RE: Fatal error: Please read Security section of the manual to find out how to run mysqld as root!
i see. there is an option in my.cnf which says which user to run mysqld as. change this to mysql. make sure that mysql is a real user on your system. also, be sure to set the full path to the basedir and datadir in the my.cnf user = mysql basedir = /usr/local/mysql datadir = /usr/local/mysql/data or whatever your paths are. -Original Message- From: Kenneth Illingsworth [mailto:[EMAIL PROTECTED]] Sent: Friday, November 22, 2002 4:06 PM To: [EMAIL PROTECTED] Subject: RE: Fatal error: Please read Security section of the manual to find out how to run mysqld as root!

i am using the older v1.19 DBI. i looked at that line and it should not
cause a problem. the values are stored, even after the handle is destroyed
or the connection closed. the error is complaining that i should destroy
statement handles or call finish. thanks for the respones.

Try moving your $dbh-disconnect call after it prints out the
fetchrow_array()
my ($t_user,$t_password,$t_prefs) = $sql_check-fetchrow_array();
if($debug_state) {
print S: $t_user,$t_password,$t_prefs\n;

$dbh-disconnect();
If your using an older version of DBI, like 1.13 or .14 you may need to call
the
finish() after you execute() your statement handle.

So far, I have been able to deal well with the hardware agents (network, disk, nfs, cpu). However, when it comes to creating software agents for MySQL, I am struggling. If anyone (even those who haven't attempted this) has any ideas for software agents, please respond.

MySQL Log Management
I am looking for some suggestions for MySQL log management. Just some people to respond to this message with their log rotation, and archival methods. I am just curious to see what others are doing, and to possibly suggest a method for myself to use.

MySQL determination of hostname?
How does MySQL determine hostnames when checking access permissions? I assume it uses whatever methods are available to the system (/etc/hosts, NIS, DNS, etc...). Will it use those services in the order they are listed in nsswitch.conf (Solaris)? What about for determining its local hostname? Does it use the hostname function?

MySQL General Questions
I have read the documentation thoroughly, however there are still some things unclear to me, and others that I want opinions on. I am dismayed at what I see as a fundamental lack of server administration documentation. Much of the docs focus on the SQL aspects of MySQL. There is only a minor portion dealing with server administration. Most of which deals with installation, starting/stopping MySQL, and minor database administration. I would like to see more from a true System Administrators point of view. I am still unclear as to how MySQL utilizes memory. I believe that for each client thread, there is a portion of memory only for that client, and then there is some memory that is shared between all clients. Is this correct? How can I tell how much memory is being used by a single client? What is the difference, if any, in MySQL parlance between a thread, and a connection? I want to be able to look at my server and see if the physical system is giving good performance, or if I need to provide more resources. I don't really know how to do this for MySQL though. I have written some applications to use data from various MySQL databases on my server. However, I am trying to find the best way to write these applications. If a client has a (thread/connection) to the MySQL server, can that thread support multiple simultaneous queries? Obviously this question is loaded, but lets say I am using Sendmail tied to MySQL. Would it be better to write a sendmail that for each daemon running, has a persistent connection to the MySQL database, and uses that connection to query for each piece of mail it delivers. Or would it be better for my Sendmail to open a new connection for each piece of mail? I have seen the max_connections variable, and have adjusted this at least once. However, what does MySQL consider a connection? Backups, backups, backups? What is the best way to do a backup? What about table maintennance? If I use myisamchk or another command line tool, do those lock the tables? If so, what kind of lock? If I run a CHECK table from using the interactive mysql, do I need to lock the tables first? I know these are a lot of questions, if you have an answer to all or any part, email me directly please. Also, if you would like to include additional information please do so. I am not really a DBA, and am looking for more information from an SA point of view.

Re: Mysql and tmp dir problem
Have you checked that /tmp isn't full? If /tmp is its own filesystem, and its full, then no matter what the permissions you won't be able to write to it. At 10:24 PM 10/2/01 +0200, you wrote: When execcuting some queries in MySQL (3.23.42) on Redhat 7.1 i'v got error: ERROR 1: Can't create/write to file '/tmp/root-tmp.03a811f23b28d045/files/#sql61ba_d_0.MYI' (Errcode: 2) /tmp dir permission is 777 so there shouldn't be problem. When i create dir which mysql wants to write to everything is ok. MySQL server, works as mysql user. What's wrong? By the way, should mysql create tmpdir as root-tmp, not mysql-tmp ? - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Change options during MySQL compile???
I understand that mysqld will normally look in /etc for the my.cnf file when it starts. I would like to change this behavior so that it will look in /usr/local/etc. I know that I can do this with a command line option, but I want this to be the default behavior. I thought the the configure option --sysconfdir would do this. It did not. Does anyone know how to do this? Also, I know how to compile mysqld with extra character sets, is there anyway to limit the character sets that are built? I don't want support for all of the character sets, just a few.

Re: Remote MySQL Console?
Setup a user account that can access your databases from the remote hosts you wish to use. Do this using GRANT. Then install the mysql client on those systems and use mysql -h hostname -u user -p password to connect.

MySQL vs. Oracle
I am currently trying to examine the benefits of continuing to use MySQL over Oracle. I need to know what MySQL's features are vs. those of Oracle. Also I am looking for performance data. What kind of scalability does MySQL have vs. that of Oracle. Is there (or will there be) any support in MySQL for something akin to Oracle's Parallel Server? Can I use MySQL with Veritas?

HA Setup for MySQL
I recently started experimenting with a way to setup MySQL to be load-balanced. I installed 2 servers with MySQL, NFS mounted the /mysql/var directory, then moved the grant tables to /mysql/grant, and created a symbolic link from /mysql/var/mysql to /mysql/grant. This appeared to work correctly, however, my tables soon began to show corruptions, and sometimes when an insert was made, and then immediately following a select statement was made against that data, it would not be found. I figured this was due to memory cache not being flushed to disk before the select statement. So the other server would have no record of the data. I adjusted the server settings so that data was always written to disk. This solved that problem 99.99% of the time. However, I was wondering if perhaps the server doesn't always try and select from the table on disk, but rather the table in memory. So that if server 1 inserts data into the table and writes it to disk, then server 2 selects data but only from the table it has loaded into memory it won't be able to select the new data? Has anyone ever tried something like this? Also, I want to try setting up replication such as A - B - A. I want to be able to put both system behind a load-balancing switch. If an insert is done on server A, then server B is updated, then server B sends an update to server A, will server A know to ignore it since it originated from server A?

Re: HA Setup for MySQL
I'm not sure if that was a problem or not. I am actually very interested in the second part of my query regarding replication. An earlier post mentioned that if I am using A - B - A replication behind a load-balancer, that I may lose performance. I am only slightly concerned with update performance, and am more concerned with select performance. I believe that if the tables between the 2 systems can be kept syncronized reliably, that I will can a performance increse for selects by using the load-balancer. This is good because the majority of my apps do selects. I want to know if an update to server A updates server B will server A ignore the update when it comes in from server B?
