I used `brew install mysql-client' and it installed the client but I have no access to manual help on this. What is the way to connect with a url mysql://db.dev.dev.ms-df-cloudrdbms.glb.us.net:3306/cx_cortex for instance ? Do I have to also install mysql server to connect or is there a client?
Mysql client command is quite easy to use:
mysql -h mysqlhost.mycompany.com -u root -p db_name
-h host
-u user
-p (input password by typing it or in the command line)
For help, you can try:
mysql --help

I have Mysql installed on my local PC and want to use mysqldump on my local pc to dump a remote database. So I open CMD and run the following command:
mysqldump -P 3306 -h 12.43.33.43 -u admin -p myDatabase > mydb.sql
So in the next line it should ask for my password? but instead i get the response 'Access is denied'. Am i missing something here?
ps.
If I try the following:
mysqldump -P 3306 -h 12.43.33.43 -u admin -p myDatabase
it will successfully ask for my password and start printing the dump in cmd, but this is no good as i need the response saved in a file.
I only wanted to know if you could connect.
The command is
mysqldump -P 3306 -h 12.43.33.43 -u admin -p --databases myDatabase --result-file=mydb.sql
As the connection is not secure, you send your credentials like a postcard, so that every one can read it.
Besides that having your server exposed to the internet, is very dangerous and can come to a disaster, so reconsider your security strategy and allow only access via ssh.
I am trying to connect to MySQL database from MySQL shell on windows.
No matter what I type in MySQL shell, it keeps giving me error : 'Not connected'.
Query eg 1 : mysql --host=localhost --port=3306 --user=root -p;
Query eg 2 : mysql -u root -p
O/P : ERROR: Not connected
I have MySQL server installed on my machine. Also MySQL service is running in the background.
Also, I was able to connect from MySQL workbench.
ERROR MESSAGE
MySQL Workbench Connection
My temporary workaround is that I make use of ssl protocol to connect to MySQL server :
MySQL> \connect root#localhost
MySQL localhost:33060+ ssl SQL > show databases;
The first step is that you need to check if you are in the MYSQL Shell SQL mode or JS mode.
Then if you are in SQL mode then you are good to go else you need to switch to SQL mode by this command
\sql
The next step is to connect using this command
\connect root#localhost
In your case, you might have given the privilege as the IP address so you need to check your localhost IP which can be done by this command in your command prompt.
ipconfig and then just check the IP address and put it in place of localhost in the previous command. If this still doesn't works then put 127.0.0.1:3306.
After this, it will prompt to add or save the password , enter a unique password there.
After this you are good to go and check the user and localhost after this by this command
SELECT user, host FROM mysql.user;
Try mysql -u root -p
I haven't used MySQL shell, I typically use gitbash and it works just fine
I had faced the same issue on my Windows 10 machine with MySQL 5.7 and the following commands helped me:
mysqlsh.exe - to open mysql shell; then
\sql - to start working with SQL;
finally:
\connect root#127.0.0.1:3306
You can use:
mysql -uroot -hlocalhost -P3306 -p
or
mysql -uroot -h127.0.0.1 -P3306 -p
or
mysql -uroot -p
I have gone through similar cases listed here but it doesn't seem to work.
I was using MySQL Workbench to establish a connection with my database which is hosted on another server. Tried a few times and unable to connect followed by this error. I am confused as to where I should even do this flush. On PhpMyadmin under the SQL query? Cos when I tried to input the following command, it returns as syntax error. I am using a windows OS thus no shell shell scripting for me to input this information either. I am accessing the database temporarily via Cpanel/ phpmyadmin now.
Please help to tell where I should input this data and if my syntax is wrong. Thanks for help.
mysqladmin flush-hosts;
or
mysqladmin -umyname -pmypassword flush-hosts;
My error message as follows:
Failed to connect to MYSql at 192...* with user myName
Host 'host-92...*.as13285.net' is blocked because of many connection
errors; unblock with 'mysqladmin flush-hosts'
mysqladmin is not a SQL statement. It's a little helper utility program you'll find on your MySQL server... and "flush-hosts" is one of the things it can do. ("status" and "shutdown" are a couple of other things that come to mind).
You type that command from a shell prompt.
Alternately, from your query browser (such as phpMyAdmin), the SQL statement you're looking for is simply this:
FLUSH HOSTS;
http://dev.mysql.com/doc/refman/5.6/en/flush.html
http://dev.mysql.com/doc/refman/5.6/en/mysqladmin.html
You should put it into command line in windows.
mysqladmin -u [username] -p flush-hosts
**** [MySQL password]
or
mysqladmin flush-hosts -u [username] -p
**** [MySQL password]
For network login use the following command:
mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts
you can permanently solution your problem by editing my.ini file[Mysql configuration file]
change variables max_connections = 10000;
or
login into MySQL using command line -
mysql -u [username] -p
**** [MySQL password]
put the below command into MySQL window
SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;
check veritable using command-
show variables like "max_connections";
show variables like "max_connect_errors";
You can easily restart your MySql service. This kicks the error off.
I downloaded the mysql dmg file and went through the wizard to run. Done. I have also started mysql server under system preferences.
The purpose of me doing this is to work through the exercises of my SQL text book. The terminal commands are new to me but I think once I can actually get started, working through the exercises should be OK.
From researching the web the various blogs tell me to navigate to to the mysql folder in the terminal:
/usr/local/mysql
Fine. Then it gets a little less clear as nearly each article has a different set of instructions on how to proceed. I was fiddling with it yesterday and was prompted for a password - what is the default mysql password?
Could someone give me the steps to get up and running with mysql via the terminal?
(Updated for 2017)
When you installed MySQL it generated a password for the root user. You can connect using
/usr/local/mysql/bin/mysql -u root -p
and type in the generated password.
Previously, the root user in MySQL used to not have a password and could only connect from localhost. So you would connect using
/usr/local/mysql/bin/mysql -u root
open terminal and type
sudo sh -c 'echo /usr/local/mysql/bin > /etc/paths.d/mysql'
then close terminal and open a new terminal and type
mysql -u root -p
hit enter, and it will ask you for password
I have found this solution on https://teamtreehouse.com/community/says-mysql-command-not-found
now to set new password type
ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
In the terminal, I typed:
/usr/local/mysql/bin/mysql -u root -p
I was then prompted to enter the temporary password that was given to me upon completion of the installation.
In MacOS, Mysql's executable file is located in /usr/local/mysql/bin/mysql and you can easily login to it with the following command:
/usr/local/mysql/bin/mysql -u USERNAME -p
But this is a very long command and very boring, so you can add mysql path to Os's Environment variable and access to it much easier.
For macOS Catalina and later
Starting with macOS Catalina, Mac devices use zsh as the default login shell and interactive shell and you have to update .zprofile file in your home directory.
echo 'export PATH="$PATH:/usr/local/mysql/bin"' >> ~/.zprofile
source ~/.zprofile
mysql -u USERNAME -p
For macOS Mojave and earlier
Although you can always switch to zsh, bash is the default shell in macOS Mojave and earlier and with bash you have to update .bash_profile file.
echo 'export PATH="$PATH:/usr/local/mysql/bin"' >> ~/.bash_profile
source ~/.bash_profile
mysql -u USERNAME -p
install homebrew via terminal
brew install mysql
This command works for me:
./mysql -u root -p
(PS: I'm working on mac through terminal)
In terminal
sudo sh -c 'echo /usr/local/mysql/bin > /etc/paths.d/mysql'
Close that and open new terminal
mysql -u root -p
Give your password
For mac OS Catalina :
/usr/local/mysql/bin/mysql -uroot -p
This will prompt you to enter password of mysql
You can simply type in Terminal
brew services start mysql
if you installed mysql via brew on mac
If you have your MySQL server up and running, then you just need a client to connect to it and start practicing. One is the mysql-client, which is a command-line tool, or you can use phpMyAdmin, which is a web-based tool.
This command works for me:
Command:
mysql --host=localhost -uroot -proot
try with either of the 2 below commands
/usr/local/mysql/bin/mysql -uroot
-- OR --
/usr/local/Cellar/mysql/<version>/bin/mysql -uroot
I have XAMPP running on my desktop and can connect to the MySQL server via phpMyAdmin. However, when I try to connect through Cygwin:
Error: Can't connect to local MySQL server through socket '/var/run/mysql.sock' (2)
I've tried connecting to MySQL on the same machine, my local dev server and my remote server, all failed.
mysql -h 127.0.0.1 -P <PORT> -u root -p
This is what worked for me. Make sure you check what is the correct port.
Check the mysqld PID with:
ps -sW | grep mysqld
And then find the PORT with:
netstat -nao | grep <PID>
Have fun!
you can also add the alias of itself.
alias mysql = 'mysql -u {user} -p{password} -h 127.0.0.1'
