this file, it looks like this is where you would set your data directory, and you would put my.cfg in the data directory you set in this file.

The files in /etc/rc.d/rc#.d are symlinks to the files in /etc/rc.d/init.d and are created/removed by chkconfig. The /etc/rc#.d entries are symlinks to the directories in /etc/rc.d.

So, I open another .cnf file and edited to be identical by changing name-X within the [name-X] to [MYSQL] and then editing a linewith datadir= /dir/dir/file-name to datadir=/mnt/System_Data The final product was: file = /etc/my.cnf with contents of [MYSQL] datadir=/mnt/System_Data Then I tested it and it worked. I would not bother people on this list with this but it is not the first time it has happened. That is I type a configuration file check it re check it and it refuse to function then copy and edit a file from some other location edit it to where it is exact and I do mean exact equal the the one I created from the keyboard and it function correctly.
