如何在 VirtualBoxVagrant 中连接到 Mysql 服务器？

Make sure MySQL binds to 0.0.0.0 and not 127.0.0.1 or it will not be accessible from outside the machine

You can ensure this by editing the /etc/mysql/my.conf file and looking for the bind-address item--you want it to look like bind-address = 0.0.0.0. Then save this and restart MySQL:

sudo service mysql restart

If you are doing this on a production server, you want to be aware of the security implications, discussed here: https://serverfault.com/questions/257513/how-bad-is-setting-mysqls-bind-address-to-0-0-0-0

Log in to your box with ssh vagrant@127.0.0.1 -p 2222 (password vagrant)

Then: sudo nano /etc/mysql/my.cnf and comment out the following lines with #

#skip-external-locking
#bind-address

save it & exit

then: sudo service mysql restart

Then you can connect through SSH to your MySQL server.

For anyone trying to do this using mysql workbench or sequel pro these are the inputs:

Mysql Host: 192.168.56.101 (or ip that you choose for it)
username: root (or mysql username u created)
password: **** (your mysql password)
database: optional
port: optional (unless you chose another port, defaults to 3306)


ssh host: 192.168.56.101 (or ip that you choose for this vm, like above)
ssh user: vagrant (vagrants default username)
ssh password: vagrant (vagrants default password)
ssh port: optional (unless you chose another)

I came across this issue recently. I used PuPHPet to generate a config.

To connect to MySQL through SSH, the "vagrant" password was not working for me, instead I had to authenticate through the SSH key file.

To connect with MySQL Workbench

Connection method

Standard TCP/IP over SSH

SSH

Hostname: 127.0.0.1:2222 (forwarded SSH port)
Username: vagrant
Password: (do not use)
SSH Key File: C:\vagrantpath\puphpet\files\dot\ssh\insecure_private_key
(Locate your insercure_private_key)

MySQL

Server Port: 3306
username: (root, or username)
password: (password)

Test the connection.

Well, since neither of the given replies helped me, I had to look more, and found solution in this article.

And the answer in a nutshell is the following:

Connecting to MySQL using MySQL Workbench

Connection Method: Standard TCP/IP over SSH
SSH Hostname: <Local VM IP Address (set in PuPHPet)>
SSH Username: vagrant (the default username)
SSH Password: vagrant (the default password)
MySQL Hostname: 127.0.0.1
MySQL Server Port: 3306
Username: root
Password: <MySQL Root Password (set in PuPHPet)>

Using given approach I was able to connect to mysql database in vagrant from host Ubuntu machine using MySQL Workbench and also using Valentina Studio.

This worked for me: Connect to MySQL in Vagrant

username: vagrant password: vagrant


sudo apt-get update sudo apt-get install build-essential zlib1g-dev
git-core sqlite3 libsqlite3-dev sudo aptitude install mysql-server
mysql-client




sudo nano /etc/mysql/my.cnf change: bind-address            = 0.0.0.0




mysql -u root -p


use mysql GRANT ALL ON *.* to root@'33.33.33.1' IDENTIFIED BY
'jarvis'; FLUSH PRIVILEGES; exit




sudo /etc/init.d/mysql restart

end

Here are the steps that worked for me after logging into the box:

Locate MySQL configuration file:

$ mysql --help | grep -A 1 "Default options"


Default options are read from the following files in the given order: /etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf

On Ubuntu 16, the path is typically /etc/mysql/mysql.conf.d/mysqld.cnf

Change configuration file for bind-address:

If it exists, change the value as follows. If it doesn't exist, add it anywhere in the [mysqld] section.

bind-address = 0.0.0.0

Save your changes to the configuration file and restart the MySQL service.

service mysql restart

Create / Grant access to database user:

Connect to the MySQL database as the root user and run the following SQL commands:

mysql> CREATE USER 'username'@'%' IDENTIFIED BY 'password';


mysql> GRANT ALL PRIVILEGES ON mydb.* TO 'username'@'%';
