Drupal 8 notes – Transfer site to local system for development

Posted on June 10, 2020 by jess

These are procedures and notes to download source code and database content for development use on a local workstation server. The goal is create a mirror of the Drupal based website for local development and testing.

Prerequisites

You should have a local or alternate development system ready. This systems will require a web server running PHP and a database compatible with MySQL. Typically this system should be similar to the system hosting the server you wish to make a copy of for development purposes.

Other tools used on the local system include:

PHP-Composer – installed globally
Node / npm – installed globally
Drush – installed globally
Git – installed globally

Transfer Procedures

Export configuration sync package from remote server.
A. Visit Configurations > Configuration Synchronization.
B. Visit Export tab.
C. Download Export file and keep for local set up.
Download Git Repo
Perform composer update:
composer update drupal/core-recommended –with-dependencies
Download Drupal Database
Install Database for git website. May require your own settings.php file in /sites/default
!!! – Website should load at this point.
!!! Deactivate secure login to stop https redirects:
drush pm-uninstall securelogin
Log in.
Visit Configurations > Configuration Synchronization. There may be an error for a missing directory. Make sure you create that missing directory path.
Visit Import tab.
Upload file saved in step #1 > C.
Follow upload with “Install All” on Synchronize Import screen.
It’s always a good idea to clear the Drupal Cache: Either with Drush if working:
drush cache:rebuild
or by visiting options under Configuration > Performance.
They may be fine, but you may also check database updates with Drush:
drush updatedb

NPM and Yeoman update/install notes for MacOS

Posted on July 28, 2016July 28, 2016 by jess

Had to deal with some issues introduced by bad homebrew installations and possible old NPM installs. My guess is that I probably cheated/screwed up using a sudo install when I should have done something different.

This all started playing with the WebDevStudions WordPress plugin generator for yeoman.

Get a Plugin Kickstart with Yeoman & generator-plugin-wp!

This gist was very helpful – Fixing npm On Mac OS X for Homebrew Users

Another strange issue was caused by installing the generator-plugin-wp yoeman generator on a broken yeoman/npm system. This posted github issue helped. https://github.com/npm/npm/issues/10995 This needed a straightforward uninstall, cache clear, and reinstall. I may have reintialized my terminal sessions to drop out of sudo mode. It looked something like:

$ sudo npm remove -g yo generator-plugin-wp
$ npm cache clean
-- can't remember if I relaunched terminal to drop out of sudo mode.
$ npm install -g generator-plugin-wp

I’ll be testing this yeoman generator on the side for a while: https://github.com/WebDevStudios/generator-plugin-wp

Spying on a directory with auditd

Posted on September 11, 2015September 11, 2015 by jess

Files start coming up missing for me on a server and I get freaked out looking for security holes, but sometimes users and other utilities are spiking the bunch bowl. You can get serious with watching files with other utilities, but I went back to good ole auditd.

A simple test to track stuff getting trashed from an upload folder:

auditctl -w /site-dir/wp-content/uploads/ -p wa -k upload_issue

A capital W will remove the rule:

auditctl -W /site-dir/wp-content/uploads/ -p wa -k upload_issue

Do a quick search for issues with ausearch.

ausearch -f wp-content/uploads

Now permanently add the rule on a redhat system by putting this line in /etc/audit/audit.rules. Just leave off the auditctl command.

 -w /site-dir/wp-content/uploads/ -p wa -k upload_issue

Of course you need to make sure your auditd process is running and using chkconfig, etc. Good ole check status like:

/etc/init.d/auditd status

Here are a few of the resources I used:

Please forgive the RedHat auth-walls…

My Favorite Httrack commands

Posted on September 11, 2015September 11, 2015 by jess

HTTrack is a website mirroring utility that can swamp your disks with mirror copies of the internet. I’ve had to use it several times to make off-line copies of websites for all sorts of weird reasons. You’ll find HTTrack at: www.httrack.com. You can get a full list of command line options at: https://www.httrack.com/html/fcguide.html. There is a spiffy web and Windows wizard interface for HTTrack, but I gave that up.

This is the recipe for the command line options I’ve been using to produce a browse-able offline version of accreditation documents. This command says “Make an offline mirror of these URLs, go up to 8 links deep on these sites and 2 links deep on other domains. Stay on the TLD (.edu) and do it as quickly as possible. Be warned as it currently stands this will fill up about 1.5GB of disk space ;P.

httrack http://www.nicholls.edu/sacscoc-2016/ http://www.nicholls.edu/catalog/2014-2015/html/ http://www.nicholls.edu/about/ -O /Users/nichweb/web-test -r8 -%e1 -%c16 -*c16 -B -l -%P -A200000

The great part is that the archive grows as URLs are added.

Apache log one-liners using tail, awk, sort, etc.

Using HyperDB to separate and share user and user_meta between WordPress installations

Posted on April 8, 2015April 8, 2015 by jess

I need to remember to keep this example for some testing. This should be a good start for sharing a user and user_meta between websites. I do know that user_meta tends to have very site-centric settings at times. Original article was located at: http://wordpress.aspcode.net/view/63538464303732726666099/how-to-use-hyperdb-to-separate-and-share-a-user-dataset-between-wordpress-installs

$wpdb->add_database(array( //Connect to Users Database
    'host'     => DB_HOST, // I am using the same host for my two DBs
    'user'     => DB_USER, // I am using the same username for my two DBs
    'password' => DB_PASSWORD, // I am using the same p/w for my two DBs
    'name'     => 'my_user_db_name', 
    'write'    => 0, // Change to 1 if you want your slave site's the power to update user data.
    'read'     => 1,
    'dataset'  => 'user',
    'timeout'  => 0.2,
));

$wpdb->add_database(array( // Main Database
    'host'     => DB_HOST,
    'user'     => DB_USER,
    'password' => DB_PASSWORD,
    'name'     => DB_NAME,
));

$wpdb->add_callback('user_callback');
function user_callback($query, $wpdb) {
    if ( $wpdb->base_prefix . 'users' == $wpdb->table || $wpdb->base_prefix . 'user_meta' == $wpdb->table) {
        return 'user'; 
    }
}
