Re: Access denied for user 'debian-sys-maint'@'localhost'
Hi Jesse, If you're specifying the password in plain text, you shouldn't put the PASSWORD directive in there; you only use PASSWORD if you're using the hashed password that MySQL will actually store. GRANT ALL PRIVILEGES ON *.* TO 'debian-sys-maint'@'localhost' IDENTIFIED BY 'LongPasswordHere' WITH GRANT OPTION or GRANT ALL PRIVILEGES ON *.* TO 'debian-sys-maint'@'localhost' IDENTIFIED BY PASSWORD 'HexadecimalString' WITH GRANT OPTION Also, you will need to execute FLUSH PRIVILEGES once you're done, since MySQL normally only checks the privilege tables on start-up.

Okay, now that sounds a lot better. Waiting for 5.1 GA then. Although it only provides the very basics. I still have to postprocess/aggregate the log to find who did what and how long that all took. Or - looking at your original question it may be able to narrow down the source of the queries if you can graph your data more often - maybe every 10-15 seconds instead of a longer interval to help you profile which applications are hammering your db server. This is a webhosting services machine. I don't know who of the users is doing what and what applications they have installed. Recently I found one of my applications being vulnerable to senseless recursive bot requests that took quite a bit of the time. That was by chance because I had also looked into the web server requests diagramm, which I can separate by users. And in that case, my colour was clearly visible... ;) So maybe it will already help a lot to see for which user account the database server is working most in a certain time range. -- Yves Goergen LonelyPixel [EMAIL PROTECTED] Visit my web laboratory at http://beta.unclassified.de -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
failure to connect to mysql-server at localhost
Hi all, i am installing a library automation software called koha which uses mysql-server. i initially installed version5.0 and later uninstalled it because the system was giving me some errors. i installed the lower version(mysql-server-4.1). when reinstalling koha i get the following: MYSQL ROOT USER PASSWORD To create the koha database, please enter your mysql server's root user password: Password: CREATING DATABASE Creating the MySQL database for Koha... ERROR CREATING DATABASE /usr/bin/mysqladmin: connect to server at 'localhost' failed Couldn't connect to the MySQL server for the reason given above. This is a serious problem, the database will not get installed. Press ENTER to continue: i continued with with installation to the end. As a result of the above problem everything seems to work (adding members, searching and importing records from the internet using z39.50) But it doesnt add bibliographic records to the database- whenever i try to add records i get a server error. will be grateful if somebody can sort me out. i am using ubutu 6.06 operating system.

This is causing some of the sql's on the slave to be slower than master for the same select statement on both master and slave. RES is the amount of RAM used by the process, as controlled by the memory allocation (Linux kernel). It depends not only on the address space requested by the process, but also on those by other processes and on the paging / swapping policy (which AFAIK depends on the which process accesses memory how frequent). The MySQL process on the slave has a smaller RES if and only if there is reason for the Linux kernel to allocate less RAM, this typically means there are other processes requiring it more urgently. *If* the database load on the master is higher, or accesses more data, or there is less competition about the RAM, it is only natural that RES for the slave is less. Database performance strongly depends on caching: If the cache on the master already contains the needed pages, and on the slave it doesn't, it is normal that the first statement needing them has to wait for disk I/O and so is slower.

PHP, MySQL questions
Hi there I am going to make 2 Webserver at my work going to handle 50 mil hits per month... They are using Linux already. But being a FreeBSD fan, I have proposed MySQL and FreeBSD to my Boss convincing him that MySQL and FreeBSD is more Fast and Secure solution for his needs... And now I want to show the results... *Hardware: *Dell PowerEdge 2950 III having 2 x CPU 3,0 GHz Intel Xeon L5450 Quad-Core 2x6MB cache WITH 16 GB RAM. *Tools:* 1. FreeBSD 7 Production Release 2. Apache 2.2.9 3. MySQL 5.1.26 4. PHP 5.2.6 My question is, *To get the speed, performance and security*: Should I use Ports or Packages to install all these tools One by One? *OR * Should I use TAR files and compile them manually. For example giving command line arguments and commands like ./configure --prefix=/www --enable-module=so make make install cd ../php-xxx ./configure --with-mysql --with-apxs=/www/bin/apxs make make install etc I have googled but still haven't reached to solution...personally I would prefer comiling them with command line arguments but then I seek some help from you guys i.e. How should I write this ./configure..stuff in FreeBSD and what would be the best options combination, I must choose to get the speed, performane and security in Apache, MySQL and PHP?

Master-to-Master replication on same server
I recently installed 2 instances of mysql on the same server, using port 3307 for the second server, the normal 3306 for the first server. I found that while logged onto that box I could communicate to the 3307 instances using the socket parameter. Using the port parameter (--port=3307) didn't work. I am now trying to set up master-to-master replication on that machine, where the 2 masters are the 2 instances running on that machine (sounds a little flaky, but it's for a dev box and it ought to work). It's not working and I'm wondering if it's because I can't specify the socket the 3306 master needs to connect to on the 3307 master. In the change master to command I can only specify the port. I did specify it as 3307 but the slave still can't connect. Has anyone done this? -- Jim Lyons Web developer / Database administrator http://www.weblyons.com

Suppose if i add one more machine with 1.8TB again, what will be the effective space available for Data Storage ? Any formula from where we can find out How much will be the effective space for storing actual data when all 3 machines are in cluster? Please advice me on this .
