I have a ton of users on many different MySQL servers with this type
myuser#localhost
myotheruser#localhost
now, I want to create new users, that should have the same password as the user above, and have access to the same databases, but from a different host like this:
myuser#127.0.0.1
myotheruser#127.0.0.1
does anyone have a quick and easy way to do this?
I have tried a different approach to this problem, but running these two commands:
mysqldump --skip-extended-insert mysql user | grep 'localhost' | egrep '^INSERT INTO' | sed 's/localhost/127.0.0.1/g' > add-local-ip-user.sql
mysqldump --skip-extended-insert mysql db | grep 'localhost' | egrep '^INSERT INTO' | sed 's/localhost/127.0.0.1/g' > add-local-ip-db.sql
Then, I just output the content:
cat add-local-ip*
then I open mysql:
mysql mysql
and finally just paste the output from above, and run flush privileges does anyone have any objection to doing it this way? e.g. is this a stupid solution?

I can't create a database after logging in mysql under my root account. Do I have to make an admin account to do so? Also, for some reason, my StartUp file didn't install (there was an error). I'm not sure if that will affect anything else since mySQL DOES start up when I type "mysql" into my terminal.
Also when I type in
mysql> SELECT Host, User FROM mysql.user;
+---------------------+------+
| Host | User |
+---------------------+------+
| 127.0.0.1 | root |
| ::1 | root |
| myname-mac.att.net | |
| myname-mac.att.net | root |
| localhost | |
| localhost | root |
+---------------------+------+
Which I don't get. I seem to have multiple root users and I don't know what ::1 means.
EDIT: My databases currently look like this.
mysql> SHOW DATABASES;
+--------------------+
| Database |
+--------------------+
| information_schema |
+--------------------+
1 row in set (0.02 sec)
And it doesn't matter what I type in as my database name. I even tried calling it 'apple'.
It might be problem with space.
Follow this
Check .err logs at /var/lib/mysql
if the log says something like
"[ERROR] Can't start server: can't create PID file: No space left on device"
Check /var size by df -hk /var
if used is 100% , then u have to find the files which is geting filled.
find large file in /var by
find /var/ -type f -size +100000k -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'
see which file you can delete and then restart the mysql process by
/etc/init.d/mysql restart
let me know if that worked :)
If you're on macosx and if you've system preference pane installed, that should show a message like
the following directory is not owned by _mysql user - "/usr/local/msyql/data"
Once you know that path you can do the following:
sudo chown -R mysql:mysql /usr/local/mysql/data
sudo chown -R mysql:mysql <path>
You have one root user for several domains. Meaning you can connect and run queries on that database FROM the specified domains.
If you want to only show one, give it '%' for the domain and remove all others, although that is not advised. Save the root user for run rights only from localhost, and create limited users for running queries from outside.
As for test database error, it happens on fresh installs. Just reboot the mysql server(stop/start process) or the computer.
Also, make sure you have full rights by doing
GRANT ALL PRIVILEGES ON *.* TO 'root'#'thedomainyourunfrom/localhost/%' WITH GRANT OPTION;
this will give your root user full rights across all databases in the server
osx manual http://dev.mysql.com/doc/mysql-macosx-excerpt/5.0/en/macosx-installation.html
As an additional resource, you can try two other things:
Find out the data folder for your MySQL and 'chown' it so that mysql can write properly to it. For example, if your MySQL's data folder is /usr/local/mysql/data/, you can 'chown' it by typing up the command chown -R mysql:mysql /usr/local/mysql/data/
If you have just installed your MySQL server, try restarting your computer. Sometimes the installer fails on giving proper file access to the program
I hope that helps!
The problem I have is when I get into the commandline for mysql I enter as ''#'localhost' and have no access to anything useful, I'm trying at the moment to get data back to a php page so I need a valid username and password. Is there a way I can create a user account with my feeble resources? Is there a way I can enter the MySQL commandline as root?
Any help appreciated.
If you user is root without any password (like a default MySQL setup), you should be able to connect using:
mysql --user=root
If you need to specify pwd as password:
mysql --user=root -ppwd
Check MySQL command line guide for other details.
When you install MySQL, it asks you to enter credentials for the root user.
If you had not done something like that, I recommend you to reinstall.
Moreover, I would recommend you to use a good package like PHPMyadmin to simplify your operations with databases.
http://www.phpmyadmin.net/home_page/news.php
You could also try Xampp, which has everything in a package - PHP, Tomcat, Mercury , Filezilla, PHPMyadmin and more if you'd like. You will spend almost 0 time configuring anything.

Previously, I was getting Access denied... errors for every command, but I was able to resolve the issue after reading RobbieE's suggestion and this documentation:
First, start mysql from the command line as the root user; this is the solution to your original question:
mysql -u root
Now if you'd like to password-protect root...
To see which accounts exist and check their passwords, execute:
SELECT User, Host, Password FROM mysql.user;
You should see an ASCII table, something like this:
+------+--------------------+----------+
| User | Host | Password |
+------+--------------------+----------+
| root | localhost | |
| root | 127.0.0.1 | |
| | localhost | |
+------+--------------------+----------+
Finally, set the password for each root user a la:
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('plaintext-password');
Re-execute statement 2 to verify the password was set correctly. You now have a useful and protected MySQL user for localhost. Do this again for 127.0.0.1 and any other hosts you may have.

Is there any way to grep the output of the MySQL interpretter (CentOS 5.x)? For instance, I know that I need a table with "user" in the table name. Ideally, I would love something like this:
DESCRIBE TABLES; | grep "user"
I know that I can exit MySQL and then do it in bash:
mysql -u me -p "USE someTable; DESCRIBE TABLES;" | grep "user"
But I would prefer to stay in MySQL. Thanks.
Give this a try!
mysql> pager grep user
PAGER set to 'grep user'
mysql> USE someTable;
mysql> DESCRIBE TABLES;
I've just tried it with Mysql v5.0.83, and it does what you would think ;)
You can simply filter tables with a like
show tables like '%user%';
I Have an access to MYSQL Server with more than 2000 Databases in it.
I want to scan all databases to get all email addresses that saved in the tables of databases.
So would you please give me a solution to extract email address from all of databases !?
I already have a root privileges and phpmyadmin.
Thank you
If you have access to all tables (i.e. as root), you can dump all tables and grep email address, like this:
mysqldump -u root -p --all-database | egrep -i "\b[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}\b"
The regular expression I used is taken from here:
http://www.regular-expressions.info/email.html
Edit:
the command above will print the whole rows containing an email address regardless of the column.
If you have email dedicated columns you can print only email with a little modification:
mysqldump -u root -p --all-database | perl -pe "s/,/\n/g; s/'//g;" | egrep -i "\b[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}\b"
This will remove also surrounding quotes.
