I am not able to start the MySQL server on my Windows system. When I tried in services.msc to run, I got this error:
Starting it through the XAMPP control panel does not work either:
Can you help me to solve this?
Open windows services (Start->run ->Services.MSC)
Find service with name "Mysql Server" and check path, it should be something like that:
"C:\Program Files (x86)\Parallels\Plesk\Databases\MySQL51\bin\mysqld.exe" "--defaults-file=C:\Program Files (x86)\Parallels\Plesk\Databases\MySQL\Data\my.ini" MySQL
Make sure that Mysql folder and executable file mentioned above exist by this path.
OR
Sometimes the file name of mysqld-nt.exe renamed to mysqld-nt.exe~ so rename it back to its original name and this may solve the problem.
Go to the path: C:Programs Files\MariaDB 10.2\data..
Lookout for my.ini file. Open the file and check the path for "datadir".
If that does not match to your installed directory then update it.
Your problem will be solved for sure.
I faced the same problem and solved it.
Just modify the registry editor value.
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/MySQL/ImagePath
I have heroku toolbelt installed on Windows7 (x64 HomeEd). When i'm trying to login to heroku, i recieve strange message about MySQL (though MySQL already works fine with all software installed):
Microsoft Windows [Version 6.1.7601]
(c) Microsoft Corp., 2009. All rights reserved.
C:\windows\system32>heroku login
"MySQL" is not recognized as an internal or external command,
operable program or batch file.
"MySQL" is not recognized as an internal or external command,
operable program or batch file.
C:\windows\system32>
Exactly like shown - two times. As I found, heroku.bat does not invoke MySQL at any step. I think that OS runs some script (a kind of autoexec) just before or in parallel with heroku.bat, but i can't find the way used to do this. This is confirmed by the fact that when i start the other bat files the same two messages about MySQL appears.
Can you help me find how that strange script is invoked?
Detailed research shown that the reason is MySQL component, named "MySQL Fabric 1.5.3 & MySQL Utilities 1.5.3 1.5". During installation MySQL added it's location to Path environment variable. This caused to break Path variable contents with "&" symbol and any invocation of Path variable cause error
It seems that at some point a script tries to call MySQL.exe and this file can't be found. To solve this problem you should add the Directory containing MySQL.exe to %PATH%. First make sure MySQL.exe is located on your system. If you are not sure where it is, start CMD, go to your root directory (CD \) end enter dir /S MySQL.exe. This will search your drive for the file and show you the path, where it can be found. Save the path somewhere.
Now that you know where the file is is, you have to add it's location to %PATH%. To do so enter setx PATH "<NEWPATH>;%path%;" where is the path to the directory containing MySQL.EXE. Dont forget ;%path%;, this is very important. If you don't put it there it wil mess up your %PATH%.
Close the console, open a new one and type heroku login. This should fix the problem.
Now if you are not interested in fixing the error and just want to know where it comes from, you should post the code of the batch file that is executed by calling heroku login.
Just remove the C:\Program Files (x86)\MySQL\MySQL Fabric 1.5 & MySQL Utilities 1.5\;C:\Program Files (x86)\MySQL\MySQL Fabric 1.5 & MySQL Utilities 1.5\Doctrine extensions for PHP\; from your path (It is breaking things up, it gets added during MySQL installation)and add the MySQL bin path. For me it is C:\Program Files\MySQL\MySQL Server 5.7\bin
I recently installed hadoop on my local ubuntu. I have started data-node by invoking bin/start-all.sh script. However when I try to run the word count program
bin/hadoop jar hadoop-examples-1.2.1.jar wordcount /home/USER/Desktop/books /home/USER/Desktop/books-output
I always get a connect exception. The folder 'books' is on my deskop(local filesystem). Any suggestions on how to overcome this?
I have followed every steps in this tutorial. I am not sure how to get rid of that error. All help will be appreciated.
copy your books file into your hdfs
and for the input path argument use hdfs path of your copied book file.
for more detail go through below link.
http://cs.smith.edu/dftwiki/index.php/Hadoop_Tutorial_1_--_Running_WordCount#Basic_Hadoop_Admin_Commands
There is a bit of confusion here, when you run the hadoop ... command then the default filesystem which it uses is the hadoop distributed filesystem hence the files must be located on the hdfs for hadoop to access it.
To copy files from the local filesystem to the hadoop filesystem you have to use the following command
hdfs dfs -copyFromLocal /path/in/local/file/system /destination/on/hdfs
One more thing if you want to run the program from your IDE directly then sometimes you get this issue which can be solved by adding the
core-site.xml and hdfs-site.xml files in the conf variable something like
conf.addResource(new Path("/usr/local/hadoop/etc/hadoop/core-site.xml"));
conf.addResource(new Path("/usr/local/hadoop/etc/hadoop/hdfs-site.xml"));
change the path above to the hdfs-site.xml and core-site.xml to your local path.
So the above arguments can also be provided from the command line by adding them to the classPath with -cp tag.
When I tried to source for a particular .sql file, namely 'metropolises.sql' that I created and saved previously from a database, the following error is displayed:
Failed to open file 'metropolises.sql', error: 2
Any idea what went wrong?
Assuming you mean that you are trying to use the source command in order to execute SQL statements from a text file, the error number given appears to be passed through from the POSIX layer.
Therefore, using this resource, we can deduce that the error value of 2 means "no such file or directory".
In short, you got the path wrong.
Try providing an absolute path, as it's not clear what the current working directory will be in the context of your MySQL server. You may be assuming that it's the working directory of your shell, but it's not obvious that we should expect this to be true.
Just use the absolute path of the file and then, instead of using backslashes, use forward slashes.
Example:
with backslashes : source C:\folder1\metropolises.sql
with forward slashes : source C:/folder1/metropolises.sql
IF YOU ARE USING MYSQL INSIDE DOCKER
Note that if you are running MySQL inside docker then you must first copy the dump into your MySQL docker environment. To do that follow the steps below
First, check and copy the container ID for your MySQL docker by:
sudo docker ps
Copy the SQL dump file into your container using:
sudo docker cp /path/to/sql/file.sql MysqlDockerID:/
This will copy the dump file into the docker root folder if you want to copy the file inside any other directory/path inside docker replace the '/' after 'MysqlDockerID:' with the path you want appropriate one.
Now to interact with MySQL inside a running container run the following command:
sudo docker exec -it MysqlDockerID bin/bash
Now connect to the MySQL using the terminal by:
mysql -u yourUserName -p
This will now ask you for the password. Enter the correct password to proceed.
List the databases available by:
show Databases;
This will list out the available databases
Assuming your database name where you want to import dump to is 'MyDatabase'. Switch to that using:
use MyDatabase
Now you can import the file by typing:
source file.sql
Remember the above command works if you have copied your file into your root folder (using step 2). If you have copied it to any other path make sure you use that same path instead
Related issue I had getting error 2 running source command: filename must not be in quotes even if it contains spaces in name or path to file.
It's probably the file path to your file. If you don't know the exact location of the file you want to use, try to find your file in Finder, then drag the file into Terminal window
mysql> SOURCE dragfilePathHere
I first reach to the file
c:\windows>cd c:\akura\Db Scripts
c:\akura\Db Scripts>mysql -u root -p root
mysql>\. EXECUTER_NEW_USER.sql
here EXECUTER_NEW_USER.sql my file name
I've had the same error on Windows.
I solved it with (after on cmd: mysql -u root):
mysql> SOURCE C:/users/xxx/xxxx/metropolises.sql;
Be sure you type the right file path
On my windows 8.1, and mysql 5.7.9 MySQL Community Server (GPL),
I had to remove the ; after the file path.
This failed: source E:/jokoni/db/Banking/createTables.sql;
This Worked: source E:/jokoni/db/Banking/createTables.sql
(without termination, and forward slashes instead of windows' backslashes in path)
If you are using vagrant ensure that the file is on the server and then use the path to the file. e.g if the file is stored in the public folder you will have
sql> source /var/www/public/xxx.sql
Where xxx is the name of the file
I got this error in mysql command line using this query:
source `db.sql`;
I changed the above to the following to make it work:
source db.sql;
On my Mac, this is the only solution worked for me.

1 - Download the .sql file and remember it's location.
2 - Open your mysql from command prompt or terminal.
3 - Create a database with the same name as that of the database present in the .sql file (create database your_database_name)
4 - Now exit out from the mysql command line client
5 - Now try and execute this command =>
mysql -u your_username -p your_database_name < your_sql_file_with_complete_location
example - mysql -u root -p trial < /home/abc/Desktop/trial.sql
here my .sql file is named trial and is present in the desktop, the database is also name trial
6 - You should now have your sql file imported to the corresponding mysql database.
I was having this issue and it turns out if you are using wamp server to run mysql, you have to use the file path within the wamp64 folder. So when the absolute path is: C:/wamp64/www/foldername/filename.sql
The path you have to use is:
www/foldername/filename.sql
May be the file name or path you are used may be incorrect
In my system i created file abcd.sql at c:\
and used command mysql> source c:\abcd.sql Then i got result
If you're on Debian 8 (Jessie) Linux, try to cd into the directory of the 'metropolises.sql'. Run mysql and execute SOURCE ./metropolises.sql;
Basically, try the relative path. I tried this and it works.
If you are running dockerized MySQL container such as ones from this official Docker Image registry: https://hub.docker.com/_/mysql/ You may encounter this issue as well.
For me it was because the file was located on a shared drive and it could not access, for some reason, to that path.
I cut the file and put it on my local drive in a path without spaces and it got resolved.
I got the same error when i used the command source and gave the sql file path by drag n dropping it.
Then I just had to remove those single quotes which appeared by default with drag and drop, a space before file extension and it worked.
soln:
source /home/xyz/file .sql ;(path and a space before file extension)
For Mac users, you can give the path as,
source /Users/YOUR_USER_NAME/Desktop/metropolises.sql;
*I have assumed that the file you need to source is in your desktop and the file name is metropolises.sql
If you type,
source metropolises.sql
then the file will be look in the default location,
/Users/YOUR_USER_NAME/metropolises.sql;
The solution for me was file permissions in Windows. Just give full control in the file to all users and it will work. After the import, get the permissions back to what it was before.
I had a problem on my Mac because one of the folder (directory) names in the path had a space in the name. BTW, the space was escaped by a \, but that was not understood by mySQL
solution - 1) Make sure you're in the root folder of your app. eg app/db/schema.sql.
solution - 2) open/reveal the folder on your window and drag&&drop in the command line next to keywork source (space) filesource. eg source User/myMAC/app/db/schema.sql
I get into this problem in my Xubuntu desktop. I fixed it by renaming all my files and folders so there is no space in the file path.
Passing the full path does not error, but if the folders have MySQL spaces it does not recognize the .sql file.
I have MySQL 8.0.21 on OS UNIX.
I've got the same error on Windows. I solved it running the code on MySQL command line
source c:\Users\xx\Downloads\data_file.sql
Remove spaces in the folder names of the path, It worked for my mac path.
(Eg: change the folder name MySQL Server 5.1 to MySQLServer5.1)
I also got the same message when I try from the MySQL console. However, when I open the command prompt and do the same steps it works.
C:\Users\SubhenduD>cd ../
C:\Users>cd ../
C:\>cd \xampp\mysql\bin
C:\xampp\mysql\bin>mysql -u -root

i want to use my mysql databases in weka in order to analysis data.
i download the mysql-connector-java-5.0.8-bin.jar and put that in weka folder in my program Files folder, and add this path to system variable path, but when i open the weka explorer and click the openDB, i don't know what should i write in the url textbox,
i don't know completely what should i do?
the error that i saw is:
problem connecting to database:
no suitable driver found for!
please give me a total guidance, thanks in advance.
add mysql-connector-java-5.1.12-bin.jar to CLASSPATH .
or put it in weka folder, navigate to weka installation folder and run command :
%java_home%/bin/java -Xmx300M -cp ".;weka.jar;mysql-connector-java-5.1.12-bin.jar;" weka.gui.GUIChooser
then click open DB and
fill in the proper user+password
put the url: jdbc:mysql://localhost:3306/DATABASENAME
Click Execute. The result window should show the results now.
For Weka 3.7.10, the classpath system environment variable is not took into account (at leat under Windows 7). The only working approach for me was to modify the RunWeka.ini file from the Weka installation folder as follows: the cp= setting was modified to:
cp=%CLASSPATH%;d:/Programs/jdbc/mysql-connector-java-5.1.26/mysql-connector-java-5.1.26-bin.jar
whereas only the %CLASSPATH%; setting was originally provided. Does not make much sense, but in worked.
find some introduction to WEKA and the environment variable:
http://weka.wikispaces.com/CLASSPATH
Copy mysql-connector-java-X.X.XX-bin.jar to /usr/share/java/
unizip /usr/share/java/weka.jar
edit: /usr/share/java/weka/experiment/DatabaseUtils.props
add:
jdbcDriver=com.mysql.jdbc.Driver
jdbcURL=jdbc:mysql://localhost:3306/test (with your server)
add shell
export CLASSPATH=/usr/share/java/mysql-connector-java-X.X.XX-bin.jar:
export CP=/usr/share/java/mysql-connector-java-X.X.XX-bin.jar::/usr/share/java/:/usr/shared/java/weka.jar
execute weka:
java -cp $CP -Xmx500m weka.gui.explorer.Explorer
