Replication Error On RedHat AS 4 ( 5.0.33)


I download the newer MySQL version 5.0.33. And i compile it for multi-threads support on my 64 bit Redhat AS 4 running on DELL 2950. Everything is fine while installation time.

But error occues when another slave MySQL contact this new MySQL version master. After trying, I found out some kind of error "ONLY" happen on 64 bit RedHat AS4 and running with mult-threads MySQL.

I wound not wanna downgrade my 64 RH4 AS to 32. Although "Non-Multi-thread" MySQL can well run on my 64 bit RH4 AS, multi-threads MySQL still my prefer if it can work out.

Replication Error
I have set up master/slave replication between 2 servers (1 master,
1 slave). However, when I change a table on the master (e.g.
by inserting a row), the same table on the slave is not updated.
The strange thing is that if I enter SHOW SLAVE STATUS on the client,
it gives me the same offset in the binary log on the master as the
master gives when issuing SHOW MASTER STATUS (both entered after the update).

I'm trying to replicate the tables in the database 'dbmail'

If you need more info, please tell me!

my.cnf on master:
# You can copy this to one of:
# /etc/mysql/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /var/lib/mysql) or
# ~/.my.cnf to set user-specific options.
#
# One can use all long options that the program supports.
# Run the program with --help to get a list of available options

# This will be passed to all mysql clients
[client]
#password = my_password
port = 3306....................................................

Replication Error
I have a master and a slave. Replication was working fine initially but now when I do 'show slave status', I see this as the error
Error no 1449
Error "There is no 'root'@'hostname' registered" on query.
I haven't been able to find too much information about this.. What would cause this error message? Thanks for any help.

Repeating Replication Error
I'm replicating several databases. The most active one has one table
with close to five million rows, one has about half a million and the
rest are pretty small. The master is version 5 on an ubuntu-5.10 box
and the slave is version 5 on a FreeBSD-6.0 box. Once a day the biggest
table gets an infile of several thousand lines. It always works fine.

Things will be great for about a week and then I'll get an error on the
slave, like today's:

060201 11:02:50 [ERROR] Key in wrong position at page 8563712
060202 10:54:25 [ERROR] /usr/local/libexec/mysqld: Table './test/test'
is marked as crashed and last (automatic?) repair failed

The slave process stops, I'll repair the table, restart the slave
process and things will be fine for some number of days before it
happens again. What's going on? The slave tables are never touched (I
have learned that running OPTIMIZE TABLE... on the slave will cause
trouble, so I don't touch anything on it.) Is this bad memory, or a
config issue?

Replication, Slave Thread: Error Connecting To Master: Access Denied For User:
I have MySQL 3.23.41 on a RH-7.2 Linux used as local server. I'm trying to replicate the databases from server (192.168.0.1) to another linux PC (192.168.0.3).

Following the manual, i grant to the master a user with file privileges, and
edit both my.cnf files. The master starts fine but the slave mysql.log shows up an error:

Slave thread: error connecting to master: Access denied for user:
replica@localhost' (Using password: YES) (0), retry in 60 sec

RedHat 8 And MySQL
I recently ran across an interesting problem, and I'm curious as to whether any of you out there have had the same problem.

A friend of mine was trying to get his MySQL server running on RedHat, and was having a difficult time. He could not connect from his windows workstation. After a short look at his user table, I could see it was set up to only allow local connections (an obvious default security measure). This is where it gets wierd.

From a SSH session, I created a super user with full rights to all databases on all hosts (allowed login from any host). But my friend still couldn't connect from his workstation. I finally realized that the mysql daemon is appending '@localhost' on the supplied username no matter what the user supplies. Thus, a non-local connection fails.

Perhaps I'm missing something here...I am obviously not a MySQL expert. But I was able to get my MySQL running very quickly on my Mandrake 9 box. It seems RedHat has made some changes to its distribution of MySQL. I'm not sure what to do next.

MySQL Redhat
I have installed MySQL 3.53 on two RH7.3 and one RH9.0 boxes.
On one of the 7.3 and the 9.0 box, when I try to connect remotely, it
takes about 45 seconds to connect, whereas the other 7.3 box connects
almost immediately.
The fast box has standard install of 7.3 with tomcat added.
The 9.0 box is straight RH9.0 standard install.
I can't find anything in common between the slow boxes, but not on the
fast one.

Thread_stack On Redhat 8.0
I saw this section in mysql manual.

"If you are using Red Hat 8.0 or a new glibc 2.2.x library, you should start mysqld with
the option --thread-stack=192K. (Use -O thread_stack=192K before MySQL 4.) If you
don’t do this, mysqld will die in gethostbyaddr() because the new glibc library requires
a stack size greater than 128K for this call. This stack size is now the default on MySQL

4.0.10 and above."

I am using red hat 8.0. Mysql is started automatically when my machine is started. How should I set this variable. Can I add this to my.cnf file and restart mysql. If so how should(format) I add it to the my.cnf file.

RedHat 9.0 MySQL, PHP CREATE
I have a RedHat 9.0 web server setup for intranet use. When the webmaster tries to use his CREATE DATABASE and CREATE TABLE scripts it tells him that he doesn't have the permission to do it. I've given all the necessary permissions to do it, I think. Any suggestions?

MySQL On Redhat Linux
To make a long story short, let me say I had MySQL working on Windows 98
and everything was fine. Well, I took the big leap and removed all
traces of Windows and Microsoft from the computer. (hooray!) Once I had
Linux running OK, I downloaded and installed MySQL using an RPM package.
I guess the server is running (it says it is every time the computer
starts and it stops successfully every time the computer shuts down)
however, I cannot figure out how to get the MySQL prompt.

I've searched the entire hard drive for MySQL, mysql, MySQL*, mysql* and
probably some others, too. The only thing I found was a shell script
called mysql that starts or stops the server if I am logged in to Linux
as root. I cannot figure out how to start the interactive program that
allows me to make select statements, inserts, updates, etc.
I'm wondering about some things:

Did I download and install the wrong thing?
Am I just not looking for the correct thing?

Did I install it incorrectly?

MySQL As Part Of RedHat 9 Install
When I did my RedHat9 install, I choose Workstation and customized the
packages I wanted install. As a part of that customization, I chose
mySQL DB; however, I can't seem to find any RedHat documentation that
says how to get to these installed packages. I would like to just start
using them, but not sure where to start. Any hints to get up and going
quickly?

Problem Installing MySQL Max Rpm On RedHat 9
SELECT *
FROM Distance, LorryDetails
WHERE cavan = (Select min (cavan) From Distance where cavan>0);

here is the results i am getting

source ,Cavan, Athlone, Cork, Galway ,LorryID, LorryReg, Position
Athlone 90 0 180 80 3 02-CN-8001 Cork
Athlone 90 0 180 80 7 00-CN-1000 Cavan
Athlone 90 0 180 80 10 02-G-8001 Galway
What i want to try and do is compare the Values with the Column names and get the shortest path. for example when you compare the position cort with the column cork it is 180, cavan is 90, and galway is 80. Galway is the nearest to athlone so i want to narrow down the results to just give me back the row where the position is equal to Galway.

Activating MySQL In RedHat Linux 9
After being absent for a while now I'm back with this question: Does anyone know of any guide on how to start mysql on Linux? Actually I was writing a long complain that mysql doesn't run on linux! But during the writing I could sort of fix it! Now it works, but only the mysql & test databases are not active coz their directory isn't created. I think I can do something for it myself! I just wanted to know if any of you went through the same experience: running mysql that is already installed with your Linux package, not grabbing a new mysql and deleting the old one and installing the new one!

Installation Problems On RedHat EL4 On Ia64
I'm running RedHat EL4 on an ia64 system. I've been using
PostgreSQL for a while but I now have an app that I think
requires MySQL so I wanted to try it out.

I tried installing MySQL-server-standard-5.0.18-0.rhel4.ia64.rpm
and I get an error that it conflicts with mysql-4.1.7-5.RHEL4.1,
so apparently I've already got MySQL 4.1.7 on the system.

I want use PHP with MySQL, which means I have to configure PHP and
tell it where the MySQL headers are. But I don't seem to have
headers, at least not that I can find.

I tried uninstalling MySQL 4.1.7 first but it says that dovecot and
perl depend on it. I tried installing the "headers" rpm for 4.1
but the only one I found was 4.1.18 and rpm says it conflicts with
mysql-4.1.7-5.RHEL4.1.

So, any suggestions? I don't think I'm currently using MySQL for
anything, but I don't want to break perl. I'd like to get 5.0
running. I just don't know enough about Linux and RPMs to be
confident that I can uninstall 4.1 and install 5.0 without screwing
something up.

Java In Linux (Redhat 9) To Access MySQL
Using a Java program, I can connect to the test database in MySQL. The
test database is installed using a MySQL utility, and it can be accessed
by any user without supplying a password. The relevant lines in my Java
(Java version 1.4.1) code are:

Connection con = null;
String url = "jdbc:mysql:///test"; // <== no user or password specified
con = DriverManager.getConnection(url);

However, when I try to connect to the accounting database (built as one
follows the Larry Ullman's "MySQL" book), the program fails. I need to
supply a user and a password. The relevant lines are now:

Connection con = null;
String url = "jdbc:mysql:///accounting?user=root&password=pswd"; // <==
con = DriverManager.getConnection(url);

I cannot get a connection. The error message is:

"Invalid authorization specification: Access denied for user:
'root@thorvald' (Using password: YES)"

(thorvald is my machine name.)

I have tried all sorts of variations on the url, trying to access the
accounting database, with no success. I can use the same user/password
of root/pswd within the mysql monitor to access anything I want.

Any ideas?

Again, I am using Linux (Redhat 9) , Java 1.4.1, MySQL 4.0.13, and the
MySQL ConnectorJ 3.0.8 (for Java access to MySQL).

Replication
I have 3 databases replicating (ver 3.23) A to B and B to C

Replication
I have a *big* problem and before solving this problem I cannot go productive with my application. Pleas help me to find a workaround.

I have two host (A and B).
I have setup a replication (from A to B).
binlog-do-db=db1 (only db1 will be replicated from A to B).

Consider the following example:

1) On host A:
mysql
use test;
create database db2; (db2 is created only on host A)
quit

2) On host A:
mysql
drop database db2; (this command is replicated on host B)

After step 2 the replication stop.
On host B the command "show slave status" report the following error:

Last_error: Error 'Can't drop database 'db2'. Database doesn't exist' on query 'drop database db2'. Default database: ''

The problem is that if I log into host A, the commands executed before the command "use" are replicated to host B.

I have a set of applications that are used at my coporate workplace, they are used locally by the corporate network users -

I have MySQL 3.23.41 on a RH-7.2 Linux used as local server. I'm trying to replicate the databases from server (192.168.0.1) to another linux PC (192.168.0.3).

Following the manual, i grant to the master a user with file privileges, and edit both my.cnf files. The master starts fine but the slave mysql.log shows up an error:

Replication
I have 2 MySQL servers (windows environmment). I want to setup one way replication between them; Server B must contain the same data as Server A, but if change data on Server B, this change may not be propagated to server A. Is this possible and how do I proceed?

Replication - 4.0.16
We replicate several databases in a master server to three read-only
servers, for load balancing. Sometimes the users notice that one of the
three databases have not updated a few transactions. Has anyone written a
tool that can compare two databases for content? I would sleep much, if I
could run a weekly process that compared each of the replicated databases
with the master.

Replication
I'm replicating just a few tables from the master to the slave.

Sometimes the slave stops with the following error :
"Error 'Table 'xxx' doesn't exist' on query.

That table only exists on the master, and I don't want it on the slave.

Replication
I was running replication successfully for months. I had to increase the max_allowed_packet variable on the master db for other needs. When I did this I noticed that replication stopped working on my slaves. The error on the slaves said the the bin log on the master or the relay log was corrupt.

Replication
I set up a replication with MySQL 4.0.13, it works very fine, but
unfortunately only for several hours (between 10 and 30 hours) Has
someone an idea why the replication stopps?

Replication
I want to ask whether I can do replication in the following case.

innodb (master) --replication --> myisam (slave).

Replication

I have 2 servers, A and B. A is the primary server and master in mysql.

B is the redundant server and the slave in mysql. A is replicating to
B. Now A fails and B becomes the primary server (still slave in
mysql?). A finally comes back up, but instead of switch primary status
from B back to A, A becomes the redundant server and B stays as
primary. Now, I need B to be master in mysql and A to be slave in
mysql.


I don't know if this can be done the way it needs to. If it can I
really don't need a step by step process unless someone is really
willing to give that to me. I just would like to know if this can be or
has been done.

Replication
I have connect my web server (master) to my local server (slave) through
dial-up and replicate 2 databases.

a) Is there a log file describing the replications that happend (if any)?
b) how do I know when to stop the dial-up so not to stop any data transfer
through repliication?

Replication
Can I get the master (or slaves) to automatically remove the binary
logs once they are processed by all slaves?

It says in the mysql manual :
If you are using replication, you should not delete old binary log
files until you are sure that no slave still needs to use them. For
example, if your slaves never run more than three days behind, once a
day you can execute mysqladmin flush-logs on the master and then
remove any logs that are more than three days old. You can remove the
files manually, but it is preferable to use PURGE MASTER LOGS, which
also safely updates the binary log index file for you (and which can
take a date argument as of MySQL 4.1). See Section 13.6.1.1, "PURGE
MASTER LOGS Syntax".
http://dev.mysql.com/doc/refman/4.1/en/binary-log.html

This seems to suggest that you need to estimate an amount of time it
will take for all slaves to be up to date, or have processed all the
binary log files. If this is the case, how do you take into account
something going wrong with the slave/s by not deleting the binary logs
if this happens?

It seems like a better idea to just remove the binary logs when the
master has full evidence that all the slaves have correctly processed
them (I/O thread retrieved them)... is there a way to do this?

Replication
I have 3 databases replicating (ver 3.23) A to B and B to C

On C I want to modify one of the tables and add a column. Tables A and

Am Working on a distributed database system.My idea is using replication by having several slaves running on one machine and they all connected to different masters each on different machines at the branches.

First question is this best approach?
Second question is can different slaves with different parameters run on the same machine and if possible what key things must i look for?
