Some vagrant related useful notes

These are some useful vagrant related notes from me.

Performance

We all know that vagrant boot up is a bit slow, especially provisioning so you should do your best to increase the performance inside and outside. You can play with RAM and CPU configs in Vagrantfile. On top of that you can use vagrant-cachier tool.

Most used commands

To read what commands below do in more detail, visit CLI page.

• vagrant up - Installs a box or starts existing one.


• vagrant halt - Stops running session.


• vagrant reload - Reloads box.


• vagrant reload --provision - Reloads box with running bootstrap scripts.


• vagrant global-status - List all vagrant machines in the system and their current statuses.


• vagrant global-status --prune - Removes all listed but non-existent vagrant machines from the system. (If you deleted a vagrant project folder manually, you won't be able to kill registered vagrant boxes/machines. This will cause you problems when trying to add a new box in the future. To get rid of this problem, use this command.)


• vagrant destroy [name/id] - Removes vagrant machines from the system.

Some notes

• When you run vagrant box add ubuntu/trusty64 command, it will add the box to filesystem so you don't need to run it again in future for the same box. For the new projects, just place Vagrantfile in the project folder and run vagrant init ubuntu/trusty64 command.


• Global folder of vagrant is: ~/.vagrant.d/.


• Test if apache is working in vagrant box: wget -qO- 127.0.0.1.


• If you feel there is something wrong with a command in "bootstrap.sh" file then remove > /dev/null 2>&1 from the line to see what actually happens with the command.


• If you don't replace default phpMyAdmin password with root then you won't be able see all the databases when in GUI.

phpMyAdmin settings

Where phpMyAdmin GUI settings are.

/etc/phpmyadmin/config-db.php

Where phpMyAdmin GUI settings above are originated from.

/etc/dbconfig-common/phpmyadmin.conf
