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: Yosemite, Guest: Trusty, vagrant 1.7.4
Vagrantfile(host):
config.vm.network "forwarded_port", guest: 80, host: 8080
config.vm.network "forwarded_port", guest: 3306, host: 3309
my.ini(guest):
bind-address = 127.0.0.1
8080 forwarding works like a charm.
mysql -h127.0.0.1 -uroot -p from guest also works.
mysql -h127.0.0.1 -P 3309 -uroot -p from host results with reading initial communication packet error.
When I telnet from host, the connection instantly closes:
$ telnet localhost 3309
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
Port forwarding works when I ssh to vagrant box from host:
$ssh vagrant@127.0.0.1 -p 2222 -L3308:localhost:3306
Then I can connect from host mysql -h127.0.0.1 -P3308 -uroot -p without problems, which I use as a temporary workaround.
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:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 36
Server version: 5.5.44-0ubuntu0.12.04.1 (Ubuntu)
The first answer is right but not enough.when I connect MySQL, I get a error:
Host '10.0.2.2' is not allowed to connect to this MySQL server
Solution:
create user 'root'@'10.0.2.2' identified by 'password';
grant all privileges on . to 'root'@'10.0.2.2' with grant option;
flush privileges;
aha, all problems are solved,
Personally I don't bother with modifying MySQL for development Vagrant boxes - it's time consuming and difficult to script in a provisioner meaning you have to do it by hand every time you vagrany destroy or a new developer starts contributing. Instead, I connect via SSH Tunnel which is made super easy using Vagrant's generated private_key file. No additional post-install tweaking necessary.
Follow these steps to SSH Tunnel with SequelPro, MySql Workbench, or any other client that supports SSH connectivity:
- Choose SSH connection option
- The "Host" in SSH mode becomes localhost or specifically
127.0.0.1 (more predictable cross-os)
- The username/password is the database username/password. For development you can just use
root and the password is defined/created in the provisioner (see snippet below)
- The SSH username is
Vagrant
- No SSH password - just use the
private_key for the Vagrant machine instead, located in .vagrant/machines/default/virtualbox in the root of your VM project; note that on most OS's this directory, and all starting with a . are hidden
To automate installation and root password creation, add this to your Vagrant provisioner script file (config.vm.provision in Vagrantfile), commonly named provisioner.sh:
debconf-set-selections <<< 'mysql-server mysql-server/root_password password SuperSecretPasswordHere'
debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password SuperSecretPasswordHere'
apt-get install -y mysql-server
Hope this helps save someone else some time!
