way / method to run two or more sites on 1 instance of wp-participants-datbase

[dil_bert]

dear php-experts, dear experts

 

the  question: is there any way / method to run two or more sites on 1 instance of wp-participants-datbase. - see https://wordpress.org/plugins/participants-database/

note: i want to run two or more wordpress-sits /(with different topics and genres – e.g. some of the following:

a. jobs
b. talents / artists
c. job-opportnunities
d. volunteering opportunities
.... and others more.

question: can i work and combine all the four sites onto one instlalation of WP-participants-database?!

What I would like to accomplish is to replicate three or four setups with wordpress like I have on my hoste environment, where one, fully independent WP-paticipants-database installation all sit in the same public_html directory and serves the above mentnioed needs.

so the question is the following - is this possible?!

dear buddies, i hope i was able to spell out what i want to achive. If you have any question – just post.

Years ago i had soemthing similar to do.

now i mused some times about this thing and thought we can do it like so: – regarding the the idea of running on a single database for multiple instances

Well – if we want to go like this and are aiming for the following:
creating two instances of WP on a single domain. For example,

Like so:

wp1.domain.com and
wp2.domain.com ….to use a single database (same comments/posts and yes: same Participant-database-plugin that you mention – cf. https://wordpress.org/plugins/participants-database/ )

The simplest way of doing that is just conditionally defining the environment variables in wp-config.php like this:

/** Define alternate home and siteurl based on $_SERVER host var */
if ( strpos ( $_SERVER['SERVER_NAME'], 'wp2' ) !== false ) {
    define( 'WP_HOME', 'http://wp2.domain.com' );
    define( 'WP_SITEURL', 'http://wp2.domain.com' );
}

with this – i guess that this may do the trick:

What do you think!?

further Assumptions: This is really a MySQL question but yes. we could create a master database and slave databases on the other servers. All PHP access is done to the local database but the slaves and master are kept in sync by MySQL.
