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?

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!

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 With Multiple Servers In Mysql ?
I want to establish replication between multiple (currently three) servers. Updates/inserts/deletes may happen on all of them. The idea I came up with was to do a "circle"-replication. The problem with this is, that if one server fails the rest may not get updates (until the server is back, obviously). Does anybody have an idea how to establish such a replication in a fail-save manner ? Code:

Installing Multiple MySQL Servers
If you need multiple MySQL servers running, what's the difference between installing MySQL once and running multiple servers (by issuing multiple mysqld commands with their own options), versus actually installing two or more DIFFERENT instances of the same version of MySQL? What is typically done? What are the advantages/disadvantages of either method?

Using Linux Symlinks W/Multiple MySQL Instances
We run multiple instances of MySQL on Linux. Each instance has its own directory structure. Along with other databases, each customer has a 5GB non-updating database that is used only for reference. Currently we have multiple copies of this database, which takes up a lot of disk storage. Since this particular database does not get updated, is it okay to have a single copy of it in a commonly accessible location and give the separate instances of MySQL access to it through symbolic links?

Moving Multiple Databases From Different Servers To One Db Server
I'm trying to move three MySQL databases, currently residing on two different servers, on a third dedicated database server: Old Server 1: db1a, db1b Old Server 2: db2a New Server 3: <move db1a, db1b, db3a here> All three databases are quite large, 8+ gigs in size, so I was suggested to copy over the data directories, containing these databases, to /var/lib/mysql on the New Server 3. I can foresee potential conflicts due to files and directories with same names on both Old Server 1 and Old Server 2 (specifically, ib_logfile0, ib_logfile1, /mysql/*, etc.). Are there any MySQL tools available that would allow me to either fix the databases afterwards, or consolidate the overlapping data? Maybe a better way to achieve this?

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.

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.

2 Mysql Servers
I have a Mysql server lets call it "Production", but also do lots of development when traveling (offline) on my laptop, where i also have mysql instance installed + php + apache .... both MySql are 5 and same build running on windows. What would be the best way to "replicate" Mysql from my laptop to the server when I get connected. One way solution (from Laptop to Server) would be great, but both ways (whichever is newer gets replicated would be excellent). thought about replication but i undertood that the master 'version' will always be writen to slave. We need to consider any kind of changes, table changes, dbs change, users, data, etc... Hope you can give me a light, it is not a large amount of data, and i would not mind a very manual process, as long i can script it or if it is a few steps only.

MySQL Databases And 2 Servers
We are planning to reprogramm our search machine and website. Since we have call agents who query the same database as the customers do, we had the idea of splitting the database to 2 servers. The call agents can update customer data with our intern webinterface, which not only concerns tables that are for the call agents, but also concerns tables of the search machine, holding company data such as address, search words, etc. Since the customer himself can administer his own data, as well as the call agent (or media agent), I was thinking of doing following: * I have 2 servers. Server 1 is responsible for the search machine and just serves customers searching for a company or for products. The MySQL database is there just for querying. * Server 2 serves call agents, as well customers who want to change their data, reading and writing. * Since the search machine should of course show updated data the call agent or the customer have eventually changed, the data from server 2 must be synchronized with the MySQL databese of server 1. (e.g. at midnight) Questions: ------------- 0. Is the above described the right way? 1. What do I have to consider when planning the database structure? 2. How do I synchronize? Can I copy specific tables from one server to another using cronjobs (crontables)? Since this is absolute newland to me, how? Any expert knowledge or experience with MySQL replication or MySQL clusters? I think replication is just thought for mirroring, or am I mistaken?

Consolidating MySQL Servers
My organization currently has 2 different MySQL database servers. We are in the process of moving the databases from Server A to Server B and have Server B be our primary database server. I've done some research on the web and believe the best option is to use the "mysqldump" command to remotely recreate Server A's databases on to Server B. Can anyone please advise whether this is the best option? Also, using the "mysqldump" command, are there any overwrite issues, such as existing tables on Server B being overwritten by tables with the same names from Server A. Would these tables be simply overwritten or would there be any type of warning prompt?

Two MySql Servers, One Database
I have two MySql servers, one in my local PC and one as a testing server in the next room. Using DW 2004 I can use the "put" and "get" to get my PHP files from one PC to the next quicky. How can i do that with the two MySql servers? So if I change the Structure of a table or and data to the Mysql database on my local PC, it will send the changes to the testing server.

Detecting MySQL Servers On LAN's
I want to build a script/app to make an inventory of all computers that run MySQL servers. And if possible return their versions. I would be running this script/app from a Windows system, so I would like to use VBScript or Visual Basic 6.0. This way the people I am working with will be able to understand what I am programming too. Further more it would be nice if I couldn't only detect the Windows machines, but also other systems (mainly Linux). Can this be done? And how?

Apache & MySQL In Differentes Servers.
I've been running a slow Debian machine, with Apache + PHP + MySQL. But, with the time and usage, it's getting to slow to use MySQL. So, now I have another machine (running Debian too), and i've installed MySQL there with all the databases and users moved on to, it works perfectly (with phpmyadmin). What I want is to have the first machine running apache + php, and in the other MySQL. How can i do that ? I've tested making a mysql_connect from a page hosted in the first machine to the other one running MySQL but i didn't work, couldn't connect. I've tried redirecting mysql port to the other machine (iptables) and that didn't work either... Resuming... I want all my users to work with the first machine, they have their accounts in there and all their files, their pages, etc... And the database running in the other machine.

Migrating Mysql Servers Between Windows Machines
I just had to do a mass data switch to my windows server.It's been running apache with php and mysql for over a year now. This data switch meant i just copied the files over to an almost exact copy of my current windows installation.Unfortunatly mysql didn't startup the way everything else did.Now the server won't start at all(dies on startup.) If anybody knows any problems that would probably result from migrating MySQL i'd be highly appreciative. Short of that,how can i find the errors mysql is having,thus allowing me to diagnose a solution the problem.

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.
