Nixed my mysql user, heh heh [SOLVED]

As noted in a previous post, I inadvertently deleted several system files, and I thereby lost my mysql user, so now the daemon can't start.
I made a user "mysql" but it didn't help.
Should I run mysql_secure_installation and first backup my config files? I did change those files a bit.
Thank you.

Mysql user - ? password

Hi all,
New to OS X but not Linux. I see that a user 'mysql' exists on my machine. I do not see any way to assign it a password so I can use it as the root account for mysql. (I had to install as machine root to be able to log in with 'mysql -u root -p' and then respond with the password.
It seems that the /usr/local/mysql directory should belong to mysql user instead of root.
Anyway, I do not see any way to use netinfo to set mysql's password.
Also, one big gap in the documentation on the Apple and MySQL web sites is that there is NO DISTINCTION between the machine's root user and MySQL's root user. Maybe there is none but that doesn't seem right to this neophyte.
Open to all constructive criticism. It you can point be to the right refs I am more than willing to read up on this topic.
Thanks,
Bob

The mysql user on OS X doesn't have a password: it's not a login user or has no shell. I'm not sure of the technical details, but basically, you don't deal with OS X's mysql user like a regular user.
It seems that the /usr/local/mysql directory should
belong to mysql user instead of root.
I think the only directory that has to belong to mysql is the data directory one level down from there:

You use either mysqladmin or the mysql command line program (or some other program).
Also, one big gap in the documentation on the Apple
and MySQL web sites is that there is NO DISTINCTION
between the machine's root user and MySQL's root
user. Maybe there is none but that doesn't seem
right to this neophyte.
You're sort of right: that's not right. OS X has its users and MySQL has a completely different set of users. The MySQL root user has nothing to do with the OS X root user. And you can have dozens of users in MySQL without corresponding users in the OS. And none of them have to share passwords. Look at this page for more on granting users permissions in MySQL databases.
I'm sure you'll have questions, so post back if some of that doesn't make sense...

MySQL User account

I'm trying to create a user account for MySQL. When I type in the Short Name "mysql" I get an error message "Name is used by another user". I don't know who or where this is being used. I'm trying to create a virtual directory to install and test an eCommerce site on my local hardrive.

mountain gal
Welcome to Apple Discussions!!
When I type in the Short Name "mysql" I get an error message "Name is used by another user".That is correct. OS X by default installs a mysql user, with UID 74, and "real name" "MySQL Server".
Note, you cannot log in as this user (no Home directory, no "shell").
Not having set up MySQL myself, there's not much more I can add. But if you post your question again in the UNIX forum, I'm sure you'll get good advice there.

Need some help from the smart apple users hehe

Ok so i had to reformat my pc due to having a nasty virus.
So the thing is that i have some music/photos on my ipod touch 3rd gen 32 gig that i dont want to lose.
When i login to itunes the only option i see is to import the library to my ipod but that would delete all the files i do not wish to lose.
How do i export all the contents of my ipod to the library?
Thanks in advance for all the help.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

read_buffer_size=262144

It is possible that mysqld could use up to

Hope that's ok; if not, decrease some variables in the equation.

To start mysqld at boot time you have to copy

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h lovelock password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/scripts/mysqlbug script!

Mediawiki, mysql, php? problems [SOLVED]

On Sunday my Arch install that is hosted by Slicehost became unresponsive to them so they had to do an emergency reboot. After it came back up my install of mediawiki was (and still is) only returning a blank page (at least in Firefox). After some digging I found out that part of the problem was that mysqld wasn't starting so I managed to get that fixed by commenting out the lines relating to innodb and putting in skip-innodb into my.cnf. But I'm still getting a blank page.
According to Mediawiki's manual, "A blank white page indicates a PHP error which isn't being printed to the screen." They give two lines to put into LocalSettings.php to force error messages but after doing that I'm still getting a blank page. Changing display_errors in php.ini to ON didn't have any effect. When I load the wiki in Safari I get the following error: "Got java.io.EOFException (Server closed connection while sending the HTTP header.): http://some_url.com/mediawiki/index.php/Main_Page". I have no idea what this error means and googling java.io.EOFException doesn't bring up anything very helpful. My PHP Test Page indicates that PHP is up and running.
Any ideas on fixes or where I can find more clues?
[EDIT]
Mysql was definitely the root of the problems with Mediawiki. I tried nearly every suggestion listed in the forums for fixing a mysql install that wouldn't start but nothing worked. I even completely uninstalled mysql and reinstalled it but it still refused to start. I switched over to postgresql and switched mediawiki to run with that. Problem solved.

There are some other things that must be done to connect to
the database
(such as passing the usernamee, password, and host info to
mysql_connect()
and storing the connection resource), and those might be in
the include
files. I generally place all of the connection parameters in
a separate file
that is located in a folder that can't be accessed by a
browser, for
security purposes.

I m now have no idea on how to create a registration link, ie update the database. please help..the examples i search through google were build by Jboss, strut, ApacheGeronimo which i m not familiar with.
Is it any "package" or "wizard" available in creating the login and registration page? Most of the webpage has build with user login and registration part, may i know how they "create" them?
Please help.. Thanks in advance!

hi,
You can use tomcat5.5 for this. you can get help from the following link.
http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html
If ur registrantion page is RegistrationPage.jsp then u can write it:
<a href="RegistrationPage.jsp">Registration Page </a">For Registration page u have to use session & for u can search this in javaworld.com site. MAy from this u will get ur solution

JDeveloper install is machine-based, not user-based ! [Solved]

Hi,
I am in a Windows 2003 domain development setup where several users can share the same computer to develop. From my understanding, JDeveloper install and settings handling is machine-based, not user-based ! This is quite a problem because if a user changes of computer to develop, he will lose his JDev settings. How can I solve this, by saving the user settings to a remote folder ?
Thanks
EDIT: I solved this problem by adding a JDEV_USER_HOME environment variable pointing to a shared folder.

Good Oracle DB book for MySQL users?

I'm new to Oracle. I have a good amount of experience with MySQL. I was wondering if there is a book written as an introduction to Oracle for people already familiar with MySQL.

Hi,
The best place to start is at the Oracle documentation site -
http://www.oracle.com/technology/documentation/index.html
and from there choose the 'DBAs' tab under 'Getting Started' and this has pointers to basic information.
Regards,
Mike

MySQL - how can I change an IP address restriction for a user [solved]

I'm getting "Host ... is not allowed to connect to this MySQL server" when attempting to connect to mysql. I read this guide which gives a solution but I have no idea how to physically implement the solution.
You can fix this by setting up an account for the combination of client host name and user name that you are using when trying to connect.
I want to change the access from "localhost" to any address on my LAN (192.168.0.*) for user facade, but am unsure of the proper syntax.

Host can be a combination of IP/netmask. In your case, something like:
UPDATE mysql.user SET host = '192.168.0.0/255.255.255.0' WHERE user = 'facade'

OK super random, it works now.
First off I too took and added skip-grant-tables to [mysqld] /etc/mysql/my.cnf
restarted mysqld and finally had passwordless login. From within mysql i ran
UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
FLUSH PRIVILEGES;

Php/mysql: can't write to mysql database [SOLVED]

I'm writing a login script using php and mysql. I got it to work on my server about a week ago, and then I set up apache, php and mysql on my netbook so that I could take my code with me and test it. Now it doesn't work. My registration script doesn't write to the mysql database but has no errors. Here is register.php:
<?php
define("DB_SERVER", "localhost");
define("DB_USER", "root");
define("DB_PASS", "swordfish");
define("DB_NAME", "users");
define("TBL_USERS", "users");
$connection = mysql_connect(DB_SERVER, DB_USER, DB_PASS) or die(mysql_error());
mysql_select_db(DB_NAME, $connection) or die(mysql_error());
function addUser($username, $password)
global $connection;
$password = md5($password);
echo("adding $username,$password<br />");
$q = "INSERT INTO " . TBL_USERS . " VALUES ('$username', '$password')";
echo("query: $q<br />");
$result = mysql_query($q, $connection);
echo("$result<br />");
if (isset($_POST["reg"]))
addUser($_POST["username"], $_POST["password"]);
echo("<a href='index.php'>click here to login</a>");
?>
<html>
<head>
<title>Register</title>
</head>
<body>
<form method="Post" name="login">
<input type="text", name="username" /> Username<br />
<input type="text", name="password" /> Password<br />
<input type="submit" name="reg", value="Register" />
</form>
</body>
</html>
and here is the output (without the form):
adding lexion,6f1ed002ab5595859014ebf0951522d9
query: INSERT INTO users VALUES ('lexion', '6f1ed002ab5595859014ebf0951522d9')
Also, I tried manually adding the content to the database:
$ mysql -p -u root
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 9
Server version 5.1.42 Source distribution
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> users
-> INSERT INTO users VALUES('lexion', 'foo')
-> ^D
-> Bye
I would assume that I got something wrong with the last bit, but the php script seems like it should work. Does anybody know why it doesn't?

What is wrong with your PHP? Why do you think it is failing? An INSERT query doesn't return anything. Also, it's a good idea to specify which fields you are inserting into, unless you want to have to provide something for every field (tedious for tables with many fields with default values). eg:
$q = "INSERT INTO `" . TBL_USERS . "`(`username`, `password`) VALUES ('$username', '$password')";
As for your experiment with the mysql prompt; queries have to end with a semicolon. PHP is nice and hides that little detail from you.
edit: Also, you're echoing text out before the HTML starts. That won't produce valid HTML. I also noticed a few other things which I corrected; look at my comments:
<?php
define("DB_SERVER", "localhost");
define("DB_USER", "root");
define("DB_PASS", "swordfish");
define("DB_NAME", "users");
define("TBL_USERS", "users");
$connection = mysql_connect(DB_SERVER, DB_USER, DB_PASS) or die(mysql_error());
mysql_select_db(DB_NAME, $connection) or die(mysql_error());
function addUser($username, $password)
global $connection;
$password = md5($password);
// echo("adding $username,$password<br />"); - Don't echo stuff before HTML starts.
// Also, clean up user-supplied data before plugging it into a query unless you want to be vulnerable to SQL injection.
$cleanusername = mysql_real_escape_string($username, $connection);
$cleanpassword = mysql_real_escape_string($password, $connection); // Obviously you'd generally use some hashing algorithm like md5 or sha1 for passwords
$q = "INSERT INTO `" . TBL_USERS . "`(`username`, `password`) VALUES ('{$cleanusername}', '{$cleanpassword}')"; // The backticks tell MySQL not to interpret any text within as a keyword (good for field names, eg a field called `date`. The curly brackets tell PHP that the stuff within refers to a variable; it's nice as PHP knows exactly what the variable name is with no possible ambiguity.
// echo("query: $q<br />");
$result = mysql_query($q, $connection);
// echo("$result<br />"); - This won't do anything; in addition to INSERT queries not returning anything, the $result variable doesn't contain the results of the query, it's a pointer to them for use with mysql_result().
?>
<html>
<head>
<title>Register</title>
</head>
<body>
<?php
if (isset($_POST["reg"]))
addUser($_POST["username"], $_POST["password"]);
echo("<a href='index.php'>click here to login</a>");
?>
<form method="Post" name="login">
<input type="text" name="username" /> Username<br />
<input type="text" name="password" /> Password<br />
<input type="submit" name="reg" value="Register" />
</form>
</body>
</html>
<?php
mysql_close($connection); // Not strictly needed, as PHP will tidy up for you if you forget.

Problem with MySQL (SOLVED)

Hello everybody. I have a problem with my MySQL server. Just installed it, ant when i try to start it:
[root@localhost html]# /etc/rc.d/mysqld start
:: Adding mysql group [DONE]
:: Adding mysql user [DONE]
Installing MySQL system tables...
ERROR: 1062 Duplicate entry 'localhost-' for key 1
071223 22:35:05 [ERROR] Aborting
071223 22:35:05 [Note] /usr/sbin/mysqld: Shutdown complete

Does anybody has some ideas?

I have a huge problem, it seems I can't login to my own mysql server
mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
The first time I started mysqld I got the same error as above. The script that should create an account stopped. Because of this I didn't set a root password. I think I never set a root password, but somehow mysqld expects one.
Could someone help?
btw: my host in rc.conf is not localhost and it's corresponding with the hostname in /etc/hosts
-edit--
I just tried these steps: http://dev.mysql.com/doc/refman/5.0/en/ … sions-unix
But this also didn't work
--edit2--
Seems that there isn't a root account at all!

[SOLVED]Cannot install mysql correctly

Hi
If i try install mysql I get this errror:
chown: invalid user: 'mysql'
Cannot change ownership of the database directories to the 'mysql'
user. Check that you have the necessary permissions and try again.
error: command failed to execute correctly
Optional dependencies for mysql
perl-dbi
perl-dbd-mysql
Do i have to user called "mysql"? How can I install this package correctly?

What happens if you try to start the daemon after fixing the permissions (/etc/rc.d/mysqld start). Also check the mysql logs in /var/log should it fail.
If I try running daemon after fixing permissions still I see
/etc/rc.d/mysqld start
:: Starting MySQL Server [BUSY]
[FAIL]
Do you get this?
% grep mysql /etc/passwd
mysql:x:89:89::/var/lib/mysql:/bin/false
If not, try adding that line.
Where I have to add that line?
grep not shows anything.
