Ubuntu :: Connecting To A Networked Mysql Daemon
Dec 6, 2010
I have installed Tomcat on one machine and MySQL on another. When I run tomcat on the same machine as Mysql and use 'localhost' in the jdbc url, I have no problem accessing mysql through jdbc. So my problem is accessing a remote mysql instance. I have granted privileges in the following way from the MySQL prompt:GRANT ALL PRIVILEGES ON mydatabase.* TO myusername @192.168.0.103 IDENTIFIED BY 'mypassword';
FLUSH PRIVILEGES;
Still I get :
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorEx ception: Access denied for user 'myusername'@'192.168.0.103' to database 'mydatabase'
sun.reflect.NativeConstructorAccessorImpl.newInsta nce0(Native Method)
sun.reflect.NativeConstructorAccessorImpl.newInsta nce(NativeConstructorAccessorImpl.java:57)
[Code]....
I have no idea whether this is a problem at the operating system level i.e. allowing networked hosts, or whether it is something to do with MySQL. I have commented out bindaddress and, on this version, there is no 'skip-networking' line to comment out.

My friend has a Windows 7 desktop with a large data hard drive which is set up to allow other users to connect to remotely, such that they have read and write access. To set up a connection from another Windows machine, it is as simple as right clicking in the My Computer window and selecting "New Network Connection", then entering the information requested.
The information my friend as given me is:
- The IP Address
- The Hard Drive's Name
- A Username and Password

I'm having problems connecting to the mysql database on my system. I first noticed this when I was trying to set up the program anymeal. I subsequently tried using MySQL Administrator (mysql-admin), but had no luck. It gives my the following feedback:
Code:
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Click the 'Ping' button to see if there is a networking problem. I press the ping button, and it seems to connect.

I'm trying to get mySQL Daemon to start when the machine starts up (and it requires root privileges to run). The command to startup would be
Code:
sudo /etc/init.d/mysql start however that would prompt for a password, and that would not be very well possible now would it? Now, if i try to start it up without being root, it will not start. So this is my problem, maybe someone out there would know a bit more about this than me.

I installed MySQL on my Ubuntu 10.04 desktop. As I need it only once a month I removed it from all runlevels but mysql is still running after boot up. "lsof" shows that it is running and listening for connections.
Code:
neo@ubuntu:~$ sudo lsof -i
[sudo] password for neo:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
sshd 927 root 3u IPv4 7819 0t0 TCP *:ssh (LISTEN)

In my system I installed Oracle enterprise linux.while installing I installed Mysql also.
I checked the version which is 5.0.15
After my installation,I am installing Bugzilla 4.0.at that time it's showing below
===========================================================
Checking for DBD-mysql (v4.00) found v3.0007
For MySQL, Bugzilla requires that perl's DBD::mysql 4.00 or later be installed. To install this module, run the following command (as root):
/usr/bin/perl install-module.pl DBD::mysql
===========================================================
I ran below command
#/usr/bin/perl install-module.pl DBD::mysql

I'm trying to install ispCP and i need to start mysqld but it won't seem to start. I'm somewhat of a nooblet to linux (have a year of VPS 'experience', but nothing too fance) so bear with me.
When i run "service mysqld start" it fails with the error: "MySQL Daemon failed to start."
I ran: "tail -n 30 /var/log/mysqld.log" and this is the output;

Dear all, I have system running LAMP and acting as a regular webserver.After running the setup for quite some months, I start having major issues:Symptoms:1. Applications do not respond neither from LAN nor WAN - SSH daemon, Apache, MySQL, FTP2. Network still seems to work for ping and port listeners3. Telnet is still successful for 21, 22, 80, 33064. Server has to be restarted manuallyTrying to find out the issue, I went through /var/log/ looking for major issues or warnings. But nothing seemed plausible to me to understand the issue - except I knew I was running out of disk space a few times.Not being able to identify nor replicate the issue, I replaced the hardware running 24x7 since quite a few years. Doing this, I migrated at the same time from OpenSUSE 10.1 to 11.3.The machine itself is behind a firewall and only the above mentioned standard ports are accessible

for some reason, which I have exhausted all my thoughts upon..
I have mysql 5.0.77
I just made an amendment to the auto_increment_increment variable.. from 10 to 1
Gone to restart mysqld (im on redhat FYI) and get the error:
'Timeout error occurred trying to start MySQL Daemon.'
It fails to stop, and obviously fails to start.
I have included below my 'my.cnf' file but I cant see any issues with it, and can't for the life of me think why there is something wrong.
If I ever come across an issue, I don't tend to ask but instead try and figure it out (usually with success) but this time.. I just cannot get my head around it..

I wrote a code in C to connect to MySQL by using mysql_real_connect function but I recieved error "Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)" (by using mysql_error function).

installed mySQL-server on the Ubuntu and configured it(i've made this lots of times). After that I installed mySQL-Admin and connected successfuly to the server. Tried some queries and worked fine. So, then I opened tcp 3306 for incoming and outgoing from anywhare. Went to my XP station and install mysql odbc driver, allowed tcp 3306 and tried to connect but I got an error 10061. So I decided to telnet my server with 3306 port and I got "connection failed".

I've been using ubuntu for quite a few years, and know the basics of databases. However, how to get them to talk to each other... Not so much.
I need to be able to connect to a MySQL database using Microsoft Access 20074. The database is going to be running on my server, which runs ubuntu server 10.10.
So far, I have installed MySQL server and libmyodbc. I took the deetails for the odbc.ini file from the ODBC ubuntu community page, so this is the current setup (database name is business):
Code:
[ODBC Data Sources]
odbcname = MyODBC 3.51 Driver DSN
[business]
[Code].....
When I try to connect using Access, I get "Server does not exist or access denied."

Well i have got a problem with connecting to a mysql database using php. I used this package "mysql-noinstall-5.1.44-win32.zip" and extracted it to c:mysql and added c:mysqlin to the PATH variable and used the following command in command prompt to start mysql: c:mysqlinmysqld --standalone
well mysql did start and everything went well accessing mysql in command prompt. Well under the database "mysql" in the table "user" i created a new user "php" with a password="****" and hostname = "localhost" but when i try to access this database with a following php routine:
And when i accesses it with my browser using localtost/test.php, all i get is "localhost" displayed on screen, "Connected to mysql" never gets displayed not i get any error..i am using windows 7(32-bit-ultimate)and mysql 5.1.44.

I have recently installed Java in my Ubuntu 9.04 environment so that I can teach myself Java. Basic Java programs work, but I am having trouble connecting to a MySQL database. I installed these packages using Synaptic Package Manager.
1.gsfonts-x11
2.java-common
3.odbcinst1debian1
4.sun-java6-bin
5.sun-java6-jdk
6.sun-java6-jre
7.unixodbc
After these packages were installed, I was not sure if I needed to do this, but I downloaded the MySQL connector from MySQL :: MySQL Connectors and installed in a directory called /home/mark/mysql/.
I then did "sudo gedit /etc/environment" and added a CLASSPATH to where I installed the connector:
Code:
I found an example Java program from Using JDBC with MySQL, Getting Started and stripped it down even further to test the MySQL connection.
This is the program I am running:
Code:
Could not find the main class: Jdbctest. Program will exit. I am new to Linux, Ubuntu, Java and MySQL, so I have probably left out something that is very obvious.

We are hoping to build a central database server so that we can take all the singular instances of mysql off our web servers and have the data stored in one place (we also run a number of syslogging servers that use mysql, netflow servers that use mysql, and many other servers that have mysql tables that we would like to consolidate as well). Now I have run into the problem that requires all the customer web sites to change the configuration for their connection to the mysql server from a local connection to a remote connection, which is something we are trying to avoid. I am wondering if there is a software suite or a function of mysql itself that allows you to present the remote database information as local databases to a server, allowing customer configurations to remain intact, as if the mysql server never moved off the local machine? Or a different question, can you configure mysql server to take local requests and forward them to a central mysql server?

Error: Can't connect to MySQL server on '192.168.1.120'(61)(code 2003)

I am getting this error when I try to connect to my MySQL database from a PHP page. "Fatal error: Call to undefined function mysql_connect() in /usr/local/htdocs/test.php on line 11" I have found instances on the Internet where other people had the same problem but from everything I've read, none of it appears to do anything for me.
I have read that I need the "extension=mysql.so" in my php.ini file and to uncomment it but it's not in there and I don't even have the "mysql.so" file. Many people have said to install the MySQL "devel" package, which I have also done and it is still not adding the file. I have also tried running the PHP ./configure again with the "--with-mysql". After all of these I still can't seem to get any further than I was when I found out I had a problem.

I think this goes here, but I'm not sure. I decided that XAMPP had been troublesome enough. MySQL never worked. So I decided to instal the LAMP stack offered by YaST. I went about installing it thinking that it would all work. But it seems that I was wrong. So I try to start mysql, and here's what I get:
Code:
the-matrix:~ # mysql start
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) or
Code:
the-matrix:~ # rcmysql start
