Connect to MySQL from outside vagrant

Question

I would like to connect with mycli to the MySQL server running inside a vagrant instance.

My basic Vagrantfile looks like the following code snippet:

Answer 1

If you are connecting from outside of the vm, you'll need to add a port mapping that listens on the host and forwards requests to the guest. Similar to the one defined for http here:

config.vm.network "forwarded_port", guest: 80, host: 8082

For mysql (assuming your mysql listens on the default port):

config.vm.network "forwarded_port", guest: 3306, host: 33060

After, modifying the Vagrant file, vagrant reload.

Then when connecting, specify the port

mysql -P 33060 -u user -p database

Answer 2

on top of what JRD said on the port forwarding, you need to make sure mysql listens on all port and not just locally

edit the /etc/mysql/my.cnf file and make sure, either

• you have bind-address = 0.0.0.0
• or you comment the line #bind-address ...

make sure to restart your mysql server after the change

$ sudo service mysql restart

Then you can connect from your host - In case you get the following error

$ mysql -h127.0.0.1 -P 33600 -uroot -p
Enter password:
ERROR 1130 (HY000): Host '172.16.42.2' is not allowed to connect to this MySQL server

Then came back to the guest and do

vagrant@precise64:~$ mysql -h127.0.0.1 -uroot -p
...
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.42.2' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

Then you should have no issue to connect from the host machine

$ mysql -h127.0.0.1 -P 33600 -uroot -p
Enter password:
