Ubuntu :: Java Installation Error Connecting To MySQL Database
Jul 2, 2009
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.
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.
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've setup a CentOS apache web server, and loaded a site onto it. The site previously was functioning under windows xp (before I "stepped in") and wamp. What I did was copy the site in /var/www, reconfigure the httpd.conf (DocumentRoot /var/www/site, etc). Although when I try to open the webpage I get this error: Database Error: Unable to connect to the database:The MySQL adapter "mysql" is not available.
I've got a database and I've got a Java program that I'm programming in Netbeans that is suppose to run queries to the database. how I will set about to connect the database with the Java program so that I can run the queries?
It is very important that I learn how to do this, else I am forced to go back to XP in order to finish this project on time.
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.
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?
I'm new to linux, and setting up the mysql database server.
Here are my situation:
OS: CentOS 6 mysql version: 5.5
I tried to use MySQL Administrator to connect to my database on the host 192.168.1.120 and my computer is under the same network with ip: 192.168.1.105
But it shows the error msg: Could not connect to MySQL instance at 192.168.1.120
Error: Can't connect to MySQL server on '192.168.1.120'(61)(code 2003)
On the server side I've tried:
Code:
skip_networking is off and I've set the port for it.
When I check the process in OS:
Code:
When I try netstat:
Code:
I thought it's the problem of firewall, so I have check it also:
I have installed Mysql in Ubuntu 9, for the use of roundcube database.After installing iam getting the error like this
* Stopping MySQL database server mysqld [ OK ] * Starting MySQL database server mysqld [ OK ] * Checking for corrupt, not cleanly closed and upgrade needing tables.
So because of this in the roundcube configuration its giving the error message that MYSQL is not installed. So Kindly give me a idea how to solve this.
I upgraded a system from 10.3 to 11.4 and I get the following error when trying to run mysql:
Will update MySQL now, if you encounter any problems, please read following file: /usr/share/doc/packages/mysql-community-server/README.SuSE Log files inconsistency, please merge following files manually: /var/lib/mysql/mysqld.log /var/log/mysqld.log
How can I correct this? Mysql will not start so I can not run any of the utilities.
while creating a new database iam facing the below problem
mysql> create database auto-download-gta; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-download-gta' at line 1
I'm try to setup a database server using mysql, the server starts fine, and I can access it using the built in mysql client via console (adding databases and tables works fine), but the problem is... I always get a connection refused error whenever I access the database outside the built in mysql client (example, if I write a code that connects to mysql). So, I tried execute an nmap command and the only ports open are these ports:
[Code]....
there's no 3306 for mysql... I'm thinking that the firewall is just blocking the port that mysql is using, but my question is, how could the built in client connect to the server if there's no open port for mysql server? Don't clients usually access a servers through ports?
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 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).
I also did the following things: in mysql I typed 'SHOW VARIABLES LIKE '%SOCKET%'', it returned /var/lib/mysql/mysql.sock I typed 'mysql_config --socket' in shell, it returned /var/lib/mysql/mysql.sock I modified /etc/my.cnf file
I follow instruction on how to install ISPConfig2 in CentOS 5.3. CentOS 5.3 ISPConfig 2 At part 10. MySQL(5.0), I stuck with an error. Said that "Host is not allowed to connect to this MySQL server. What is the problem? Why not allowed?
Iam always working from 1 machine to another even with my laptop which i dont place all my data some of which in some machine, iam always constantly saving all my files specially my MYSQL database files which have grown in size, Is there a ways I can just copy & paste my MYSQL database? like in MSACCESS.
I am trying to connect to my mysql database using php but I am getting the error "Fatal error: Call to undefined function mysql_connect()".
I checked phpinfo() and there is no reference to MySQL. I believe this means that my install of PHP doesn't support MySQL. Do I need to uninstall and reinstall with a version of PHP with MySQL support? If so how should I do this and how do I get a version of PHP that supports MySQL?
due to some issues i uninstalled openjdk shipped default on my opensuse 11.3 and installed jdk 1_6_21 from a .bin file. Its installed to usr/java/jdk.The mysql connector is also present in the same but running a java program that connects to mysql gives me the errorjava.sql.SQLException: Unknown initial character set index '192' received from server. Initial client character set can be forced via the 'characterEncoding' property.the code i tried is
import java.sql.*; import java.io.*; class mysql_conn_tester
i'm trying to create a database with the mysql that came with the suse installation, my problem is that i can't get mysqladmin to work it spits out this: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2)' Check that mysqld is running and that the socket: '/var/run/mysql/mysql.sock' exists! So I'm stuck at square one php info() seems ok with the installation and the installed client connects to my remote DB ok. I checked the server with ps -ef | grep mysqld and I get the following:
Which doesn't really mean a lot to me but looks ok, anyway my question boils down to does anyone have any obvious ideas of what I'm doing wrong or is, as others have hinted, suse's mysql installation is broken?
i'm not the most knowlegable person but i have successfully installed mysql in the past. but now that i am attempting to install it again i'm getting this error during installation. has anyone seen this before?
mysql error: *Starting MySQL database server mysqld [fail] invoke-rc.d: initscript mysql, action "start" failed. dpkg: error processing mysql-server-5.0 (--configure): subprocess post-installation script returned error exit status 1
What commands can be used to install software such as "phpMyAdmin" to Fedora? As I am setting up Apache in Fedora. How to install "phpMyAdmin" and setup phpMyAdmin, so that I can use internet explorer to manage the phpMyAdmin to configure the MySQL database remotely.
I am now using SLES11. My web server now error mysql. However, when I restart mysql using "rcmysql restart" the message display:
Restarting service MySQL Shutting down service MySQL done Starting service MySQL done
but when I start to access via browser using my name virtual host (url) the message display "Error establishing a database connection"
when I go to mysql using command "mysql" the message display" ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)
After that I try to edit file mysql.sock but on the bottom of file display message (permission denied)
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.
