In a simple script like this one:
set -x
# Check if db exists, if not we make it, make user, give privileges
if ! mysql -u root -p -e "use $db" 2>/dev/null; then
c1="CREATE DATABASE $db"
c2="GRANT ALL PRIVILEGES ON ${db}.* to '$username'#'localhost' IDENTIFIED BY '$password'"
c3="FLUSH PRIVILEGES"
mysql -u root -p -e "$c1; $c2; $c3"
else
echo 'DATABASE ExISTS, ABORTING'; exit $DB_EXISTS
fi
I am asked each time, bash sees mysql command, for my root credentials.
Is there a way to avoid that, so that once entered the root password, all
additional mysql commands execute seamlessly?
Try looking into adding password to ~/.my.cnf
[client]
user = root
password = XXXXXXXX

I want to run MySQL query from bash script to create new user:
mysql -u root -p$dbpass -e "GRANT ALL PRIVILEGES ON appdb_${BUILD}.* TO appuser#localhost IDENTIFIED BY 'somepass'"
Where $BUILD variable is set to a number, for example 15, so final query should look like this:
mysql -u root -p$dbpass -e "GRANT ALL PRIVILEGES ON appdb_15.* TO appuser#localhost IDENTIFIED BY 'somepass'"
But... in directory where script is and is run there is a tar archive with same name as database, so query becomes like this:
mysql -u root -p$dbpass -e "GRANT ALL PRIVILEGES ON appdb_15.tar.gz TO appuser#localhost IDENTIFIED BY 'somepass'"
I guess this happens because there is a match, but changing file name is not an option. Moving script to other directory is not allowed too.
I tried to escape dot with backslashes (appdb_${BUILD}\.*) - nothing changed.
How I can fix this?
There is nothing wrong with your approach and it is working in my case. See below. Can you tell us what is the error that you are getting so that we can help you?
[root#cloud mysql]# ls
appdb_15.tar.gz test.sh
[root#cloud mysql]# cat test.sh
#!/bin/bash
BUILD=15
# First Method
mysql -u root -ptest -e "GRANT ALL PRIVILEGES ON appdb_${BUILD}.* TO appuser#localhost IDENTIFIED BY 'somepass';"
# Second Method
mysql -u root -ptest <<EOF
GRANT ALL PRIVILEGES ON appdb_${BUILD}.* TO appuser1#localhost IDENTIFIED BY 'somepass';
select user, host from mysql.user where user like 'appuser%';
EOF
[root#cloud mysql]# ./test.sh
user host
appuser localhost
appuser1 localhost
EDIT 1:
I forgot to mention that this is definitely not a bash issue.
EDIT 2: Changed the build variable to 15 from 5.
I am writing a script that will run on a Ubuntu 16.04.1 server. The purpose of the script is to install a wordpress site on the server. I took most of my scripting from this site.
I am trying to create and grant permissions on the database, however my script stops when I enter a mysql environment using mysql -u root -p. As well, variables created in the bash environment are not carried over to the mysql environment. Here is my script for this section.
echo "Please enter the Name of the Database(please make name relevant)"
read -p DBNAME
echo "Please enter the Name of the Database User(Please document username)"
read -p DBUSER
echo "Please enter a Database password(Please document password)"
read -p DBPASSWORD
a=\'
b=$a$DBPASSWORD$a
f='CREATE DATABASE '$DBNAME' CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci'
g=$a$f$a
c='GRANT ALL ON '$DBNAME.*'TO '$DBUSER'#localhost'' IDENTIFIED BY '$b
d=$a$c$a
mysql -u root -p -e $g
mysql -u root -p -e $c
mysql -u root -p -e "FLUSH PRIVILEGES"
Any help integrating the environment changes together would be great
When defining f and c use double quotes. Single quotes don't allow your variables to expand.
You log the user in as root to mysql, but don't supply a password, so it will prompt. Perhaps ask for the root password as well.
Perhaps something like the following would do the trick:
echo "Please enter the Name of the Database(please make name relevant)"
read -p DBNAME
echo "Please enter the Name of the Database User(Please document username)"
read -p DBUSER
echo "Please enter a Database password(Please document password)"
read -p DBPASSWORD
echo "Please enter your database's root password"
read -p DBROOTPASSWORD
a=\'
b=$a$DBPASSWORD$a
f="CREATE DATABASE '$DBNAME' CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci"
g=$a$f$a
c="GRANT ALL ON $DBNAME.* TO $DBUSER#localhost IDENTIFIED BY "$b
d=$a$c$a
mysql -u root -p"$DBROOTPASSWORD" -e $g
mysql -u root -p"$DBROOTPASSWORD" -e $c
mysql -u root -p"$DBROOTPASSWORD" -e "FLUSH PRIVILEGES"
So I want to pipe my netstat output into a mysql database
The plan is to make it a continuous crontab event. That way I can store that data and use it elsewhere easily.
I figured before I could figure that part out though I needed to figure out how to run a SQL Command from terminal.
It seems pretty straight forward
sudo mysql -u username -pMYPassword -e "SQL COMMAND"
This however doesn't work...
When I run this it prints the MYSQL Help
When I run this though
sudo mysql -u username -p -e "SQL COMMAND"
everything works perfect, it just prompts me for a password
Now I don't know if it makes a difference or not but my DB password does have exclamation points in it. It is also over 15 chars long
Could either of these be an issue?
mysql -u user -p -e 'SQL Query' database
Where,
-u : Specify mysql database user name
-p : Prompt for password
-e : Execute sql query
database : Specify database name
So the option -p is a PROMPT, the password need not to be linked, but to be separated from it:
sudo mysql -u username -p'PassWord' -e 'SELECT COUNT(*) FROM my_table'
EDIT: If your real password contains special characters, you need to escape them.
Maybe try : sudo mysql -u username -p'MYPassword' -e "SQL COMMAND"
Or : sudo mysql -u username --password=MyPassword -e "SQL COMMAND"
I am trying to run MySQL query on remote machine with this command:
ssh user#192.168.2.26 "mysql -uroot -proot -e \"use test";""
I am not able to use that database.
Please suggest a working command.
Try this:
mysql -h host -u root -proot -e "show databases;";
Try this:
ssh root#host "mysql database -e 'query to run on table_name; more queries to run;'"
Same can be done with user#host if that user has permission to execute SQL queries let alone launch mysql in general. Using -e is the same as --execute, which will run whatever you put within the trailing quotes (single or double) and quit. The standard output format would be the same as you would see using --batch.
MySql seems to have a special command line syntax which includes the database.
mysql -u user -p -e 'SQL Query' database
This documentation is rather old but I got it to work
http://www.cyberciti.biz/faq/run-sql-query-directly-on-the-command-line/
Final working command with ssh:
ssh user#host "mysql -u user -e 'show tables;' databasename"
This ended up working for me in a bash script:
query='USE [database]; SELECT ...'
mysql='mysql -u [username] -p[password] -e '"'""$query""'"
ssh [username]#[server] -t "$mysql"
If you want to make it more safe then add a prompt for the password instead of storing it somewhere potentially unsafe.
This worked for me after a few tests (basically same answer as #King-Wzrd):
ssh -t kom "mysql -uroot -p -e 'show databases;'"
ssh -t kom "mysql -uroot -p < /home/ling/websites/jin_test/.deploy/tmp.sql"
The "trick" was the quotes around the command.
The -t option allows for prompting password interactively via the remote shell.
The kom here is just a ssh config identifier defined in my ~/.ssh/config file (see more here: https://www.cyberciti.biz/faq/create-ssh-config-file-on-linux-unix/).
Running this from my Host environment against MySQL within my Homestead VM produced a nice result... although I did have to set the root password from within the VM first in order for it to work.
ssh vagrant#192.168.10.10 mysql -h localhost -u root -p -e "'SELECT * FROM user;' mysql";
I'm under VPN and I don't have SSH access to remote server.
I can connect to remote database by console
mysql -u username -p -h remote.site.com
Now I'm trying to clone the remote database to local computer
mysqldump -u username -p -h remote.site.com mysqldump | mysql -u root -ppassword webstuff
And I've got error
mysqldump: Got error: 1045: Access denied for user 'webstaff'#'10.75.1.2'
(using password: YES) when trying to connect
How to copy mysql database from remote server to local computer?
Assuming the following command works successfully:
mysql -u username -p -h remote.site.com
The syntax for mysqldump is identical, and outputs the database dump to stdout. Redirect the output to a local file on the computer:
mysqldump -u username -p -h remote.site.com DBNAME > backup.sql
Replace DBNAME with the name of the database you'd like to download to your computer.
Check syntax and execute one command at a time, then verify output.
mysqldump -u remoteusername -p remotepassword -h your.site.com databasename > dump.sql
mysql -u localusername -p localpassword databasename < dump.sql
Once you've matched all passwords, you can use pipe.
Often our databases are really big and the take time to take dump directly from remote machine to other machine as our friends other have suggested above.
In such cases what you can do is to take the dump on remote machine using MYSQLDUMP Command
MYSQLDUMP -uuser -p --all-databases > file_name.sql
and than transfer that file from remote server to your machine using Linux SCP Command
scp user#remote_ip:~/mysql_dump_file_name.sql ./
This can have different reasons like:
You are using an incorrect password
The MySQL server got an error when trying to resolve the IP address of the client host to a name
No privileges are granted to the user
You can try one of the following steps:
To reset the password for the remote user by:
SET PASSWORD FOR some_user#ip_addr_of_remote_client=PASSWORD('some_password');
To grant access to the user by:
GRANT SELECT, INSERT, UPDATE, DELETE, LOCK TABLES ON YourDB.* TO user#Host IDENTIFIED by 'password';
Hope this helps you, if not then you will have to go through the documentation

Copy mysql database from remote server to local computer
I ran into the same problem. And I could not get it done with the other answers. So here is how I finally did it (yes, a beginner tutorial):
Step 1: Create a new database in your local phpmyadmin.
Step 2: Dump the database on the remote server into a sql file (here I used Putty/SSH):
mysqldump --host="mysql5.domain.com" --user="db231231" --password="DBPASSWORD" databasename > dbdump.sql
Step 3: Download the dbdump.sql file via FTP client (should be located in the root folder)
Step 4: Move the sql file to the folder of your localhost installation, where mysql.exe is located. I am using uniform-server, this would be at C:\uniserver\core\mysql\bin\, with XAMPP it would be C:\xampp\mysql\bin
Step 5: Execute the mysql.exe as follows:
mysql.exe -u root -pYOURPASSWORD YOURLOCALDBNAME < dbdump.sql
Step 6: Wait... depending on the file size. You can check the progress in phpmyadmin, seeing newly created tables.
Step 7: Done. Go to your local phpmyadmin to check if the database has been filled with the entire data.
Hope that helps. Good luck!
Note 1: When starting the uniformer-server you can specify a password for mysql. This is the one you have to use above for YOURPASSWORD.
Note 2: If the login does not work and you run into password problems, check your password if it contains special characters like !. If so, then you probably need to escape them \!.
Note 3: In case not all mysql data can be found in the local db after the import, it could be that there is a problem with the mysql directives of your dbdump.sql
Better yet use a oneliner:
Dump remoteDB to localDB:
mysqldump -uroot -pMypsw -h remoteHost remoteDB | mysql -u root -pMypsw localDB
Dump localDB to remoteDB:
mysqldump -uroot -pmyPsw localDB | mysql -uroot -pMypsw -h remoteHost remoteDB
C:\Users\>mysqldump -u root -p -h ip address --databases database_name -r sql_file.sql
Enter password: your_password
This answer is not remote server but local server. The logic should be the same. To copy and backup my local machine MAMP database to my local desktop machine folder, go to console then
mysqldump -h YourHostName -u YourUserNameHere -p YourDataBaseNameHere > DestinationPath/xxxwhatever.sql
In my case YourHostName was localhost. DestinationPath is the path to the download; you can drag and drop your desired destination folder and it will paste the path in.
Then password may be asked:
Enter password: xxxxxxxx
