Vagrant port forwarding for Mysql

Question

I am trying to setup port forwarding in Vagrantfile to connect to guest mysqld from host system, but get reading initial communication packet error. Host: Yosem

Answer 1

was finally able to make it work -

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 ...

You may need to add it to the mysqld section of the my.cnf file:

[mysqld]
bind-address = 0.0.0.0

make sure to restart your mysql server after the change

$ sudo service mysql restart

Then you can connect from your host - so I first had an error like

$ mysql -h127.0.0.1 -P 3309 -uroot -p
Enter password:
ERROR 1130 (HY000): Host '172.16.42.2' is not allowed to connect to this MySQL server

so I came back to the guest and did

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 I had no issue to connect from the host machine

$ mysql -h127.0.0.1 -P 3309 -uroot -p
Enter password:
