I have created a Rails application and hosted it on EngineYard. Now I want to manually insert one record into my database.[Database: MYSQL]
How can I access EngineYard's database from my local machine?
P.S: I have came across this article and I can't infer proper explanation from that. I have even searched for video tutorials and can't find any. Please help me.
Atlast I got the answer for my question after spending a lot of time on this and getting support from EngineYard team.
First you need to create a local SSH Key Pair by following this article.
Next you need to add that SSH Key (something like id_rsa.pub or id_dsa.pub) at https://cloud.engineyard.com/keypairs
Then you need to execute this command in your local terminal
ssh deploy#ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com
where deploy is the common and default username for your database and ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com is your hostname

So I am developing an app that I want to let include server interaction. I have installed MySQL server and MySQL Workbench. I am able to query my data base locally from Java. such as local host. but when I change the query correctly, to reference the IP of my server and not "localhost", I am unsuccessful both on my server and separate machine. I have pinged my server from my another machine successfully. I have configured user accounts on MySQL workbench in almost every way possible. I have done a lot of googling with little success.
I am 19 and just starting to learn SQl now. It'sn ot a big part of my project. I am sorry if this sounds like a basic question, but google has gotten me no where and I am really eager to publish my app xP . So I would really appreciate the help or even a basic guide as to what I may be doing wrong.
Most likely, this is because you did not yet assign user permissions for remote computers. You'd have to use something like tyhe following:
GRANT SELECT ON myDatabase.*
TO myUser#’mycomputers.ip.address’ IDENTIFIED BY ‘my_password’;

First ever Stack Overflow post, thanks for your time. Any constructive criticism on how to post better, please just let me know. I have done a search on my query and have found similar posts, but I was unable to use the information within them to resolve my problem.
I have created a mysql database using the terminal window in my Ubuntu system (which I am also new to, having been a lifelong windows user). I used the following code in the terminal window:
$ mysql -u root -p
Then once in mysql, I did the following
CREATE DATABASE securities_master;
USE securities_master;
I created a user and tables in the database using some other code, that doesn't seem relevant here, so I won't bother posting. However, I then decided I would like to take a look at the tables in the database, so I downloaded an SQLite browser. It was at this point that I realized I could not find my database file.
I tried to find the answer on previous stack overflow posts, and tried the suggestions of:
locate sqlite
locate .db
locate .sqlite
locate securities_master
But unfortunately, none of these showed the file I was looking for. The only place I can think of would be what is called the 'root' directory in my computer, but the Ubuntu file manager system won't let me view it because it says I don't have permissions. Is this where it might be?
Could someone shed some light on where I might be able to find this file/database? I know it is definitely there because if I try to CREATE it again, I get the message that it can't because it already exists.
Thanks again.
sqlite and mysql are two different databases. You can't use sqlite on a mysql database. sqlite is a single-file database, in which users just open the file and read and write to it, while mysql is a more traditional relational database system with a server and a client, where the server manages the database (which is generally in a directory of files), while the client just connects to the server.
Where the mysql database is located my depend on your system, but it's usually in /var/lib/mysql. You can look in /etc/mysql/my.cnf for the configuration file, which should have a datadir option that refers to where the actual data for the database is stored.
You can check my.ini file to see where the data folder is located.
Usually there is a folder {mysqlDirectory}/data
MySQL data storage:
Commands.frm
Commands.myd
Commands.myi
The *.frm files contain the table definitions. Your *.myi files are MyISAM index files. Your *.myd files contain the table data.
as mentioned in the answer before mine, mysql and sqlite are two different systems.
You mention you used the cmd line mysql to create the database and then wanted to view the tables. If you're simply trying to see which table are created, in the same command line you used to Create the database you can run show tables;
If you're after a GUI for this, we'd need a bit more context. Is this ubuntu system a remote server, or are you using the desktop version?
You say you're a long time windows user, If you're using windows locally, I personally like SQLWorkbench for accessing my remote mysql servers.
EDIT: I just re-read your post and realised you're using local ubuntu desktop so me mentioning remote was silly, my bad! However, SQLWorkbench does have a ubuntu version at https://dev.mysql.com/downloads/workbench/
I am working at a company that has some CRM software running in a remote Windows XP server that uses a SQLAnywhere 9 db to store its data; I have access to this remote server with an administrator account.
I would like to extract the db into a .sql file so that I can run the db locally on my machine without affecting the running db in the server (since it is key for the company's day to day operation).
The reason I need this is that we are going to test some BI Software and we need data from this database to test it, but we don't know the structure of the database since the developers of the CRM software didn't give us any documentation on it. So we need to have the database locally so that, without affecting the running CRM, we can:
understand the structure by looking at the DDL
make queries to it to get sample data
I researched a bit, and the most common solution to my problem was to use dbunload on the remote server to unload the db into a reload.sql file that contained what I needed. But most tutorials on the subject mention that I have to stop the db first (which would be catastrophic). If this is the only option, then I guess I am willing to do it on the weekend when the CRM is not used, but I wanted to know if there was another solution first.
If there is no other solution, can you point me to where I can find the proper and safer way to do this?
I have researched a lot, but prior to this day I have never even heard of SQLAnywhere, so I really need all the help I can get. My main concern is doing something that impacts negatively the CRM software.
Thank you.
You can run dbunload across the network, you just have to tell it to do an "external" unload. The default is to do an internal unload which would only work from the machine where the database server is running.
I don't have SQL Anywhere 9 documentation right now to look up the exact switch, but dbunload -? should show you all the possible switches.
Edit:
-an will create a new database and load the data and schema from another data
-xi switch will do external unload and internal reload.
-c parameters to connect to your remote database
I'm trying to migrate a web site to friend's server. The site uses MySQL, but he didn't previously have it set up. He's installed the package now and suggested that I could run my own instance of it. I'm at a loss for how to do so. Is it even possible? If so, how?
Some relevant information:
The OS in use is CentOS 5.9
Using MySQL 5.0.95
I only need the DB to be read locally via PHP when serving my site.
I have no root privileges on this system (although a full shell), but am close friends with the owner/administrator if that's necessary.
To clarify:
It's the daemon that I want to run my own instance of. So I guess what I want to know is if it's possible to have multiple users on the system running their own instances of mysqld containing different databases.
All I need this for is serving a web page. If I have to break down and switch to a pseudo-database using CSV files I will, but I'd much rather stick to MySQL if I can.
If MYSQL is setup on that machine yes you can run your own instance of it.
You can have it set up and your site given its on Database within that MYSQL instance and that specific MYSQL account can be used to access the tables etc. involved with your website.
Now if he is only putting MYSQL on the machine then having you set everything up you will just need an account for MYSQL and from ther eyou can get in and just create all the needed items that will allow your site to fully function.
EDIT
In response to your comment. You can you just can't clog the same port or have configurations that conflict each other. As long as it won't be to much of a performance hit and you configure a different user to start each instance you should be able to do Something like this.
I installed MySQL on an EC2 instance and need to get some information about that database so I can setup pligg on it.
The info it needs are: Database Name, Username, Password, Database Server and Table Prefix. Is there a simple way to retrieve this information? I assume I need to use PuTTy but I couldn't find specific info on it.
Thanks
The database server is most likely to be localhost and the rest are values that you must set. The docs for whatever application you are installing should give a tutorial on how to create these.
You might find phpMyAdmin useful if the application provides a SQL script to run and you don't want to use the command line.
