Accessing multisite WordPress from a database dump on Vagrant.

multisite-on-vagrant.md

Assumptions:

• A WordPress multisite database loaded on your Vagrant box, accessible at vagrant.dev with the IP address 192.168.33.10 (See your Vagrantfile and /etc/hosts)
• WordPress already installed and configured on your Vagrant box
• WP-CLI installed on your Vagrant box
• The main site of your network is network.org and the project site is project.org
• If you do not possess admin credentials for the network, we will create a new admin, whose username is admin and whose password is password.
• If you want to be able to undo this, run vagrant plugin install vagrant-vbox-snapshot from the Vagrant host. To take a snapshot, run vagrant snapshot take default [optional-name-for-snapshot]. Take one before starting, and then at the start of every major section here.

Getting multisite set up:

Correcting the network site name:

Grab Version 2.x of https://interconnectit.com/products/search-and-replace-for-wordpress-databases/ and unzip it into the root of your Vagrant site. That's either into /vagrant or into the folder containing the wordpress install. Either way, it should be in the same folder as wp-config.php.

Visit http://vagrant.dev/searchreplacedb2.php in your browser.

1. Check "Pre-populate the DB values"
2. Click "Submit"
3. Check that the values look right. If you're using our Vagrantfile from deploy-tools, it will be localhost, largoproject, root, root, utf8.
4. There is a multi-select of database tables. Most will be prefixed with wp_#_, as opposed to wp_. Ctrl-click or shift-click to choose the non-number-prefixed tables.
5. Check 'Leave GUID column unchaged'
6. Search for network.org and replace with vagrant.dev
7. Submit search string.

Open wp-config.php and add the follwing lines:

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'vagrant.dev');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

Adding a new super-user

This is only necessary if you do not possess the credentials for a network super-admin.

vagrant ssh
cd /vagrant
wp user create admin admin@vagrant.dev --role=administrator --user_pass=password
wp super-admin add admin

You should now be able to log into http://vagrant.dev/wp-login.php as admin with password.

Getting access to the sites on your multisite

Add your user to project.org

You only need to do this if your admin user does not have access to project.org.

Log into your multisite install at http://vagrant.dev/wp-login.php.

1. In the header, choose My Sites > Network Admin > Sites (http://vagrant.dev/wp-admin/network/sites.php)
2. Find the project.org site. Click on its "Edit" button.
3. Find the site's URL near the top of the page: "Edit Site: project.org" or "Edit Site: project.vagrant.dev"
4. Edit your host computer's /etc/hosts file by adding the line 192.168.33.10 project.vagrant.dev to the end of the file.
5. Check that http://project.vagrant.dev points to the correct site.
6. Click the "Users" tab.
7. Under "Add Existing User", enter admin as the username and choose the "Administrator" role.

Find the blog ID of project.org

1. Go to http://vagrant.dev/wp-admin/network/sites.php
2. Find the project.org site. Click on its "Edit" button.
3. Find the site's URL near the top of the page: "Edit Site: project.org" or "Edit Site: project.vagrant.dev"
4. Find the ID number in the browser's current URL: http://vagrant.dev/wp-admin/network/site-info.php?id=53
5. Copy down the blog ID number. We'll use it in the next step.

Convert project.org to project.vagrant.dev

This process will be familiar, with one key difference.

Visit http://vagrant.dev/searchreplacedb2.php in your browser.

1. Check "Pre-populate the DB values"
2. Click "Submit"
3. Check that the values look right. If you're using our Vagrantfile from deploy-tools, it will be localhost, largoproject, root, root, utf8.
4. There is a multi-select of database tables. Ctrl-click or shift-click to choose the tables prefixed with wp_53_, where 53 is the site id.
5. Check 'Leave GUID column unchaged'
6. Search for project.org and replace with project.vagrant.dev
7. Submit search string.
8. Wait. The page will load for a loooong time.
9. If you get to a page with a success message, congratulations!
   "In the process of replacing "project.org" with "project.vagrant.dev" we scanned 33 tables with a total of 610470 rows, 71588 cells were changed and 71560 db update performed and it all took 958.267747 seconds."
10. If the next page is mostly or entirely blank after the header, then you will need to use a different tool to perform the replace.

You should now be able to log in as admin with password at http://project.vagrant.dev/wp-login.php
