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'm writing a bash script to do some db stuff. New to MySQL. I'm on Mac and have MySQL installed via homebrew.
Am using username "root" right now and there isn't a pw set. I included the pw syntax below just to help others out that may have a pw.
My goal is to have mysql commands be as "clean" as possible in my bash script
Not a hige deal, but would like to do this if possible.
Example
# If I can do it without logging in (*ideal)
mysql CREATE DATABASE dbname;
# Or by logging in with - mysql -u root -pPassword
CREATE DATABASE dbname;
# Instead of
mysql -u root -pPassword -e"CREATE DATABASE dbname";
Tried to simplify it. I have a handful of things I gotta do, so would rather keep my code cleaner if possible. I tried logging in with the bash script, but the script stopped once logged into MySQL and didn't run any commands.
Another option I was considering (but don't really like) would be just to keep username and pw string in a var and call it for every commmand like so
# Set the login string variable
login_details="-u root -p password -e"
# example command
mysql $login_details"CREATE DATABASE dbname";
So any ideas?
Write a new bash script file and run this file after putting all your commands into it. Don't forget to give right username and password in your bash script.
For bash script:
#!/bin/bash
mysql -u root -pSeCrEt << EOF
use mysql;
show tables;
EOF
If you want to run single mysql command.
mysql -u [user] -p[pass] -e "[mysql commands]"
Example:
mysql -h 192.168.1.10 -u root -pSeCrEt -e "show databases"
To execute multiple mysql commands:
mysql -u $user -p$passsword -Bse "command1;command2;....;commandn"
Note: -B is for batch, print results using tab as the column separator, with each row on a new line. With this option, mysql does not use the history file. Batch mode results in nontabular output format and escaping of special characters. -s is silent mode. Produce less output. -e is to execute the statement and quit
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

How to execute a MySQL command from a shell script?
Specifying the --password argument
mysql -u root --password=my_mysql_pass db_name
Safer using a bash variable
mysql -u root --password=$MYSQL_PASS db_name
I am trying to run MySQL query on remote machine with this command:
ssh user#192.168.2.26 "mysql -uroot -proot -e \"use test";""
I am not able to use that database.
Please suggest a working command.
Try this:
mysql -h host -u root -proot -e "show databases;";
Try this:
ssh root#host "mysql database -e 'query to run on table_name; more queries to run;'"
Same can be done with user#host if that user has permission to execute SQL queries let alone launch mysql in general. Using -e is the same as --execute, which will run whatever you put within the trailing quotes (single or double) and quit. The standard output format would be the same as you would see using --batch.
MySql seems to have a special command line syntax which includes the database.
mysql -u user -p -e 'SQL Query' database
This documentation is rather old but I got it to work
http://www.cyberciti.biz/faq/run-sql-query-directly-on-the-command-line/
Final working command with ssh:
ssh user#host "mysql -u user -e 'show tables;' databasename"
This ended up working for me in a bash script:
query='USE [database]; SELECT ...'
mysql='mysql -u [username] -p[password] -e '"'""$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 have this command in linux
mysql -u xyz -p -e "show databases"
Where, the user "xyz" doesn't exist. When it asks for password
if i don't give any password it doesn't give error message or a non-zero value when i run echo $? command.
if i give a password it gives error message
Any reason why? And any suggestions what I have to do to get an error message for this command?
Try:
mysql -u xyz -pYourPassword -e "show databases"
Or:
mysql -u xyz --password=YourPassword -e "show databases"
I guess there is no other way but to run-
mysql -u xyz -p -e "use mysql"
as mysql database doesn't exist for non existing users.
i found this code but do not quite understand what the command is doing.
sudo -u test-user mysql -U test_traffic traffic < ./phoenix/data/sql/lib.model.schema.sql
i know the last part is using lib.model.schema.sql to create the tables and fields
the first part i dont quite understand: sudo -u test-user mysql -U test_traffic traffic
i know the command sudo and mysql
please explain?
thanks
Let's look at it bit by bit. Firstly the format
sudo -u username command
is an instruction to run command (which might be simple or complex) as the user username. So in your example, you are running the mysql command as the user test-user. You should note that this includes all the parameters to the mysql command - that's the entire rest of the line.
The command
mysql -U test_traffic traffic < ./phoenix/data/sql/lib.model.schema.sql
appears corrupt (certainly running it on 5.0.51a fails). It would make sense if the -U was a -u which would indicate that that the command was to be executed for mysql user test_traffic. If it was a -u you would then have an instruction to import the sql file into the traffic database.
So the combined instruction says, import the lib.model.schema.sql file into the database test_traffic using the mysql user test_traffic and executing the entire command as if you were logged-in as the user test-user.
Try Below steps for mysql:
mysql > -h hostname -u username -p password
mysql > use databasename;
mysql > source path/to/scriptfile
If you want to inject theschema.sql file into your database, with a shell script, simply use :
mysql -h [host] -u [username] -p[password] -D [database] < your_file
If you want to dynamicly tell which file should be loaded, replace your_file by $1 and pass the name of the file as an argument to your script.
Take care also to the -p option. There is no space between the -p and your password.
