General :: Connecting To Mysql Database Remotely Via Port 3306 ?
Jul 23, 2011
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:
Everything default.Everything works nicely with one exception. I can't connect to MySQL from the network.nmapping localhost tells me 3306 is open but nmap from the outside shows only ports 22 and 111 open. To my knowledge I have no firewall, iptables -L gives an empty set.I have several similar installations on the same network without any problems of this nature.
How do I get mysql 3306 port to be seen on my network?
Here is my setup: ---Desttop - WIndows Vista Ultimate (192.168.0.101) --------VBox ------------Guest - Ubuntu 9.10 (Joomla CMS Development) (192.168.56.106) ---Server - Ubuntu 9.10 (192.168.0.100) --------VBox ------------Guest - Ubuntu 9.10 (Joomla Production) (192.168.56.104) ------------Guest - Ubuntu 9.10 (MySql Database) (192.168.56.105)
I can ping all OS from any OS, I can connect to a shares, I can connect to the web server. I can do a netscan and display the open ports and the services for those ports except for MySql. How do get MySql to showup, so I can connect to it from my Joomla CMS? I came from openSuse and I like how they have modules to do this automatically. What do I use with Ubuntu to get the same results?
I've been working and researching this for about a week now and I still haven't had any luck. Basically, I have been trying to open port 3306 to allow connections to my MySql server.
i've added the rule into iptables, saved and restarted that i've added the rule into my router. and I have removed "skip-networking" from the my.cnf file and added the blind address in, I'm trying to get this all to work on my LAN, but it doesn't seem to work, I've also restarted the entire server and then port scanned it from outside and inside the networking and it still tells me that 3306 is closed.
I did however i had some luck when I entered the Ip of the machine that would be sending data to the server but then PROFTPD stopped working and the port was open :/ im not really sure what ip should be in there but another thread from another forum said to enter the ip of the machine that mysql is installed on. so currently its 192.168.0.2 which is the static internal address of the server.
every machine on the network has a static ip and all the rules have been added to each firewall, i.e. server and router firewalls.
ill pop my "my.cnf" under this to see if anyone can find a mistake,
Code: # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # escpecially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing the socket location.
Im having a frustrating issue with my two machine cluster I setup using Conga. Everything was working great except now when lucci starts mysql the port (3306) is never opened to outside machines. I can do a "ps -ef | grep mysql" and see it running as well as login to mysql on the node it is running on - but an nmap of the machine does not show the 3306 port and I cannot login to mysql remotely and yes I turned off all iptables(iptables,ip6tables) and SElinux is disabled.What am I missing here? If I start mysql on my own (and it is using the same my.cnf as lucci is) it does show the port open and works perfect,t for some reason when lucci starts it, no dice
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 have an application running on a centOS machine that needs to access a database on a CentOS server. I granted access to all users with a certain user name and password.i opened up port 3306 as well with the following command: /sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPTbut whenever i try to connect from my machine i get an error:ERROR 2003 (HY000): Can't connect to MySQL server on '172.16.102.129' (113)I am using mysql version 5.0.77 on centOS 5.5.
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.
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.
How do I check port 3306 to see if it is being used? I am unable to get MySQL to run with a LAMPP 1.7.3a installedon Ubuntu 9.10. The Apache server and ProFTPD start fine.
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 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'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'd love a hint or two on the following problem. I've set up iptables rules to forward all connections to port 3306 to a non-standard mysql port on a remote server. This works, except that I need to deal with the loopback interface in a special way and I'm stuck.
Code: iptables -t nat -A PREROUTING -p tcp --dport 3306 -j DNAT --to 128.XXX.XXX.XXX:3197 iptables -A FORWARD -p tcp -d 128.XXX.XXX.XXX --dport 3197 -j ACCEPT iptables -t nat -A POSTROUTING -j MASQUERADE Since locally-generated packets will never hit the PREROUTING rule, you'll need to setup a near identical rule using OUTPUT to make it work. Here is what I've tried:
I get some trouble setting up good environment in linux.. i have problem regarding connecting php(under linux) to a sybase server(under windows),,, is there anyway connecting this two technologies?..
Specifically I'm looking for a native Linux program that is similar in functionality to Navicat or SQLYog. I.e. I need something good at editing data. Free would be best, but not essential.
I recently installed a portable WAMP server on my usb stick. Really nice, I can do some php programming on my girlfriend's windows7 laptop without installing anything on it.I also have a LAMP environnement on my linux computer.When I plug my usb stick on my linux box, I can easily mount -o bind /usbstick/wwwfolder ~/public_html and work on my php script from there.
But my question is, is there a way I could get the database from my usb stick's MySql server, to run on my linux MySql server? So I can modify data base schema from my Linux workstation, doing some INSERTS in some tables, and then plub my usb stick on the laptop and get my up-to-date database running from the portable environnement?I don't know where / how MySql stores its databases. Basically, I want to "mount" the database from the usb stick in my Linux' installed MySql server, without extracting and importing the data, so there is just ONE database used for BOTH environnement.
I posted a thread regarding a CD Base Application. I can run the program, but for some reason It does not seem to work properly.
For some reason in exits the program back to the command prompt. I am using the code from Linux programming 4th edition which you can get it from here...and in the folder ch08/app you will find all you need to create the CD database application.
I am not having any knowledge of mysql database & in my present jobs i have to solve problem on mysql database. need some commands which are used regularily in database.
I want to migrate a mysql databases from a old server to a new server ( Redhat ) , can advise what I need to do ,is it just copy all .frm , .MYI & .MYD files to new server will do ? or I need to do export and inport data ?
i need to update my mysql database from 5.0 for 5.1, i have several java application and php application running on that server, without disturbing the setup i need to upgrade the server can someone suggest a method of doing this
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've down loaded mysql database file and now I'm looking at adding it into a new dedicated server. Should I upload that sql file to the root folder I created for the domain and insert it with shh like that? If not where should I upload this mysql file to insert it to the new database. It's rather large so I have to use SHH Fir example if this is the code,
Code:
mysql -uUSERNAME -pPASSWORD DATABASENAME < MYDATABASE.sql where is that actual location of MYDATABASE.sql
I am not new to linux, but am to mysql. i run a website, on which i decided to put vpet, a virtual pet php thing. now in the instalation of this thing, it did not ask for an admin password. but it did come with a database. so i'm guessing the login is hidden in there. heres the question, i have phpmyadmin. how the heck do i read the database?
